Catheter device
First Claim
1. A connector for coupling to a guiding catheter and comprising:
- a housing defining a conduit which is adapted to communicate with the interior of a guiding catheter when said connector is coupled to said guiding catheter, said housing including first and second housing portions which are manually axially displaceable relative to one another thereby to position said first and second housing portions in various relative mutual axial orientations;
a selectably openable normally closed valve associated with said conduit for selectable sealing thereof, said selectably openable valve having an open state, a closed state and at least one partially open state realized by suitable relative axial displacement of said first and second housing portions resulting in suitable relative mutual axial orientation thereof and permitting at least one elongate element to extend therethrough, even when said valve is in said closed state, said selectably openable valve including a spring which urges said valve towards said closed state; and
an automatically engageable and manually disengageable valve state governing mechanism operative for automatically retaining said valve in said open state and in said at least one partially open state against the urging of said spring.

Abstract
There is provided a connector for coupling to a guiding catheter including a housing defining a conduit communicating with the interior of the guiding catheter, the housing including first and second housing portions which are manually positionable in various relative mutual axial orientations, a selectably openable normally closed valve associated with the conduit for selectable sealing thereof, the selectably openable valve having an open state, a closed state and at least one partially open state realized by suitable relative mutual axial orientation of the first and second housing portions and permitting at least one elongate element to extend therethrough, even when the valve is, in the closed state, the selectably openable valve including a spring which urges the valve towards the closed state and an automatically engageable and manually disengageable valve state governing mechanism operative for automatically retaining the valve in, a state other than the closed state against the urging of the spring.

9. A connector for coupling to a guiding catheter and comprising:
-
a housing defining a conduit, which is adapted to communicate with the interior of a guiding catheter when said connector is coupled to said guiding catheter, said housing including first and second housing portions which are manually axially displaceable relative to one another thereby to position said first and second housing portions in various relative mutual axial orientations, at least one of said first and second housing portions having integrally formed therewith at least one notch; and a selectably openable normally closed valve associated with said conduit for selectable sealing thereof, said selectably openable valve having an open state, a closed state and at least one partially open state realized by suitable relative axial displacement of said first and second housing portions resulting in suitable relative mutual axial orientation thereof and permitting at least one elongate element to extend therethrough, even when said valve is in said closed state, wherein said notch is adapted to have said at least one elongate element inserted thereinto by a user and retained therein, thereby to prevent axial movement of said at least one elongate element relative to at least one of said first and second housing portions when said valve is in any of said open state, said closed state and said at least one partially open state. - View Dependent Claims (10, 11, 12, 13)
