Abstract
A hybrid cannula may comprise a first portion formed from a first material, a second portion formed from a second material overmolded to the first portion, a third portion formed from a third material and a fourth portion formed from a fourth material overmolded to the third material. The third portion is coupled to the first portion. The first portion may prevent the proximal end of the hybrid cannula from being pushed through a portal. The second portion may include a membrane and the fourth portion may include a dam, the dam defining interior spaces thereof between the proximal and distal ends of the hybrid cannula. The membrane and/or dam may prevent liquid from projecting during insertion or removal of instruments. The distal end of the hybrid cannula may comprise a variety of features.
