Abstract
The present disclosure describes a medical device assembly comprising an expandable medical device wrapped with an improved constraining sleeve. The sleeve in accordance with various embodiments of the present disclosure is thin walled and translucent, having reduced edge sharpness. The sleeve in accordance with the present disclosure exhibits resistance to ripping and delamination. Various embodiments of the present disclosure provide methods of making sheet material usable for constraining sleeves from flattened film tubes. Methods for making improved constraining sleeves and medical device assemblies that comprise an improved constraining sleeve are also disclosed herein.
Claims14
A biocompatible sheet material comprising:
- a laminate of at least four bonded layers of expanded polytetrafluoroethylene film including two generally parallel and opposing edges;
- and
- at least two reinforcing fiber embedded between any of the bonded layers, wherein a first one of the at least two reinforcing fibers is disposed along a first one of the two opposing edges and a second one of the reinforcing fibers is disposed along a second one of the opposing edges and parallel to the first one of the at least two reinforcing fibers,
- wherein the sheet material is from about 0.08 mm to about 0.10 mm thick, having a burst strength of 400 psi or greater.
A biocompatible sheet material comprising:
- a laminate of at least four bonded layers of film;
- and
- at least one reinforcing fiber embedded between any of the bonded layers, wherein the at least one reinforcing fiber is embedded between the bonded layers such that at least one of the four bonded layers includes a portion that extends beyond a boundary defined by the at least one reinforcing fiber, the at least one reinforcing fiber being longitudinally oriented along a length of the laminate.
A biocompatible sheet material comprising:
- a laminate of at least four bonded layers of film including two opposing edges and defining a flat sheet;
- and
- at least one reinforcing fiber embedded between any of the bonded layers, wherein the at least one reinforcing fiber is disposed along a first one of the two opposing edges.
