Abstract
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 Analysis
Total Claims: 4
Claim 1
Independent Claim
52 words
A compression gasket for a Y-connector comprising: a. a geometrically configured cylinder including a top edge and a bottom edge; b. an hour glass configured outer circumference; c. opposing ribs extending between said edges and engaging said hour glass configured outer circumference; and, d. a rim extending inwardly from an inner circumference.
Claim 2
Dependent Claim
52 words
A compression gasket for a Y-connector comprising: a. a geometrically configured cylinder including a top edge and a bottom edge; b. an hour glass configured outer circumference; c. opposing ribs extending between said edges and engaging said hour glass configured outer circumference; and, d. a rim extending inwardly from an inner circumference.
Claim 3
Dependent Claim
162 words
A compression gasket for a Y-connector, comprising: a. a cylindrical gasket body having a proximal and, a distal end, and a longitudinal inner bore therein, the outer diameters of said proximal end and of said distal end being substantially equal, said longitudinal inner bore collapsing on itself when said gasket is in a non-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, said proximal end and said distal end each having an annular cavity formed by a raised annular ring; and, b. a plurality of ribs for supporting said proximal end and said distal end at said first and second outer circumferential tapered portions.
