The bag includes an adjustable collar at the anterior end, and a first zipper extending along the dorsal surface from an anterior end portion to a posterior end portion. An integral, elongated outer wrap extends transversely with a length sufficient to be wrapped around the bag and the animal therein to impart a uniform, calming pressure to the animal's thorax. A plurality of alternately openable and closable doors provide physician access to the animal through the bag and through the outer wrap. | 2022-08-18 |
20220257360 | PACKAGING FOR DRY TISSUE PROSTHETIC HEART VALVE - A “dry” packaging in which a prosthetic heart valve is packaged within a container with hydrogel that can be provided in many forms. Certain embodiments include hydrogel that is preloaded with glycerol or the like. The hydrogel regulates the humidity within the container through a diffusion-driven mechanism if a gradient of humidity between the inside and the outside of the hydrogel exists. Humidity regulation is important to prevent the tissue of the valve structure from drying out. When the partially-hydrated hydrogel is present within container, which is saturated with air of a predefined humidity, the water molecules from the air will be absorbed by the hydrogel if the air humidity is high (i.e. when the thermodynamics favor hydrogel hydration) or vice versa. Various embodiments are configured to also house at least a portion of a delivery device for delivering the prosthetic heart valve. | 2022-08-18 |
