Abstract
The surgical device is for supporting a mammalian organ in need of support, and in particular for treating urinary incontinence. The device has at least one first support element of elongate shape for exerting a supporting action on the organ; and at least one first traction filiform element, to be fastened to the support element. One end of the traction element constituting at least one first anchor system, activated by traction exerted on the first traction element thereby simplifying the surgical procedure.

a) applying local anesthetic in the vicinity of the organ to be supported on the future path of a prosthesis; b) making an incision and dissecting tissue facing and on either side by the mammalian organ to be supported; c) inserting a first introducer device, forming a trocar, in the passage created by said incision and tissue dissection, to one side of and away from the organ to be supported, and after, the introducer device forming a trocar is passed through a relatively tear-resistant support of said mammal, said trocar-forming introducer device of hollow tubular shape containing internally a first traction element, and a pusher element the first traction element having a proximal end and a distal end, the distal end having a first fixing system integral therewith, the first fixing system comprising a plurality of folds in the distal end of the first traction element and the proximal end of the first traction element having perforated the folds to form the first fixing system; d) applying thrust to the pusher element so as to cause a distal end of a first traction element to move out from the introducer device until the first fixing system of the first traction element is released beyond said relatively tear-resistant support; e) after releasing the first fixing system, applying traction in the vicinity of the proximal end of the first traction element, enabling the first fixing system to be positioned and deployed by being flattened out, thereby obtaining an “
umbrella”
positioning that presents a large anchoring area against said relatively tear-resistant support of said mammal;f) withdrawing the penetration trocar leaving the first fixing system in place pressed against the tear-resistant support that can thus act as a fixing point since the size of the first fixing system greatly exceeds the size of the orifice caused by penetration of the trocar; g) repeating above steps c), d), e), and f) on the other side of the organ so as to introduce a second traction element, identical to the first traction element; h) securing the proximal end of the first traction element to a first fastener element at a first end of an elongate support element so as to apply a first traction movement on the proximal end of the traction element for pre-positioning purposes; i) performing the same procedure as step h concerning the second traction element with a second fastener element provided at a second end of the elongate support element, until said elongate support element is put under tension in an appropriate position relative to said organ so as to provide the desired support of said organ; and j) closing or suturing the incision with appropriate surgical closure means. - View Dependent Claims (16, 17, 18, 19)
