Cardiac implant delivery system
First Claim
1. A delivery system configured for delivering an interventional device to a targeted treatment area within a body, the delivery system comprising:
- a steerable catheter having a proximal end and a distal end; and
an interventional device delivery system positioned within the steerable catheter and configured to be translatable within the steerable catheter so as to selectively deploy the interventional device beyond the distal end of the steerable catheter, the interventional device delivery system comprising;
a shaft; and
a sheath operatively coupled to the shaft, the sheath having a first portion, a second portion, and a space defined by the first portion and the second portion, the first portion of the sheath enclosing a first portion of the interventional device, the second portion of the sheath enclosing a second portion of the interventional device, and the first and second portions of the sheath being selectively moveable relative to one another and relative to the interventional device so as to;
selectively deploy the first portion of the interventional device from the sheath while maintaining the second portion of the interventional device within the sheath, oralternatively, selectively deploy the second portion of the interventional device from the sheath while maintaining the first portion of the interventional device within the sheath, andonce one portion of the interventional device is deployed and positioned at the targeted treatment area, move the other portion of the sheath to selectively deploy the other portion of the interventional device,wherein a portion of the sheath is translatable upon subjection to a hydraulic force, from a fluid ejected into the space enclosing the interventional device prior to the sheath separating to deploy the interventional device, to deploy one of the first portion or the second portion of the interventional device.

Abstract
The present disclosure relates to delivery systems for delivering and deploying interventional devices to a targeted area within a body, such as delivering a replacement heart valve to a targeted heart valve. A delivery device includes a steerable catheter and a replacement valve delivery system positioned within the steerable catheter and configured to be translatable within the steerable catheter. The steerable catheter includes one or more control wires running from a distal end of the catheter to a handle at the proximal end of the catheter. Each control wire is coupled to a control of the handle such that manipulation of the control provides deflection and control of the steerable catheter.

14. A delivery system configured for delivering a replacement heart valve to a targeted heart valve within a body, the delivery system comprising:
-
a catheter configured to house a deployable replacement valve, the catheter having a proximal end and a distal end; a distal tip enclosing a distal section of the replacement valve, the distal tip being distally translatable relative to the replacement valve; and a sheath enclosing a proximal section of the replacement valve, the sheath being proximally translatable relative to the replacement valve, the distal tip and the sheath forming a space for the replacement heart valve, wherein the distal tip is distally translatable upon subjection to a distally oriented hydraulic force, from a fluid ejected into and filling the space of the sheath in a closed state in which the sheath is enclosing the replacement valve, to deploy the distal section of the replacement valve, and wherein the sheath is proximally translatable to deploy the proximal section of the replacement valve. - View Dependent Claims (15, 16)

17. A delivery system configured for delivering a replacement heart valve to a targeted heart valve within a body, the delivery system comprising:
-
a catheter configured to house a deployable replacement valve, the catheter having a proximal end and a distal end; and a sheath enclosing the replacement heart valve, the sheath also defining an inter-luminal space through which at least a portion of a shaft extends, the shaft including a plurality of fluid ports enabling the passage of fluid into the inter-luminal space so as to cause the sheath to translate proximally relative to the replacement heart valve to deploy the replacement heart valve, the inter-luminal space receiving the fluid from the plurality of fluid ports also includes the replacement heart valve, the fluid being present within the inter-luminal space prior to the sheath translating proximally relative to the replacement heart valve to deploy the replacement heart valve. - View Dependent Claims (18, 19, 20)
