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.
Claims20
A constriction device that constricts body tissue, the device comprising:
- an elongated sleeve including at least one opened end and being formed from elastic material to receive, when in an expanded condition, body tissue to be constricted and to constrict the 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.
A constriction device that constricts body tissue, the device comprising:
- sleeve means formed of elastic material including at least one opened end of constricting body tissue received therein;
- and
- tear resistance means about the sleeve for precluding propagation of a tear in the sleeve means.
