Claims22
A trocar skirt defining a proximal end and a distal end, comprising:
- a mounting ring disposed adjacent the proximal end of the trocar skirt;
- a multiplicity of rigid strips extending distally from the mounting ring to define the distal end of the trocar skirt;
- and
- a multiplicity of elastomeric strips alternately disposed between the multiplicity of rigid strips to support the rigid strips, the multiplicity of elastomeric strips extending distally from the mounting ring to the distal end of the trocar skirt,
- wherein the multiplicity of rigid strips and the multiplicity of elastomeric strips are arranged in an annular configuration to define a cannula port having an aperture at the proximal end of the trocar skirt and having an aperture at the distal end of the trocar skirt and a throat area between the proximal end and the distal end,
- the multiplicity of rigid strips and the multiplicity of elastomeric strips each defining at least a partial taper between the proximal end of the trocar skirt and the throat area and at least a partial taper between the throat area and the distal end of the trocar skirt.
