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.

Claims

1. A connector for coupling to a guiding catheter and comprising:

a housing defining a conduit communicating with the interior of said guiding catheter, said 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 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 mutual axial orientation of said first and second housing portions 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 a state other than said closed state against the urging of said spring.

2. A connector for coupling to a guiding catheter according to claim 1 wherein said valve comprises an elastomeric element having at least one slit therethrough.

3. A connector for coupling to a guiding catheter according to claim 1 wherein said connector comprises at least one selectable retainer for selectably retaining said at least one elongate element against sliding motion relative to at least one of said first and second housing portions.

4. A connector for coupling to a guiding catheter according to claim 1 wherein said automatically engageable and manually disengageable valve state governing mechanism is operative for fully closing said valve in a single stage operation of a user.

5. A connector for coupling to a guiding catheter according to claim 1 wherein said automatically engageable and manually disengageable valve state governing mechanism comprises an engagement arm formed on said second housing element and having formed thereon a tooth and a serrated surface associated with said first housing element for engagement with said tooth.

6. A connector for coupling to a guiding catheter and comprising:

a housing defining a conduit communicating with the interior of said guiding catheter, said 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 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 mutual axial orientation of said first and second housing portions and permitting at least one elongate element to extend therethrough, even when said valve is in said closed state; and

a selectable retainer for selectably retaining said at least one elongate element against sliding motion relative to at least one of said first and second housing portions.

7. A connector for coupling to a guiding catheter according to claim 6, wherein said selectable retainer is fixedly mounted onto said first housing portion.

8. A connector for coupling to a guiding catheter according to claim 6, wherein said selectable retainer is fixedly mounted onto said second housing portion.

9. A connector for coupling to a guiding catheter according to claim 6, wherein said selectable retainer includes a manually operable locking mechanism for locking said at least one elongate element thereto.

10. A connector for coupling to a guiding catheter according to claim 6 wherein said valve comprises an elastomeric element having at least one slit therethrough.

11. A connector for coupling to a guiding catheter according to claim 6 wherein said at least one selectable retainer comprises at least one notch.

12. A connector for coupling to a guiding catheter according to claim 6 wherein said at least one selectable retainer comprises at least one slot.

13. A connector for coupling to a guiding catheter according to claim 11 wherein said at least one selectable retainer comprises at least one slot which is rotationally offset from said at least one notch.

14. A connector for coupling to a guiding catheter according to claim 13 wherein said at least one elongate element comprises at least first and second elongate elements, such that said first elongate element is retained in said at least one notch and is maintained separated from said second elongate element which is retained in said at least one slot.
