PCT No. PCT/US82/00319 Sec. 371 Date Apr. 26, 1982 Sec. 102(e) Date Apr. 26, 1982 PCT Filed Mar. 12, 1982 PCT Pub. No. WO83/03204 PCT Pub. Date Sep. 29, 1983.An autoinflatable catheter is disclosed which comprises an elongated first catheter tube section forming a main catheter body, a short second catheter tube section forming a catheter tip, a balloon support extending between the posterior end of the catheter tip and the anterior end of the main catheter body and an inflatable balloon surrounding the balloon support. The balloon support comprises a rigid cage having a continuous hollow interior and openings for the flow of liquid through the cage to inflate the balloon. The openings are sufficiently large to not significantly restrict the flow of liquid through the openings and to prevent pooling of liquid in the chamber between the cage and the balloon. |
