The preferred embodiment of the invention contemplates a device configured to prepare and deploy a resilient sleeve on to a portion of body tissue. The device expands the resilient sleeve, uses a vacuum system to draw the body tissue in to the resilient sleeve, and releases the resilient sleeve from the expanded state so that it captures and constricts the body tissue.

Device to deploy a resilient sleeve to constrict on body tissue

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.
