Vessel compression devices and methods

摘要

Embodiments of the present disclosure comprise compression devices and methods for applying intermittent and localized vessel compression. The compression devices and methods as described herein can improve fistula circuit maturity rates by promoting vein dilation. An aspect of the present disclosure is directed toward depressor designs actuated using actuator wire(s).

主权项

1. A device comprising:
a support piece having a compression region and a strap releasaby attached to the support piece; a depressor having a cylindrical upper portion disposed within an aperture in the compression region and a base portion coupled to the upper portion, wherein the base portion comprises a focal end having a surface profile; and an actuator wire coupled to the support piece and the upper portion of the depressor such that when an electrical current is applied to the actuator wire, the wire changes in length forcing the depressor to compress a vessel.
