Abstract
Abstract An improved Y-adapter in which the lumen extending through the side arm is formed along the arc of a circle and smoothly merges into the lumen extending through the central arm, such that a catheter or guide wire can be smoothly inserted through the side arm of the Y-adapter into the central arm and then twisted and manipulated without distortion.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
80 words
A Y-adapter for an angioplasty procedure comprising, a main body having proximal and distal extremities, said main body having a straight passageway formed along a longitudinal axis that extends from the proximal to the distal end thereof, said main body having an arcuate branch passageway generated along a circular arc that is substantially tangent to said longitudinal axis and extends from the proximal toward the distal end thereof such that said arcuate branch passageway smoothly merges into said straight passageway.
Claim 2
Dependent Claim
80 words
A Y-adapter for an angioplasty procedure comprising, a main body having proximal and distal extremities, said main body having a straight passageway formed along a longitudinal axis that extends from the proximal to the distal end thereof, said main body having an arcuate branch passageway generated along a circular arc that is substantially tangent to said longitudinal axis and extends from the proximal toward the distal end thereof such that said arcuate branch passageway smoothly merges into said straight passageway.
Claim 3
Dependent Claim
26 words
The invention as set forth in claim 1 wherein the invention further comprises: said circular arc having a radius of 2.55 plus or minus 0.50 inches.
Claim 4
Dependent Claim
37 words
The invention as set forth in claim 2 wherein the invention further comprises: said straight and arcuate branch passageways being tapered throughout their lengths such that their cross section decreases from the proximal to the distal ends.
Claim 5
Dependent Claim
31 words
The invention as set forth in claim 2 wherein the invention further comprises: a male luer swivel fitting mounted on the main body at the distal end of the straight passageway.
Claim 6
Dependent Claim
33 words
The invention as set forth in claim 4 wherein the invention further comprises: an o-ring made of elastomeric material providing a hemostatic seal between said male luer swivel fitting and the main body.
Claim 7
Dependent Claim
31 words
The invention as set forth in claim 2 wherein the invention further comprises: a female luer fitting formed on said main body at the proximal end of the arcuate branch passageway.
Claim 8
Dependent Claim
30 words
The invention as set forth in claim 1 wherein the invention further comprises: a hemo stasis valve secured to the main body at the proximal end of the straight passageway.
Claim 9
Dependent Claim
77 words
The invention as set forth in claim 7 wherein the invention further comprises: said hemo stasis valve including a hemo stasis seal made of an elastomeric material, said hemo stasis seal having a generally tubular shape with an axially extending lumen and having a plurality of spiral ribs that extend outwardly from its outer surface such that when the hemo stasis seal is compressed in its longitudinal direction the cross section of the axially extending lumen decreases.
Claim 10
Dependent Claim
37 words
The invention as set forth in claim 7 wherein the invention further comprises: said straight and arcuate branch passageways being tapered throughout their lengths such that their cross section decreases from the proximal to the distal ends.
Claim 11
Dependent Claim
37 words
The invention as set forth in claim 1 wherein the invention further comprises: said straight and arcuate branch passageways being tapered throughout their lengths such that their cross section decreases from the proximal to the distal ends.
Claim 12
Dependent Claim
31 words
The invention as set forth in claim 1 wherein the invention further comprises: a male luer swivel fitting mounted on the main body at the distal end of the straight passageway.
Claim 13
Dependent Claim
33 words
The invention as set forth in claim 11 wherein the invention further comprises: an o-ring made of elastomeric material providing a hemostatic seal between said male luer swivel fitting and the main body.
Claim 14
Dependent Claim
31 words
The invention as set forth in claim 1 wherein the invention further comprises: a female luer fitting formed on said main body at the proximal end of the arcuate branch passageway.
