Abstract
An intravascular occlusion balloon catheter having a removable hub, a profile sized to approximate a guidewire, and a means for venting air from the balloon. The removable hub and the small profile allow the occlusion balloon catheter to be used as a guidewire. The venting means allows air to be easily and reliably removed from the balloon prior to use.
Claims34
A distal occlusion device comprising:
- a tubular shaft having a proximal end, a distal region, an exterior, and an exterior wall;
- an inflatable device disposed near the shaft distal region and having an interior;
- a first lumen extending through the shaft and being in fluid communication with the inflatable device interior;
- a second lumen extending between the inflatable device interior and a first port, first port being disposed along the shaft at a position that is more proximal than the inflation device;
- and
- a plug dimensioned for disposition within, and occlusion of, the second lumen, the plug disposed to allow selective occlusion of the second lumen.
A balloon catheter, comprising:
- an elongate shaft having a first lumen defined therein, a second lumen defined therein, a proximal end region, and a distal end region;
- an inflatable member coupled to the shaft near the distal end region, the inflatable member having an interior;
- wherein the first lumen extends from the interior of the inflatable member to a first port defined in the shaft at a position between the inflatable member and the proximal end region of the shaft;
- and
- a plug disposed in the first lumen that is configured to selectively occlude the first lumen.
A balloon catheter, comprising:
- a catheter shaft having a vent lumen and an inflation lumen defined therein, a first end region, and a second end region;
- an inflatable balloon coupled to the shaft near the first end region, the balloon having an interior;
- wherein the vent lumen extends from the interior of the balloon to a vent hole defined in the shaft at a position between the balloon and the second end region of the shaft;
- and
- a plug disposed in the vent lumen that is configured to selectively occlude the vent lumen.
A balloon catheter, comprising:
- a catheter shaft having balloon end and a manifold end;
- a balloon coupled to the catheter shaft near the balloon end, the balloon having an interior;
- wherein an inflation lumen is defined in the catheter shaft that is in fluid communication with the interior of the balloon;
- wherein a vent lumen is defined in the catheter shaft that extends from the interior of the balloon to a vent hole defined in the shaft, the vent hole being positioned between the manifold end of the shaft and the balloon;
- and
- a plug movably disposed in the vent lumen.
The catheter of claim wherein the plug is movable between a first position where the plug seals the interior of the balloon and a second position that opens the interior of the balloon to the vent hole.
