APPLICATOR, ASSEMBLY, AND METHOD FOR CONNECTING AN INLET CONDUIT TO A HOLLOW ORGAN
First Claim
1. An applicator for forming a hole in a wall of a hollow organ and for connecting a hemostatic connection assembly to the hollow organ, the applicator comprising:
- a hole forming element adapted to form a hole in the wall of the organ, the hole forming element including a cutting element on a distal end thereof;
a retractor element disposed at least partially within the hole forming element, the retractor element comprising a tip at a distal end thereof adapted to penetrate the wall of the hollow organ, and an expansion element positioned near the distal end, the expansion element having a plurality of expansion states;
a sequencing means for coordinating expansion of the expansion element between the expansion states based on the position of the retractor element relative to the hole forming element; and
a mounting element coupled to the hole forming element, the mounting element being configured to support the hemostatic connection assembly,wherein, when the hole is formed in the wall of the hollow organ, the hemostatic connection assembly is positioned on the mounting element and connected to the hollow organ such that 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.

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.

19. A hemostatic connection assembly for connecting an inlet conduit to a hollow organ, the hemostatic connection assembly comprising:
-
a organ wall connection portion adapted to connect to a wall of a hollow organ; a cuff portion connected to the wall connection portion, the cuff portion being adapted to support the inlet conduit during insertion of the inlet conduit through the wall of the hollow organ; an extension portion connected to the cuff portion, the extension portion being extendible from a compressed state to an extended state; and a seal ring portion connected to the extension portion, the seal ring portion being adapted to connect to a portion of the inlet conduit, 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.

33. A method of connecting an inlet conduit to a hollow organ using a hemostatic connection assembly, the method comprising:
-
positioning the hemostatic connection assembly on the applicator for forming a hole in a wall of a hollow organ such that a fluid seal is formed between the hemostatic connection assembly and the applicator; connecting the hemostatic connection assembly to a wall of the hollow organ such that a fluid seal is formed between the hemostatic connection assembly and the wall of the hollow organ; forming a hole in the wall of the hollow organ using the applicator; withdrawing the applicator from the hole formed in the wall of the hollow organ while maintaining the fluid seal between the hemostatic connection assembly and the applicator; occluding the hemostatic connection assembly to form a fluid seal; detaching the applicator from the hemostatic connection assembly while maintaining the fluid seal formed by the occlusion of the hemostatic connection assembly; inserting an inlet conduit into the hemostatic connection assembly such that a fluid seal is formed between the hemostatic connection assembly and the inlet conduit; removing the occlusion of the hemostatic connection assembly; and inserting the inlet conduit into the hole formed in the wall of the hollow organ. - View Dependent Claims (34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46)
