    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.

    摘要翻译： 本发明涉及一种具有篮子的医疗检索装置，该篮子具有至少一条腿，所述至少一条腿在施加预定的力到篮子时是易碎的（即容易破裂的）和/或能够与至少一个其他腿分离。 本发明允许操作者当装置仍然插入身体时从篮子释放捕获的材料（例如石头）。 在一个实施例中，篮子腿通过磁性相互作用相关联，该相互作用可以通过对篮子施加预定的力来克服。 在另一个实施例中，至少一个篮腿的至少一部分由物质制成或涂覆有物质，当该物质是固体但在施用时熔化，溶解或弱化的物质是粘合剂或将至少两条腿连接在一起的物质 的电，热或化学变化。 在另一个实施例中，本发明提供了一种具有至少两个腿部的篮子，所述至少两个腿部通过接合构件连接在一起，所述连接构件在施加预定的力时可能会断裂，或者由一个或多个腿部分离。 在另一个实施例中，本发明提供了一种具有至少两个腿部的篮，其通过连接构件通过至少一个剪切销连接在一起，所述剪切销在施加预定力时可能破裂。

    摘要： In one embodiment, an endoscope includes an elongate member having a proximal end portion and a distal end portion. The distal end portion is configured to be inserted into a body lumen. An electrical component is disposed within the distal end portion of the elongate member and configured to produce a signal. An elongate conductive mechanical component has a proximal end portion and a distal and portion. The distal end portion of the elongate conductive mechanical component is electrically coupled to the electrical component and configured to conduct the signal or electrical power from/to the electrical component to/from the proximal end portion of the elongate conductive mechanical component.

    摘要： A method according to an embodiment of the invention includes inserting an endoscope at least partially into a body lumen. At least a portion of the body lumen is illuminated at a first wavelength. The portion of the body lumen is illuminated at a second wavelength different than the first wavelength. A characteristic of an area of interest when the portion of the body lumen is illuminated at the first wavelength is compared with the characteristic of the area of interest when the portion of the body lumen is illuminated at the second wavelength. A medical device or treatment parameter is selected to treat the area of interest based on the comparing. In some embodiments, the body lumen is a ureter. In such an embodiment, a composition of a kidney stone within the ureter can be identified.
