Abstract
A percutaneous valve device and system are provided, which improve sealing between the anchor and native anatomy. The anchor includes a space-occupying material, such as a hydrogel, on an external surface that swells when exposed to an aqueous environment, filling gaps between the anchor and the native anatomy, and thereby serves as a valve seal.
Claims28
A percutaneous valve device comprising:
- a valve member having a plurality of valve leaflets;
- an anchor for anchoring said valve member at a location of implantation;
- and
- a space-occupying material;
- wherein said space-occupying material is exposedly located on a surface of said anchor and swells when said anchor is placed in an aqueous environment.
2 more elements
A method of manufacturing of a percutaneous valve device having improved sealing properties, comprising:
- a) mounting an anchor on a mandrel;
- b) applying one or more layers of a biocompatible material base coat onto said anchor while rotating said mandrel;
- c) drying said base coat layer;
- d) applying a space-occupying material layer to said anchor while rotating said mandrel;
- and
- e) drying said space-occupying material layer.
3 more elements
A method of improved sealing of a percutaneous valve device, the method comprising:
- providing a modular percutaneous valve device comprising a valve module and a support structure, said valve module having a folded unassembled delivery configuration and an assembled working configuration, said support structure having a radially compressed delivery configuration and a radially expanded working configuration, said valve module and support structure designed for combination into a working percutaneous valve device after deployment from a delivery device, said support structure having a space-occupying material attached to a surface thereof, said support structure stored in a dry environment until use and said valve module stored in a liquid environment until use;
- loading said support structure and valve module into a delivery device;
- deploying said support structure and valve module from said delivery device into a tubular structure having a liquid environment;
- expanding said support structure within said tubular structure;
- and
- combining said support structure and valve module to form an assembled valve device in said liquid environment of said tubular structure, wherein said space-occupying material has the property of swelling in a liquid environment to filling gaps between surfaces with which it contacts.
