Adapter for intra-aortic balloons and the like
First Claim
1. An adapter for use with intra-aortic balloon assemblies and the like including a hollow tubular member, the adapter comprising:
- a first resilient, hollow fluid carrying sleeve;
a generally annular-shaped body having a first portion of a first diameter and a second portion integral with said first portion and being of a reduced diameter relative to said first portion;
an elongated bore extending through both the larger and smaller diameter portions of said body and communicating with both end surfaces thereof;
a second resilient, stretchable plastic sleeve having a first portion thereof positioned about the end of the second portion of said body and having an opening adapted to receive an elongated hollow flexible tubular member;
the remaining portion of said second sleeve extending beyond the end of said second portion and adapted to embrace and form a sliding, fluid-tight seal about the tubular member extending through the bore in said body so as to allow the adapter to be slidably positioned at any point along said tubular member while maintaining the integrity of said sliding seal;
said adapter being inserted into said first sleeve; and
an annular groove being provided about the periphery of the first portion of said body to facilitate the tying of a suture about said first sleeve to urge the first sleeve into a fluid-tight seal with said body.

Abstract
An adapter having a first bore which facilitates the insertion and accurate positioning of an intra-aortic balloon, and is designed to fit within a synthetic graft which is sutured, for example, to the femoral artery. An annular groove is provided in the adapter, permitting the graft to be tightly tied thereto in the region of the groove. The silicone rubber blood-tight seal integrally formed with the adapter body, together with the adapter body, allow the catheter to slide freely therein, enabling positioning of the balloon in the aorta after the sutures are tied.
The adapter may further be provided with an additional bore for receiving an arterial pressure line. A separate silicone seal is provided to permit positioning of the pressure line while maintaining the integrity of the seal.
The adapter may be further employed with a Y-shaped cannula having a first arm for connecting blood from a by-pass pump into the aorta and having a second arm for insertion of an intra-aortic balloon assembly, the blood-tight seal being obtained through the use of the adapter.

7. An adapter for use with intra-aortic balloon assemblies and the like, comprising:
-
a generally annular-shaped body having a first portion of a first diameter and a second portion integral with said first portion and being of a reduced diameter relative to said first portion; an elongated bore extending through both the larger and smaller diameter portions of said body and communicating with both end surfaces thereof; a resilient, stretchable plastic sleeve having a first portion thereof positioned about a portion of said body of reduced diameter wherein said opening is adapted to receive an elongated hollow flexible tubular member; the remaining portion of said sleeve extending beyond the end of said second portion and adapted to embrace and form a sliding, fluid-tight seal about the tubular member extending through the bore in said body so as to allow the adapter to be slidably positioned at any point along said tubular member while maintaining the integrity of said sliding seal; an annular groove being provided about the periphery of the first portion of said body to facilitate the tying of a tubular member about said body, into which tubular member the body may be inserted; a second elongated bore arranged in substantially spaced parallel fashion relative to said first bore and extending only through the portion of the body of enlarged diameter; said body portion of enlarged diameter having a slot arranged transverse to said second bore; a resilient sealing member positioned within said slot so as to normally seal said opening, and being puncturable by a needle or the like for selectively unsealing said opening. - View Dependent Claims (8)
