Abstract
An inserter can include a needle, an actuation member, a plunger and/or assembly. The needle can define a lumen, and the plunger assembly can include a plunger and a plunger driver. The plunger can be at least partially disposed within the lumen of the needle, wherein the plunger is configured to advance a shunt through the lumen of the needle upon release. The plunger driver can be coupled to a proximal end portion of the plunger. The plunger driver elongates from a first length to a second length upon movement of the actuation member for advancing a distal end portion of the plunger from a first position to a second position relative to the lumen.
Claims15
An intraocular shunt inserter for treating glaucoma, comprising:
- a housing;
- a needle assembly at least partially disposed within the housing and comprising a needle and a needle driver coupled to a proximal end portion of the needle;
- a plunger assembly at least partially disposed within the housing and comprising a plunger and a plunger driver coupled to a proximal end portion of the plunger, the plunger being at least partially disposed within a lumen of the needle, the plunger being configured to advance a shunt through the lumen of the needle;
- and
- an actuation mechanism that is rotatable to change a length of at least one of the needle driver or the plunger driver to permit a clinician to adapt the inserter for a given surgical procedure, wherein rotation of the actuation mechanism displaces walls of an aperture defined in the needle driver or the plunger driver so as to change the length thereof.
An intraocular shunt inserter for treating glaucoma, comprising:
- a needle defining a lumen and a proximal end portion of the needle;
- a plunger assembly comprising a plunger at least partially disposed within the lumen of the needle, wherein the plunger is configured to advance a shunt through the lumen of the needle upon release;
- and
- a component driver comprising an actuation member and a body defining an aperture, wherein, upon displacement of walls of the aperture, the component driver elongates from a first length to a second length upon movement of the actuation member for changing a longitudinal relative position of at least one of a distal end portion of the plunger, when coupled to a proximal end portion of the plunger, or a distal end portion of the needle, when coupled to a proximal end portion of the needle.
