Abstract
An iris-expanding device injector assembly is described. The iris-expanding device injector assembly has a handle, a slider and/or button coupled with the handle and configured to slide with respect to the handle, a cannula coupled with the handle, the cannula configured to slide in to and out from a holder containing an iris-expanding device, and a hook housed within the cannula.
Claims20
An iris-expanding device injector assembly comprising:
- a handle having a first end, a second end, an interior, and a length;
- a slider coupled with the handle and configured to slide with respect to the handle;
- a cannula coupled with the first end of the handle and having an open end spaced from the first end of the handle, the cannula configured to slide in to and out from a holder containing an iris-expanding device;
- a hook connected to the slider, the hook configured to:
- extend into the holder in response to sliding the slider in a first direction;
- grasp the iris-expanding device contained in the holder, wherein the iris-expanding device is contained in the holder in an expanded configuration;
- and
- pull the iris-expanding device into the open end of the cannula in response to sliding the slider in a second direction,
- wherein pulling the iris-expanding device into the open end of the cannula causes the iris-expanding device to transition from the expanded configuration to a collapsed configuration in the cannula.

An iris-expanding ring injector comprising:
- a handle having a distal end, a proximal end, an interior;
- a button coupled to the handle and configured to move between a first position and a second position;
- a cannula having:
- a proximal end coupled to the distal end of the handle, and
- an open distal end;
- a hook housed within the cannula when the button is in the first position,
- wherein, when the button is moved to the second position, the hook extends past the open distal end of the cannula, and is configured to grasp an iris-expanding ring in an expanded configuration, and
- wherein, when the button is moved to the first position, the iris-expanding ring grasped by the hook is transitioned from the expanded configuration into a collapsed configuration in the cannula.

An iris-expanding device injector assembly comprising:
- a handle having a distal end, a proximal end, an interior, and a length;
- a slider configured to move between the distal end and the proximal end of the handle;
- a cannula having:
- a proximal end coupled to the distal end of the handle, and
- an open distal end;
- an arm having a contacting end that contacts an iris-expanding device, wherein the arm and the contacting end are housed within the cannula when the slider is in a first position towards the proximal end of the handle,
- wherein, when the arm and the contacting end are housed within the cannula, the iris-expanding device is in a collapsed configuration in the cannula, and
- wherein, when the slider is moved to a second position towards the distal end of the handle, the contacting end of the arm extends beyond the open distal end of the cannula and transfers the iris-expanding device in the collapsed configuration beyond the open distal end of the cannula into an expanded configuration.
