20120109190 | DEVICES, SYSTEMS, AND METHODS FOR CLOSING AN APERTURE IN A BODILY TISSUE - Devices, systems, and methods for closing an aperture in a bodily tissue. In at least one exemplary embodiment of an aperture closure device of the present disclosure, the aperture closure device comprises an elongated body extending from a proximal end to a distal end, and a closure portion coupled to the elongated body, the closure portion configured to fit within an aperture of a bodily tissue and comprising a material capable of autoexpansion within said aperture. | 05-03-2012 |
20110313341 | DEVICES, SYSTEMS, AND METHODS FOR ORGAN RETROPERFUSION - Devices, systems, and methods for organ retroperfusion. In at least one embodiment of a method of organ perfusion of the present disclosure, the method comprises the steps of positioning at least part of a first catheter having a cannula within an artery of a patient, the first catheter configured to permit arterial blood to flow therethrough and further configured to permit a portion of the arterial blood to flow through the cannula, positioning at least part of a second catheter within a vein of the patient at or near a target organ, the second catheter configured to receive some or all of the portion of the arterial blood, and connecting the cannula of the first catheter to a portion of the second catheter so that some or all of the portion of the arterial blood flowing through the cannula is provided into the vein to treat a condition or disease of the target organ. | 12-22-2011 |
20110196282 | DEVICES, SYSTEMS, AND METHODS FOR AUTORETROPERFUSION - Devices, systems, and methods for autoretroperfusion. In at least one embodiment of a perfusion system of the present disclosure, the system comprises a first catheter having a proximal end, a distal end, and a first lumen therethrough, the distal end configured for insertion into a luminal organ of a patient, a coupler defining an outlet port and a first port, the coupler configured to engage the proximal end of the first catheter at the outlet port and to receive blood from a blood supply through the first port, a first tube having a proximal end, a distal end, and a lumen therethrough, the distal end of the first tube configured to engage the first port of the coupler and to receive the blood from the blood supply, and a first flow regulator in communication with one or more of the coupler and the first tube, the first flow regulator operable to regulate a flow and/or a pressure of the blood through at least part of the system, wherein the system is configured to permit the blood from the blood supply to flow through the first tube, the coupler, and the first catheter into the patient to treat a patient condition. | 08-11-2011 |
20100185044 | DEVICES AND METHODS FOR ASSISTING HEART FUNCTION - Devices and methods for assisting heart function. In at least one embodiment of a device for assisting heart function, the device comprises at least two electromagnetic plates having an inner surface, a cardiac processor electrically coupled to at least one of the at least two electromagnetic plates, a bladder having an inner chamber, the bladder attached to an inner surface of at least one of the at least two electromagnetic plates, a source of gas in communication with the inner chamber of the bladder, and at least one catheter having a proximal end and a distal end and having a lumen therethrough, the at least one catheter defining at least one aperture positioned therethrough at or near the distal end of the at least one catheter and comprising a pericardial balloon coupled to the at least one catheter at or near the distal end of the at least one catheter, the proximal end of the at least one catheter in communication with the inner chamber of the bladder. | 07-22-2010 |
20100168791 | SYSTEMS AND METHODS FOR CLOSING A HOLE IN CARDIAC TISSUE - Systems and methods for closing a hold in cardiac tissue. In at least one embodiment of a system for closing a hole in cardiac tissue, the system comprises an engagement catheter having a first and second lumen extending therethrough, an elongated wire capable of insertion into the second lumen of the engagement catheter, a plug capable of insertion into the second lumen of the engagement catheter; an elongated shaft capable of insertion into the second lumen of the engagement catheter, wherein the elongated wire is sized for slidable insertion through the lumen of the shaft and the hole of the plug. | 07-01-2010 |
