  • Patent number: 8287580
    Abstract: For post-mortem prolongation of the viability of an organ (7, 8, 50, 51) in a donor body, a flow of a solution is introduced from outside the body between a pair of barriers (21, 22) and a return flow including previously introduced quantities of the solution is led to the outside of the body. During a flushing phase, the flow including blood flushed out of the organ (7, 8, 50, 51) is discharged to a drain. Subsequently during a recirculation phase, solution returned from the body is cooled and/or oxygenated and recirculated from outside the body back into the body between the barriers. A system for carrying out the method is also described.

  • Patent number: 7776081
    Abstract: The invention relates to medical devices, in particular condoms/drains, that find use in anastomosis. Thus the present invention relates to these medical devices per se, to a medical kit comprising these medical devices, to the use of these medical devices, to a method for medical treatment involving application of these medical devices to an organism who is in need thereof as well as to the use of certain biocompatible, biodegradable synthetic polymers in the preparation of a medical device for the treatment of a disease or a condition which requires anastomosis. The medical devices of the present invention are typically condom shaped and are used for the protection of anastomosis. The devices comprise a tubular shaped part which is made of a biocompatible, biodegradable polymer. The devices may be applied by stapling.
