Surgically implanted electronic devices for use in experimental physiology

Pathological and surgical evaluations of polytetrafluoroethylene implants to correct medial patellar luxations in the canine species

“…The implant was kept small because smaller ones caused less tissue reaction. This has been pointed out by LeVeen and Barberio (27) and by Cholvin (8). The lower half of the implant was shaped to conform to the contour of the medial, distal portion of the femur, just proximal to the medial con dyle.…”

“…LeVeen and Barberio (27) reported that teflon was not absorbed by the tissues, had interfacial tension and was semiflexible. Cholvin (8) found that solid teflon appeared to be less irritating to tissues than silicones, polyethylene and polyvinyl chloride.…”
