摘要： The invention relates to a medical retrieval device with a basket that has at least one leg that is frangible (i.e., easily breakable) and/or able to dissociate from at least one other leg upon the application of a predetermined force to the basket. The invention allows an operator to release captured material (e.g., a stone) from the basket when the device is still inserted in the body. In an embodiment, the basket legs associate by a magnetic interaction that can be overcome by applying a predetermined force to the basket. In another embodiment, at least a portion of at least one basket leg is made from, or coated with, a substance that is adhesive or that joins at least two legs together when the substance is solid but which melts, dissolves or weakens upon the application of an electrical, thermal or chemical change. In yet another embodiment, the invention provides a basket with at least two legs that are joined together by a joining member that can break, or from which one or more legs can dissociate, upon the application of a predetermined force. In yet another embodiment, the invention provides a basket with at least two legs that are joined together by a joining member by means of at least one shear pin that can break upon the application of a predetermined force.

摘要： An embodiment of a medical retrieval device includes a sheath having a proximal end and a distal end, a handle at the proximal end of the sheath, and a basket. The basket has a collapsed position when the basket is within the sheath and collapsed and an expanded position when the basket is positioned beyond the distal end of the sheath and expanded. The basket includes a plurality of legs, at least one leg having a frangible portion wherein the at least one leg breaks upon application of a predetermined force to the basket. A distal portion of the plurality of legs may be formed from a single piece of material.

摘要： A medical device includes a sheath having a lumen and an elongate member disposed within the lumen of the sheath. The elongate member is moveable relative to the sheath and includes a retrieval assembly. The retrieval assembly has a collapsed position within the lumen of the sheath and an expanded position when extended beyond a distal end of the sheath. The elongate member defines a lumen configured to receive a laser.

摘要： A stone retrieval suction device facilitates the retention and then relocation and/or removal of objects disposed in a patient's urinary system. The device includes an elongated member for placement in a channel of a flexible ureteroscope. The elongated member defines a suction passageway which extends longitudinally therethrough. The elongated member is flexible enough to bend with the flexible ureteroscope, and it is strong enough to prevent collapse of the suction passageway when suction is provided through the suction passageway by a vacuum source. The elongated member includes a distal portion for contacting and retaining an object when the suction is provided.

摘要： A medical retrieval device has a multi-prong retrieval assembly. The multi-prong retrieval assembly has a first position, in which the retrieval assembly extends from the distal end of the sheath to form an open ended grasping device, and a second position, in which the retrieval assembly extends from the distal end of the sheath to form a substantially close ended basket-type retrieval device. When the retrieval assembly is used as a basket-type retrieval device, the distal ends of the prongs of the retrieval assembly that form the basket are not connected to each other. Thus, captured objects may be released by the operator, or by applying sufficient force to separate one or more of the prongs.

摘要： A dual throw advancer/retractor has a pair of finger rings that can independently advance or retract a medical device into a catheter. The advancer/retractor has a body and a channel wherein each finger ring moves independently in the channel. One end of the medical device is preferably secured to the body and forms a loop within the finger ring such that movement of the finger ring creates an amplified movement in the medical device.
