Devices and methods for performing avascular anastomosis

A system for performing an end-to-side vascular anastomosis, including an anastomosis device, an application instrument and methods for performing a vascular anastomosis. The system is applicable for performing an anastomosis between a vascular graft and the ascending aorta in coronary artery bypass surgery, particularly in port-access CABG surgery. A first aspect of the invention includes a vascular anastomosis staple. A first configuration has two parts: an anchor member, forming the attachment with the target vessel wall and a coupling member, forming the attachment with the bypass graft vessel. The anastomosis is completed by inserting the coupling member, with the graft vessel attached, into the anchor member. A second configuration combines the functions of the anchor member and the coupling member into a one-piece anastomosis staple. A second aspect of the invention includes an anastomotic fitting, having an inner flange over which the graft vessel is everted and an outer flange which contacts the exterior surface of the target vessel. A tailored amount of compression applied by the inner and outer flanges grips the target vessel wall and creates a leak-proof seal between the graft vessel and the target vessel. A third aspect of the invention has a flange to which the graft vessel attaches, by everting the graft vessel over the flange, and a plurality of staple-like members which attach the flange and the everted end of the graft vessel to the wall of the target vessel to form the anastomosis

Devices and methods for port-access multivessel coronary artery bypass surgery

Surgical methods and instruments are disclosed for performing port-access or closed-chest coronary artery bypass (CABG) surgery in multivessel coronary artery disease. In contrast to standard open-chest CABG surgery, which requires a median sternotomy or other gross thoracotomy to expose the patient's heart, post-access CABG surgery is performed through small incisions or access ports made through the intercostal spaces between the patient's ribs, resulting in greatly reduced pain and morbidity to the patient. In situ arterial bypass grafts, such as the internal mammary arteries and / or the right gastroepiploic artery, are prepared for grafting by thoracoscopic or laparoscopic takedown techniques. Free grafts, such as a saphenous vein graft or a free arterial graft, can be used to augment the in situ arterial grafts. The graft vessels are anastomosed to the coronary arteries under direct visualization through a cardioscopic microscope inserted through an intercostal access port. Retraction instruments are provided to manipulate the heart within the closed chest of the patient to expose each of the coronary arteries for visualization and anastomosis. Disclosed are a tunneler and an articulated tunneling grasper for rerouting the graft vessels, and a finger-like retractor, a suction cup retractor, a snare retractor and a loop retractor for manipulating the heart. Also disclosed is a port-access topical cooling device for improving myocardial protection during the port-access CABG procedure. An alternate surgical approach using an anterior mediastinotomy is also described.

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.

Aneurysm treatment system and method

An external aneurysm support scaffold is implanted around an exterior surface of an aneurysm and prevents substantial dilation or progression of the AAA. Minimally invasive delivery is used via port-access, i.e. for aortic aneurysms along the back, abdomen, or thorax, to a location externally adjacent the aneurysm, such as via laparascopic delivery. The scaffold is unwound or unfolded in-situ to extend partially (e.g. about 270 degrees) or completely circumferentially around the aneurysm. Unique delivery devices allow for deployment around the aneurysm. Gaps between an array of transverse fingers of the scaffold may accommodate branch vessels extending from the aneurismal vessel, such as aortic perforators. An agent is injected to treat an aneurysm, such as by providing support, cell retention or recruitment, and / or angiogenesis. Living cells are delivered to treat an aneurysm. An adjustable graft polymerizes in-situ to support an aneurysm conformed therewith.

Shape-memory port-access tube

The NaPier tube is a self-expanding port-access tube for insertion into body passages. A NaPier tube is typically used with an endoscope disposed within the lumen of an unactivated tube to enable visual navigation to place the tube in a passage. A NaPier tube comprises a shape-memory element, wall material, and a removable sheath. A tear-away, removable sheath maintains the shape-memory element in a compressed state. Upon placement of the distal end of a NaPier tube in the target location in a passage, the sheath is ruptured and removed through the port and the shape-memory element expands to its memorized geometries. Embodiments of the NaPier tube are adapted by length and memorized dimensions for endotracheal intubation and for port-access procedures, such as endoscopic surgery.
