Abstract
A half pipe cannula has a first portion and a second portion. The first portion, which includes a proximal end and an elongated tab along the length of the first portion, can be formed from a first material with a selected rigidity. The second portion, which includes a proximal end, a cannulated passage, and a distal end, can be formed from a second material with a selected flexibility. The second portion of the half pipe cannula partially or fully overlaps the elongated tab of the first portion of the half pipe cannula. The second portion of the half pipe cannula has surface features such as a thread or bumper feature. Each portion of the half pipe cannula may have one or more flanges on either end or both ends. The second portion of the half pipe cannula can be made of a flexible material such as thermoplastic elastomer.
