Abstract
A catheter having a distal end for insertion into a lumen of a patient's body includes a deployable semi-permeable membrane for trapping debris dislodged by a stent while allowing perfusion of body fluid through the membrane, mounted distally on said catheter; a stent mounted proximally of the membrane on the catheter; and a deployment system on the catheter for deploying the membrane in advance of deploying the stent. The deployment system is common to both the membrane and the stent. It includes a respective deployment balloon for each of the membrane and the stent. Deployment of the membrane in advance of the stent is controlled by differences in pressure-diameter characteristics of the respective deployment balloons. The deployable semi-permeable membrane is a selectively controllable collapsible mechanism.
