Micro sling and implantation tool for urinary incontinence and faecal incontinence treatment

An implantation system comprising a sling for urinary and faecal incontinence treatment and an implantation tool

• said sling consisting of:
• a mid-part having a length of 20 to 100 mm, two fixing tails each comprising an anchoring means, an elongated part fixed to the mid-part, and an end part fixed to the elongated part, the end part including a connection means connectable to a tool, at least one fixing tail being an autofixing tail including self-anchoring means, wherein the elongated part is substantially flat and the end part is axially disconnectable from the tool, the substantially flat elongated part of the autofixing tail consisting of substantially flat self-anchoring means, wherein
• the elongated part of the sling has a thickness of 0.3 to 1 mm,
• the end part consists of a butting surface substantially perpendicular to a distal portion of the elongated part with a chamfered or rounded edge on a surface distal to the elongated part,
• the connection means of the end part is within the butting surface and consists of a fixing hole, substantially parallel to the distal portion of the elongated part,
• said implantation tool comprising
• a cannula,
• an awl axially moveable inside the cannula between a protruding and a non protruding position, and an actuator of the awl, wherein
• the awl has a diameter adapted to enter into the fixing hole of the sling, the cannula being designed for not entering into said fixing hole,
• the awl comprising a tip with a stop, the stop having a diameter that is larger than the awl diameter,
• the fixing hole has a diameter smaller than the stop diameter of the awl tip of the tool and elastically deformable to allow the awl tip to cross along the fixing hole, the actuator being designed such that, in the protruding position, the stop protrudes from the end part of the sling,
• wherein the mid part of the sling is a mesh comprising a main part substantially rectangular, and two side tongues, extending from the two ends of a short side of the main part in two substantially perpendicular directions, a fixing tail extending from each of the side tongues,
• wherein the main part of the mesh of the sling comprises two lateral tongues extending in a direction substantially perpendicular to a long side of the main part, a fixing tail extending from each lateral tongue, and
• wherein the fixing tails consist of a fixing pad fixed onto only one surface of the mid part of the sling.
