A wound drainage and hemostasis promoting medical device (1) is 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 a 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.
