First Claim
Patent Images
1. An implantable fluid management device, comprising:
- an elongate catheter having a proximal end, a distal end, and a first inner lumen extending therethrough;
a sensor disposed at a distal portion of the catheter;
at least one wire having a distal end coupled to the sensor and having a proximal end that is adapted to mate to an external component for powering and/or communicating with the sensor, the at least one wire extending along a length of the catheter such that the at least one wire is in fluid isolation from the inner lumen of the catheter, and the at least one wire being separable from a proximal portion of the catheter such that the length of the catheter is selectively adjustable.

Abstract
An implantable fluid management device is provided that includes a catheter having at least one wire running therethrough and coupled to a sensor disposed at a distal portion of the catheter. At least a portion of the wire is removably coupled to the catheter to allow a length of the catheter to be selectively adjusted, thereby providing a trimmable sensing catheter. The device can be used for a variety of medical procedures, but in an exemplary embodiment the device is a ventricular catheter that is used to drain CSF from a patient'"'"'s ventricles.

18. An implantable fluid management device, comprising:
-
an elongate catheter having a proximal end, a distal end, and first and second inner lumens extending therethrough and isolated from one another;
a sensor disposed at a distal portion of the catheter;
at least one wire extending through the second lumen in the catheter and having a distal end coupled to the sensor and a proximal end adapted to mate to an external antenna; and
a slit extending through an outer wall of the catheter into the second lumen along at least a portion of a length thereof such that a portion of the at least one wire can be at least partially removed from the catheter through the slit to allow the length of the catheter to be selectively adjustable. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27)

28. A method for implanting a ventricular catheter, comprising:
-
providing an elongate catheter having a first lumen extending therethrough and including a sensor disposed at distal portion of the catheter, and at least one wire extending from the sensor and coupled to the catheter such that the at least one wire is in fluid isolation from the first lumen, the at least one wire being separable from at least a proximal portion of the catheter such that a length of the catheter is selectively adjustable;
implanting the catheter in a patient'"'"'s ventricles such that a proximal end of the catheter is adapted to be connected to an implantable valve device;
separating a portion of the at least one wire from the catheter; and
cutting the catheter to a desired length at a location where the wire is removed from the catheter. - View Dependent Claims (29, 30, 31, 32, 33, 34, 35)
