摘要： An embodiment of the invention includes a device for collecting body tissue. The device may include an inner member comprising a hollow portion to collect body tissue and a distal end configured to both penetrate body tissue and define an opening of the hollow portion. The device may further include an outer member, co-axially and slidably disposed around the exterior of the inner member, comprising a distal end portion. The distal end portion of the outer member may be configured to penetrate body tissue, prevent body tissue from exiting the hollow portion of the inner member, and allow the distal end of the inner member to extend beyond the distal end of outer member. The opening of the hollow portion of the inner member may be disposed in a plane that is not perpendicular to the longitudinal axis of the inner member.

摘要： A medical retrieval device includes a handle, a sheath, and a basket having basket legs and an atraumatic distal tip. The atraumatic tip of the basket is formed, for example, by entwining the ends of the basket legs together at the distal tip of the basket. Baskets with atraumatic tips according to the invention allow the capture of material from difficult to reach areas of the body while reducing the risk of tissue damage.

摘要： A medical retrieval device includes a basket with three or more legs. The device can be used to retrieve material from a body such as stones. At least one of the legs of the basket is moveable independently from at least one of the other legs. This independent movability allows material to be captured more readily and easily. A distal end of the basket can be non-perforated.

摘要： An embodiment of the invention includes an entry needle. The entry needle may include a cannula, a needle extending within a lumen of the cannula, and a hub operatively associated with a proximal portion of the cannula. The hub may include a branch in communication with the lumen of the cannula. The needle may be movable between a first position and a second position. In the first position, the needle may prevent communication between an opening in an outer wall of the cannula and the branch. In the second position, the needle may allow communication between the opening in the outer wall of the cannula and the branch.

摘要： An endoscopic needle device having a handle and a catheter sheath connected to the handle, wherein the catheter sheath has at least one lumen, for example a needle lumnen and a stabilization lumen, extending there through. A needle is selectively movable within the needle lumen between a needle retracted position and a needle extended position and a stabilization element is selectively movable within the stabilization lumen between a stabilizer retracted position and a stabilizer extended position. A linking mechanism may operatively connect the needle and the stabilization element so that when the needle is in the needle retracted position the stabilization element is in the stabilizer extended position and when the needle is in the needle extended position the stabilization element is in the stabilizer retracted position.
