A medical device includes a clevis, a first blade, a second blade, and a tension member. The first and second blades are rotatably coupled to the clevis. The first blade includes a first coupling portion. The tension member is coupled to the first blade and applies a torque to the first blade to rotate the first blade about the clevis between a first, second, and third orientation. The second blade includes a second coupling portion. The second coupling portion is coupled to the first coupling portion such that A) the second blade remains in a fixed position relative to the clevis when the first blade is between the first and second orientation, and B) rotation of the first retractor blade between the second and third orientation transfers at least a portion of the torque to the second retractor blade causing rotation of the second blade about the clevis.

Medical devices having multiple blades and methods of use

A surgical stapler is provided that includes a first jaw and a second jaw. The first jaw includes a proximal end portion and a distal end portion. The second jaw includes a proximal end portion and a distal end portion. The proximal end portion of the first jaw is pivotally mounted to the proximal end portion of the second jaw. A flexible guide is secured to the distal end portion of the first jaw.

Postioning method for stapler with compliant tip

A neuromodulation catheter is positionable in a blood vessel having a wall for use in delivering therapeutic energy to targets external to the blood vessel. An electrically insulative substrate such as an elongate finger is carried at a distal end of the catheter body. The substrate has a first face carrying a plurality of electrodes, and a second face on an opposite side of the substrate from the first face. The finger is biased such that when expanded within the blood vessel, it forms a spiral configuration with the first face facing outwardly to bias the electrodes in contact with the blood vessel wall.

Intravascular electrode arrays for neuromodulation

A surgical instrument having an elongated shaft having a shaft distal end and a shaft proximal end. An end effector is coupled to the shaft distal end and includes opposed jaws. A housing is included in one of the jaws, the housing having a housing proximal end, a housing distal end, an upper surface, a distal garage having lateral surfaces that extend above the upper surface, and a plurality of staple openings extending through the upper surface. A knife member is supported within the housing for movement distally. The knife member is moveable into a predetermined parked position such that a first portion of the cutting blade displaces below the upper surface and a second portion remains displaced above the upper surface. There is enough lateral clearance in the predetermined parked position between the lateral faces and the second portion to accommodate a dislodged staple.

Surgical staple cartridge with enhanced knife clearance

An intestinal implant includes a proximal anchor self-expandable from a radially compressed position to a radially expandable position for engagement with a wall of the intestinal lumen and a flexible sleeve coupled to the anchor. The sleeve is implanted with the anchor downstream from the pylorus and the sleeve extending further downstream through the intestinal lumen.

Intestinal sleeves and associated deployment systems and methods

An intravascular electrode device for use in neuromodulation includes an anchor expandable from a radially compressed position to a radially expanded position. A lead extends from the anchor and has at least one conductor extending through it. A flex circuit is coupled to the anchor and comprises a flexible insulative substrate, a plurality of electrodes carried by the substrate, and a plurality of conductive traces carried by the substrate, each trace electrically coupled to an electrode and a conductor. Expansion of the anchor within a blood vessel biases the electrodes into contact with the surrounding blood vessel wall. An exemplary anchor includes a first portion having expansion forces sufficient to bias the electrodes against the vessel wall for mapping and chronic stimulation, and a second portion having greater radial expansion forces sufficient to chronically engage the vessel wall once an optimal electrode location has been selected.

Intravascular electrodes and anchoring devices for transvascular stimulation

A system for performing multi-tool minimally invasive medical procedures through a single instrument port into a body cavity includes a rigid tube carried by a mount. Cannulas having instrument channels and steerable distal ends extend distally from the rigid tube. During a procedure using the system, the mount is supported by an operating room fixture, and instruments are advanced through the steerable instrument channels. Manipulation of the instrument handles engages actuators positioned on the mount, which steer the distal ends of the cannulas through the action of pull cables. The distal ends of the instruments may thus be steered within the body by the distal ends of the steerable cannulas.

System and method for multi-instrument surgical access

A woven tubular endoprosthesis comprising means for locking the endoprosthesis in a deployed configuration is disclosed. The means for locking the endoprosthesis may comprise locking protrusions, notches, a chemical bond, a curable bond, or other mechanism. The woven fibers comprising the endoprosthesis may be hollow and comprise circumferentially oriented polymeric chains, and may be filled with a curable material. A method of treatment using an endoprosthesis according to the invention is also disclosed.

Endoprostheses and methods of manufacture

A system for performing multi-tool minimally invasive medical procedures through a single instrument port into a body cavity includes an expandable frame that carries a pair of tool cannulas, each of which has a lumen for receiving a tool useable to perform a procedure in the body cavity. The frame is expandable to orient the tool cannulas such that they allow the tools to be used in concert to carry out a procedure at a common location in the body cavity.

System and method for multi-instrument surgical access using a single access port

Improved polymeric endoprostheses having reinforcement elements and methods of making the endoprostheses are disclosed. The devices disclosed exhibit improved overall compliance, selective regional compliance, and selective radial strength without varying the geometries of selected regions. Numerous other physical characteristics of the endoprostheses described may be selectively varied during manufacture. Some embodiments may include an erodible polymer and magnesium. Some embodiments may have one or more therapeutics incorporated into the endoprosthesis via a solvent in a supercritical state.

Polymeric endoprosthesis and method of manufacture

Methods of manufacture of endoprostheses comprising one or more photocurable materials are disclosed. The endoprostheses may comprise regions wherein the photocurable materials are selectively disposed about the endoprosthesis and are cured according to desired parameters to achieve varying desired properties. Photolithographic masking material may be selectively disposed about an inflatable balloon and exposed to a radiation emitting catheter.
