Estimating the term…
A cannula has a body with a proximal end and a distal end and a tip on the distal end. The tip has an outer wall defining a lumen opening at the end of the tip and extending to the proximal end of the cannula. The tip further comprises one or more ribs extending into the lumen to support the outer wall from kinking when the cannula is flexed. The outer wall has a inner surface defining the lumen and a plurality of non-circular apertures formed in the tip extending into the lumen. The apertures having a major axis and a minor axis. The major axis aligned in relation to a circumference of the outer wall to prevent puckering or buckling when the tip is bent. This alignment is also designed to support the outer wall from kinking when the tip is bent.
A cannula, comprising:
A cannula, comprising:
A cannula having a body, the body having a proximal end, a distal end and a tip on the distal end, an outer wall defining a lumen in the body between the tip and the proximal end, a plurality of ribs formed on the tip extending into the lumen, the ribs having a top spaced from the outer wall, the body, a plurality of non-circular shaped apertures punched in the interconnecting link in fluid communication with the lumen whereby the cannula is resistant to kinking when flexed during use.
