Catheter introducer system for exploration of body cavities

摘要

A self propelling catheter introducer system for exploring a body cavity is disclosed which includes a flexible tubular catheter, an everting tube and a steering section located near the distal end of the catheter that is introduced in a body cavity. The steering section is adapted for pointing the distal end in a desired direction using a plurality of rods adapted to be extended and retracted.

主权项

1. A self propelling catheter introducer system for exploring a body cavity, comprising:
a flexible catheter having a distal end and a proximal end, wherein the catheter includes a working channel formed within the catheter; a steering section of the catheter disposed adjacent the distal end of the catheter, wherein the steering section includes a steering mechanism coupled to an outer perimeter of the steering section without extending through the working channel of the catheter, the steering mechanism being configured to point the distal end of the catheter in a desired direction; and a propulsion section configured to propel the tubular catheter in the body cavity, the propulsion section including an anchor configured to secure the propulsion section to an opening of the body cavity.
