Design of device. The resorbable device comprised an elongated, flexible band (A) in part perforated (B) that formed a ladder structure and was connected to a locking case (C) that had a channel (D) dimensioned for reception of the band (A). A locking device (E) was configured to interlock the perforated band (B) when the band (A) was pulled through the channel (D) and a reverse-motion brake was formed. A protrusion (F) and a matching receiver (G) were arranged at the channel entrance and in the band-locking case interface. The receiver (G) was dimensioned for inclusion of the protrusion (F) when the band (A) was close to fully pushed into the locking case (C). Tissue-engaging ridges (H) were arranged on the side of the locking case of the device and on the front side (I) of the band.
