Abstract:
A shaver blade assembly for resecting tissue comprising:an elongated outer tubular member having an axis, a proximal end, a distal end, a laterally facing and end facing cutting window situated at said distal end, and further comprising a first transverse planar end wall at its distal end, said end wall having a distally facing outer surface, a proximally facing inner surface and a first transverse edge on its inner surface, said first transverse planar end wall joined with said distal end of said outer tubular member over a predetermined arcuate length of greater than 180.degree. about the axis of said tubular member; andan elongated inner tubular member rotatably situated within said tubular outer member, said tubular inner member having a proximal end, a distal end, a laterally facing and end facing cutting window situated at said distal end, and further comprising a second transverse planar end wall at its distal end, said end wall having a distally facing outer surface, a proximally facing inner surface and a second transverse edge on its outer surface, said second transverse planar end wall joined with said distal end of said inner tubular member over a predetermined arcuate length of greater than 180.degree. about the axis of said tubular member, said second transverse edge of said inner member adapted to cooperate with said first transverse edge of said outer member to resect tissue presented therebetween upon relative rotation of said inner and outer tubular members.
