Abstract

This invention provides a new class of medical devices and implants comprising amorphous metal alloys. The medical devices and implants may be temporary or permanent and may comprise other materials as well, such as polymers, ceramics, and conventional crystalline or polycrystalline metal alloys.

Specifically, this invention provides implantable surgical fabrics comprising amorphous metal alloys. The presence of amorphous metal alloys in these fabrics can serve a variety of purposes, including structurally reinforcing the surgical fabric and/or imparting to the fabric the ability to shield against harmful radiation. The fabric may be used inside or outside the body during medical procedures. Further, the implantable surgical fabrics may be woven or non-woven fabrics.

Claims

1. An implantable surgical fabric comprising a non-woven sheet reinforced with an amorphous metal alloy throughout the surgical fabric, wherein the non-woven sheet comprises a plurality of amorphous metal alloy threads.

2. The implantable surgical fabric according to claim 1, wherein the amorphous metal alloy threads include a coating.

3. The implantable surgical fabric according to claim 2, wherein the coating comprises a polymeric material.

4. The implantable surgical fabric according to claim 3, wherein the polymeric material is a resorbable polymer.

5. The implantable surgical fabric according to claim 4, wherein the resorbable polymer comprises an element selected from the group consisting of polyglycolides, polydioxanones, polyhydroxyalkanoates, polylactides, alginates, collagens, chitosans, polyalkylene oxalate, polyanhydrides, poly(glycolide-co-trimethylene carbonate), polyesteramides, and polydepsipeptides.

6. The implantable surgical fabric according to claim 2, wherein the coating comprises a healing promoter.

7. The implantable surgical fabric according to claim 6, wherein the healing promoter is selected from the group consisting of thrombosis inhibitors, fibrinolytic agents, vasodilator substances, anti-inflammatory agents, cell proliferation inhibitors, inhibitors of matrix elaboration, and inhibitors of matrix expression.

8. The implantable surgical fabric according to claim 2, wherein the coating comprises a polymeric material and a healing promoter.

9. The implantable surgical fabric according to claim 1, wherein said amorphous metal alloy comprises an element selected from the group consisting of silicon, boron, and phosphorous.

10. The implantable surgical fabric according to claim 1, wherein said amorphous metal alloy is an iron-based alloy containing Fe, Cr, B, and P.
