Abstract
A reinforced surgical membrane for supporting bone growth by shielding a bone cavity from soft tissue in-growth comprises are a reinforcing layer (2) between a first membrane layer and a second membrane layer (4). The reinforcing layer (2) has defined therein an array of holes (3) which may connect the first and second membrane layers.
Claims15
A reinforced surgical membrane for supporting bone growth by shielding a bone cavity from soft tissue ingrowth, the membrane comprising a reinforcing layer between a first membrane layer and a second membrane layer, wherein the reinforcing layer has defined therein an array of holes and wherein a material of the first membrane layer has a different density and/or thickness to a material of the second membrane layer prior to implantation.
A reinforced surgical membrane for supporting bone growth by shielding a bone cavity from soft tissue ingrowth, the membrane comprising a reinforcing layer between a first membrane layer and a second membrane layer, wherein the reinforcing layer has defined therein an array of holes and wherein the first membrane layer has a different density and/or thickness to the second membrane layer, wherein the array comprises at least one blind hole capable of containing a pharmaceutically active substance.
A reinforced surgical membrane for supporting bone growth by shielding a bone cavity from soft tissue ingrowth, the membrane comprising a reinforcing layer between a first membrane layer and a second membrane layer, the first membrane layer comprising a first material and the second membrane layer comprising a second material that is different to the first material, wherein the reinforcing layer has defined therein an array of holes and wherein the first material of the first membrane layer has a different density and/or thickness to the second material of the second membrane layer.
