Abstract: A first notification of a first action by a user with respect to a first content item may be received by a computer system, the first content item having a first relationship to the user. A second notification of a second notification by the user with respect to a second content item may be received by the computer system. The second content item may have a second relationship to the user, and at least a portion of the second content item may correspond to at least a portion of the first content item. A first property of the first relationship may be managed by the computer system based on the second notification.

Abstract: The device to remove kidney stones is a medical retrieval basket device adapted to provide irrigation and suction to the region of the basket. The device includes a retrieval basket assembly having a sheath, an elongated member extending through the sheath, and a basket assembly coupled to the distal end of the elongated member, in a generally known arrangement. The retrieval basket assembly extends from a handle which provides suction and irrigation to, and through, the retrieval basket assembly. Fittings on the handle connect fluid and suction sources through fluid conduits within the handle to the sheath of the retrieval basket assembly. In one embodiment, the retrieval basket assembly's sheath has an expandable distal end portion that improves the retrieval basket assembly's ability to capture debris from lithotripsy of a stone.
