Abstract: A surgical stabilizer for use with a surgical site retractor has a base, a bendable arm, and a distal cuff adapted to resiliently hold a tube of an elongated port-access device. The cuff may have a body defining a partial enclosure within which is held a highly flexible gasket having a slit for resiliently receiving the tube. The surgical site retractor may have a collapsible ring and a flexible outer portion attached thereto, the ring being sized to pass through an intercostal incision and expand therein under adjacent ribs to prevent removal, and the flexible outer portion extending out of the incision and drawing over the stabilizer base to mutually secure the retractor and base. The port-access tube may be for a heart valve delivery system using an elongated port-access device for transapically delivering a prosthetic heart valve to the aortic valve annulus. A method involves partly installing the surgical site retractor, anchoring the base of the stabilizer with the flexible outer portion, deploying the port-access tube from outside the body through the incision and through a puncture in the heart wall, and resiliently capturing a tube of the port-access within the partial enclosure of the stabilizer cuff. A second bendable arm on the base having a clip may be used to hold still a proximal end of the port-access device.

Abstract: A surgical apparatus and methods for severing and welding tissue, in particular blood vessels. The apparatus includes an elongated shaft having a pair of relatively movable jaws at a distal end thereof. A first heating element on one of the jaws is adapted to heat up to a first temperature and form a welded region within the tissue, while a second heating element on one of the jaws is adapted to heat up to a second temperature and sever the tissue within the welded region. The first and second heating elements may be provided on the same or opposite jaws. A control handle provided on the proximal end of the elongated shaft includes controls for opening and closing the jaws, and may include an actuator for sending current through the first and second heating elements. The first and second heating elements may be electrically connected in series, and the first heating element may be bifurcated such that it conducts about one half of the current as the second heating element. A force-limiting mechanism provided either within the control handle, in the elongated shaft, or at the jaws limits the pressure applied to the tissue by the jaws to ensure that the tissue is severed and the ends effectively welded within a short amount of time.

Abstract: A surgical instrument includes a mount body, a joint member, an arm, and a working end. The mount body has a top portion, a distal end, a proximal end and a bottom portion. The joint member is pivotally mounted at a distal end portion of the mount body, to allow positioning of a proximal portion of an arm extending distally from the joint member. The joint member is also configured to at least partially constrain movement of the proximal portion of the arm to a plane. The working end is mounted to a distal end portion of the arm. The surgical instrument can be configured as a heart stabilizer or a heart positioner. The joint member may further be configured as a slotted ball, a disk member, or a combination thereof.

Abstract: A delivery system for delivering a prosthetic heart valve to the aortic valve annulus. The system includes a delivery catheter having a steering mechanism thereon for delivering a balloon-expandable prosthetic heart valve to the aortic annulus in an antegrade fashion through an introducer passing into the left ventricle through its apex. The introducer may have a more floppy distal section than a proximal section to reduce trauma to the heart wall. The delivery catheter includes a deflecting segment just proximal to a distal balloon to facilitate positioning of the prosthetic heart valve in the proper orientation within the annulus. A trigger in a catheter handle may be coupled to a deflection wire that actuates the deflecting segment, while a slider in the handle controls retraction of a valve pusher. A pre-dilation valvuloplasty procedure may also be utilized.

The introducer may have a more floppy distal section than a proximal section to reduce trauma to the heart wall while preserving good operating field stability. The delivery catheter includes a deflecting segment just proximal to a distal balloon to facilitate positioning of the prosthetic heart valve in the proper orientation within the aortic annulus. A trigger in a catheter handle may be coupled to a deflection wire that actuates the deflecting segment, while a slider in the handle controls retraction of a valve pusher. The prosthetic heart valve may be installed over the existing calcified leaflets, and a pre-dilation valvuloplasty procedure may also be utilized.
