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, wherein the distal sensor device generates a signal that is a distal pressure;
a controller in communication with the distal sensor device, anda 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 configured to store one or more signals collected over time as historical signals corresponding to one or more historical distal pressure measurements and to perform an analysis comprising comparing;
the signal generated from the distal sensor device to the historical signals and determine whether the first signal is greater than or lower than at least one of the historical signals, and cause an(a) increase in fluid delivery to the at least one lumen from the fluid delivery device if the distal pressure is at a first predefined limit greater than at least one of the historical distal pressures, or(b) decrease in fluid delivery to the at least one lumen from the fluid delivery device if the distal pressure is at a second predefined limit lower than at least one of the historical pressures.

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.
