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： A medical device can be used to entrain biological or foreign material during a medical procedure for the fragmentation of the material. The device also can be used to remove the material safely from the body. The device has a core element with a first portion extending substantially longitudinally and a second portion wound to form at least a helical coil in the shape of cone. A flat wire can substantially wrap the first and second portions of the core element, or a wire can substantially wrap the first portion and a sheath can substantially cover the second portion.

摘要： An apparatus according to an embodiment of the invention includes an elongate body disposable within a body lumen of a patient. An expandable member is coupled to the elongate body. The expandable member has a collapsed configuration and an expanded configuration. The expandable member when in the expanded configuration is configured to substantially prevent distal migration of biological material within the body lumen during a medical procedure being performed in the body lumen using a medical device different than the elongate body. In another embodiment, an apparatus includes an expandable member having a collapsed configuration and an expanded configuration and a membrane is coupled to the expandable member. The membrane is configured and formulated to maintain adequate structural integrity when exposed to laser energy applied during a lithotripsy procedure performed within a body lumen when the expandable member is disposed within the body lumen.

摘要： A medical retrieval device includes a basket formed of two or more loops. The basket may be used to retrieve material (e.g., a urinary stone) from a body. The basket opens and closes for end-encapsulation of a stone and is strengthened by support members that interconnect the basket loops. A captured stone may be from the basket with the basket still in the body by opening the loops.

摘要： A medical device includes an elongated member and a reinforced retention structure. The device can be used for draining substances from organs or abscessed areas within a body of a patient. The elongated member is made of a flexible material. The reinforced retention structure extends from or is formed integrally with the elongated member and comprises an elastic member and the flexible material. The reinforced retention structure provides retention strength while providing flexibility and patient comfort. The use of the reinforced retention structure also provides increased stability to the device within the patient's body and combats migration and/or expulsion of the device. The nature of the reinforcement in the retention structure may extend into the elongated member, which allows for larger drainage openings in the device and increases the radiopacity of the device.

摘要： An ablation probe and method of manufacturing the ablation probe are provided. The probe comprises a probe shaft and a unibody electrode element. The unibody electrode element comprises a common electrode base located at the distal end of the shaft, and a plurality of electrode tines distally extending from the electrode base. The electrode element may be created by forming divisions (such as slits or slots) from a first end of an electrically conductive elongate member towards an opposing second end of the elongate member. Alternatively, the divisions can be formed from a first end of an electrically conductive sheet towards an opposing second end of the sheet, and then bent or rolled to form the elongate member. In either case, the common electrode base can either be separately mounted to a probe shaft, or the probe shaft can be formed from the elongate member, in which case, the electrode base will be integrated with the probe shaft as a unibody structure. The electrode tines can be optionally shaped, e.g., to proximally evert.
