摘要： A removable stent for implantation into a lumen in a human body. The stent is made from a soft, flexible fiber having an outer surface. An outer bioabsorbable/degradable coating is applied to the outer surface of the filament causing it to become rigid. The coating softens in vivo through absorption and/or degradation such that the stent is readily passed or removed from the lumen as a softened filament after a pre-determined period of time through normal flow of body fluids passing through the lumen or by manual removal.

摘要： A biodegradable stent for implantation into a lumen in a human body. The stent in one embodiment is made from a biodegradable fiber having an inner core and an outer layer. The outer layer is a blend of two polymer components. The inner core has a first degradation rate, and the outer layer has a second degradation rate. The second degradation rate is slower than the first degradation rate. The fiber softens in vivo such that the stent is readily passed from the lumen as a softened fragment or filament after a pre-determined period of time through normal flow of body fluids passing through the lumen.

摘要： Composite materials formed from biocompatible polymer fibers and biodegradable polymers are disclosed. The heat treatment conditions for the reinforcing fibers are described so that the mechanical properties of the fibers can be retained during composite consolidation process. The processing conditions and set-ups to consolidations are constrained to the temperatures lower than fiber heat treatment temperatures. The reinforcing fibers are restrained under tension so that the minimum relaxation occurs during consolidation process.
