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.
