Problems solved by technology

[0002] Previously, repairs have been accomplished with various simple closures, but such closures are a "tightening" repair method and lead to high recurrence rates
A flat, surgically acceptable mesh material is used to seal the defect, but the raised portion of the disease is preserved and, in some cases, recurrence rates remain high
While repairs under the muscle wall yield better results, there is a risk of intra-prosthetic adhesions or a considerable incision

Embodiment Construction

[0014] An embodiment of the present invention is described and illustrated with reference to the accompanying drawings.

[0015] Referring to the accompanying drawings, an implantable prosthesis is mainly used for the repair of defects in the muscular wall such as hernias, especially for the repair of umbilical or paraumbilical hernias and possibly ventral or semilunar hernias. The prosthesis comprises an upper sheet 1 made of a surgically compatible mesh material or PTFE material, and a lower bar 2, which is made of a surgically compatible mesh material or PTFE material. 3, such as a composite polypropylene mesh material or PTFE, the button 2 is connected to the upper sheet at intervals through a bridge portion 5. The innermost surface of the button 2 contains a visceral adhesion inhibiting material 4 made of PTFE or equivalent.

[0016] The upper sheet 1 and the lower button 2 are connected by a bridge portion 5, and this may comprise a separate connecting portion, but it i...

Abstract

An implantable prosthesis for repairing a muscular wall defect such as a hernia, especially for repairing an umbilical or paraumbilical hernia and possibly a ventral or meniscal hernia, the implantable prosthesis comprising: a surgically associated An upper sheet (1) of capacitive mesh or polytetrafluoroethylene material and a lower button (2) of a surgically compatible mesh or polytetrafluoroethylene material (3), such as a composite polypropylene mesh / PTFE. The lower buttons are connected to the upper sheet by bridges (5), but spaced apart. The innermost surface of the button (2) comprises a visceral adhesion inhibiting material (4) of polytetrafluoroethylene or equivalent material.

Description

technical field [0001] The present invention relates to an implantable device, and mainly relates to a prosthesis for repairing umbilical or paraumbilical herniation, that is, the hernia bulge occurs at or near the umbilicus. The device can also be used in other sites, such as small ventral hernias, or semilunar hernias (Spigelean herniae). These hernias are usually small but can enlarge significantly. Background technique [0002] Previously, repairs have been accomplished with various simple closures, but such closures are a "tightening" repair and lead to high recurrence rates. A flat, surgically acceptable mesh material is used to seal the defect, but the raised portion of the disease is preserved and, in some cases, recurrence rates remain high. While repairs under the muscle wall yield better results, there is a risk of intra-prosthetic adhesions or a considerable incision. [0003] For the repair of umbilical or paraumbilical hernias, professional repair mesh mater...
