Patent number: 11930809Abstract: Described herein are enhanced compositions and methods for storing biomaterials. In certain aspects, these biomaterials include natural and engineered eukaryotic tissues. The methods described herein include storing these biomaterials in such a manner that reduces or prevents the loss of biomaterial properties (e.g., extracellular matrix integrity, cell viability, or a combination thereof) occurring either during storage or after removal of the biomaterial from storage.

Publication number: 20160042084Abstract: Methods of monitoring, maintaining, and/or restoring viability of at least one organ in a perfusion apparatus are disclosed. The methods include monitoring data comprising information relating to events occurring while at least one organ is present in a perfusion apparatus to form a data record. And they further include connecting the perfusion apparatus to a network through wiring or wirelessly, and continuously uploading the data record to a database at a location away from the perfusion apparatus in such a manner that a database computer that obtains the data record from the database can at least one of manage, track, monitor, and diagnose the at least one organ in the perfusion apparatus in real-time based upon the information in the data record.Type: ApplicationFiled: October 21, 2015Publication date: February 11, 2016Inventors: Donald R.

Patent number: 8962303Abstract: An organ perfusion apparatus and method monitor, sustain and/or restore viability of organs and preserve organs for storage and/or transport. Other apparatus include an organ transporter, an organ cassette and an organ diagnostic device. In perfusion, organ perfusion pressure is preferably controlled in response to a sensor disposed in an end of tubing placed in the organ, by a pneumatically pressurized medical fluid reservoir, providing perfusion pressure fine tuning, overpressurization prevention and emergency flow cut-off. In the hypothermic mode, the organ is perfused with a medical fluid, preferably a simple crystalloid solution containing antioxidants, intermittently or in slow continuous flow. The medical fluid may be fed into the organ from an intermediary tank having a low pressure head to avoid organ overpressurization. Viability of the organ may be automatically monitored, preferably by monitoring characteristics of the medical fluid perfusate.Type: GrantFiled: August 10, 2011Date of Patent: February 24, 2015Assignee: Lifeline Scientific, Inc.Inventors: Donald R.
