Abstract: A medical device includes a sheath defining a lumen, and an elongate member movably disposed within the lumen. The elongate member includes a basket having a plurality of legs, at least one leg of the plurality of legs is disposed between adjacent first and second slots defined by the elongate member. A first distal relief feature at a distal end of the first slot is longitudinally offset from a second distal relief feature at a distal end of the second slot.

Abstract: A device with a sampling portion configured to engage, sever, and remove tissue from a body can be used to obtain one or more tissue samples from the body. The device can be used to obtain multiple tissue samples simultantously.

Abstract: 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.

Abstract: 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.

Abstract: Embodiments of the invention are directed to a medical device for extracting material from a patient's body. The device may include a core element including a proximal portion extending substantially longitudinally and a distal portion capable of transforming between a coil configuration and a substantially straight configuration. An outer housing having a distal portion enclosing the distal portion of the core element is capable of attaining the coil and substantially straight configurations of the distal portion of the core element. The distal portions of the outer housing and the core element transform between the coil configuration and the substantially straight configuration when the core element is moved relative to the outer housing.

Abstract: An intravascular filter having centering capabilities and a device for manipulation of the filter within a vessel. The manipulation device includes a grasping member disposed at the distal end of an elongate shaft, wherein the grasping member may be used to engage a portion of the filter.

Abstract: Baskets with atraumatic distal tips allow the capture of material from difficult-to-reach areas of the body, while reducing the risk of tissue damage.

Abstract: A device and related methods of use are provided for the capture and removal of various unwanted objects present within the body's anatomical lumens. In an embodiment of the present disclosure, the device includes a sheath, an elongate member, and a retrieval assembly connected to the elongate member and retractable within and extendable from a lumen of the sheath. The device includes one or more legs releasably connected to a portion of the retrieval assembly in response to movement of the elongate member relative to the sheath.

Abstract: 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.

Abstract: A medical retrieval device, and related method, for removing material, such as calculi, from a patient's body. In one embodiment, the device includes a handle, a sheath, and a retrieval assembly located at the distal end of the retrieval device. The retrieval assembly includes a plurality of legs, each of which includes a lumen for receiving fluid. The legs are made of an expandable material that will allow the legs to inflate when the lumen receives a fluid. In another embodiment, the device includes a core element wound to form a helical coil. The helical coil has a lumen for receiving a fluid. The core element is made of an expandable material that allows it to inflate when the lumen within the helical coil receives a fluid.

Abstract: A medical device, and related method, for manipulating material, such as calculi, within a patient's body includes a handle, a sheath, a retrieval basket, and a retainer coupled to the distal end of the retrieval basket. The retrieval basket includes a plurality of legs, each of which includes an intermediate portion located at the distal end of the retrieval basket. The retainer secures at least the intermediate portion of one of the plurality of legs to the intermediate portion of another of the plurality of legs.
