Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
113 words
A surgically implantable percutaneous device for providing communication between an animal body exterior and an animal body interior the device comprising a rigid, flangeless tubular body of biologically compatible material, said tubular body having an exterior surface including a smooth upper portion which extends through the skin when implanted and a lower portion entirely below the surface of the skin when implanted, said lower portion including a porous tissue ingrowth media thereon for anchoring the device to the animal body, said tubular body including in the interior thereof an elastomeric septum member and means for holding said septum member in sealed relationship therein, said septum member defining an excutaneous cavity within the device.
Claim 2
Dependent Claim
113 words
A surgically implantable percutaneous device for providing communication between an animal body exterior and an animal body interior the device comprising a rigid, flangeless tubular body of biologically compatible material, said tubular body having an exterior surface including a smooth upper portion which extends through the skin when implanted and a lower portion entirely below the surface of the skin when implanted, said lower portion including a porous tissue ingrowth media thereon for anchoring the device to the animal body, said tubular body including in the interior thereof an elastomeric septum member and means for holding said septum member in sealed relationship therein, said septum member defining an excutaneous cavity within the device.
Claim 3
Dependent Claim
110 words
A surgically implantable percutaneous device for providing communication between an animal body exterior and an animal body interior the device comprising a rigid, flangeless tubular body of biologically compatible material, said tubular body having an exterior surface including a smooth upper portion which extends through the skin when implanted and a lower portion entirely below the surface of the skin when implanted, said lower portion including a porous tissue ingrowth media thereon for anchoring the device to the animal body, a flexible tubular catheter member in engagement with said lower portion with the tissue ingrowth media extending over the joint defined by said lower portion and said tubular catheter member.
Claim 4
Dependent Claim
110 words
A surgically implantable percutaneous device for providing communication between an animal body exterior and an animal body interior the device comprising a rigid, flangeless tubular body of biologically compatible material, said tubular body having an exterior surface including a smooth upper portion which extends through the skin when implanted and a lower portion entirely below the surface of the skin when implanted, said lower portion including a porous tissue ingrowth media thereon for anchoring the device to the animal body, a flexible tubular catheter member in engagement with said lower portion with the tissue ingrowth media extending over the joint defined by said lower portion and said tubular catheter member.
Claim 5
Dependent Claim
23 words
A device as in claim 2 wherein said catheter member includes a portion thereof having a plurality of perforations through the sides thereof.
