Abstract

This invention discloses insertor devices that employ a flexible, deformable sleeve to house an implant. In one embodiment, a device is described that employs squeezing blades to advance an implant through the flexible sleeve into a passageway, tissue or cavity of the body. The invention further relates to holders for the sleeve to facilitate loading of an implant into the sleeve. In a preferred embodiment, the device is an insertor for a foldable lens and in particular the device is an insertor for the introduction of an intraocular lens into the eye. Methods for loading the devices of this invention with an implant, methods for making the sleeves of this invention and methods for use are discussed.

Claims

1. A device for introducing an implant into the body comprising:

a flexible compressible sleeve wherein the sleeve comprises a first opening and a second opening and a lumen extending through the sleeve, wherein the sleeve is prepared from a non-opaque material and wherein the width of the first opening is larger than the width of the second opening; and

a hand-piece capable of mobilizing the implant and immobilizing the sleeve, wherein the hand-piece comprises;

at least one blade to mobilize the implant by squeezing the sleeve; and

a pressure fit element to immobilize the sleeve in the hand-piece, wherein the pressure fit element is a collet or a screw.

2. The device of claim 1 wherein the implant is a lens.

3. The device of claim 2 wherein the implant is an intraocular lens.

4. The device of claim 1, wherein the sleeve is provided with a buffer.

5. A device for introducing an implant into the body comprising:

a flexible compressible sleeve wherein the sleeve comprises a first opening and a second opening and a lumen extending through the sleeve, wherein the sleeve is prepared from a non-opaque material and wherein the width of the first opening is larger than the width of the second opening; and

a hand-piece capable of mobilizing the implant and immobilizing the sleeve, wherein the hand-piece further comprises a collet or a screw to immobilize the sleeve in the hand-piece.

6. The device of claim 5 wherein the implant is a lens.

7. The device of claim 5 wherein the implant is an intraocular lens.

8. The device of claim 5 wherein the hand-piece comprises a pushrod positioned within the sleeve to mobilize the implant.

9. The device of claim 8 wherein the push rod has a rounded tip.

10. The device of claim 5, wherein the sleeve is provided with a buffer.

11. A device for introducing an implant into the body comprising:

a flexible compressible sleeve wherein the sleeve comprises a first opening and a second opening and a lumen extending through the sleeve, wherein the sleeve is prepared from a non-opaque material and wherein the width of the first opening is larger than the width of the second opening; and

a hand-piece capable of mobilizing the implant and immobilizing the sleeve, wherein the hand-piece comprises;

at least one blade to mobilize the implant by squeezing the sleeve; and

a collet or a screw to immobilize the sleeve in the hand-piece.
