    Abstract: Apparatus and methods for conveying or transmitting force or energy to a medical end effector coupled to a flexible or rigid shaft are described herein. One variation of such apparatus may be used to manipulate tissue and create a tissue fold and may generally comprise an elongate tubular member having an end effector disposed thereon. The end effector may comprise a tissue engagement member adapted to engage tissue, a first stabilizing member and a second stabilizing member positioned at the tubular member distal end, and a launch tube adapted to pivot about the first stabilizing member. Elements of the end effector may be actuable via various force transmission elements and/or mechanisms. Such force transmission elements preferably are integrated into and/or are actuable via a handle. The force transmission mechanisms may be utilized to actuate and/or transmit force to alternative medical end effectors coupled to flexible or rigid shafts.

    Abstract: A surgical valve includes a housing with a proximal housing portion and a distal housing portion cooperating to define a gel cavity. A seal material is disposed in the gel cavity and includes a gel having flow characteristics and in compressible characteristics. A distal guide tube is provided to facilitate retrograde insertion of a surgical instrument into the seal material. During assembly, pressure is applied by the housing portions to the seal material in order to form a circumferential seal and to close an instrument channel. Manufacture can be facilitated by use of a mandrel for maintaining the structural elements in axial alignment. Complimentary screw threads disposed between the first and second housing portions can be used to pressurize the gel and thereby create a locking force on an inserted instrument. Detented tabs can be provided to facilitate control of this locking force.-

    Abstract: A medical device for viewing inside a body and for retrieving an object from a location within the body, the medical device comprising an endoscope (32) having a tube defining a working channel (36) and a basket (48) engageable with the object. In one embodiment of the invention, the basket (48) does not require a sheath and is disposed through the working channel such that the endoscope operates to contain or activate the sheathless basket. In another embodiment of the invention, a single push wire (66) with a collar (64) at its end is used in place of a sheath to control the opening and closing of the basket. In another embodiment of the invention, a tapered and funnel-shaped sheath (70) surrounding the basket is used to contain or activate the basket. The invention minimizes the basket crossing profile so as to improve fluid flow in the working channel.

    Abstract: A high-flow low-pressure irrigation system (10) for directing a fluid to and recovering the fluid from an area within a body, the irrigation system (10) comprising a sheath (37) and a flexible catheter (20) disposed in the sheath (37). The catheter (20) comprises a plurality of apertures (26) at a distal pigtail portion (28). The fluid is directed through the apertures (26) and recovered through the sheath (37). Renal applications include alkaline irrigation for dissolution of uric acid stones, chemo-dissolution of cystine stones, irrigation with chemotherapy drugs after ureteroscopic tumor management, antibiotic irrigation for severe infection (e.g., fungal and bacterial), and irrigation of thrombotic agents (Alum or direct delivery of Amicar for renal bleeding).
