Abstract:
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 entepng the first opening of the tube can exit the second opening of the tube, and fluid entenng 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.
Abstract:
The invention provides an applicator for forming a hole in a wall of a hollow organ and for connecting a hemostatic connection assembly to the hollow organ, wherein, when the hole is formed in the wall of the hollow organ, a first fluid seal exists between the hemostatic connection assembly and the wall of the hollow organ and a second fluid seal exists between the hemostatic connection assembly and the applicator, thereby minimizing fluid loss from the hollow organ. The invention further provides a hemostatic connection assembly for connecting an inlet conduit to a hollow organ, the hemostatic connection assembly comprising a organ wall connection portion, a cuff portion, an extension portion, and a seal ring portion, wherein, during the process of connecting the inlet conduit to the hollow organ, a first fluid seal exists between the organ wall connection portion and the wall of the hollow organ, and a second fluid seal exists between the hemostatic connection assembly and the inlet conduit, thereby minimizing fluid loss from the hollow organ. A method is also disclosed in which the applicator and hemostatic connection assemblies of the invention are used to connect an inlet conduit to a hollow organ.
Abstract:
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 (300) for positioning the hole forming element, and a retractor element (500). In addition, the applicator includes a sequencing means (600) 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 prevents damage to the internal surface of the organ during the formation of the hole.
Abstract:
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.
Abstract:
A method and system for providing delivery point sequencing consistent with the invention includes assigning the plurality of items dynamic sequence numbers as the plurality of items pass through a sequencing component a first time, the sequencing component component comprising a plurality of partitions. Next the method and system include sorting the plurality of items into the plurality of partitions of the sequencing component as the plurality of items pass through the sequencing component the first time, each partition having a corresponding batch of items. And finally the method and system include sorting the items of each batch by the dynamic sequence numbers as the plurality of items pass through the sequencing component a second time, each of the plurality of partitions sorting only items of its corresponding batch.

Abstract:
The present invention relates to an apparatus and method for securing a connector conduit to a hollow organ. The method comprises forming a hole in a wall of the organ; inserting a connector conduit through the hole in the wall of the organ until a flange element comes into contact with the wall of the organ, the flange element being positioned on the connector conduit; and engaging a retention means with the wall of the organ to prevent movement of the connector conduit relative to the wall of the organ, the retention means being positioned on the connector conduit. Exemplary retaining means include a plurality of retaining pins positioned circumferentially around the connector conduit, a plurality of prongs positioned circumferentially around the connector conduit, a balloon positioned on the connector conduit, a torsion spring positioned on the connector conduit, a spiral spring positioned on the connector conduit, or combinations thereof.
