Hemostasis valve device
Hemostasis valve devices and methods of use are disclosed. The hemostasis valve devices include a body member, a slide member, an introducer member, a valve cap, and a valve member. The body member and slide member can be gripped by a user's finger and thumb, respectively. The slide member can be distally displaced by the user's thumb to distally displace the introducer member through the valve member to open the valve member to allow passage of a medical appliance through the valve member. The introducer member can be selectively locked in a distal position to keep the valve open.

4 . The hemostasis valve device of claim 1 , wherein the thumb tab is disposed circumferentially 180 degrees from the finger grip portion to allow the user to grip the hemostasis valve device between a thumb and a finger.
5 . The hemostasis valve device of claim 1 , wherein the thumb tab is configured to be engaged by a thumb of the user to longitudinally displace the slide member relative to the body.
6 . The hemostasis valve device of claim 1 , wherein the nose portion is configured to penetrate through the valve member when the introducer member is distally displaced by the slide member.
7 . The hemostasis valve device claim 1 , wherein the introducer member is rotatable about a longitudinal axis of the hemostasis valve device.
8 . The hemostasis valve device of claim 1 , wherein the introducer member is distally displaceable by the slide member when the hemostasis valve device is in the actuating state.
9 . The hemostasis valve device of claim 1 , wherein the introducer member is prevented from proximal movement when the hemostasis valve device is in the locked open state.
10 . The hemostasis valve device of claim 1 , wherein the nose portion is disposed through the valve member when the hemostasis valve device is in the locked open state.
11 . The hemostasis valve device of claim 1 , further comprising a fluid fitting coupled to a distal end of the body member and in fluid communication with the body bore.
12 . The hemostasis valve of claim 1 , wherein the thumb tab is disposed distal of a proximal portion of the finger grip portion.
13 . The hemostasis valve of claim 1 , wherein a portion of the thumb tab extends radially outward at a right angle relative to the longitudinal axis of the slide member.
14 . The hemostasis valve of claim 1 , wherein the thumb tab comprises a concave arcuate surface.
15 . A hemostasis valve device, comprising:
a body member comprising:
a body bore extending therethrough;
a side-arm comprising a side-arm bore in communication with the body bore;
a finger grip portion configured to be gripped by a finger of a user; and
a guide rail extending along an exterior surface of the body member and aligned with a longitudinal axis of the body member;
a slide member coupleable to the body member comprising:
a thumb grip portion comprising a thumb tab disposed at a distal end of the thumb grip portion, the thumb grip extending radially outward from a longitudinal axis of the slide member such that the thumb tab is disposed radially outward from the slide member;
a guide slot disposed in an interior surface of the slide member and aligned with the longitudinal axis of the slide member, wherein the slot is configured to slidingly receive the rail;
a cap portion disposed at a proximal end of the slide member; and
an introducer portion extending distally from the cap portion comprising:
an introducer bore passing therethrough;
a nose portion disposed at a distal end; and
a valve cap fixedly coupled to the body member, comprising:
a valve member disposed between the body member and the valve cap and penetrable by the nose portion.
16 . The hemostasis valve device of claim 15 , wherein the thumb grip portion extends parallel to the longitudinal axis of the slide member.
17 . The hemostasis valve device of claim 15 ,
wherein the finger grip portion is disposed distally of and coupled to the side-arm; and
