First Claim
Patent Images
1. A catheter, comprising:
- a flexible tubular member having a proximal end and a distal end with a lumen extending within the tubular member, the tubular member having an opening adjacent the distal end, the opening extending through the wall of the tubular member; and
a control valve adjacent the opening and operable in association with the opening, the control valve moveable between a first position and a second position;
wherein the control valve comprises a mounting piece, and a gate.

Abstract
A rapid exchange catheter having a control valve spaced proximal the distal tip of the catheter. The control valve directing a guidewire out of the lumen catheter through an opening in the side wall of the catheter while allowing passage of a vaso-occlusive device through the lumen of the catheter while preventing the vaso-occlusive device from exiting through the opening.

3. A catheter, comprising:
-
a flexible tubular member having a proximal end, a distal end, and a lumen extending between the proximal and the distal ends, the tubular member having a guidewire port located proximal to the distal end of the tubular member; and
a guidewire valve disposed on the tubular member proximal to the guidewire port, the guidewire valve directing a guidewire out of the lumen of the tubular member while allowing passage of a device through the lumen of the tubular member and out the distal end of the tubular member. - View Dependent Claims (4, 5, 6, 7, 8, 9, 10)

11. A catheter comprising:
-
a flexible tubular member having a proximal end and a distal end with a lumen extending within the tubular member, the tubular member having an opening adjacent the distal end, the opening extending through the wall of the tubular member; and
a control valve adjacent the opening and operable in association with the opening, the control valve moveable between a first position and a second position;
wherein the control valve comprises a gate secured adjacent to the opening. - View Dependent Claims (12, 13, 14, 15, 16)

17. A catheter, comprising:
-
a flexible tubular member having a proximal end, a distal end, and a lumen extending between the proximal end distal ends, the tubular member having a port located proximal the distal end of the tubular member, the port being in communication with the lumen; and
a valve disposed on the tubular member proximal to the port, the valve operable in association with the port, the valve having a gate that is moveable between a first and second position;
wherein when the gate is in the first position, the gate is capable of directing a guidewire out of the lumen of the tubular member through the port, and when the gate is in the second position, the gate prevents an object within the lumen of the tubular member from escaping through the port. - View Dependent Claims (18, 19, 20, 21)
