Bioabsorbable Stent And Method Of Making The Same
US Patent:
5527337, Jun 18, 1996
Filed:
Feb 22, 1994
Appl. No.:
8/200556
Inventors:
Richard S. Stack - Chapel Hill NC
Howard G. Clark - Durham NC
William F. Walker - Holcomb NY

Assignee:
Duke University - Durham NC
International Classification:
A61M 2900
US Classification:
606198
Abstract:
A bioabsorbable stent for placement at the locus of a stenotic portion of a body passage, such as a blood vessel, which is flexible and compliant for safe and effective delivery to the site of the stenotic portion of, for example, a blood vessel, and so as to avoid the disadvantages of chronic implantation, such as arterial rupture or aneurism formation while exposed to the continuous stresses of a beating heart. The stent is formed from a bioabsorbable material and is porous or has apertures defined there through to facilitate tissue ingrowth and encapsulation of the stent. The stent is encapsulated and biodegrades or bioabsorbs within a period of days, weeks or months as desired following encapsulation to thereby minimize the likelihood of embolization or other risks of the dissolved material and to avoid the disadvantages of chronic implantation.
