Prosthetic valves and related inventions
First Claim
1. An apparatus, comprising:
- a prosthetic valve configured to be implanted within a native valve annulus of a heart between an atrium and a ventricle of the heart, the prosthetic valve including a tubular stent body having an atrial end and an opposite, ventricle end, an anterior side and an opposite, posterior side, and a collar support portion extending from the atrial end of the body, anda set of valve leaflets disposed in a lumen defined by the body and configured to permit blood flow through the body from the atrial end to the ventricle end of the body and to inhibit blood flow from the ventricle end to the atrial end of the body when the valve is disposed within a native valve annulus,the body being self-expandable from a compacted configuration to an expanded configuration in which the collar support portion extends radially outwardly from the atrial end of the body,the body having a first height on the posterior side and a second height on the anterior side greater than the first height when viewed in a side view and in the expanded configuration such that the collar support portion slopes downward from the anterior side of the body to the posterior side of the body when the body is in the expanded configuration.

Abstract
This invention relates to the design and function of a compressible valve replacement prosthesis, collared or uncollared, which can be deployed into a beating heart without extracorporeal circulation using a transcatheter delivery system. The design as discussed focuses on the deployment of a device via a minimally invasive fashion and by way of example considers a minimally invasive surgical procedure preferably utilizing the intercostal or subxyphoid space for valve introduction. In order to accomplish this, the valve is formed in such a manner that it can be compressed to fit within a delivery system and secondarily ejected from the delivery system into the annulus of a target valve such as a mitral valve or tricuspid valve.

12. An apparatus, comprising:
-
a prosthetic valve for implantation in a native valve annulus of a heart between an atrium and a ventricle of the heart, the prosthetic valve including a tubular stent body having an atrial end and an opposite, ventricle end, an anterior side and an opposite, posterior side, and a collar support portion extending from the atrial end of the body, the atrial end defining an atrial orifice, the ventricle end defining a ventricle orifice; and a set of valve leaflets disposed in a lumen defined by the body and configured to permit blood flow from the atrial end to the ventricle end of the body and to inhibit blood flow from the ventricle end to the atrial end of the body when the valve is disposed within a native valve annulus of a heart, the body being self-expandable from a compacted configuration to an expanded configuration in which the collar support portion extends radially outwardly from the atrial end of the body, when the body is in the expanded configuration, the atrial orifice is laterally offset from the ventricle orifice of the body. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
