Abstract

A kit for deploying a bone implant at a surgical site is provided. The kit comprises a first sleeve having an interior surface that defines a channel, and a second sleeve having an outer surface and an inner surface. The inner surface of the second sleeve defines an inner channel. The outer surface of the second sleeve is configured to slidably engage the interior surface of the channel of the first sleeve. A bone implant is also provided comprising a mesh material. The mesh material is disposed in a portion of the channel of the first sleeve or disposed in a portion of the inner channel of the second sleeve or disposed in both the portion of the channel of the first sleeve and the portion of the inner channel of the second sleeve.

First claim

What is claimed is:

1. A kit for deploying a bone implant at a surgical site, the kit comprising:
a first sleeve having an interior surface that defines a channel, the first sleeve having a tapered distal end tapering toward a central axis of the first sleeve;
a second sleeve having an outer surface and an inner surface, the inner surface of the second sleeve defining an inner channel, the outer surface of the second sleeve configured to slidably engage the interior surface of the channel of the first sleeve, the second sleeve also having a tapered distal end tapering toward a central axis of the first sleeve, the distal end including a capturing mechanism configured to fasten to the bone implant such that the second sleeve engages the bone implant such that the tapered distal end is configured to deploy the bone implant directly to the surgical site; and
the bone implant comprises a mesh material partially enclosing a bone material before the bone implant deploys, the mesh material disposed in a portion of the channel of the first sleeve or disposed in a portion of the inner channel of the second sleeve or disposed in both the portion of the channel of the first sleeve and the portion of the inner channel of the second sleeve such that sliding the outer surface of the second sleeve deploys the bone implant at the surgical site, the mesh being configured to be held and compressed inside the first sleeve and the mesh comprising an attachment mechanism comprising a grommet allowing a screw to affix the mesh at the surgical site so that the bone material does not migrate away from the surgical site after the mesh is deployed away from the first sleeve and the second sleeve, wherein the mesh is attached to the outer surface at the distal end of the second sleeve and the mesh is perpendicular to a longitudinal axis of the second sleeve with the capturing mechanism comprising hooks, anchors, buttons, clips, snaps, friction fittings, compressive fittings, expanding rivets, staples, nails, posts, connectors, or a combination thereof, the capture mechanism located at the distal end of the second sleeve.

2. The kit according to claim 1 , wherein the first sleeve and the second sleeve are dilators; and the first sleeve has a diameter that is greater than a diameter of the second sleeve, and the bone implant has a diameter that is greater than the diameter of the second sleeve.

3. The kit according to claim 1 , wherein the second sleeve comprises an engagement member disposed on the outer surface of the second sleeve and is configured for engagement with the channel of the first sleeve.

4. The kit according to claim 3 , wherein the engagement member is made from one or more metals, plastics, polymers, or a combination thereof.

5. The kit according to claim 1 , wherein the mesh material is made from resorbable natural or synthetic polymers comprising at least one of poly(lactic acid) (PLA), poly(glycolic acid) (PGA), poly(lactic-co-glycolic acid) (PLGA), silk, or a combination thereof.

6. The kit according to claim 1 , wherein the kit further comprises fastening elements comprising resorbable screws, resorbable tacks, adhesives, or a combination thereof.
