CANNULAS WITH NON-CIRCULAR CROSS-SECTIONS, SYSTEMS, AND METHODS

A cannula includes a tube having a central passage extending between a proximal end and a distal end of the tube along a longitudinal axis of the tube. A first cross section of the passage taken at or adjacent the distal end of the tube and in a plane normal to the longitudinal axis has a first cros...

Zusammenfassung:A cannula includes a tube having a central passage extending between a proximal end and a distal end of the tube along a longitudinal axis of the tube. A first cross section of the passage taken at or adjacent the distal end of the tube and in a plane normal to the longitudinal axis has a first cross-sectional shape, the first cross-sectional shape being non-circular. A second cross section of the passage taken through a portion of the tube proximal to the distal end of the tube and in a plane normal to the longitudinal axis has a second cross-sectional shape. The first cross-sectional shape is different from the second cross-sectional shape. Systems related to cannulas and tools for insertion through cannulas.
