Abstract
The disclosure generally relates to delivery devices for transcatheter delivery of a prosthesis. The delivery device includes a hollow shaft on which the prosthesis is supported. A handle assembly maintains the shaft. The delivery device further includes a guide wire that is selectively directed through the handle assembly and shaft. The guide wire directs the shaft to a target site at which the prosthesis is to be deployed. In practice, an operator managing the inner catheter controls the prosthesis positioning. The delivery devices disclosed herein are configured to ergonomically also allow the operator to control the position of the guide wire as the position of the guide wire influences the deployment position of the prosthesis. In this way, a second operator for positioning the guide wire can be omitted. Embodiments of the disclosure are believed to improve positioning predictability and ease of use.
