Suture-Anchoring Implanted Medical Devices Engineered From Bioresorbable Metal Alloys

摘要

Herein described are suture-anchoring implanted medical devices formed from a bioresorbable metal alloy that may be used to secure soft tissue to bone. The metallic bioresorbable tissue anchoring devices of the present invention are optimally configured such that all portions of the device are resorbed over a short predetermined period of time while maintaining their tissue anchoring capability and preventing the generation of loose foreign bodies therefrom.

主权项

1. A suture anchoring implant device for affixing a soft tissue graft to a prepared socket in a target boney surface, wherein the device has a generally tubular construction, with a proximal portion and proximal end and a distal portion and distal end, further wherein the device:
(a) has an outer surface provided with a plurality of integral threads characterized by one or more major diameters and one or more minor diameters; (b) has an inner surface defining a central lumen that extends from the proximal to the distal end of the device, wherein the proximal portion of the central lumen is provided with an integral torque-receiving feature that allows the transmission of torque to the device necessary to drive the device into the prepared socket; and (c) is formed from a bioresorbable metallic alloy.
