Abstract
A generic bone implant, or set of standardized implants, is created based on using a guide device to develop an axis normal to an articular surface of bone and collecting only one or two data points. A generic cutting tool is used to cut the bone to a point where a generic implant can be used. Several improved tools relating to the procedure for using such an implant, as well as methods for using implants consistent with the invention are further described, including: single-axis and biaxial drill guide tools and methods, generic single-axis implant methods and devices, generic biaxial implant methods and devices, tools and methods for holding or delivering an implant, removal or revision tools and methods, digital measuring systems and methods, and set of measuring gauges for determining the appropriate implant dimensions.

7. A device for mapping a portion of an articular surface of bone, said device comprising:
-
a handpiece;
an inner shaft running along the length of and disposed within said handpiece, said inner shaft comprising a mating feature for mating with a fixed element located substantially normal with respect to an articular surface;
a contact tip slidably and rotatably disposed about said inner shaft;
a rotary measuring element coupled to and rotating with said contact tip; and
a linear measuring element nested concentrically and coaxially to said rotary measuring element, and coupled to and moving linearly with said contact tip. - View Dependent Claims (8, 9, 10, 11)
