1. In a hemostatic catheter including a housing mounted on the catheter, said housing including a self-sealing penetrable barrier, the improvement comprisingan elastomeric partition valve made of one-piece construction;
- said partition valve including first slit means defined by a first side of said valve;
second slit means defined by the opposite side of said partition valve;
each slit means having a location which creates two spaced apart points of intersection with the other slit means;
each slit means having a depth that is insufficient to extend through the entire thickness of said partition valve,whereby sealing is provided to an implement inserted through said partition valve.

Abstract
A hemostasis valve for a catheter or the like may be a self-sealing, penetrable barrier which comprises an elastomeric partition made of an integral piece. A first slit is cut on the first side of the partition, while a second slit is cut in a second, opposite side of the partition. The first and second slits are in intersecting relation to each other, each slit having a depth sufficient to permit physical interaction with each other but insufficient to extend through the entire thickness of the partition.

7. In a hemostatic catheter including a housing mounted on the catheter, said housing including a self-sealing penetrable barrier, the improvement comprising
an elastomeric partition valve in the form of a disc, made of one piece construction; -
said partition valve including first slit means defined by a first side of said valve, said first slit means defining a Y-shape having a pair of angled arms and a leg; second slit means defind by the opposite side of said partition valve, said second slit means defining a Y-shape having a pair of angled arms and a leg; the respective legs of said first slit means and said second slit means pointing in substantially opposite directions, with each arm of each slit intersecting an arm of the other slit whereby two spaced apart points of intersection are created; and each slit means having a depth that is insufficient to extend through the entire thickness of said partition valve.
