Innovative implant from Nvision corrects hammertoe and expands product offering to lower extremities
SAN ANTONIO, Texas and THORNTON CLEVELEYS, UK–
The VectorTM Hammertoe Correction System, a bioimplant from Nvision Biomedical Technologies, a medical device and biologics company, has been cleared by the FDA for use in the United States. It is the first foot and ankle implant to be made from the advanced, biocompatible PEEK-OPTIMATM HA Enhanced, a polymer from Invibio Biomaterial SolutionsTM. It is also the first lower extremity (Proximal Interphalangeal Joint Arthrodesis) implant to use Structural Encoding®to enable the unique device identification (UDI) required by the FDA.
From focusing on spinal implants, Nvision is now expanding its product portfolio to lower extremities – with the goal to improve patient quality of life in this segment.
“Hammertoe correction is one of the most common foot and ankle procedures, but we realized there are opportunities to improve outcomes,” said Nvision Senior Vice President of Product Development Tom Zink, in a press release. “We have seen real patient success with our interbody fusion product line using Invibio’s PEEK-OPTIMATM Natural polymer. Now with our Vector Hammertoe Correction System, we are utilizing the PEEK-OPTIMA HA Enhanced material to translate and expand this innovation in foot and ankle surgeries.”
Strong partnership to transfer bone apposition benefits to lower extremity applications
Nvision has developed the Vector Hammertoe Correction System for Proximal Interphalangeal Joint Arthrodesis to offer innovative features, including the potential of early bone on-growth using PEEK OPTIMA HA Enhanced. The implant also gives surgeons the ability to correct hammertoe issues with a 100 percent revisable implant.
Invibio closely partnered with Nvision to develop testing and optimize the manufacturing process, while providing support regarding regulatory requirements for the FDA 510(k) submission to obtain clearance for the new implant.
The Vector Hammertoe Correction System is the first lower extremity implant to incorporate Structural Encoding, a patented technology platform licensed from Watershed Idea Foundry that enables the unique identification of medical devices by means of permanent direct part marking. The technology can embed the entire history of the device, and the data can be read by simple X-ray imaging.
“To date, devices made from PEEK-OPTIMA HA Enhanced have been used exclusively for spinal interventions,” noted John Devine, medical business director for Invibio Biomaterial Solutions, in the release. “Nvision’s Vector system is the first time we’ve seen such a device cleared by the U.S. FDA for other than spinal applications. What we’ve achieved here, with Nvision and Invibio working as project partners, is a solution for a relatively common but curiously challenging problem, the curled up, calcified toe. The result is a very small device, but one that, for many hammertoe patients, could literally shape a better future.”
PEEK-OPTIMA HA Enhanced provides a potential solution for fusion across the joint, a surgeon’s primary goal for hammertoe surgery. It does so because hydroxyapatite (HA) is fully integrated within the matrix of Invibio’s PEEK-OPTIMA Natural. This means the HA is integrated, not coated, and available on all surfaces of a finished device. In combination with a modulus of elasticity closely matching that of actual bone, PEEK-OPTIMA HA Enhanced has the potential to promote bone on-growth and healing. Its radiolucent properties are said to result in artifact-free imaging with the ability to easily monitor the healing process.
Nvision´s new foot and ankle implant enables a standard surgical technique that allows direct drilling and the exact placement of the implant. In doing so, the Vector Hammertoe Correction System is said to offer considerable advantages over a conventional K-wire implant procedure.
For one, it achieves a press fit between the implant and the bone because the cavity is accurately drilled and controlled. The precision instrumentation of the Vector system promotes ease of insertion, further improving the success of the procedure. And the structurally encoded pin, once pressed into position, allows for a greater pull-out force than other PEEK hammertoe implants.
Nvision believes that the small cross-sectional area of the intermediary canal makes PEEK-OPTIMA HA Enhanced, with its potential for promoting osteo-integration on the implant, the perfect material for hammertoe correction. Fusion is expected to be stronger, and the patient should be satisfied with the outcome.
