Methods and apparatus for treating infarcted regions of tissue following acute myocardial infarction
Patent number: 7819856Abstract: Apparatus and methods are provided for treating an infarcted region of myocardium following acute myocardial infarction by reducing the rate of blood flow through infarcted region, and then injecting a solution containing stem cells, endothelial progenitor cells or mediators of stem cell mobilization, migration and attachment into the effected region so that the stem cells become embedded therein and promote tissue regeneration. In a first embodiment, delivery of the stem cells, endothelial progenitor cells or mediators of stem cell mobilization, migration and attachment is accomplished using a catheter that relies upon antegrade flow through the coronary artery and a flow control catheter placed in the coronary sinus. In an alternative embodiment, the delivery catheter delivers the stem cells in a retrograde manner through the coronary sinus, and the delivery catheter further comprises an occlusion balloon for controlling outflow through the coronary sinus ostium.Type: GrantFiled: October 5, 2004Date of Patent: October 26, 2010Assignee: Nexeon Medical Systems, Inc.Inventor: Mark C.

Patent number: 6960189Abstract: The present invention is directed to a proximal catheter assembly that is configured to facilitate aspiration through a catheter lumen. The proximal catheter assembly enables natural aspiration to be achieved within the catheter lumen, for example, using an arterial-venous shunt, and further enables suction-assisted aspiration or infusion to be applied through the catheter lumen. This allows a physician to provide a substantially continuous level of retrograde flow within a vessel during a medical procedure without damaging the vessel wall, while providing the option of suction-assisted aspiration, when necessary, to further influence the level of aspiration within the vessel.Type: GrantFiled: March 29, 2002Date of Patent: November 1, 2005Assignee: Gore Enterprise HoldingsInventors: Mark C.
