AI Technical Summary

Problems solved by technology

For example, it is difficult to control the forces exerted on the prosthetic heart valve and / or delivery device during the implant procedure
These difficulties are compounded when the delivery device is placed in a tortuous path, such as in the patient's vasculature
It may also be difficult to release mechanically expandable prosthetic heart valves from the delivery device
Additionally, given the number of moving parts to control, operation of a typical delivery device can be difficult and / or time consuming for the user

example 1

[0225] Example 1. A delivery device for implanting a prosthetic heart valve, the delivery device comprising: a handle, a first shaft, a plurality of actuation shafts, and a control mechanism. The first shaft has a first end portion, a second end portion, and one or more lumens extending from the first end portion to the second end portion. The first end portion is coupled to the handle. The actuation shafts each have a proximal end portion and a distal end portion, and the actuation shafts extend through the one or more lumens of the first shaft. The control mechanism is coupled to the actuation shaft and the handle. The control mechanism includes a first mode of operation and a second mode of operation. In the first mode of operation, the proximal end portions of the actuation shaft are axially movable relative to each other and relative to the first shaft, and in the second mode of operation, the The actuation shaft is simultaneously movable axially.

example 2

[0226] Example 2. The delivery device of any example herein, particularly example 1, wherein the control mechanism comprises a force control mechanism.

example 3

[0227] Example 3. The delivery device of any of the examples herein, particularly example 2, wherein the force control mechanism comprises a pulley, wherein the proximal end portions of two of the actuation shafts are coupled via the pulley. wherein when the tension in said two of said actuation shafts is not uniform, said proximal end portions of said two of said actuation shafts move axially relative to each other and the The pulley rotates.

Abstract

The invention relates to a delivery device for implanting a prosthetic heart valve. The delivery device for implanting a prosthetic valve includes a handle, a first shaft, a plurality of actuation shafts, and a control mechanism. The first shaft has one or more lumens extending from a first end portion to a second end portion. The actuation shafts each have a proximal end portion and a distal end portion, and the actuation shafts extend through the one or more lumens of the first shaft. The control mechanism is coupled to the actuation shaft and the handle. The control mechanism is configured such that, in a first mode of operation, the actuation shafts can move axially relative to each other, and such that, in a second mode of operation, the actuation shafts can move axially simultaneously. Additionally or alternatively, the first shaft may include a plurality of helical lumens configured to receive the actuation shaft.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of U.S. Provisional Application No. 62 / 945,039, filed December 6, 2019, which is incorporated herein by reference. technical field [0003] The present disclosure relates to implantable mechanically expandable prosthetic devices, such as prosthetic heart valves, and to delivery devices and methods for implanting prosthetic heart valves. Background technique [0004] The human heart can suffer from various valvular diseases. These valvular diseases can lead to severe heart insufficiency, eventually requiring repair of the natural valve or replacement of the natural valve with an artificial valve. There are many known prosthetic devices (eg, stents) and artificial valves, as well as many known methods of implanting these devices and valves in the human body. Percutaneous and minimally invasive surgical approaches are used in a variety of procedures to deliver prosthetic medical devic...
