Abstract: In one aspect, a medical injector is provided herein having a body and an overcap releasably attached to the body configured to prevent mounting of a needle prior to mixing of components within the body. In a further aspect, a slidable collet may be provided useable to urge resilient members from an outward disrupted state inwardly to collectively define a needle mount. Advantageously, a medical injector is provided which ensures proper sequence in preparation of the device, particularly with respect to the step of allowing mounting of a medical needle to the device subsequent to preparation of the medicament to be administered.

Abstract: Intraocular lens (IOL) insertion apparatus and methods of use are provided and described herein. An example IOL insertion apparatus may include a handpiece body having a distal tip, a deployment chamber having an opening at a distal end of the handpiece body, and a deployment system disposed within the handpiece body. The deployment system can include a deployment carriage movable between proximal and distal positions within the handpiece body and a deployment plunger with a proximal end secured to the deployment carriage and a distal end to engage a folded IOL. The insertion apparatus may further include a damping feature protruding from a wall of the deployment chamber or a portion of the deployment system. The first damping feature may be positioned and arranged to increase a resistance to movement of the deployment system along a portion of a path traveled thereby between the proximal and distal positions.

Abstract: A medical injector is provided herein having a body; a reservoir containing first and second mixable components; a stopper; a plunger disposed in the body; a spring disposed to advance the plunger; a first releasable retainer for releasably retaining the plunger in a first state against force of the spring; a first trigger for causing the first releasable retainer to release the plunger; a second releasable retainer for releasably retaining the plunger in a second state against force of the spring; and, a second trigger for causing the second releasable retainer to release the plunger. The spring causes the plunger to advance so that the stopper traverses at least a predetermined extent of advancement thereby causing mixing of the first and second mixable components. Advantageously, with the subject invention, a medical injector is provided which allows for autoreconstitution with subsequent dose setting and autoplunger activation being activated by separate triggers.
