Method, a device, and a system for organ reconditioning and a device for preserving an internal body organ
First Claim
1. A device for reconditioning an internal body organ having or risking a functional failure associated with a fluid collection therein, said device comprising a tube having a proximal end adapted for connection to a vacuum source, and a distal end portion having a plurality of openings, a chamber surrounding the distal end portion of the tube and the openings therein, and a flexible material occupying said chamber and forming fluid connections between a selected part of an external surface of the chamber and the openings of the distal end portion of the tube, said selected part of the external surface of the chamber being adapted for contacting the internal body organ, whereby interstitial fluid of the internal body organ adjoining said selected part of the external surface of the chamber is sucked off from the internal body organ.

Abstract
A device for reconditioning an internal body organ having or risking a functional failure or impairment associated with a fluid collection therein comprises a tube having a proximal end adapted for connection to a vacuum source, and a distal end portion having a plurality of openings. A chamber surrounds the distal end portion of the tube and the openings therein. A flexible material occupies said chamber and forms fluid connections between a selected part of an external surface of the chamber and the openings of the distal end portion of the tube. The selected part of the external surface of the chamber is adapted for contacting an external or internal surface portion of the internal body organ. Thereby, interstitial fluid of the internal body organ adjoining said selected part of the external surface of the chamber is sucked off from the internal body organ.

2. A device for reconditioning of an internal body organ having, or risking a functional failure or impairment associated with a fluid collection therein, said device comprising:
-
an organ contacting surface, which is adapted to contact the internal body organ, said organ contacting surface having, at least during the use of the device, pores allowing interstitial fluids to flow from the internal body organ through the surface, and a draining element adapted to apply a negative pressure at the organ contacting surface and adapted to lead said interstitial fluids away from the internal body organ at said organ contacting surface via said pores. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49)

51. A method for reconditioning an internal body organ having or risking a functional failure associated with a fluid collection therein, comprising the steps of
providing a tube, which has a proximal end and a distal end portion having a plurality of openings, a chamber surrounding the distal end portion of the tube and the openings therein, and a flexible material in said chamber and forming fluid connections to the openings of the distal end portion of the tube; -
contacting the internal body organ by said flexible material; and
connecting the proximal end of the tube to a vacuum source, whereby interstitial fluid of the internal body organ adjoining the flexible material is sucked off from the internal body organ. - View Dependent Claims (52, 53, 55, 56, 57, 58, 59, 60, 61, 62, 63)
