2. A Y-connector for an angioplasty procedure comprising,
a casing having a bore forming a main passageway for a catheter and having a branch passageway intersecting the main passageway, a first seal in said main passageway having a circular opening therethrough, means for adjusting the diameter of said opening to any diameter between about 0.050 inch and zero, and a second elastomeric seal in said main passageway having a fixed circular opening having a diameter in the range of about 0.040 to 0.035 inch, said second seal preventing blood flow by a dilatation catheter inserted in said passageway, said first seal being adapted to close said passageway when a catheter is removed.

6. A Y-connector for an angioplasty procedure comprising,
a casing having a bore forming a main passageway for a catheter and having a branch passageway intersecting said main passageway, a shoulder forming a seat in said main passageway, a compressible O-ring on said seat, a closure at one end of said passageway and threaded on said casing, a spigot on said closure extending into said passageway to compress said O-ring against said seat and to prevent fluid flow between the outside of said spigot and said casing, said spigot adapted, upon screwing down said closure, to close said O-ring, a membrane in said closure spaced from and axially aligned with said O-ring, said membrane having a circular opening about 0.040 inch in diameter to receive and seal a catheter, and detent means between said spigot and passageway to restrict movement of said spigot away from said O-ring and thus to maintain said O-ring always under some compression.
