Abstract
Balloon based therapy devices for treatment of diseased vessels are described. The devices are adapted for active aspiration of a closure zone prior to delivery of a closure agent. The devices may be used for treatment of diseased veins in the lower limbs and pelvis.
Claims24
A vein treatment device, comprising:
- a catheter shaft having a proximal end and a distal end;
- a hub coupled to the proximal end;
- a distal balloon on the catheter shaft adjacent to the distal end, wherein the distal balloon is a compliant balloon;
- an aperture in the catheter shaft proximal to the distal balloon;
- an inflation lumen within the catheter shaft in fluid communication with an interior volume of the distal balloon and an inflation port on the hub;
- a fluid lumen within the catheter shaft in fluid communication with the aperture and a fluid port on the hub;
- and
- a plurality of mechanical abrasion elements spaced about the surface of the catheter shaft and extending along the distal balloon, each mechanical abrasion element of the plurality of mechanical abrasion elements comprises a tissue contacting surface and a distal balloon contacting surface, a proximal terminal end and a distal terminal end wherein the proximal terminal end of each of the mechanical abrasion elements is coupled to the catheter shaft proximal to the aperture in the catheter shaft proximal to the distal balloon and the distal terminal end of each of the mechanical abrasion elements is coupled to the catheter shaft distal to a distal most end of the distal balloon.

- an inflation lumen within the catheter shaft in fluid communication with an interior volume of the compliant balloon and an inflation port on the hub;
- a fluid lumen within the catheter shaft in fluid communication with the aperture and a fluid port on the hub;
- and
- a plurality of mechanical abrasion elements arranged about the compliant balloon, each of the mechanical abrasion elements comprising a distal terminal end, a proximal terminal end and a tissue engagement zone directly adjacent to an outer surface of the compliant balloon, wherein in use a partial inflation of the compliant balloon causes the tissue engagement zone of each of the plurality of mechanical abrasion elements to come into contact with a vein wall of the vein, further wherein the length of each one of the plurality of the mechanical abrasion elements has a length between the proximal terminal end and the distal terminal end of between 70 mm and 180 mm.
