Abstract
An apparatus is for performing a medical procedure using an inflation fluid. The apparatus includes a shaft with two inflation lumens for transmitting the inflation fluid. A balloon supported by the shaft has an interior capable of being inflated by the inflation fluid transmitted through the inflation lumens of the shaft. The tubes defining the inflation lumens provide two outlets for transmitting different flows of the inflation fluid to the interior of the balloon. A stent and related methods are also disclosed.
Claims18
An apparatus comprising:
- an inflatable balloon having proximal and distal cones and an interior for receiving inflation fluid;
- a first tube comprising a first inflation lumen with a first outlet for transmitting a first flow of the inflation fluid to the interior of the balloon;
- and
- a second tube inside the balloon having a proximal end, a distal end, a second outlet spaced from the first outlet in a longitudinal direction, and a passage between the proximal and distal ends adapted to transfer inflation fluid to the second outlet for inflating the balloon;
- wherein the proximal end is located within the proximal balloon cone and the distal end is located within a distal balloon cone.
