Prosthetic device and method of manufacturing the same

摘要

A knitted prosthetic device has at least two knitted sections, where each knitted section has at least one row of fiber. The knitted prosthetic device also has at least one intra-articular section disposed between the at least two knitted sections. In addition, the at least one intra-articular section has at least one single continuous fiber traversing the at least one intra-articular section and the at least two knitted sections, where the at least one single continuous fiber forms a plurality of traverses extending between the at least two knitted sections. In particular, embodiments may be used as ligament prostheses by anchoring each of the at least two knitted sections to a bone section of a patient. Such embodiments may be constructed from a strong polymer, preferably, but not limited to, silk, where the polymer provides ligament support but bioresorbs as load bearing responsibilities are transferred to tissue resulting from ingrowth.

主权项

1. A method for forming a prosthetic device comprising the steps of:
knitting at least two knitted sections, each knitted section including at least one row of fiber; and forming at least one intra-articular section between the at least two knitted sections, the at least one intra-articular section comprising at least one single continuous fiber traversing the at least one intra-articular section and the at least two knitted sections, and the at least one single continuous fiber forming a plurality of traverses extending between the at least two knitted sections; the continuous yarn traversing the at least one intra-articular section and the at least two knitted sections in a repetitive pattern, extending from the first knitted section to the second knitted section where it pivots to form pivot points where the continuous yarn returns back to the first knitted section; and wherein the pivot points comprise first pivot points disposed at an edge of the first knitted section and second pivot points extending beyond the second knitted section to form side loops which act as extensions for extra-articular anchoring.
