A stone or tissue capture device comprises a shaft with a deployable sweeping/containment structure at its distal end. The shaft is adapted to be removably placed over and connected to a conventional endoscope. The combination of the capture device and endoscope can be introduced into the various body lumens to capture, fragment/excise, and remove stones or tissue from the bladder and kidney, stomach, peritoneum, and from lumens such as the ureter, colon, hepatic ducts, airways, or blood vessels.

A medical grasping device is disclosed. The medical grasping device may be configured to retrieve an object from within a body lumen. A medical grasping device assembly, wherein a portion of the medical grasping device is disposed within a lumen of a delivery sheath, and methods of using the medical grasping device assembly are also disclosed.

Vascular treatment and methods include a plurality of self-expanding bulbs and a hypotube including interspersed patterns of longitudinally spaced rows of kerfs. Joints between woven structures and hypotubes include solder. Woven structures include patterns of radiopaque filaments measureable under x-ray. Structures are heat treated to include at least shapes at different temperatures. A catheter includes a hypotube including interspersed patterns of longitudinally spaced rows of kerfs. Heat treating systems include a detachable flange. Laser cutting systems include a fluid flow system.

A selectively bendable remote access gripping tool, includes a jaw portion having a pair of jaws or nets movable relative to each other between clamped and opened positions thereof, a handle portion spaced apart from the jaw portion by a bendable central portion that has a hollow, corrugated member that is bendable, and a cord extending through the hollow bendable member that connects the jaw portion and the handle portion.

A retrieval device may have a contracted state and an expanded state. The retrieval device may include a sheath and at least three support members. Each of the support members may have a first portion with a first cross-sectional shape and a second portion with a second cross-sectional shape different from the first cross-sectional shape. A proximal end fixed of each of the support members may be coupled to the sheath, and a distal end may be movable relative to the sheath. The retrieval device may further include at least three movable members movable relative to the support members. Each movable member may extend through a lumen of one support member of the at least three support members and through a lumen of a different support member of the at least three support members.

A method of retrieving calculus in a living body and relocating the calculus to a different location in the living body involves positioning an elongated member in the living body in which the calculus is located, drawing the calculus in the living body toward the elongated member while the elongated member is positioned in the living body so that the calculus is retained by the elongated member; moving the elongated member so that the elongated member is located at a position in the living body that is different from the position of the elongated member in the living body during the drawing of the calculus toward the elongated member; and releasing the calculus from the elongated member so that the calculus is at a position in the living body different from a location of the calculus in the living body while the calculus is being drawn toward the elongated member.

An implantation catheter for implanting an implant into a human or animal body, comprises a first catheter shaft and a holding element being arranged at a distal end of the first catheter shaft, the holding element being configured for holding and releasing the implant. The holding element comprises a shape memory element.

An implanted device, such as an inferior vena cava filter, that is partially embedded in soft tissue is retrieved by coupling a vibration device to the implanted device. The implanted device is disembedded from the soft tissue at least in part by generating a vibration with a vibration generator, transmitting the vibration along the vibration transmission apparatus to the implanted device, and vibrating the implanted device. The implanted device is then moved away from the embedding site. A medical device assembly includes the vibration generator, the implantable device and the vibration transmission apparatus.

An intravascular emboli capture and retrieval system for intravascular embolism protection and embolism removal or maceration. Guidewire mounted proximally and distally located multiple opening filters are deployed within the vasculature and used to part, divide and macerate embolic debris and to capture such embolic debris within the confines thereof. A deployable flexible preformed memory shaped capture sleeve is alternatively used to collapse one or more filters and embolic debris therein for subsequent proximal withdrawal from the vasculature.

A dual operation grasping forceps for use with an endoscope includes an elongated tube having a control mechanism along a first end, and a grasping section along a second end. The grasping section includes a plurality of resilient wire members each having a loop along a distal end. A cable is positioned through the loops to form a circular or triangular shape snare. The grasping members are independently connected to the control mechanism by a first operating wire, and the cable is independently connected to the control mechanism by a second operating wire. The control mechanism selectively moves the grasping section between a retracted position, an extended position and a closed position.
