Abstract
A wound drainage and hemostasis promoting medical device (1) are disclosed. A balloon (15) is temporary inflated and arranged outside a sheath (10), in contact with tissue surrounding a wound cavity for hemostasis promotion. The drainage device comprises a fluid communication channel for wound exudate from wound. The balloon is deflated and retracted into said sheath for removal from said wound cavity. Thus the medical device is percutaneously retractable from said confined wound.
Claims17
A medical procedure of draining exudate from a wound cavity of a post surgical confined wound and promoting hemostasis for therapeutic treatment of said wound, said procedure comprising:
- surgically creating a cutaneous opening at a distance from said confined wound;
- providing a medical drainage device having a fluid communication channel;
- percutaneously arranging a distal end of said fluid communication channel in said wound cavity of said post surgical confined wound and a proximal end of said fluid communication channel outside of said wound cavity, and thus draining wound exudate from said distal end to said proximal end of said fluid communication channel;
- cutaneously closing said confined wound;
- providing a hemostasis promoting medical device having an elongate sheath, an inflatable and deflatable balloon longitudinally moveable relative to said sheath, and a hollow inflation and deflation tubular member along said elongate sheath in fluid communication with said balloon;
- percutaneously arranging said sheath through said cutaneous opening with a proximal end of said elongate sheath outside said wound cavity and a distal end of said elongate sheath in said wound cavity with said balloon deflated in said sheath;
- discharging said balloon out of said distal end of said sheath in said wound cavity thereof;
- inflating said balloon to a desired pressure through said tubular member to be at least partly in apposition with tissue surrounding said wound cavity for said hemostasis promotion during a hemostasis promoting time;
- and
- deflating said balloon, reloading said deflated balloon into said distal end of said sheath, and retracting said distal end of said sheath out of said wound cavity through said cutaneous opening;
- wherein the procedure further comprises providing nitric oxide (NO) to tissue of said wound emanating from a liquid being a source of nitric oxide (NO) inside said balloon, said balloon being filled with said liquid when inflated and being fluid impermeable whereby the liquid source of nitric oxide (NO) is kept separate from the wound tissue, and said balloon being permeable for nitric oxide (NO);
- and,
- providing an ultrasonic sound generator, generating ultrasonic sound waves with said ultrasonic sound generator, and propagating said ultrasonic sound waves through said liquid towards said inflated balloon and through said balloon to said surrounding tissue.
