Abstract
A compassion ring to grip and compress body structure such as diverticulum, hemorrhoids, and tissue adjacent a hole. A resilient ring-shaped body defines a compression channel, and as elongated axially rigid gripping member extends diametrically across the through-opening. The gripping member cm rest on a flange on the opposite side of the through-opening or engage with a second gripping member mat extends diametrically across the through-opening from the opposite side of fee ring. Or, a flexible cage structure can be disposed in the through-opening.
Claims12
Ring for engaging tissue comprising:
- a round body defining an axial through-opening configured to receive the tissue, the through-opening defining an axis;
- and
- at least one gripping member extending within the through-opening, the gripping member having a first end embedded in the ring and a second end distanced from the first end and not embedded in the ring, the gripping member being barbed.
Method for making a tissue gripping ring, comprising:
- forming at least one spike on a circular support, the spike extending inward relative to the circular support;
- overmolding a resilient ring onto the spike;
- and
- removing the spike and ring from the circular support.
Method for configuring a resilient ring for placement in a patient to cause the ring to surroundingly grip tissue in the patient, comprising:
- engaging the ring with a first end of an expander, the expander tapering radially outwardly from the first end to a cylindrical segment, a diameter of the first end substantially equaling a diameter of the ring when the ring is in a relaxed state;
- pushing the ring along the expander to radially stretch the ring until the ring surrounds the cylindrical segment;
- juxtaposing the cylindrical segment with a carrying portion of a delivery device having substantially the same diameter as the cylindrical segment;
- and
- pushing the ring from the cylindrical segment onto the carrying portion to load the ring in a stretched state for delivery to the tissue.
Method for making a tissue gripping ring, comprising:
- forming at least one spike in a conical cage configuration;
- overmolding a resilient ring onto the cage.
