Abstract
The invention provides a device having first and second balloons. Each of the first and second balloons communicates with an inflation lumen. A differential pressure gauge communicates with both inflation lumens. Each of the inflation lumens also communicates independently with a pump for inflating the balloon. The pressure gauge may include a shut-off valve for terminating inflation in the second balloon when the pressure within the first balloon exceeds the pressure in the second balloon. The pressure gauge may also include a pressure limiter. Methods of using the devices for measuring diameter and pressure of a balloon occluder deployed in a vessel or body cavity are disclosed.
Claims11
A method for occlusion of a vessel or body cavity, comprising the steps of:
- inserting a first balloon into the lumen of a vessel or body cavity while maintaining a second balloon outside of the vessel or body cavity, the first and second balloons communicating respectively with first and second inflation lumens, each inflation lumen communicating with a pressure gauge;
- and
- inflating the first and second balloons until the pressure gauge indicates that the first balloon engages the lumenal wall of the vessel or body cavity.
