Abstract
A porous, tubular synthetic prosthesis, prosthesis precursor, and methods of producing the same are provided. Specifically the method involves co-spraying both a water soluble and water insoluble fibrous component onto a mold to form the prosthesis precursor. The water soluble fibrous component may then be at least partially removed so as to provide a porous, tubular synthetic prosthesis.
Claims22
A method of making a porous, tubular, synthetic prosthesis, comprising the steps of:
- (a) electrostatically co-spraying ingredients comprising a water soluble fibrous component and a water insoluble fibrous component onto a mold to form a prosthesis precursor, wherein the water soluble fibrous component functions as a spacer to inhibit coalescence of the water insoluble fibrous component on the mold;
- and
- (b) removing at least a portion of the water soluble fibrous component from the precursor to form the prosthesis, said prosthesis comprising fibrous-shaped voids.
A method of making a tubular prosthesis precursor, comprising the step of co-spraying a water insoluble, fibrous component and a water soluble fibrous component onto a mold to form the tubular prosthesis precursor comprising a water soluble fibrous component and a water insoluble fibrous component.
