Abstract
Constriction valves for catheters and method of using constriction valves are presented. The catheter valve has a conduit comprising mesh defining a lumen. The catheter also has a biasing member that is configured to bias the lumen from an open position to a closed position by altering an effective length of the conduit or altering the circumference of the conduit. The biasing member is further configured to change its configuration by changes of intraluminal pressure of the valve. A user can insert a tool into a catheter having a valve by manipulating the valve to expand a substantially closed lumen by compressing the biasing member, twisting the biasing member, or pulling on a cord coupled with the valve.
