ABSTRACT:

FIELD OF THE INVENTION
Background of the Invention
In conventional techniques, hernial canal repair is generally carried out by suturing. However, that method of repair is not entirely satisfactory: given that the suture line is subject to a large amount of tension, there is a risk of tearing, which could then lead to recurrence of the hernia.
In order to mitigate that disadvantage, tension-free hernia repair techniques have been proposed.
In particular, a known technique is to position a sheet of synthetic prosthesis material, of knit or woven mesh, over the hernial canal, to reinforce or replace the weakened tissue. For example, in open surgical repair of an inguinal hernia, a sheet or patch of mesh may be used which is positioned on the inguinal ring, on the side remote from the peritoneum, this sheet being slit to allow the spermatic cord to pass, and the two tails of the patch are then wound around the spermatic cord. The barrier thus created makes it possible for the inguinal canal floor to regenerate.
Such a barrier-forming sheet may also be positioned by non-invasive surgery. A device using a trocar to deploy prosthesis sheets inside the abdominal cavity, on the peritoneum, is described in EP 0 544 485, for example.
Another tension-free repair technique, which may be used in combination with the above-mentioned technique, consists in obturating the hernial canal with a prosthesis device.
Usually a surgeon makes a device by rolling a patch cut from prosthesis material in order to obtain a cylinder of appropriate dimensions (i.e., such described by I. L. Lichtenstein and J. M. Shore, Simplified Repair of Fermoral and Recurrent Inguinal Hernias by a “Device” Technic. Amer. Journal of Surgery 1979; 138: 788-793).
Other shapes of prosthesis device are also used, such as rectangular devices, conical devices or collared devices, enabling them to be positioned relative to the hernial canal. The following may be consulted in that respect: “Prostheses in Abdominal Wall Hernia”, Robert Bendavid, RG Landes Company, Austin, pages 375-379, 380-382, 383-388, 389-398, 408-410, 411-412, 413-414, 446-449, and also U.S. Pat. Nos. 5,116,357 and 5,356,432.
Other known prostheses are constituted by cylindrical devices terminating at one end with prosthesis sheets for suturing by the surgeon to the non-weakened muscles on either side of the hernial canal to complement the obturation provided by the device. In that respect reference may advantageously be made to U.S. Pat. Nos. 5,141,515; 5,147,374; 5,219,077; and U.S. Pat. No. 5,249,682.
The object of the invention is to propose a prosthesis device which is simple in structure and simple to manipulate and which is also very effective.
SUMMARY OF THE INVENTION
The invention, therefore, provides a prosthetic device to repair a hernia defect which in one embodiment, comprising a canal insert having a proximal end and distal end; the proximal end being attached to a collar and the distal end being attached to and covered by a sheet.
In another embodiment of the present invention there is provided a prosthesis device to repair a hernia defect, the device comprising a canal insert for extending through said hernial canal, having a proximal end and a distal end; the proximal end being attached to a collar and the distal end of the canal insert being attached and covered by a pouch.
With such a structure, the canal insert, which is inserted in the hernia defect for obturation, is reinforced by a barrier-forming part which may either constitute a sheet or a pouch which provides very good resistance to intra-abdominal pressure because it is inserted on the inside of the hernial cavity and not on the outside.
Other characteristics and advantages of the invention can be seen from the following description. This description is intended as an illustration and is not limiting.
