Vascular reinforcement device and method
First Claim
1. A vein reinforcement device to reduce increased vascular resistance of a vein when exposed to externally applied forces, the device including a reinforcement structure arranged to continuously overlie, in adjacent relation to, a wall of a vein, the reinforcement structure having a longitudinal dimension and a cross-sectional dimension defining an area, the longitudinal dimension being greater than the cross-sectional dimension, the reinforcement structure being longitudinally flexible and cross-sectionally resistant to area change.

Abstract
A vascular reinforcement device and method reduces increased vascular pressure of a vein in the presence of forces applied externally to the vein. The device is arranged to continuously overlie of a vein and has a longitudinal dimension and a cross-sectional dimension. The longitudinal dimension is greater than the cross-sectional dimension and is flexible while the cross-sectional dimension of the device is resistant to change. The device is deployed so as to overlie a wall of the vein. The device and method find particular advantageous application for treating preeclampsia or hypertension associated with obesity.
