INVERTED DIVERTICULUM TREATMENT DEVICES

摘要

A device for treating a diverticulum includes a containment device and a bushing. The containment device includes an elongate conduit. The bushing is in the conduit of the containment device. The bushing includes a heat-shrink material. The bushing has a first tubular shape including a first open end and a second open end. At least a portion of the diverticulum in an inverted state is positionable into the first open end. The bushing is configured to transform from the first tubular shape toward a second shape upon heating the heat-shrink material. The second shape includes at least a portion of the bushing radially inward relative to the first tubular shape. The bushing in the second shape is configured to hold the diverticulum in a radially compressed inverted state.

1. A method of treating a diverticulum of a body lumen, the method comprising:
positioning the diverticulum in an inverted state at least partially into a first open end of a bushing in an elongate conduit of a containment device, the bushing including a heat-shrink material; and transforming the bushing from a first tubular shape including the first open end and a second open end toward a second shape, wherein transforming the bushing includes heating the heat-shrink material, the second shape including at least a portion of the bushing radially inward relative to the first tubular shape, wherein, after transforming the bushing, the bushing in the second shape holds the diverticulum in a radially compressed inverted state.
