Such damage to the valve can lead to serious cardiovascular damage or death
For many years, the definitive treatment for this condition has been surgical repair or replacement of the valve during open heart surgery, but such surgery is prone to several complications

Embodiment Construction

[0081]In particular embodiments, a delivery device for implanting a prosthetic, transcatheter heart valve through a patient's vasculature includes an adjustment device for adjusting the balloon relative to the crimped prosthetic valve (and / or vice versa). However) the location. A balloon catheter can extend coaxially with the guiding (or flexing) catheter, and a balloon member on the distal end of the balloon catheter can be placed proximal or distal to the crimped prosthetic valve. As described in more detail below, the balloon member and crimped prosthetic valve can be entered into the patient's vasculature through an introducer sheath, and once the balloon member and crimped prosthetic valve are in place in the body, the prosthetic valve and bulb can be adjusted. The relative position of the balloon member so that the balloon member is within the framework of the prosthetic valve so that the prosthetic valve can eventually expand over the treatment site. Once the crimped p...

Abstract

Described herein are systems and methods from delivering prosthetic devices, such as prosthetic heart valves, through the body and into the heart for implantation therein. The prosthetic devices delivered with the delivery systems disclosed herein are, for example, radially expandable from a radially compressed state mounted on the delivery system to a radially expanded state for implantation using an inflatable balloon of the delivery system. Exemplary delivery routes through the body and into the heart include transfemoral routes, transapical routes, and transaortic routes, among others.

Description

technical field [0001] The present disclosure relates to embodiments of a delivery system for implanting a prosthetic heart valve. Background technique [0002] Prosthetic heart valves have been used for many years to treat heart valve disease. Native heart valves such as the aortic, pulmonary, and mitral valves play a vital role in ensuring an adequate supply of blood to flow forward through the cardiovascular system. These heart valves can be made to function less effectively due to congenital, inflammatory or infectious conditions. Such damage to the valves can lead to serious cardiovascular damage or death. For many years, the definitive treatment for this condition has been surgical repair or replacement of the valve during open heart surgery, but such surgery is prone to several complications. More recently, a transvascular technique has been developed to introduce and implant a prosthetic heart valve using a soft catheter in a less invasive manner than open heart s...
