Abstract
A catheter for introduction into a body cavity comprises a flexible outer tube with a handle member and proximal and distal ends and a flexible inner tube with a holder. The exterior surface of the outer tube has a first cross sectional shape along at least a portion of its length with the inferior surface having a second cross section shape along at feast a portion of its length. The inner tube has an exterior surface having a third cross section shape along at least a portion of its length. The third cross section shape has a radius less than said second cross section shape and is configured to prevent more than a predetermined rotation when received within in the second cross section shape of the outer tube. The holder has a holder stop proximate its distal face with the distance between the proximal face of the handle member and the stop being equal to the length of the membrane. This ensures that once the stop contacts the handle member, the membrane will be fully deployed.
