Abstract
Abstract A constriction device that constricts body tissue and is formed of relatively thin elastic material includes a tear resistance structure to preclude an inadvertent tear in the device from propagating through the device. The tear resistance structure includes a plurality of intersecting ribs formed in the elastic material. The ribs circumscribe the device and define rectangular, square, diamond, wavy, or knurled patterns.

Claims Analysis
Total Claims: 28
Claim 1
Independent Claim
71 words
A constriction device that constricts internal body tissue, the device comprising: an implantable elongated sleeve including at least one opened end and being formed from elastic material to receive, when in an expanded condition, the internal body tissue to be constricted and to constrict the internal body tissue when released from the expanded condition; and a tear resistance structure about the sleeve that precludes propagation of a tear in the sleeve.
Claim 2
Dependent Claim
71 words
A constriction device that constricts internal body tissue, the device comprising: an implantable elongated sleeve including at least one opened end and being formed from elastic material to receive, when in an expanded condition, the internal body tissue to be constricted and to constrict the internal body tissue when released from the expanded condition; and a tear resistance structure about the sleeve that precludes propagation of a tear in the sleeve.
Claim 3
Dependent Claim
17 words
