Abstract
A method of delivering a therapeutic and/or diagnostic agent to tissue is provided including the steps of inserting a catheter into a bodily cavity, the catheter having a proximal balloon and a distal balloon, inflating the proximal and distal balloons to create a chamber between the proximal and distal balloons, delivering the therapeutic and/or diagnostic agent to the chamber, measuring fluid pressure in the chamber, measuring at least one fluid dynamic characteristic of a subject, and adjusting the delivery of the therapeutic and/or diagnostic agent based at least in part on the measured volumetric pressure in the chamber and the at least one fluid dynamic characteristic of the subject.
Claims18
A system for delivering a therapeutic and/or diagnostic agent to tissue, comprising:
- a catheter having a delivery port and a lumen through which a therapeutic and/or diagnostic agent is communicated to the delivery port;
- at least one first sensor that measures pressure of the therapeutic and/or diagnostic agent being delivered via said port and generates a signal indicating the pressure;
- a processor that receives the signal from said at least one first sensor;
- and
- at least one second sensor that measures at least one fluid dynamic characteristic of a subject and transmits a signal indicating the at least one fluid dynamic characteristic to said processor;
- wherein said processor adjusts the delivery of the therapeutic and/or diagnostic agent based at least in part on said measured pressure of the agent and said at least one fluid dynamic characteristic of the subject.
A method of delivering a therapeutic and/or diagnostic agent to tissue, comprising the steps of:
- inserting a catheter into a bodily cavity;
- delivering the therapeutic and/or diagnostic agent to tissue via said catheter;
- measuring pressure at which the therapeutic and/or diagnostic agent is delivered to tissue;
- measuring at least one fluid dynamic characteristic of a subject;
- and
- adjusting the delivery of the therapeutic and/or diagnostic agent based at least in part on said measured pressure of the agent and said at least one fluid dynamic characteristic of the subject.
