Abstract

A protective cap having finger grips, a window, and port. The protective cap may also have one or more clips (or snaps), one or more relief slots, and/or one or more guides. Protective cap 200 may also have a fill indicator and/or a material relief. An insertion system having a handpiece, a pushrod assembly, a cartridge, and a cap with a window and a port. The cap is configured and dimensioned to couple with the distal end of the cartridge. The insertion system may also have a pushrod with a plunger having a marker configured and dimensioned to indicate axially translation of the pushrod assembly within the handpiece.

First claim

The invention claimed is:

1. An insertion system, comprising:
a handpiece comprising a longitudinal axis, a distal end, a proximal end, and a port;
a pushrod assembly comprising a distal end and a proximal end;
wherein the pushrod assembly comprises a pushrod and a plunger;

wherein the pushrod assembly couples with the handpiece along the longitudinal axis;
wherein the pushrod is coupled with the plunger and the pushrod is located on the distal end of the pushrod assembly and the plunger is located on the proximal end of the pushrod assembly;
wherein the pushrod comprises a bifurcated tip defining a top jaw and a bottom jaw, with at least one cutout portion;
a cartridge comprising a delivery tube at a distal end;
wherein the cartridge is configured and dimensioned to couple with the distal end of the handpiece;
a cap comprising a port;
wherein the cap is configured and dimensioned to couple with the distal end of the cartridge; and
wherein the port of the cap mates with the port in the handpiece, and wherein the port of the cap is larger than the port in the handpiece to provide a funnel feature into the handpiece.

2. The insertion system of claim 1 , wherein the cartridge further comprises one or more wings and the cap further comprises one or more clips, wherein the one or more clips are configured and dimensioned to couple with the one or more wings.

3. The insertion system of claim 1 , wherein the cap further comprises an internal bevel inside the cap at a distal end, wherein the internal bevel is configured and dimensioned to couple with a bevel at a distal end of the delivery tube.

4. The insertion system of claim 1 , wherein the cap further comprises at least two finger grips along at least a portion of a longitudinal axis of the cap and wherein the finger grips are located on opposite sides of the cap.

5. The insertion system of claim 1 , wherein the cap comprises a window.

6. The insertion system of claim 5 , wherein the window is located on a bottom of the cap and wherein the window runs along at least a portion of a longitudinal axis of the cap.

7. The insertion system of claim 1 , wherein the port is configured and dimensioned to couple with a lumen at a distal end of an insertion system to enable insertion of a fluid into the lumen at the distal end of the insertion system.

8. The insertion system of claim 1 , wherein a distal end of the cap comprises a material relief to prevent distortion of a tip at the distal end of the cap during manufacturing of the cap.

9. The insertion system of claim 1 , wherein one or more internal walls of the cap comprise one or more internal guides that run along at least a portion of a longitudinal axis of the cap, wherein the one or more internal guides are configured and dimensioned to couple with features on an outer portion of the insertion device.

10. The insertion system of claim 9 , wherein the cap comprises two substantially parallel internal guides.

11. The insertion system of claim 1 , wherein the pushrod further defines an additional cutout portion on an opposite side of the pushrod relative to the cutout portion.

12. The insertion system of claim 1 , wherein the top jaw comprises a lip that protrudes from an upper portion of the top jaw.
