Abstract
A medical implant is provided defined as an electrospun hollow-cored porous suture ring. The suture ring is a continuous ring made by rolling up circular sheet of electrospun material, which was electrospun over a cylindrical target. The suture ring, upon implantation, is capable of being absorbed and replaced by natural tissue due to ingrowth of cells and nutrients into pores of the electrospun hollow-cored biodegradable suture ring. The suture ring addresses at least some of the existing problems with suture or sewing rings.
Claims18
A medical implant, comprising:
- an electrospun hollow-cored porous suture ring defining a hollow-core diameter, a wall thickness and an overall ring diameter, wherein the electrospun hollow-cored porous suture ring is a continuous ring being a rolled-up circular sheet of electrospun material rolled up over the longitudinal axis of the circular sheet.
A method of making a medical implant, comprising:
- (a) electrospinning a polymer coating on a cylindrical target forming a cylindrical electrospun sheet, whereby the cylindrical target defines a longitudinal axis;
- (b) rolling up the cylindrical electrospun sheet over the longitudinal axis into a ring;
- and
- (c) removing the rolled-up ring from the cylindrical target resulting in an electrospun hollow-cored suture ring defining a hollow-core diameter, a wall thickness and an overall ring diameter.
A method of making a medical implant, comprising:
- (a) rolling up a first polymer sheet on a cylindrical target;
- (b) rolling up a second polymer sheet on the cylindrical target over the rolled up first polymer sheet;
- and
- (c) dissolving the first polymer sheet from the second polymer sheet resulting in a hollow-cored ring defining a hollow-core diameter, a wall thickness and an overall ring diameter.
