Claims
- 1. A method of manufacturing an implant, device or part thereof, wherein at least one elongated blank, formed by a biodegradable polymer matrix and biodegradable reinforcement elements, is wound at least partially, at least once, around a winding center into a helical configuration which forms at least part of said implant, device or part thereof.
- 2. A method according to claim 1, wherein
- the elongated blank is made of a biodegradable polymer or copolymer which is manipulated in at least one manner selected from the group consisting of: orienting, fibrillating and ultra-orienting, by at least one process selected from the group consisting of: mechanical drawing and rapid cooling of a flowing melt,
- and wherein said elongated blank is wound into said helical configuration by working it using at least one manner selected from the group consisting of: applying an external force, applying pressure and applying heat.
- 3. A method according to claim 1, wherein said at least one blank comprises a plurality of blanks which are wound simultaneously around said winding center.
- 4. A method according to claim 3, wherein during winding, said blanks are driven over and under each other to produce a tubular braid.
- 5. A method according to claim 1, wherein said helical configuration comprises a plurality of windings of said elongated blank and wherein said blank is wound around said winding center such that there exists a space free of said biodegradable material between at least some of said windings.
