The iPhone has enabled all sorts of crazy interactions, but a new device called Cue could be the first iOS accessory that uses boogers as a primary user input. The tabletop analyzer brings the power of a medical laboratory into the home and allows people to test their levels of testosterone, inflammation, vitamin D, and fertility with small amounts of blood, saliva, or nasal swabs.
Greenville, South Carolina – Span-America officials recently introduced a new addition to the company’s PressureGuard series of specialty air therapy surfaces. The PressureGuard Protocol features Span's high-performance microclimate management technology, which is indicated for excessive skin moisture caused by perspiration. Excess moisture can lead to maceration, which is a weakening of the skin that can cause pressure ulcers, make them worse, or prevent them from healing. By providing effective skin moisture management, the new offering delivers a highly effective combination of both prevention and treatment of Stage I through IV pressure ulcers. The design of Span's patented direct delivery cover facilitates a gentle flow of air from the quiet, energy efficient control unit.
This operation presents a sharp contrast to typical low air loss systems, whose high output blowers generate more noise and heat while using more power. Vulnerable skin is protected by the uninterrupted flow of air directly to the underside of its vapor-permeable but fluid-proof coverlet, where it interacts with moisture vapor from the user's skin. Moisture vapor is then swept away before it can re-form as a liquid, reducing maceration – an outcome that is especially desirable at the vulnerable sacrum. Unlike typical low air loss designs, the Air Diffusion Matrix fabric is not collapsed by the user's weight, ensuring a pathway for a constant flow of air beneath the user.
The new Protocol surface includes several additional features that can be indispensable in modern resident care – gentle alternating pressure therapy to promote improved circulation and healing, and powered flotation treatment modes which provide additional surface stability for ADLs, transfers, and feeding.
Span's years of development and engineering for the long-term care environment are evident in the PressureGuard platform. It includes features such as the Geo-Matt style foam topper, a high density, medical grade foam with a geometric design consisting of over 800 individual cells. Each cell acts individually to customize patient support, comfort, and pressure reduction. This segmentation minimizes the pulling of the skin and tissue over bony prominences, offsetting the harmful effects of shearing. The Heel Slope at the topper's foot end is designed to further reduce pressure at the sensitive heel.
Another PressureGuard feature with multiple advantages is the Safety Edge, which helps prevent falls and user entrapment between the side-rail and the mattress. The two-part foam bolster system provides a firmer surface for edge-of-bed sitting and encourages the supine user towards the center of the mattress, increasing compliance with bed safety guidelines.

Indianapolis, Indiana – Indy Composite Works (ICW) collaborated with the doctors and staff of the Indiana University Health Proton Therapy Center in Bloomington, Ind., to design and manufacture a customized carbon fiber patient treatment table that has significantly improved the flexibility and precision of proton therapy while increasing patient comfort.
“When we contacted ICW in 2011, we were one of only nine proton therapy centers in the country, and there were few companies developing products for proton therapy needs. The tables available did not meet our needs for the complex case mix of patients that we could treat,” says Dr. Jeffrey Buchsbaum, a radiation oncologist at the IU Health Proton Therapy Center.
Proton therapy utilizes a concentrated beam of radiation, which spares normal surrounding tissues from exposure, having fewer long-term effects on organs and limiting tumor risks later in life. There are many challenges specific to craniospinal irradiation (CSI) cases, where patients receive radiation to the brain and spinal cord. Prior to the new table, CSI patients had to lie on their stomachs, which made using anesthesia for children less safe and difficult to protect the vocal cords. In addition, the precision of the therapy makes it critical for patients to remain in the same position for up to one hour, difficult especially for children, which makes up about 30% of the center’s patients.
“A customized table became critical in providing the absolute best positioning of adults and children during treatment,” continues Dr. Buchsbaum.
The new treatment table design allow CSI patients to be more comfortable in the supine position (on the back), and anesthesia can be delivered with greater ease, particularly important when dealing with young patients. The staff indicates that the tables have helped increase productivity and improved work flow.
“The new tables have given the IU Health Proton Therapy Center the ability to treat a wide variety of conditions,” states Victor Simoneaux, BS (R), (T), and chief radiation therapist at the center. “We have developed new methods for treating adults and children with tumors of the brain, head and neck, thorax, abdomen, pelvis and extremities. These treatment methods were not possible before ICW created our patient table, which is a fundamental part of what we do every day, impacting about 50% of our patients.”
Indy Composite Works business comprises much more than the average composite work performed out in the market. “Our professionals design and manufacture precisely engineered composites that meet very specific needs, such as the patient table,” says Dave New, vice president of ICW. “Many clients come to us because the products available in the market do not meet their specific needs or do not perform in the way required. Through close work with the client and innovation, ICW delivers the needed product.”
