Abstract

Protectors and methods of mounting protectors to features on implants within patients. The protectors attach to the features and provide protection to the patient by preventing or reducing injury that may be caused by the feature. The protectors may also be removable such that the feature can be exposed during future revision procedures. A variety of attachment methods may also be used to attach the protector to the feature. Insertion tools may be used for attaching the protectors to the features.

Claims

1. A device to protect a feature on an implant comprising a body having a closed end, a sidewall continuously extending outward from the end, and an opening formed by the sidewall and leading into a cavity formed by the end and the sidewall, the body constructed of an elastic material that is expandable from a first size with the opening smaller than the feature to a second size with the opening larger than the feature.

2. The device of claim 1, wherein the body includes a defined shape prior to attachment that corresponds to the feature.

3. The device of claim 1, further comprising an elastic rib attached to the body to apply tension and maintain the body attached to the feature.

4. The device of claim 1, further comprising elongated straps having opposing ends that connect together to attach the body to the feature.

5. The device of claim 1, wherein the body includes a non-corresponding shape prior to attachment that is different than the feature.

6. The device of claim 5, wherein the body includes a rolled configuration with at least one rolled section.

7. A device to protect a feature on an implant comprising a flexible, elastic cover that is expandable to fit onto the feature and apply a tension force to maintain attachment on the feature.

8. The device of claim 7, wherein the cover comprises a defined shape prior to attachment that corresponds to the feature.

9. The device of claim 7, wherein the cover includes a non-corresponding shape prior to attachment that is different than the feature.

10. The device of claim 7, wherein the device comprises an end and a sidewall that extends from the end and forms a cavity that receives the feature.

11. The device of claim 7, wherein the device is substantially cylindrical having a sidewall with first and second openings on opposite ends of the sidewall.

12. The device of claim 7, wherein the device includes a first color that is different than a color of the feature.

13. A device to protect a feature on an implant comprising a body having a closed end, a sidewall continuously extending outward from the end, and an opening formed by the sidewall and leading into a cavity formed by the end and the sidewall, the body constructed of a deformable material that deforms during attachment to the feature.

14. The device of claim 13, further comprising one or more ridges positioned on an inner side of the sidewall and extending into the cavity to form narrow sections within the cavity to maintain the body attached to the feature.

15. The device of claim 13, further comprising a slit positioned within the body and extending from the opening towards the end.

16. The device of claim 13, wherein the body is constructed of an elastic material.

17. A method of protecting a feature on an implant, the method comprising the steps of:

aligning a protector relative to the feature;

expanding the protector from a first size to a second size;

placing the protector onto the feature while in the second size; and

returning the protector from the second size towards the first size and applying a tension force to the feature to maintain the protector attached to the feature.

18. The method of claim 17, wherein the step of aligning the protector relative to the feature comprises positioning a closed end of the protector against a first surface of the protector.

19. The method of claim 17, further comprising changing a shape of the protector from a first shape prior to attachment to a second shape after attachment.

20. The method of claim 17, further comprising changing a shape of the protector to substantially match the feature.

21. The method of claim 17, further comprising aligning first and second openings relative to the feature and contacting a sidewall of the protector against the feature.

22. The method of claim 17, further comprising removing the protector from the feature after a period of time has expired.

23. The method of claim 17, further comprising inverting the orientation of the protector while placing the protector onto the feature.

24. A method of protecting a feature on an implant, the method comprising the steps of:

aligning a protector relative to the feature while the protector includes a first shape;

placing the protector onto the feature and deforming the protector from the first shape to a second shape that extends onto the feature; and

maintaining the protector on the feature.

25. The method of claim 24, comprising deforming the protector from the first shape that is non-corresponding to the feature to the second shape that corresponds to the feature.

26. The method of claim 24, further comprising removing the protector from the feature after a period of time.

27. The method of claim 24, further comprising inverting the protector during placement onto the feature.
