Abstract
A medical product comprises a biodegradable filament and a non-biodegradeable coating. The biodegradable filament forms a stent body having a first end portion, a middle portion, and a second end portion opposite the first end portion. The middle portion extends between the first and second end portions. The non-biodegradeable coating encapsulates the at least one biodegradable filament along the middle portion of the stent body. The non-biodegradeable coating forms a barrier such that the non-biodegradeable coating prevents degradation of the at least one biodegradable filament along the middle portion. The first and second end portions are uncoated. After implantation, the end portions of the stent may biodegrade. The middle portion will not biodegrade due to its encapsulation by the non-biodegradeable coating.
