Abstract
A resector balloon system is disclosed generally comprising a catheter with at least one balloon having an outer wall with a resecting, non-slip surface for resecting unwanted biological material, such as tissues or tumors, and a pump that supplies fluid thereto in pulsed fashion to repeatedly deflate and inflate said balloon. In certain embodiments, the pump includes a processor that controls the pulsed supply of fluid based on an established frequency or change in volume. In some embodiments, the system includes a keyed connector with which the pump identifies the balloon type, and in some cases, the system calculates intra-lumen diameters and densities. In some embodiments, the balloon portion of the catheter includes multiple balloon segments, which in some cases, are inflatable separately from one another.
