20090306763 | LOW PROFILE NON-SYMMETRICAL BARE ALIGNMENT STENTS WITH GRAFT - A stent graft for use in a medical procedure to treat a dissection of a patient's ascending thoracic aorta. The stent graft includes bare alignment stents at least at a proximal end, and often with a stent at both ends, each stent having opposing sets of curved apices, where the curved section of one broader set of apices has a radius of curvature that is greater than the curved section of the other narrower set of apices. The proximal stent is flared in a manner such that its broad apices occupy a larger circumference around the stent than do its narrower apices, where this flared feature provides for anchoring engagement near the aortic root in a manner not interfering with the coronary arteries or the aortic valve. | 12-10-2009 |

The stent-graft may include a tubular graft comprising first and second longitudinally extending sides disposed opposite each other and connected at a tangent line. When the locking member is in a locked position, the locking member restrains a surface of the graft against the cannula. The first diameter reducing member may be slidably connected to a first portion of the graft that is disposed proximate the tangent line and may be slidably connected to a second portion of the graft that is spaced circumferentially away from the tangent line. When the first diameter reducing member is in a restrained position, the second portion of the graft is drawn toward the first portion of the graft and the proximal portion of the stent-graft has a reduced diameter configuration with at least two lobes. | 07-05-2012 |
20130079870 | ENDOLUMINAL PROSTHESIS WITH STEERABLE BRANCH - An endoluminal prosthesis may include a tubular main graft body including a sidewall and proximal and distal ends. A first stent may be positioned near the proximal end of the main graft body. A second stent may be positioned adjacent to and distal of the first stent. An opening in the sidewall may be positioned longitudinally between a peak of the first stent and a valley of the second stent. A tubular branch may be disposed in the opening. The branch may include first and second end openings. The branch may be flexibly orientable between a retrograde configuration in which the first end opening is oriented toward the distal end and the second end opening is oriented toward the proximal end and an antegrade configuration in which the first end opening is oriented toward the proximal end and the second end opening is oriented toward the distal end. | 03-28-2013 |
20130218257 | MEDICAL DEVICE DELIVERY SYSTEM AND DEPLOYMENT METHOD - An aortic stent-graft may include a tubular graft extending from a proximal end to a distal end, the graft comprising a proximal sealing portion and an intermediate portion, wherein a proximal end of the intermediate portion abuts the distal end of the proximal sealing portion. At least one sealing stent may be attached to the proximal sealing portion. A first fenestration window is disposed in the intermediate portion. The first fenestration window has a length determined by the equation L=1.23*D−24 millimeters, where L is the length of the first fenestration window. D is between about 24 millimeters and 45 millimeters. | 08-22-2013 |
20130338787 | SYSTEMS AND METHODS FOR DEPLOYING A PORTION OF A STENT USING AT LEAST ONE COILED MEMBER - The present embodiments provide systems and methods for deploying at least a portion of a stent. In one embodiment, the system comprises a cannula having an outer surface, and at least one coiled member having proximal and distal ends and a plurality of turns disposed therebetween. One of the proximal and distal ends of the coiled member is secured to the outer surface of the cannula, and the other of the proximal and distal ends of the coiled member is unsecured relative to the outer surface of the cannula. A portion of a stent is looped around the unsecured end of the coiled member and disposed within spacing between adjacent turns of the coiled member. Rotation of the cannula subsequently causes the portion of the stent to disengage from the coiled member. | 12-19-2013 |
20140142620 | DEGRADABLE BALLOON DEVICE AND METHOD FOR CLOSURE OF OPENINGS IN A TISSUE WALL - This discloses a device for closure of an opening in a medical patient's subcutaneous tissue wall. The devices disclosed included a catheter having one or more inflatable, bio-degradable balloon and one or more sheets of ECM material loaded on and around said catheter. Upon inflation of the one or more balloons the sheet(s) of ECM material are held against the tissue wall by the balloon(s). Surgical methods using the device are also disclosed. | 05-22-2014 |
20140180287 | TISSUE FUSION SYSTEM, APPARATUS AND METHOD - A system for closing a wound tract after performing a percutaneous procedure is provided. The system includes a closure mechanism having a pair of arm portions that are arranged to adjust between an open and closed position. The closure mechanism includes an electrode that is electrically connected to a power source configured to provide an electrical current or waveform to the electrode. The closure mechanism can be delivered to the wound tract, where the arm portions are adjusted to their open configuration. The arm portions can be moved into engagement with the tissue surrounding the wound tract, where the arm portions can be opened further or closed to reduce the size of the wound tract. The waveform can be applied to the electrode to cauterize the wound, and the closure mechanism can be retracted. | 06-26-2014 |

In one example, the stent comprises at least one distal apex having a bifurcation extending into first and second leg regions. A distal end of the first leg region is positioned to overlap the graft material at a location circumferentially spaced apart from a location at which a distal end of the second leg region overlaps the graft material in the deployed state. | 06-26-2014 |
20140277345 | PROSTHESIS DELIVERY DEVICE - A prosthesis delivery device comprises a proximal end and a distal end, a prosthesis retention section at the proximal end, and a prosthesis retained on the prosthesis retention section.

The cannula handle is rotatable with the inner cannula. Further, a positioner handle is releasably engaged with the cannula handle. Rotation of the inner cannula releases the proximal end of the prosthesis from the delivery device and withdrawal of the sheath from over the prosthesis releases the distal end of the prosthesis from the delivery device. | 09-18-2014 |
