20100010500 | Apparatus and method for connecting a conduit to a hollow organ - An apparatus and method for connecting a first conduit to the heart without the need for cardiopulmonary bypass. The first conduit may then be attached to a second conduit that has a prosthetic device interposed. The second conduit may then be connected to the aorta. The prosthetic device may be a prosthetic valve or a pump, for example. The apparatus of the present invention includes an implantable connector with first conduit component, a retractor expansion component, a coring component, and a pushing component. The retractor expansion component is slide-ably coupled to the coring component. The retractor expansion component serves to seat against and separate the inside apical wall of the left ventricle so that the coring component may cut cleanly through the myocardium to form a tissue plug without leaving any hanging attachments to the inside walls. By remaining seated against the inside wall, the retractor expansion component follows the tissue plug into the coring component. The surgeon applies force and rotary motion to the pushing component sufficient to cut the tissue plug and implant the prosthetic component. | 01-14-2010 |

20110196408 | Apparatus and method for forming a hole in a hollow organ - The invention relates to an apparatus and method for forming a hole in a wall of a hollow organ. The applicator includes a hole forming element for forming a hole in the wall of the organ, a positioning means for positioning the hole forming element, and a retractor element. In addition, the applicator includes a sequencing means for coordinating the relative movement of the retractor element and the hole forming element in a sequential manner to thereby carry out a procedure for forming a hole in the wall of the hollow organ. The sequencing means may further include a safety latch element operatively coupled to the retracting means and the hole forming element. The safety latch of the invention keeps prevents damage to the internal surface of the organ during the formation of the hole. | 08-11-2011 |
20130218261 | APPARATUS AND METHOD FOR CONNECTING A CONDUIT TO A HOLLOW VESSEL - An applicator for forming a hole in a wall of a hollow vessel and engaging a graft, the applicator comprising: a hole forming element adapted to form a hole in the wall of the vessel, the hole forming element comprising a cutting element adapted to cut a hole in the wall of the vessel and a positioning element adapted to hold the position of the applicator relative to the vessel; and an insertion element adapted to be inserted through the wall of the vessel, the insertion element comprising a retraction element adapted to enter into engagement with a graft. | 08-22-2013 |
