Catheter based sensing for intraluminal procedures
First Claim
1. A catheter comprising:
- an elongated body having a distal end adapted for insertion into a body lumen and a proximal end opposite the distal end with a working lumen extending therethrough;
at least one sensor disposed on the elongated body generating a signal corresponding to a physiological condition; and
a transmission element adapted to convey the signal between the at least one sensor and an external controller.

Abstract
A system for embolotherapy comprises a catheter with a lumen extending therethrough from a proximal opening to a distal opening through which an embolic agent may be dispensed to a treatment site and at least one sensor coupled proximate to the distal end of the catheter to generate signals relating to a physiological condition in an area of the lumen adjacent to the sensor in combination with a controller receiving and processing the signals to generate data indicative of the physiological condition. A method of performing embolotherapy comprises inserting a catheter including at least one sensor mounted thereon into a blood vessel supplying a target tissue mass, the at least one sensor generating signals corresponding to a selected physiological condition in an area of the blood vessel adjacent thereto and processing signals generated by the at least one sensor prior to treatment of the target tissue mass to determine an initial state of the selected physiological condition in combination with treating the target tissue mass by dispensing an embolic agent from a distal end of the catheter, processing, after initiation of the treatment of the target tissue mass, the signals generated by the at least one sensor to determine a current state of the selected physiological condition and comparing the initial and current states to determine whether a desired change in the current physiological condition has been achieved.
