1. A retrograde resection apparatus for resecting tissue, comprising:
a cutting blade having a body defining a first surface a second surface opposite to said first surface, and including at least one cutting feature provided on said second surface;
a radial slot extending through said first and second surfaces and defined through at least a radial portion of said body;
a recess defined in said body and located in at least a portion of said radial slot;
a shaft having a distal end and a proximal end, wherein a portion of said distal end is received in said recess to allow said cutting blade rotatably driven by said shaft;
a biasing device configured to bias said shaft against said cutting blade; and
wherein the cutting blade is configured to cut the tissue when the shaft is rotatably driven proximally in a retrograde direction towards the proximal end.
