Abstract
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.
Claims20
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, the thumb grip extending from the slide member to a distal end, the thumb grip extending radially outward from a longitudinal axis of the slide member such that the distal end 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 comprising internal, distally directed cap teeth;
- an introducer member comprising:
- an introducer bore passing therethrough;
- a nose portion disposed at a distal end;
- a head portion disposed at a proximal end and comprising external, proximally directed head teeth configured to operably engage with the internal, distally directed teeth when the hemostasis valve device is in an actuating state;
- and
- a body portion extending between the nose portion and the head portion and comprising a guide member extending radially outward from an exterior surface;
- a valve cap fixedly coupled to the body member, comprising:
- an internal guide channel slidingly coupleable with the guide member when the hemostasis valve device is in the actuating state;
- and
- an internal lock member coupleable with the guide member when the hemostasis valve device is in a locked open state;
- a valve member disposed between the body member and the valve cap and penetrable by the nose portion;
- and
- a resilient member disposed between the valve cap and the head portion.

- 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.
