    摘要： A steering mechanism is used as part of a medical device such as a catheter or an endoscope to allow movement of a steerable distal portion of the catheter or endoscope. The mechanism can include a elongate housing adapted to be coupled to the steerable portion of the medical device and an actuation system including an actuator, a first cam, and a second cam. The actuator can move the first cam between a first position and a second position along a first axis (or about a second axis different than the first axis) to move the steerable portion of the medical device along a first plane. The actuator can move the second cam between a first position and a second position along the second axis (or about the first axis) to move the steerable portion of the medical device along a second plane different than the first plane.

    摘要： In some embodiments, an apparatus includes a handle and an elongate member coupled to the handle. The elongate member has a first portion, a second portion and a third portion. The first portion of the elongate member extends from the handle and defines a first longitudinal axis. The second portion of the elongate member extends from the first portion and defines a second longitudinal axis. The first longitudinal axis and the second longitudinal axis define a first angle and a first plane. The third portion of the elongate member extends from the second portion of the elongate member and defines a third longitudinal axis. The third longitudinal axis and the second longitudinal axis define a second angle and a second plane. The second plane is non-parallel with the first plane.

    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.
