Claims
- 1. A balloon catheter comprising:
- an inner tubular member having a proximal end, a distal end, and a lumen extending therethrough;
- an outer sheath having a proximal end and a distal end, said sheath being disposed coaxially over the inner tubular member to define an inflation lumen therebetween; and
- an elastomeric balloon attached to the distal ends of the inner tubular member and the outer sheath to receive inflation medium from the inflation lumen, wherein the balloon is inflatable to a spherical shape having a diameter from 4 mm to 14 mm.
- 2. A balloon catheter as in claim 1, wherein the inner tubular member has a region of maximum flexibility at its distal end within the balloon, wherein the region has a length in the range from 1 cm to 3 cm.
- 3. A balloon catheter as in claim 2, wherein the inner tubular member has a proximal region which comprises braid reinforcement.
- 4. A balloon catheter as in claim 1, wherein the inner tubular member has an outer diameter in the range from 0.33 mm to 4 mm.
- 5. A balloon catheter for insertion into a body lumen, said catheter comprising:
- an inner tubular member having a proximal end, a distal end, and a lumen extending therethrough;
- an outer sheath having a proximal end and a distal end, said sheath being disposed coaxially over the inner tubular member to define an inflation lumen therebetween; and
- an elastomeric balloon attached to the distal ends of the inner tubular member and the outer sheath, said balloon being selectively expandable to a spherical size which can partially or totally occlude the particular body lumen.
