Abstract: Disclosed is a prosthetic heart valve, wherein the prosthetic heart valve comprises: a ring-shaped stent, comprising: a mesh structure which allows the stent to be contracted or expanded in a radial direction; and a leaflet structure, comprising a plurality of leaflets, each leaflet is attached to the stent and has a first portion disposed within the stent and a second portion being wrapped to an outer circumferential side of the proximal end of the stent. With a growth of the heart, the stent can be expanded after the prosthetic heart valve is anchored, to allow the prosthetic heart valve to operate in different states, and under at least one of the different states, each leaflet has an excessive portion freely sagging to a position away from the stent along a direction from the distal end to the proximal end, to allow the stent to form a more functional valve.

Abstract: Disclosed is a prosthetic heart valve and an assembling method thereof. The prosthetic heart valve comprises a universal core which can be universally used in different implantation positions and different application scenarios, and an adapter selected from more than one adapters which are respectively suitable for the different application scenarios. The universal core has a plurality of cantilever struts softly connected by a wire to form a supporting structure for a leaflet structure. The prosthetic heart valve according to the present disclosure has better flexibility and wider application range compared with various existing prosthetic heart valves, and may save time cost and research and development cost.

Abstract: An applicator for administering a liquid to a selected location of a patient includes a main body having an interior cavity and a flexible outer wall. A frangible ampoule is configured to contain the liquid and configured to be positioned within the interior cavity of the main body. A hypodermic tube having a proximal end attached to the main body and a distal end. An applicator tip attached to the distal end of the hypodermic tube to dispense the liquid.

Abstract: A corner protector for position about a corner of an equipment sterilization tray includes a base portion having a perimeter and a first concave recess. A first wall portion extends from a first portion of the perimeter of the base portion and comprises a second concave recess. A second wall portion extends from a second portion of the perimeter and comprises a third concave recess wherein the first and second wall portions are substantially perpendicular to each other. A connecting portion extends from a third portion of the perimeter wherein the connecting portion connects the first and second wall portions to form a continuous wall.
