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.

Core Innovation

A hemostasis valve device includes a body member having a body bore extending therethrough and a side-arm having a side-arm bore in communication with the body bore. The body member further includes a finger grip portion configured to be gripped by a finger of a user and a guide rail extending along an exterior surface and aligned with a longitudinal axis. A valve cap is fixedly coupled to the body member, and a valve member is disposed between the body member and the valve cap, with the valve member being penetrable by an introducer member or introducer portion.

The device includes a slide member coupleable to the body member, where the slide member has a thumb grip portion with a thumb tab and a guide slot disposed in an interior surface aligned with the longitudinal axis and configured to slidingly receive the guide rail. The slide member includes a cap portion at a proximal end with internal, distally directed cap teeth. An introducer member includes an introducer bore, a distal nose portion, and a proximal head portion with external, proximally directed head teeth configured to operably engage the internal, distally directed cap teeth when the device is in an actuating state.

In an actuating state, the valve cap includes an internal guide channel slidingly coupleable with a radially outward guide member on the introducer member, and a resilient member is disposed between the valve cap and the head portion. A lock member is internal and is coupleable with the guide member when the device is in a locked open state, with the nose portion disposed relative to the valve member in the respective states. When the device is returned from the locked/open actuating relationship, the device returns to a closed state to prevent blood leakage and hold the appliance in position.

Claims Coverage

The document provides two independent claims, each defining a hemostasis valve device with state-dependent valve opening and a user-actuated slide and introducer arrangement. Across both independent claims, the core claim language emphasizes a body member with body bore and side-arm bore, a guided slide with a thumb grip portion, and a valve-cap/valve-member assembly that is penetrable by an introducer nose portion, with at least one independent claim further specifying teeth engagement and a locked open state with a lock member.

Overall claim coverage concentrates on a guided, thumb-actuated slide coupled to an introducer that penetrates a valve member, with the first independent claim additionally requiring teeth interaction between cap teeth and head teeth, an internal guide channel, and a lock member to define an actuating state versus a locked open state.
