Problems solved by technology

Despite the considerable advances that have been realized in cardiology and cardiovascular surgery, heart disease remains the leading cause of death throughout much of the world.
Some of the challenges associated with such procedures include proper positioning of the conduit in the myocardium as well as correct placement of the conduit in a coronary artery.

Embodiment Construction

[0045]Referring to FIGS. 1-4, a device constructed according to one preferred embodiment of the invention is indicated generally by the reference numeral 10. The device 10 is used to place a conduit in fluid communication with a target vessel, the conduit also preferably being placed in fluid communication with a source of blood. As used herein, source of blood refers to any structure containing blood, although a structure containing oxygenated blood, i.e., blood containing some level of oxygen, is preferred. For example, the source of blood may be a heart chamber while the target vessel may be a coronary artery or vein or another vessel.

[0046]The device 10 comprises a handle 12, a shaft assembly 14 and an actuator assembly 16 (FIGS. 2-4). The shaft assembly 14 may be relatively flexible to permit it to bend during use, or it may be substantially rigid. The degree of flexibility imparted to the shaft assembly 14 of the device 10, as well as the dimensions and shape of the device 10,...

Abstract

Methods and devices for placing a conduit in fluid communication with a target vessel and a source of blood, such as the aorta or a heart chamber. The device may be actuated using one hand to place the conduit. The invention allows air in the conduit to be removed prior to placement of the conduit. The invention deploys the conduit in the target vessel by moving a sheath in a distal direction and then in a proximal direction. A conduit is provided with a reinforcing member to prevent kinking of the conduit, and a structure for preventing blockage of the conduit by tissue. A vessel coupling may be used to secure a conduit to a target vessel so as to preserve native blood flow through the vessel, and the conduit may be placed in fluid communication with a target vessel via a laparoscopic or endoscopic procedure.
