<P>PROBLEM TO BE SOLVED: To provide a system and a method for enhancing the closure of a separated tissue with an external patient interface. <P>SOLUTION: A first fluid transfer component FTC1 comprises a strip of porous material, such as rayon, with liquid wicking properties. FTC1 can be placed directly on a suture line for transferring fluid exuded therethrough. FTC.2 comprises a suitable hydrophobic foam material, such as polyurethane ether, and is placed over the underdrape slot in communication with FTC1. Negative pressure is applied to FTC2 through a connecting fluid transfer component FTC.3. A tissue closure method includes a manual operating mode using a manual suction device with an automatic shut off for discontinuing suction when a predetermined volume of fluid has been drained. An automatic operating mode utilizes a microprocessor, which can be preprogrammed to respond to various patient and operating conditions. <P>COPYRIGHT: (C)2013,JPO&INPIT |
