摘要： An anastomosis is performed using a flexible mounting structure mounted on the outside of at least one vessel. Fasteners extend through the vessel and are bent towards the incision to attach the flexible mounting structure to the vessel in a manner that controls the edge of the vessel adjacent to the incision. The mounting structures are oriented on each vessel so fasteners on one mounting structure interdigitate with fasteners on the other mounting structure at the location of contact between the vessels when the two vessels are brought together. This creates two complementary sinusoidal-shaped vessel edges with peaks of one edge being accommodated in the valleys of the other edge. The peak-to-valley orientation forms a sinusoidal-shaped joint which is leak free. The fasteners are spaced so proper pressure is applied to the tissue to promote healing without leaking. Furthermore, the fasteners are sized and shaped to properly engage the tissue and bend in a desired manner. Methods and tools for carrying out the anastomosis according to the invention are also disclosed. Methods for forming the fastener and the tines having the proper characteristics are disclosed. An absorbable ring-shaped stent is also disclosed.

摘要： Creating an anastomosis, or the surgical formation of a passage between two normally distinct vessels or lumens, is enhanced by an applier that introduces a ring device without the need for a separate anvil to form a hollow rivet shaped attachment. Moreover, the ring device may be advantageously formed in a cylindrical shape from molded polymer material or stamped from sheet metal with proximal and distal rings connected by proximal and distal arms that respectively form hinged, ring shaped so appose tissue walls. A center ring or portion sits in the attachment site. The applier causes actuating by moving the rings relative to one another. A latching mechanism locks the rings in the actuating state.

摘要： A surgical punch prevents tissue debris associated with punching a hole in a patient's tissue, such as an aorta during an anastomosis procedure, from reentering the patient's bloodstream. The punch includes elements that move the debris away from the cutting site and then capture that debris inside the instrument. The punch also includes means for aligning the punch with the selected site and for atraumatically holding the tissue prior to cutting. Various means for moving the tissue debris and for trapping the tissue debris in the instrument are also disclosed.

摘要： A system for manipulating a heart during cardiac surgery permits coronary surgery on a beating heart while maintaining cardiac output unabated and uninterrupted. Circumflex coronary artery surgery can be performed using the system. A component of the system engages the heart with a heart positioning device, repositions the heart into a displaced position and maintains it in the displaced position while the heart continues to beat with substantially unabated and uninterrupted cardiac output. One form of the system can be used in minimally invasive surgery.

Various suction cups are described each including at least a first chamber having a flexible rim and configured to engage the surface of the beating heart and a second chamber smaller than the first chamber and fluidly connected therewith.

The second chamber is adapted to fluidly connect the first chamber with a source of suction. The support arm is movable with the suction cup to effect movement of the beating heart after engagement of the suction cup to a surface of the beating heart. A method of manipulating a beating heart to orient the beating heart in a desired position for performing a surgical procedure includes providing a suction cup having a first chamber configured to engage the surface of the beating heart, and a second chamber smaller than the first chamber and fluidly connected with the first chamber, the second chamber being further fluidly connected to a source of suction; contacting a surface of the beating heart with the first chamber; applying suction between the first chamber and the surface of the beating heart, thereby engaging the suction member with the surface of the beating heart; and moving the suction member while maintaining engagement with the surface of the beating heart, thereby moving the beating heart.

摘要： Devices and methods of forming a compliant gastroplasty are presented. In general, fasteners that can reversibly couple are inserted into gastric tissue to form a gastric restriction. When an expanding pressure in the stomach exceeds a certain limit, the coupled fasteners can decouple to accommodate and relieve the excess pressure. Upon subsequent stomach shrinkage, fasteners are brought back into proximity and recouple to reform the gastroplasty. In particular, magnetic fasteners can be inserted into gastric tissue by injecting a solidifying composition into the tissue to form the fasteners. Various devices and methods for forming the gastroplasty are discussed.
