Inflatable cannula
First Claim
1. An expandable lumen cannula, comprising:
- an elongate tubular member having an outer wall, a proximal end, a distal end, and a lumen therebetween, wherein the elongate tubular member is expandable from a compressed condition to an expanded condition; and
an elongate balloon having a proximal opening and a distal opening, said elongate balloon being circumferentially disposed about the elongate tubular member, wherein a plurality of connections are formed between the outer wall of the elongate tubular member and the elongate balloon.

Abstract
An expandable lumen cannula which includes an elongate tube having a proximal end, a distal end, an intermediate flexible region, and a lumen therebetween. The cannula further includes a balloon occluder mounted on the distal end of the tube. The intermediate flexible region of the tube further includes an elongate generally cylindrical balloon disposed circumferentially about the flexible region which, upon inflation, expands the luminal diameter of the intermediate region. First and second inflation ports are in fluid communication with the balloon occluder and the cylindrical balloon. The cannula may optionally include a cardioplegia port disposed within the distal region of the tube, proximal the balloon occluder and distal the generally cylindrical balloon. Methods of using such a cannula are also disclosed, particularly to provide cannulation through a minimally invasive port incision, and to thereafter displace the tissues and organs adjacent an intercostal access port upon inflation and expansion of the generally cylindrical balloon.
