Abstract

The present invention relates to a device (1) for introducing a flexible prosthesis into a surgical incision, comprising a globally tubular body (2) having a proximal end (2a) and a distal end (2b), said tubular body being designed for receiving the prosthesis in a folded configuration in a sliding way,

• • wherein the tubular body is provided with an open longitudinal slit (3) extending from said proximal end (2a) to said distal end (2b), and wherein said distal end is provided with a distal semi-tubular rounded extension (2c).

Claims

1. A kit comprising:

a prosthesis comprising a generally elongate shape defining a longitudinal axis aligned on a medial-lateral axis and a transversal axis aligned on a cranial-caudal axis, the prosthesis comprising at least one flexible biocompatible textile of elongate shape comprising a medial end, a lateral end, a cranial part and a caudal part, the textile being delimited by a peripheral outer edge formed of a convex medial edge, a convex cranial edge, a convex lateral edge and a caudal edge, and at least one reinforcing element for the textile, the reinforcing element being in the form of a resilient frame connected to the textile and set back from the peripheral outer edge, the frame comprising a convex cranial segment extending from the medial end of the textile to the lateral end of the textile along the convex cranial edge, a caudal segment substantially extending from the medial end of the textile to the lateral end of the textile and caudally spaced with respect to the convex cranial segment, a lateral corner segment joining together the convex cranial segment and the caudal segment in a region of the lateral end of the textile, and a folding segment configured for joining a medial end of the convex cranial segment to a point located on the caudal segment while leaving a region of the medial end of the textile free of any frame, wherein at least a part of the caudal segment has substantially a structure of a flat band forming undulations substantially in a plane of the textile and

a device comprising a globally tubular body having a proximal end, a distal end, a substantially oblong cross-section, and an open longitudinal slit extending from the proximal end to the distal end, and the tubular body designed for receiving the prosthesis in a folded configuration in a sliding way.

2. The kit according to claim 1, wherein the frame is able to adopt an unstressed configuration, in which the textile is deployed, and a stressed configuration, in which the frame is subjected to a transversal force directed towards the longitudinal axis, and the convex cranial segment, the caudal segment and the folding segment are substantially collected together and aligned on one folding direction, the textile forming thereby at least one fold along the folding direction.

3. The kit according to claim 2, wherein the folding segment joins the medial end of the convex cranial segment to a medial end of the caudal segment.

4. The kit according to claim 1, wherein the caudal segment is concave.

5. The kit according to claim 1, wherein the folding segment has a U shape extending towards a center of the textile.

6. The kit according to claim 1, wherein the frame is continuous.

7. The kit according to claim 1, wherein the frame further comprises a caudal extension located on the caudal segment and extending in the caudal direction toward the caudal edge of the textile.

8. The kit according to claim 1, wherein the reinforcing element is molded over the textile.

9. The kit of claim 1, wherein the proximal end of the device forms a partial funnel.

10. The kit of claim 1, wherein the distal end of the device includes a rounded extension.

11. The kit of claim 1, wherein the device further comprises markings defining a ruler along the open longitudinal slit.

12. The kit of claim 1, wherein the tubular body of the device is made of a transparent material.

13. A kit comprising:

a flexible textile based prosthesis for hernia repair, and

a device for introducing the flexible textile based prosthesis into a surgical incision, the device comprising a globally tubular body having a proximal end provided with a proximal semi-tubular extension, a distal end provided with a distal semi-tubular rounded extension, a substantially oblong cross-section, and an open longitudinal slit extending from the proximal end to the distal end, wherein the open longitudinal slit widens on the proximal semi-tubular extension and the distal semi-tubular rounded extension.

14. The kit of claim 13, wherein the flexible textile based prosthesis comprises a generally elongate shape defining a longitudinal axis aligned on a medial-lateral axis and a transversal axis aligned on a cranial-caudal axis.

15. The kit of claim 14, wherein the flexible textile based prosthesis comprises a medial end, a lateral end, a cranial part and a caudal part, the textile based prosthesis being delimited by a peripheral outer edge formed of a convex medial edge, a convex cranial edge, a convex lateral edge and a caudal edge, and at least one reinforcing element for the textile based prosthesis, the reinforcing element being in the form of a resilient frame connected to the textile based prosthesis and set back from the peripheral outer edge.

16. The kit of claim 14, wherein the resilient frame comprises a convex cranial segment extending from the medial end of the textile to the lateral end of the textile along the convex cranial edge, a caudal segment substantially extending from the medial end of the textile to the lateral end of the textile and caudally spaced with respect to the convex cranial segment, and a folding segment configured for joining a medial end of the convex cranial segment to a point located on the caudal segment while leaving a region of the medial end of the textile free of any frame.

17. The kit of claim 16, wherein the resilient frame is able to adopt an unstressed configuration, in which the textile is deployed, and a stressed configuration, in which the resilient frame is subjected to a transversal force directed towards the longitudinal axis, and the convex cranial segment, the caudal segment and the folding segment are substantially collected together and aligned on one folding direction, the textile forming thereby at least one fold along the folding direction.

18. The kit of claim 14, wherein the resilient frame is continuous.

19. The kit of claim 13, wherein the device comprises markings defining a ruler along the open longitudinal slit.

20. The kit of claim 13, wherein the tubular body of the device is made of a transparent material.
