  • Patent number: 8512360
    Abstract: Methods and devices for placing a target vessel in fluid communication with a source of blood and a target vessel. A conduit includes first portion adapted to be placed in fluid communication with a source of blood, such as a heart chamber, and a second portion adapted to be placed in fluid communication with a target vessel having a lumen, such as coronary artery. The first and second conduit portions are transverse to each other such that the conduit is generally T-shaped. The conduit lies on an exterior of the heart between the blood source and the target vessel and is configured to deliver blood in multiple directions into the lumen of the target vessel. For example, in an occluded coronary artery, blood flows both toward and away from the occlusion. The conduit may be flexible, rigid, collapsible or non-collapsible, and may be formed of synthetic vascular graft material, tissue, or a combination of the two.

  • Publication number: 20110184505
    Abstract: Anastomotic components may be attached to hollow bodies or vessels by magnetic or mechanical force to create an anastomosis, form a port in a vessel, or repair a diseased vessel lumen. Anastomoses are created by coupling a first connection to an end of a vessel and then attracting it to a second connector secured to the side wall of another vessel. The connection between the first and second connectors may be solidly magnetic, solely mechanical, or a combination thereof. Also disclosed are methods and devices for treating diseased vessel lumens, for example abdominal aortic aneurysm. A plurality of docking members is attached to the vessel at solicited positions, and then one or more grafts is secured to the docking members in any suitable manner.

  • Publication number: 20080171101
    Abstract: Methods and devices for manufacturing a conduit for placing a target vessel in fluid communication with a source of blood, such as a heart chamber containing blood. The conduit includes first and second portion adapted to be placed in fluid communication with a heart chamber and a target vessel. The conduit lies on the exterior of the myocardium between the blood source and the target vessel and delivers blood in multiple directions within the lumen of the target vessel. The conduit, which may be formed of any suitable synthetic vascular graft material, is generally T-shaped with the leg having two free ends disposed in the target vessel, preferably being secured thereto via a suture-free attachment. The conduit comprises vascular graft material and may be manufactured various ways, such as molding a conduit from any suitable biocompatible material or fabricating a conduit from one or more pieces of vascular graft material.

  • Patent number: 6902556
    Abstract: A method and device for occluding a patient's ascending aorta, maintaining circulation of oxygenated blood in the patient and delivering cardioplegic fluid to arrest the patient's heart. An aortic occlusion catheter has an occluding member for occluding the ascending aorta. The aortic occlusion catheter passes through a cannula. Delivery of oxygenated blood is accomplished through either the cannula of the aortic occlusion catheter. In another aspect of the invention, an arterial cannula having a curved or angled distal portion. An introducer straightens the distal portion for introduction into the patient. In still another aspect of the invention, an open-mesh stabilizer is used to stabilize a discoid occluding member.

  • Patent number: 6808498
    Abstract: A guide member positioned through a coronary vessel and the wall of the heart provides access to a heart chamber. A first end of the guide member is passed through the coronary vessel and the heart wall into the heart chamber, and then is passed back out of the heart chamber. The end of the guide member may then be used to deliver devices into the heart chamber to carry out various medical procedures. A conduit delivery system is coupled to the end of the guide member and is delivered into the heart chamber and then used to place a conduit in the heart wall to communicate the coronary vessel with the heart chamber.

  • Publication number: 20030229363
    Abstract: Methods and devices are provided to facilitate the natural formation of a connection between tissue structures within the body. Certain of the subject methods provide for the formation on an anastomotic site between a graft vessel and a native vessel, such as vessels of the cardiovasculature, peripheral vasculature and neurovasculature, angiogenic, by means of facilitating angiogenic and/or arteriogenic processes at one or more selected points of contact or close proximity between the vessels. The subject devices include a mechanism for positioning or situating one vessel adjacent to another vessel, in situ, wherein a selected portion of each vessel is in contact or in close proximity with the other vessel such that a natural bond is formed between the outer tissue surfaces of the vessels at the point of contact or close proximity followed by the naturally occurring angiogenic and/or arteriogenic processes of the body.
