Temporary Vein Blocker
Permanent implantable vein blocker (e.g. V-Block, VVT) ave been invented to reliably occlude a vein segment, e.g. the saphenofemoral junction during catheter foam applications in order to prevent femoral vein thrombosis.
The VENARTIS work group is convinced that many patients will object to receiving an implant, even a resorbable one, when similar effects can be achieved without (e.g. laser, glue, RF).
Therefore we designed a temporary vein blocker, which is positioned and deployed prior to foam injection, and collected after 1 - 2 minutes of foam exposure.
Compared to former attempts with occluding ballons, the device works much more precise and well adaptable to different diameters and anatomic variants.
