Abstract
Official abstract text for this publication.
Systems and methods for controllably variable fluid flow are disclosed that provide the ability to modify the effective cross-sectional area of the fluid delivery conduit available for fluid flow. Accordingly, selective control of these configurations allows fluid flow to be regulated as desired while the fluid delivery pressure remains the same. Additional configurations provided herein allow for the selective manipulation of a footprint or therapeutic pattern achievable with the medical device during a single procedure, negating the need for the removal and insertion of multiple devices to achieve the same variations in treatment geometry or characteristics.
First claim
Opening claim text (preview).
What is claimed is: 1. A medical device, comprising: a catheter body defining a distal portion; a fluid delivery conduit located within the catheter body and defining an outlet in the distal portion of the catheter body, and a deformation element within the catheter body, the deformation element being rotatable about the fluid delivery conduit to depress an exterior surface of a portion of the fluid delivery conduit to affect fluid flow therethrough. 2. T…
