Abstract
A surgical implant suitable for treatment of hernias is provided. The implant comprises a mesh having a residual maximum mass density of 50 g/m3. The mesh comprises strands forming spaces and the strands comprise filaments forming pores. The spaces and pores are sized to minimise foreign body mass for implantation and to encourage integration of the implant. The mesh may be delivered using Dual Phase Technology™ for ease of handling, cutting and placement. The Dual Phase Technology™ may include encapsulation or coating with hydrogel.
Claims64
A surgical implant suitable for treatment of hernias, the implant comprising a mesh comprising strands having a maximum residual mass density of 50 g/m2.
A surgical implant as claimed in any preceding claim wherein strands are formed from at least two filaments.
A surgical implant as claimed in any preceding claim wherein the strands are spaced apart to form major spaces of 1 to 10 mm.
A surgical implant as claimed in any preceding claim wherein the strands have a diameter of less than 600 μm.
A surgical implant as claimed in any preceding claim wherein the strands are arranged to form a warp knit diamond or hexagonal net mesh.
A surgical implant as claimed in any preceding claim wherein the strands are arranged to form a net mesh which has isotropic or near isotropic tensile strength and elasticity.
A surgical implant as claimed in any preceding claim wherein a monofilament or at least two filaments are interwoven/knitted such that the strands of the mesh comprise pores.
A surgical implant as claimed in any preceding claim wherein the pores in the strands are of between 50 to 200 μm in diameter.
A surgical implant as claimed in any preceding claim further comprising rings of material comprising pores of between 50 to 200 μm adhered to on the strands of the mesh to provide pores.
A surgical implant as claimed in any preceding claim wherein the pores in the strands are of between 50 to 75 μm in diameter.
A surgical implant as claimed in any preceding claim wherein the filaments of the mesh comprise a plastics material.
A surgical implant as claimed in any preceding claim wherein the filaments of the mesh comprise a synthetic material.
A surgical implant as claimed in any preceding claim wherein the filaments of the mesh comprise an absorbable material.
A surgical implant as claimed in any preceding claim wherein the implant has an absorbable coating which degrades within 48 hours.
A surgical implant as claimed in any preceding claim comprising a backing strip wherein the backing strip is releasably attachable to the mesh.
A surgical implant as claimed in any preceding claim wherein the strands of the mesh are comprised of bicomponent microfibres.
A surgical implant as claimed in any preceding claim wherein the surgical implant comprises material that has memory.
A surgical implant as claimed in any preceding claim wherein the implant has a generally curved perimeter.
A surgical implant as claimed in any preceding claim wherein the surgical implant is of width between 1 cm to 10 cm and of length between 1 cm to 10 cm.
A surgical implant as claimed in any preceding claim wherein the implant is any one of round, circular, oval, ovoid eliptical or truncated eliptical or some similar shape.
A surgical implant as claimed in any preceding claim wherein the mesh can be cut to any desired shape.
A surgical implant as claimed in any preceding claim wherein the mesh has at least one circumferential member which extends, in use, along at least part of the perimeter of the implant to provide a substantially smooth edge.
A surgical implant as claimed in any preceding claim wherein the mesh can be glued in place using a biocompatible glue.
A surgical implant as claimed in any preceding claim comprising at least one capsule containing biocompatable glue for securing the implant in place.
A minimally invasive method of treating uterovaginal prolapse, the method comprising the steps;
- making a 1-2 cm length incision in the vaginal wall close to the opening of the vaginal cavity and,
- making a subcutaneous cut, through the incision, over and surrounding the area of the prolapse, which cut is substantially parallel to the vaginal wall;
- and
- inserting a mesh according to the present invention, through the incision, into the space defined by the cut.
