A method of preoperative planning comprises creating a virtual model of a native patient tissue; placing a virtual device into a desired device orientation relative to the virtual model of the native patient tissue; specifying at least one structural change to the native patient tissue to facilitate placement of the virtual device in the desired device orientation; creating a virtual model of an altered patient tissue responsive to the specifying at least one structural change to the native patient tissue; and fabricating a tangible representation of a bone using the virtual model of the altered patient tissue.

System of preoperative planning and provision of patient-specific surgical aids

A patient tissue includes a primary patient tissue area and an anatomically differentiated bordering secondary patient tissue area. An apparatus is at least partially customized responsive to preoperative imaging of the patient tissue. Means are provided for mating with the primary patient tissue area in a preselected relative orientation. Means are provided for fixing a first landmark to the primary patient tissue area in at least one of a predetermined marking location and a predetermined marking trajectory. Means are provided for fixing a second landmark to the secondary patient tissue area in at least one of a predetermined marking location and a predetermined marking trajectory. A method of associating a plurality of landmarks with a patient tissue is also provided.

System and method for association of a guiding aid with a patient tissue

A guide for placing a landmark(s) in a patient tissue comprises a central portion defining at least one guiding bore configured to receive and guide a tool for placing the at least one landmark in the patient tissue. Extended portions project away from the central portion, each of the extended portions having respective lower base surfaces contoured to mate with the patient tissue, at least the respective lower base surfaces being customized as a function of preoperative imaging of the patient tissue, whereby the guide is specific to the patient.

A tool setting device includes a base body having longitudinally opposite base top and bottom surfaces laterally bounded by at least one base side surface. At least one setting aperture extends from the base top surface longitudinally downward at least partially through the base body. An elongate setting support slidably fits into a corresponding setting aperture. The setting support includes indicia and a tool engaging feature. A support holding feature is provided for maintaining a longitudinal position of the setting support with respect to the setting aperture. The tool engaging feature is positioned at a predetermined longitudinal distance above the base top surface. The predetermined longitudinal distance bears a direct relationship to the indicia. The tool engaging feature is maintained at the predetermined longitudinal distance through engagement of the setting support with the support holding feature. A method of transferring numerical setting information to a tool is also provided.

Tool setting device and method of transferring scaled setting information to a tool

A method for assisting a user with surgical implementation of a preoperative plan includes generating a physical native tissue model of a native patient tissue. The physical native tissue model includes at least one primary patient tissue area including a surface of interest, at least one secondary patient tissue area including no surfaces of interest, and a base surface for engaging a supporting structure. The physical native tissue model, as generated, includes at least one information feature providing clinically useful information to the user. The information feature is substantially separated from the surface of interest. An apparatus for assisting a user with surgical implementation of a preoperative plan is also provided.

A method of preoperative planning and provision of patient-specific surgical aids includes creating a virtual model of a native patient tissue. A virtual device is placed into a predetermined device orientation relative to the virtual model of the native patient tissue. At least one predetermined landmark orientation is specified for placement of at least one virtual landmark relative to the native patient tissue. A virtual patient-specific template containing the predetermined landmark orientation and having a landmark guiding feature is generated. At least one virtual patient-specific placement guide configured to interact simultaneously with at least one previously placed virtual landmark and the virtual device when the virtual device is in the predetermined device orientation is generated. A physical patient-specific template is created as a tangible representation of the virtual patient-specific template. A physical patient-specific placement guide is created as a tangible representation of the virtual patient-specific placement guide.
