  • Patent number: 8109949
    Abstract: Compression plate apparatus enables vessels to be joined together in various anastomosis configurations. The compression plates are guided to each other in a parallel orientation by guides. The compression plate apparatus may be utilized with an intraluminally directed anvil apparatus or an externally positioned anvil apparatus. One of the compression plates assists in the eversion of the anastomosis fenestra contour. One of the compression plates enables a graft vessel to be pre-everted so that the anastomosis fenestra contours are everted. The apparatus provides a structure that enables the vessels to be joined without being penetrated.

  • Patent number: 7131959
    Abstract: The invention provides vascular access methods, systems and devices facilitating long-term, repeated, percutaneous access to a patient's blood stream. This is provided by an access tube apparatus adapted for anastomosis to the sidewall of a target anatomical vessel. The access tube has a replaceable occluder that fits within the conduit of the access tube in between blood treatments or when vascular access is otherwise not needed. When such access is desired, the percutaneously accessible occluder is simply removed from the access tube.

  • Patent number: 7124570
    Abstract: The invention provides a vascular access system and methods for facilitating long-term, repeated access to any of a patient's vascular systems. This is provided by an access tube apparatus adapted for anastomosis to an anatomical vessel. The access tube is occluded with an fluid occluder that fits within the conduit of the access tube in between treatments or when vascular access is otherwise not needed. When such access is desired, the fluid occluder is withdrawn from the access tube and the body fluid is accessed through the access tube.

  • Publication number: 20040225306
    Abstract: A paired, expandable anastomosis device joins two vessels together and can expand and contract with changes in the size of the two vessels. The anastomosis device has two expandable rings with a plurality of holding tabs. The holding tabs of one ring are shaped to enable a graft vessel tissue to be everted through one of the rings and to be held on one of the rings. Similarly, the holding tabs of the other ring are shaped to enable a target vessel to be everted through the other ring and to be retained by the holding tabs. Once the graft and target vessels are loaded, the rings are adapted to be brought together to a position in which the graft and target vessels are anastomosed together.

  • Patent number: 6743244
    Abstract: The present invention is directed to a cutting apparatus for cutting an opening in a vessel for subsequent anastomosis. The cutting apparatus includes an anvil, an anvil pull and a cutter. The anvil is inserted through a small incision at the anastomosis site and brought into contact with the interior wall of a vessel so that the anvil distends the wall of the vessel. The cutter is then urged against the portion of the vessel wall that is distended by the anvil to form an opening in the vessel wall. The anvil has a surface that is softer than the cutter so that the cutter can cut completely through the vessel and depress into the anvil.

  • Patent number: 6726694
    Abstract: Anastomosis procedures are achieved through the use of an intraluminally directed anvil apparatus. The apparatus is inserted at a catheter site and is then positioned through the lumen of the blood vessel to a remote anastomosis site. The intraluminally directed anvil apparatus has an anvil pull extending from an anvil. At the anastomosis site, the anvil is extended through the wall of the vessel at an initial piercing. The anvil is too large to pass through the initial piercing so the anvil pull can be used to pull the anvil against the wall of the vessel and distend the vessel wall in preparation for being cut to form an opening. The apparatus is used with a cutter to form openings in a wall of a blood vessel. After the opening is formed then the vessel is joined with another vessel.

  • Patent number: 6652542
    Abstract: Anastomosis procedures are achieved through the use of a system adapted for use with an intraluminally directed anvil apparatus having an anvil pull extending from an anvil. The system has an engager for engaging the anvil pull so that a vessel can be distended by the anvil as the anvil pull is pulled. The system has a cutter for forming an opening in a vessel. The system is adapted for use with a compression plate apparatus used to eversion and holding everted surfaces around the opening together. The system can also be used with an externally positioned anvil apparatus.
