Abstract
A shunt system for telemetrically measuring, regulating and/or adjusting cerebrospinal fluid flow rate, intercranial pressure, intraspinal pressure and/or intraventricular pressure and a method for use. The shunt system includes a shunt assembly, a first catheter and a second catheter that may be implanted using a novel introducer assembly. In addition to regulating fluid pressure and flow rate, the shunt system may also be used to deliver therapeutic compositions.
Claims20
A shunt system comprising:
- a first catheter comprising:
- a first tube body;
- and
- a sensor positioned on the first tube body;
- and
- a shunt assembly configured to be surgically implanted in a bodily cavity and removably attached to the first catheter, wherein the shunt assembly comprises:
- a reservoir;
- a valve assembly that controls fluid flow through the shunt assembly;
- and
- a first controller operatively associated with the valve assembly and sensor;
- and
- a second catheter removably attached to the shunt assembly comprising a second tube body.

A shunt system comprising:
- a shunt assembly configured to be surgically implanted in a bodily cavity, wherein the shunt assembly comprises:
- a valve assembly that controls fluid flow through the shunt assembly, wherein said
- valve assembly comprises a pump capable of forcing fluid out of the shunt assembly;
- a first controller operatively associated with the valve assembly;
- a sensor capable of measuring pressure or flow rate, wherein the sensor is operatively associated with the controller;
- a first signal conditioner operatively associated with the controller;
- and
- a first transponder operatively associated with the first signal conditioner and capable of receiving a signal;
- and
- a reader assembly positioned outside the bodily cavity, wherein the reader assembly comprises:
- a second signal conditioner;
- a second transponder unit operatively associated with the second signal conditioner and capable of transmitting the signal;
- and
- a second controller operatively associated with the second signal conditioner.
11 more elements
An introducer system comprising:
- an introducer adapted to introduce a medical device into a body, wherein the introducer comprises:
- a handle;
- a sleeve attached to a distal end of the handle, wherein the sleeve comprises:
- an introducer channel for receiving the medical instrument;
- and
- a recess positioned on an exterior surface of the sleeve, wherein the recess is substantially parallel to the introducer channel and configured to guide surgical incisions.
