摘要:
An apparatus and method for connecting a first conduit to the heart without cardiopulmonary bypass. The first conduit may be attached to a second conduit having a prosthetic device interposed. The second conduit may then be connected to the aorta. The prosthetic device may be a prosthetic valve (or pump). The apparatus includes an implantable connector with first conduit component, a coring component, a retractor expansion component slidably coupled to the coring component, and a pushing component. The retractor expansion component seats against and separates the inside wall of the left ventricle so that the coring component cuts cleanly through the myocardium, forming a tissue plug. 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.

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.

摘要:
A connector for joining a first hollow structure to the side wall of a second hollow structure, the connector comprising: a fluid-constraining tube having a fluid-constraining neck extending therefrom, wherein the tube comprises a lumen having a first opening and a second opening and the neck comprises a lumen having a first opening and a second opening, the neck being joined to the tube so that the neck is in fluid communication with the tube intermediate the length of the tube, such that fluid entering the first opening of the tube can exit the second opening of the tube, and fluid entering the first opening of the neck can exit the second opening of the tube; at least the portions of the tube adjacent to the first opening of the tube and the second opening of the tube being biased radially outwardly so that they normally assume a radially-expanded configuration, but being capable of being restrained in a radially-contracted configuration, wherein the tube is sized so that, when it is in its radially-expanded configuration, it has an outer diameter which is larger than the inner diameter of the second hollow structure.

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.

The present invention provides a system and method for forming a side branch on a hollow vessel, such as the aorta. The side branch is preferably adapted to be connected to a connector conduit, but any other suitable use is also acceptable. The system comprises a graft including a side branch portion, and an applicator comprising a hole forming element adapted to form a hole in the wall of 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 the graft. The hole forming element may comprise 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. The system further comprises a graft protection element adapted to prevent the graft from being damaged by the cutting element. In this case, the clamping element and the graft protection element may be the same element, for example, an expansion element, which may be expandable from an unexpanded state to fully expanded state and to a partially expanded state. The expansion element may be a balloon, which may be in the shape of a circular toroid, and may include a tension member that restricts the dimensions of the balloon. In addition, the expansion element may be an umbrella mechanism.

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 be connected to the aorta prior to the first conduit being attached to the heart. 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 slideably 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.
