Method and system for packaging and preparing a prosthetic heart valve and associated delivery system
First Claim
1. A packaging system for storing a prosthetic valve and an elongated delivery system in a non-fluid environment, the packaging system comprising:
- a tray for securing both a prosthetic valve and an elongated delivery system; and
a valve cover, wherein the prosthetic valve is maintained in a compressed state inside the valve cover and around a distal portion of the elongated delivery system and the valve cover is removable from the prosthetic valve and the delivery system, the tray includinga cavity comprising an open end, a floor, and a peripheral side wall defining a depth of the cavity, the cavity sized and shaped to house the valve cover and the prosthetic valve;
a mounting surface to removably couple the valve cover to the cavity floor;
an engaging surface peripherally of the cavity and elevated above the cavity floor; and
a ramp extending downwardly from the engaging surface and into the cavity through an opening defined in the peripheral side wall;
wherein the engaging surface and the ramp are configured to secure at least a portion of the elongated delivery system externally of the cavity.

Abstract
A packaging system for storing a prosthetic valve and an elongated delivery system in a non-fluid environment. The packaging system includes a tray for securing both a prosthetic valve and an elongated delivery system. The tray includes a cavity sized and shaped to house a valve cover containing the prosthetic valve and at least part of the distal portion of the elongated delivery system. A mounting surface removably couples the valve cover to the cavity floor and to prevent the valve cover from moving. An engaging surface is disposed peripherally of the cavity and is elevated above the cavity floor. A ramp extends downwardly from the engaging surface and into the cavity through an opening defined in the peripheral side wall and adjacent the floor of the cavity. The engaging surface and ramp are configured to secure at least part of the elongated delivery system externally of the cavity.

26. A method for preparing a prosthetic valve and its associated delivery system for implantation of the prosthetic valve in a patient, the method comprising:
-
(a) obtaining a tray, the tray comprising a prosthetic valve in a first compressed state inside a valve cover and coupled to an elongated delivery system, the valve cover being removable from the prosthetic valve and the delivery system, and the tray including a cavity comprising an open end, a floor, and a peripheral side wall defining a depth of the cavity, the cavity sized and shaped to house the valve cover, the prosthetic valve and at least part of a distal portion of the elongated delivery system; a mounting surface to substantially immobilize and maintain the valve cover and the prosthetic valve within the cavity; an engaging surface peripherally of the cavity and elevated above the cavity floor; and a ramp extending downwardly from the engaging surface and into the cavity through an opening defined in the peripheral side wall; wherein the engaging surface and the ramp are configured to secure at least a portion of the elongated delivery system externally of the cavity; (b) at least partially filing the cavity with a first hydrating fluid to completely immerse the prosthetic valve; (c) allowing the prosthetic valve to soak in the first hydrating fluid for a period of time; (d) flushing the elongated delivery system by delivering a second hydrating fluid into a proximal end of the elongated delivery system and causing the second hydrating fluid to pass through a lumen extending through the elongated delivery system and out of the distal portion of the elongated delivery system; and (e) causing the prosthetic valve to be loaded into a lumen of a delivery sheath associated with the elongated delivery system while the prosthetic valve is coupled to the cavity floor via the mounting surface; wherein the loading is performed by causing the delivery sheath move axially over the prosthetic valve; wherein the delivery sheath compresses and contains the prosthetic valve within a lumen of the delivery sheath in a second compressed state; and wherein a diameter of the prosthetic valve in the first compressed state is larger than a diameter of the prosthetic valve in the second compressed state; (f) removing the elongated delivery device with the prosthetic valve loaded into the lumen of the delivery sheath from the tray, including removing the distal portion of the delivery system from the valve cover and disengaging the prosthetic valve from the mounting surface; and wherein (a) through (e) are performed while the prosthetic valve is substantially immobilized and maintained within the cavity.
