Problems solved by technology

However, these prosthetic valves can require very difficult and accurate placement, which in turn leads to unsuccessful or undesired placement or lengthy procedure times
These constraints can adversely affect the patient's health during and after the implant procedure, or even prevent some patients from being able to go through the procedure together

Abstract

In one representative embodiment, a prosthetic valve assembly for replacing a native heart valve comprises a radially expandable and compressible support structure, the support structure comprising anannular frame having a lumen extending from an inflow end to an outflow end, the support structure further comprising an annular sealing member extending radially inwardly into the lumen of the frameand having an inner peripheral portion defining an orifice, and a radially expandable and compressible valve component, the valve component comprising an annular frame and a valve structure supportedinside of the frame for permitting the flow blood through the valve component in one direction and blocking the flow of blood in the opposite direction, wherein the valve component is configured to expand within the orifice of the sealing member and engage the inner peripheral portion of the sealing member when radially expanded.

Description

technical field [0001] The present disclosure generally relates to prosthetic heart valves and devices and associated methods for implanting such heart valves. Background technique [0002] The native heart valves (ie, the aortic, pulmonary, tricuspid and mitral valves) serve an important function in ensuring an adequate blood supply downstream through the cardiovascular system. Congenital malformations, inflammatory processes, infectious conditions or diseases can render these heart valves less effective. This damage to the valves can lead to a range of cardiovascular damage or death. For many years, the definitive treatment for this condition was surgical repair or replacement of the valve during open heart surgery. However, the procedure is highly invasive and prone to many complications. As a result, elderly and frail patients with defective heart valves often go untreated. More recently, transvascular techniques have been developed for the introduction and implantat...
