Patent number: 7849860Abstract: Methods and apparatus for direct coronary revascularization wherein a transmyocardial passageway is formed between a chamber of the heart and a coronary blood vessel to permit blood to flow therebetween. In some embodiments, the transmyocardial passageway is formed between a chamber of the heart and a coronary vein. The invention includes unstented transmyocardial passageways, as well as transmyocardial passageways wherein protrusive stent devices extend from the transmyocardial passageway into an adjacent coronary vessel or chamber of the heart. The apparatus of the present invention include protrusive stent devices for stenting of transmyocardial passageways, intraluminal valving devices for valving of transmyocardial passageways, intracardiac valving devices for valving of transmyocardial passageways, endogenous tissue valves for valving of transmyocardial passageways, and ancillary apparatus for use in conjunction therewith.Type: GrantFiled: January 30, 2006Date of Patent: December 14, 2010Assignee: Medtronic Vascular, Inc.Inventors: Joshua Makower, J.

Patent number: 7134438Abstract: Methods, devices, and systems for a) revascularization and/or b) performing other medical procedures at vascular or non-vascular intracorporeal locations within a mammalian body. The methods generally comprise the formation of at least one extravascular passageway from a blood vessel to a vascular or non-vascular target location. In the revascularization methods the extravascular passageway is utilized for blood flow. In the medical procedure methods the extravascular passageway is utilized as a conduit for accessing or performing procedures at the vascular or non-vascular target location. Also disclosed are catheter devices and systems which are useable to form the extravascular passageways of the invention, as well as apparatus for modifying, maintaining and/or closing such extravascular passageways.Type: GrantFiled: April 29, 2003Date of Patent: November 14, 2006Assignee: Medtronic Vascular, Inc.Inventors: Joshua Makower, J.

Publication number: 20040088042Abstract: Implantable connector devices which are useable to maintain fluidic connection between, or approximation of, openings formed in adjacent natural or prosthetic anatomical conduits (or adjacent openings formed in a single anatomical conduits). These connector devices generally comprise a plurality of radially expandable annular members having one or more elongate strut members extending therebetween. Initially, the device is mountable on or within a delivery catheter while in a radially compact configuration. After the delivery catheter has been inserted into the body, the device is caused to transition to a radially expanded configuration whereby it becomed implanted within the body so as to maintain the desired fluidic connection between, or the desired approximation of, the anatomical conduit(s).Type: ApplicationFiled: October 27, 2003Publication date: May 6, 2004Applicant: TransVascular, Inc.Inventors: Steven Kim, J.