“Our collaboration with ICW was a fantastic experience,” states Dr. Buchsbaum. “ICW made several trips to the center to discuss the table with our team and to learn about our treatment. We also visited their shop to meet with their engineering team. Every step of the way, we had discussions and reviews about the measurement of table flexion, safety issues, and proton beam design needs. ICW took on this project with passion, and showed real concern because it was going to be used to help our cancer patients, particularly the children.”
“ICW took our ideas and needs and worked with us with CAD drawings and several prototypes. We knew what we wanted, and the ICW team knew what could be manufactured to create a solution. It was truly a collaborative effort to come up with a design that was functional, innovative, and producible. In the end, they surpassed our expectations,” concluded Buchsbaum.

Parsippany, N.J. – Extremity Medical LLC, an entrepreneurial-based manufacturer of orthopedic implants for the distal extremities, has received 510(k) clearance from the U.S. Food & Drug Administration (FDA) for its new HammerFiX IP fusion system made of Zeniva polyetheretherketone (PEEK) resin from Solvay Specialty Polymers. Zeniva PEEK – part of Solvay’s line of Solviva Biomaterials – has a modulus very close to that of bone plus excellent toughness and fatigue resistance. The FDA clearance was based in part on Solvay’s well-developed master access file for Zeniva PEEK. The HammerFiX implant is the first cannulated hammertoe device made of the non-resorbable polymer PEEK in the U.S., according to Jamy Gannoe, Extremity Medical’s president and co-founder. It is used for the fixation of osteotomies and reconstruction of the lesser toes following correction procedures for hammertoe, claw toe, and mallet toe.
“Zeniva PEEK’s exceptional properties have enabled us to develop a next-generation hammertoe fixation product that is differentiated among our competition in terms of material and design,” said Gannoe.
The HammerFiX implant, machined from 6mm-diameter Zeniva PEEK rod stock, was designed for stability and maintenance of the correction. The inherent elasticity of Zeniva PEEK aids in the delivery of the implant in the phalanx. The reverse helical thread pattern of the implant’s barbed segment allows for a technique which provides additional compression across the joint.
The implant’s design also provides an option to temporarily pin the corrected phalanx to the metatarsal with a guide wire in order to minimize metatarsophalangeal joint subluxation during healing. Zeniva PEEK is also radiolucent which enables the surgeon to better visualize the fusion site via x-ray without the shadows and opacity of titanium.
The HammerFiX implant comes in three sizes – 2.8mm, 3.4mm, and 4mm – to accommodate the size variation of the phalanges.
“This application demonstrates the superior toughness and ductility of Zeniva PEEK over the competition,” said Shawn Shorrock, Global Director of Regulatory Affairs for Solvay Specialty Polymers’ healthcare business. “These unique properties, plus the well-established history of biological safety for Zeniva PEEK, will continue to support its growth in the orthopedic market.”
The manufacturing site for Zeniva PEEK and other Solviva Biomaterials in Alpharetta, Ga., is ISO 13485 registered and the relevant aspects of current Good Manufacturing Practices are also applied. Solvay’s biomaterial manufacturing processes are carefully validated and enhanced controls provide product traceability. In addition, all materials are tested in an ISO 17025 accredited lab.
In addition to Zeniva PEEK, Solvay’s Solviva Biomaterials line includes Proniva self-reinforced polyphenylene (SRP), one of the world’s stiffest and strongest unreinforced thermoplastics which offers exceptional biocompatibility and hardness; Veriva polyphenylsulfone (PPSU), which provides unsurpassed toughness combined with transparency and excellent biocompatibility; and Eviva polysulfone (PSU), which offers toughness in a strong, transparent polymer.
Chicago – Make plans to attend the IMTS 2014 Conferences to learn about Using Simulation Software to Achieve True "Lights-Out" Machining.
DATE: Monday, September 8 from 3:15 PM - 4:10 PM ROOM: W-192C
SPEAKER: Gene Granata, Technical Support Manager, CGTech
This presentation will demonstrate how lights-out machining--of even the first part--can be a reality. Using case-study examples, the audience will learn how other manufacturers have overcome some of the challenges to achieving completely unattended CNC machining. Specific features of the NC verification, simulation, and optimization software that are required to establish total confidence in the offline prove-out process will be discussed.
- Many manufacturers are looking to automation to increase efficiency without adding to labor costs.
- Some of the efficiency gains that automation offers are lost in the manual prove-out process.
- By taking the prove-out process offline, using g-code driven NC verification, simulation and optimization software, manufactures can gain the confidence that the first part will be good every time.
The educational and informative conferences run Sept. 8-11, 2014 in the West Building, Level 1. To register for this or any session, visit www.imts.com/education/imtsconference.html.
