Intravascular Cerebral Catheter Device and Method of Use
First Claim
1. A catheter device, comprising:
- an elongate catheter body, comprising a distal end and a proximal end;
at least one lumen extending from the proximal end to the distal end of the elongate catheter body;
a distal sensor device affixed to the elongate catheter body substantially near the distal end and in electrical communication with a controller, wherein the distal sensor device generates a first signal;
a proximal sensor device affixed to the elongate catheter body proximal the distal sensor device and in communication with the controller, wherein the proximal sensor device generates a second signal; and
a fluid delivery device in fluid communication with the at least one lumen and in electrical communication with the controller;
wherein said catheter device is a cerebral catheter device configured to be inserted into cerebral arteries;
wherein the controller is operable to execute instructions to;
compare the first and second signals generated from the distal and proximal sensor devices, andadjust fluid delivery to the at least one lumen from the fluid delivery device, responsive to a change of the first and second signals generated.

Abstract
Cerebral Catheter devices and methods for use are provided. The catheter devices provided may include an anti-thrombotic agent coating on the exterior surface. The catheter devices may include unique tip configurations to allow improved fluid delivery capabilities. Further, the catheter devices may also or alternatively include one or more sensor devices in communication with a controller that allow automatically adjusting the delivery of a therapeutic fluid, for example a vasodilator, in response to the condition sensed by the catheter device, such as increased pressure. Moreover, the catheter devices may also be used in conjunction with blood flow transducers to detect and timely prevent and treatment vasospasms or other conditions. Methods for preventing and treatment vasospasm, neoplasm, or other pathological conditions while prolonged using the catheter device are also provided.
