Abstract
An implantable valve having a valve element or leaflet and a base that is attachable to a vessel wall using a connector such as a screw, pin or a staple. The valve can be implanted using a catheter to position the valve in a desired location and drive the connector into the vessel wall. The valve can be used as a venous valve to control blood flow within the veins, arteries, heart or the aorta of a patient.
Claims42
A body lumen valve comprising:
- a base;
- a valve element comprising tissue disposed on a mesh, said valve element connected to the base such that the valve moves relative to the base between an open position and a closed position;
- and
- a connector that attaches the base directly to a body lumen surface region.
1 more element
A valve comprising:
- a base;
- a connector that attaches the base directly to a body lumen surface region;
- and
- a tubular wall attached to the base, the tubular wall formed of a silicone material and having a distal end with a distal opening and a proximal end with a proximal opening such that fluid flow from the distal end to the proximal end forces the tubular wall into an open position and fluid flow from the proximal end to the distal end forces the tubular wall into a closed position.
1 more element
An implantable venous valve comprising:
- a base;
- a connector that attaches the base directly to a body lumen surface region;
- a leaflet comprising a rim and a center portion, the rim being thinner than the center portion;
- and
- a hinge connecting the base to the leaflet such that the leaflet moves relative to the base between an open position and a closed position.
