A gastrectomy device includes an elongated member defining a centerline that extends through proximal and distal ends thereof. A shape modification member coupled to the elongated member is movable relative to the centerline of the elongated member. The shape modification member is movable between a first state, adjacent to the elongated member, and a second state, spaced from the elongated member. The shape modification member conforms to a portion of a patient's stomach in the second state.

Embodiments of medical devices and methods are disclosed. The medical devices typically comprises an elongate member with a proximal region and a distal region. The distal region comprises a flexible portion that is more flexible than the proximal region of the medical device. The flexible region includes gaps in the sidewall of the elongate member. Furthermore, the medical device comprises a rigid energy delivery device at the distal end which is configured to deliver energy to tissue when energy is supplied to the energy delivery device. In some embodiments, the medical device comprises a support spine configured to provide support to the flexible portion of the elongate member.

The disclosure relates to a surgical device comprising a rod having a deformable sleeve at its distal end surrounding the rod, the control element being longitudinally movable for moving the proximal end of the sleeve between a rest position, in which the deformable sleeve has a tubular shape, and an active position, in which the sleeve is deformed by bringing together its distal and proximal ends. The rod is made up of an internal hollow tubular element surrounded by a sheath that can move in translation and rotation relative to the internal hollow tubular element. The distal end of the sleeve is fixed onto a peripheral strip of the internal hollow tubular element and the proximal end of the sleeve is fixed onto a peripheral strip of the sheath.

A system for deploying a stent-graft from the femoral artery into the femoral vein and back into the femoral artery in order to bypass a femoral occlusion comprises a penetration catheter and a guidewire capture and stabilization catheter. The penetration catheter may be advanced contralaterally to a location above the occlusion and the capture and stabilization catheter may be introduced upwardly through the femoral vein. The penetration tool on the penetration catheter is used in multiple steps to deploy guidewires which are then used to deploy the stent-graft in the desired location.

An intravascular catheter device for modifying tissue located within a blood vessel and methods of using the same are provided. An expandable portion is secured to a distal end of a flexible catheter tube and is operable between a first position and a second position where the expandable portion is enlarged. An incising element extends lengthwise along an outer surface of the expandable portion and is configured to create axially extending slits in the tissue when the expandable portion is placed in the second position and moved axially through the blood vessel. An abrasive is provided at the outer surface of the expandable portion for abrading the tissue when the expandable portion is placed in the second position and move axially through the blood vessel.

A hernia repair device including a main body, a plurality of suture needle ports, a plurality of suture needles and a central shaft. The central shaft includes a retractable distal flange disposed at a distal end portion of the central shaft and defines a central channel extending through the main body. The suture needle ports are adjustable between a first configuration in which the suture needle ports are housed entirely within the main body and a second configuration in which the suture needle ports partially extend from the distal end portion of the main body. The suture needles are adjustable between a first configuration in which the suture needles are housed entirely within the suture needle ports and a plurality of second configurations in which the suture needles partially extend from distal end portions of the suture needle ports. A hernia repair mesh is attached to the plurality of suture needles.

A medical device is disclosed that can reduce variations in the degree of cauterization by an energy transfer element, and can suppress generation of thrombus formation, tissue damage, and the like due to the cauterization. The medical device can include an elongated shaft portion, and an expansion body that is provided in a distal portion of the shaft portion and can expand and contract in a radial direction, in which: the expansion body includes a plurality of wire portions that are linked with a shaft portion, and a clamping portion that is formed by at least one wire portion and clamps a biological tissue; the clamping portion includes an energy transfer element that outputs energy, and a back support portion; the back support portion includes a receiving surface that can face the energy transfer element when the expansion body expands; and the receiving surface can be inclined.

An intravascular device is provided having a catheter tube and an expandable portion including a plurality of struts capable of being moved between an open and a closed position. An incising element is provided on at least one of the struts and has a sharpened edge for creating an incision in atherosclerotic material located within a blood vessel when the expandable portion is in the opened position. An embolic protection device may be integrated with some or all of the expandable portion.

A method for impacting a suture anchor into bone comprises providing an implantable suture anchor and providing an impactor device for impacting the suture anchor into the bone. The suture anchor is coupled to a distal portion of the impactor device. Positioning the suture anchor engages the anchor with the bone at an implantation site, and powering the impactor device impacts the suture anchor thereby implanting the suture anchor into the bone. The frequency of impaction is less than 20 KHz. The impactor device is then decoupled from the suture anchor, and the impactor device may be removed from the implantation site.

An anchoring delivery system for use in an intracranial artery is provided including a tethering device having an elongated tether and an anchor coupled to a distal end of the tether. The anchor is deployable from a low profile configuration to a higher profile configuration to fix the distal end of the tether at an anchoring site in an anchoring vessel. The tethering device is configured to be used with a guide-sheath having a lumen configured to receive the tether. Related devices, systems, and methods are also described.
