Tension-free elastic tape
View Patent ↗The invention relates to a tension-free elastic tape that is used for the surgical treatment of female urinary incontinence. The inventive tape has a textile structure that allows ingrowth of the tape into the connective tissue. On its longitudinal edges, the tape has edge threads ( 2, 4, 6, 8 ) that project from the textile structure of the tape and that especially facilitate a good primary anchoring of the tape in the tissue. The edge threads are firmly incorporated in the structure of the tape.
1. Tension-free elastic tape for the surgical treatment of female urinary incontinence, comprising:
the tape having a textile structure in the form of a knitted fabric, wherein the textile structure enables the ingrowth of the connective tissue,
whereby the textile structure of the tape is comprised of a first thread pattern of base threads, whereby the tape has longitudinal edges, whereby threads running along the edges of the tape in a direction parallel to a longitudinal direction of the tape form edge threads, and the edge threads form loops that project laterally in a plane of the tape beyond the edge of the tape without open ends from the longitudinal edges of the thread pattern of base threads, the loops having loop openings of about 0.02 to 1.0 mm 2 at the longitudinal edges of the tape for a primary anchoring of the tape in the tissue and whereby the edge threads are directly and firmly incorporated in the structure of the first thread pattern of said base threads.
2. The tape according to claim 1 , characterized in that the knitted fabric is in the form of a terry cloth.
3. The tape according to claim 1 , characterized in that the tape is formed primarily or exclusively of monofils.
4. The tape according to claim 1 , characterized in that the tape is formed primarily of multifils.
5. The tape according to claim 1 , characterized in that the tape is made of non-reabsorbable material.
6. The tape according to claim 1 , characterized in that the tape is made of at least two different filament materials.
7. The tape according to claim 6 , characterized in that at least one of the filament materials is reabsorbable.
8. The tape according to claim 7 , characterized in that the edge threads consist of reabsorbable filament material.
9. The tape according to claim 1 , characterized in that the edge threads are secured by a floating thread.
10. The tape according to claim 1 , characterized in that the threads comprises a non-reabsorbable polymer material selected from the group consisting of polyethylene (PE), polypropylene (PP), polyester, polyvinylidene fluoride (PVDF), polytetrafluoroethylene (PTFE), other fluoride-containing polymers, polyurethane (PUR), polyetherketone and polyphenylene sulfide.
11. The tape according to claim 1 , characterized in that the threads comprises a reabsorbable polymer material selected from the group consisting of alpha and beta hydroxycarboxylic acids, polyglycolic acids (PGA), reabsorbing polymers and polyester amides.
12. Tension-free elastic tape for the surgical treatment of female urinary incontinence, comprising:
the tape having a textile structure in the form of a knitted fabric, wherein the textile structure enables the ingrowth of the connective tissue, the textile structure of the tape comprised of a first thread pattern of base threads, and whereby the tape has longitudinal edges; and
edge threads provided at the edges of the tape in a direction parallel to a longitudinal direction of the tape, the edge threads forming a looped second thread pattern that projects from the longitudinal edges of the thread pattern of base threads and the knitted fabric completed in the peripheral area by the edge threads forming loops on the two longitudinal edges of the tape, said loops projecting laterally in a plane of the tape beyond the edge of the tape without open ends, the loops having loop openings of about 0.02 to 1.0 mm 2 at the longitudinal edges of the tape, the loops provided on the longitudinal edges of the tape and projecting from the textile structure of the tape to ensure a primary anchoring of the tape without coming undone from the textile structure of the tape, and providing a primary anchoring of the tape in the tissue, the edge threads directly and firmly incorporated in the structure of the first thread pattern of said base threads.
