Abstract

A Y-connector with a compression gasket for compressing about a guidewire or catheter when inserted into an inner chamber of a Y-connector and compressed by a rim of a large knurled knob. When the large knurled knob is twisted with an inward force, the rim engages the gasket with inward compression, causing the center portion of the gasket to expand inwardly, thereby frictionally engaging against a guidewire or catheter. The inner expansion of the gasket is substantially equal about the inner circumference of the gasket, thereby providing a seal between the guidewire catheter and bodily fluids, such as blood. A guidewire clamp is included at the end of a side arm extending from the Y-connector body.

Claims

1. In combination, a Y-connector and a compression gasket, comprising:

a. a Y-connector including a space between an inner rim of a longitudinal lumen and a base of a knurled knob, and means for rotating said Y-connector; and

,

b. a compression gasket in said space and including a geometrically configured cylinder including a top edge, a bottom edge and an inner bore which collapses upon itself when said gasket is in a compressed state and an hour glass configured outer circumference.

2. A Y-connector for medical procedures, comprising:

a. Y-connector body having a lumen adapted to house a guidewire or catheter; and

,

b. a compression gasket for sealingly compressing said guidewire or catheter, said compression gasket comprising a cylindrical gasket body having a proximal end, a distal end, and a longitudinal inner bore therein;

the outer diameters of said proximal end and of said distal end being such as to engage the inner circumferential wall of said Y-connector lumen;

said longitudinal inner bore collapsing on itself when said gasket is in a compressed state;

said proximal end having a first outer circumferential tapered portion tapering inward towards said inner bore;

said distal end having a second outer circumferential tapered portion tapering inward towards said inner bore;

said first and said second outer circumferential tapered portions meeting to form in said gasket a portion of outer diameter less than said outer diameters of said proximal end and said distal end; and

, said proximal end and said distal end each having an annular cavity formed by a raised annular ring.

3. The Y-connector of claim 2 further comprising a adapter body having a concentric tubular extension with an annular lip configured to engage and accommodate said annular cavity in said compression gasket.

4. The Y-connector of claim 2 wherein said Y-connector body further includes at least one side port.
