Abstract

An injectable securement device includes one or more sutures and a bolster housed inside an elongate element, and may be part of a system that also includes one or more fastening elements and an elongate element. Injecting a suture tie/knot can be accomplished outside the eye without the need for performing the action of tying within the eye.

First claim

I claim:

1. A system for grasping an intraocular object comprising:
an injectable securement device comprising a suture forming a securement through and around a bolster, wherein applying tension to the suture cinches a closed loop of the securement against the bolster to grasp an intraocular object extending through the loop and secure the intraocular object against the bolster, wherein the bolster is comprised of a material that is resiliently deformable such that the suture deforms the bolster when the suture is pulled tight around the bolster to prevent unraveling of the loop and slipping of the securement, and further wherein the suture is threaded through the bolster along two different axes of the bolster; and
an elongate element having a lumen extending therethrough, the elongate element comprising an actuator mechanism, and the elongate member being configured to pierce tissue with a distal end, wherein the suture is threaded through the elongate element, and wherein the injectable securement device is configured to be deployed from the distal end by the actuator mechanism.

2. The system of claim 1 , wherein the elongate element is a cannula.

3. The system of claim 1 , wherein the bolster is comprised of a dissolvable material.

4. The system of claim 1 , wherein the actuator mechanism is at least one of pneumatically driven and hydraulically driven, wherein the injectable securement device is frictionally anchored within the lumen so as to be deployed from the distal end by pressure in the form of a gas, fluid, or viscoelastic material.

5. The system of claim 1 , wherein the actuator mechanism comprises at least one of a rod and a plunger, wherein the injectable securement device is configured to be deployed from the distal end using the rod or the plunger.
