A pre-slit injection site includes a housing with a flow path therethrough. A first end of the housing carries a pre-slit septum. A blunt cannula, usable with the injection site, carries a locking member. When the pre-slit injection site slidably receives the blunt cannula the locking member latches to the injection site forming a mechanically coupled unit.

A surgical fastening clip of a shape memory alloy which applies a first clamping force to a site when the alloy is in its martensitic condition and a second clamping force to the site when the alloy heats due to surrounding tissue such that the alloy transforms to its austenitic condition. The second clamping force is greater than the first clamping force and prevents the clip from slipping or fal...
