Embodiment Construction

[0049] Referring now to the exemplary drawings in figure 1 , shows a packaging assembly 1000 for storing a bioprosthetic heart valve 10 . Packaging assembly 1000 may include subassembly 100 including valve holder 110 configured to hold bioprosthetic heart valve 10 and clamp 130 configured to receive shaft 112 of valve holder 110 . As will be discussed in more detail below, subassembly 100 holding bioprosthetic heart valve 10 may be placed in a container, such as a bottle (not shown), storage tray 200, and further processed for storage and shipping.

[0050] refer to figure 2 The valve holder 110 can include a cap 118 coupled to the first end 114 of the shaft 112 and an engagement structure 120 coupled to the second end of the shaft 112 . In one embodiment, the cap 118 can include a bore with internal threads 124 and the shaft 112 can have a shaft width W 1 and a substantially circular cross-section, and the engagement structure 120 can be configured to removably couple to ...

Abstract

A packaging assembly for storing a bioprosthetic heart valve is disclosed. The packaging assembly can include a sub-assembly comprising a valve holder configured to hold the bioprosthetic heart valve, and a clip configured to receive a shaft of the valve holder. The clip can comprise a body having an outer periphery and opposing inner edges. The opposing inner edges can define a slot in the body for receiving the shaft of the valve holder. The slot can be open at a first end of the body and extend, along a longitudinal axis of the body, from the first end to a docking aperture. The clip can further comprise a compliance feature in an interference-fit area of the slot adjacent to the docking aperture. The compliance feature can comprise a cutout adjacent to each of the opposing inner edges such that each of the opposing inner edges defines a beam within the interference-fit area.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of U.S. Provisional Application No. 62 / 882415, filed August 2, 2019, which is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates generally to packaging for prosthetic heart valves, and more particularly to packaging subassemblies including clips with compliant components. Background technique [0004] Heart valve disease remains an important cause of morbidity and mortality. Currently, the mainstay of treatment for heart valve disease is heart valve replacement. Prosthetic heart valves can be environmentally sensitive and must be packaged to protect the valve from shock and contamination during shipment. Therefore, it is important for the packaging to provide a structure that both protects the heart valve and allows easy removal of the valve without damage or contamination. [0005] Manufacturers have suspended bioprosthetic he...
