An apparatus is provided in one example embodiment and includes a body section having an upper surface, a lower surface, and an inner edge circumferentially arranged around at least a portion of an open area. The apparatus also includes a tool extending from the body section into the open area for holding a graft vessel. The lower surface of the body section opposes a receiving vessel when the tool is positioned to transfer the graft vessel to the receiving vessel, such that the graft vessel is axially accessible through the open area to be attached to the receiving vessel. In more specific embodiments, the body section has first and second opposing ends defining a gap sized to permit the vessel to pass through.

A surgical retractor includes a “swivel” having a string extending from one end and a string extending from the midpoint between the two ends. The swivel is delivered by pushing it out of a tube which is inserted through a small incision between the ribs of the patient. After the swivel is deployed, the tube is removed and the string which is attached to the center of the swivel is pulled to lift the pericardium. When the procedure is complete, the swivel is removed from the patient by pulling the string attached to the end of the swivel. According to one embodiment, the swivel is a cylinder with a blunt conical end. According to another embodiment, the swivel has a sharp end which is covered by a spring loaded collar.

The present invention provides catheter apparatus and catheterization methodology for generating an arteriovenous fistula or a veno-venous fistula on-demand between closely associated blood vessels and at a chosen anatomic site in-vivo. The catheter apparatus is preferably employed in pairs, each catheter of the pair being suitable for percutaneous introduction into and extension through a blood vessel. The catheterization methodology employs the catheter apparatus preferably in conjunction with conventional radiological techniques in order to place, verify, and confirm a proper alignment, orientation, and positioning for the catheters in-vivo prior to activating the perforation means for generating a fistula. The invention permits the generation of arteriovenous fistulae and veno-venous fistulae anatomically anywhere in the vascular system of a patient; nevertheless, the invention is most desirably employed in the peripheral vascular system as exists in the extremities of the body to aid in the treatment of the patient under a variety of different medical ailments and pathologies.

A video security system with intercom activated by means of a doorbell. The video input to a remote camera is automatically presented on the video display of a television receiver upon activation of the doorbell while audio from the intercom's speaker microphone is output through the television receiver's speaker system. Following a predetermined time interval after doorbell actuation, the system automatically turns off. If the television receiver is on when the doorbell is actuated, the system automatically provides video camera and intercom information at the television, reverting to the received television signal mode of operation upon user selection.

Described here are devices for closing one or more tissues, and handles for controlling these devices. Generally, the devices described here comprise a snare loop assembly, wherein the snare loop assembly comprises a snare and a suture loop, and a handle for controlling the snare loop assembly. In some variations the snare loop assembly may comprise a retention member that may releasably connect the suture loop to the snare. In other variations the devices comprise one or more force-reducing suture locks to help prevent the suture loop from inadvertently disengaging from the snare loop assembly. In still other variations, the excess-suture management features. The handles described here may be configured to remove excess suture from a suture loop, and may also be configured to release the suture loop from the snare loop assembly.

The present disclosure provides aortic valve prosthetic devices that are constructed in a non-axisymmetric shape, or are expandable to a non-axisymmetric shape for improved results in the repair of defective aortic valves. The devices can be surgically implanted, or they can be implanted percutaneously through an insertion catheter. The expandable devices can be self-expanding or expanded by an inflatable balloon to a non-axisymmetric cross-section geometry.
摘要:
A method for implanting a cardiac support device (CSD) on a patient's heart. An amount of contrast agent sufficient to cause structures on the heart to be visible upon fluoroscopic or other imaging is introduced into the pericardial space surrounding the heart. The heart and contrast agent are imaged to provide a visual indication of the location of the structures of the heart. The CSD is placed on the heart using the visual indications provided by the imaging.

A heart size measuring tool includes a tubular body, a flexible measuring cord having length indicia, a measuring cord support mechanism movable between retracted and extended states with respect to the body, and an actuating mechanism to move the measuring cord support mechanism. When in the retracted state the measuring cord support mechanism is positioned within the tubular body with the measuring cord in a collapsed position. When the measuring cord support mechanism is in the extended state the measuring cord extends around a portion of a heart to be measured. A scale on the body can be used in connection with the indicia on the measurement cord to provide a reading of the heart size.
