Abstract
A medical or orthopedic implant, system and method for making the implant having areas that are designed to optimize compressive stress processing by, for example, laser shock peening. The implant is designed by identifying stress areas as processing zones. The processing zones are machined, processed or adapted to have a desired shape or configuration to optimize compression. The processed zones or areas are compressive stressed processed to have a higher density at zones or areas compared to areas that are not compressive stress processed. The implant is finished processed and sterilized and ready for use in the patient.
Claims83
An orthopedic implant comprising:
- an implant body;
- a first portion of said implant body have a first density;
- and
- a second portion of said implant body has a second density;
- wherein said first portion is compressed so that said first portion comprises a biomechanical stress concentration or density that is higher than a biomechanical stress concentration or density in said second portion when said orthopedic implant is subject to biomechanical forces after being situated on a skeletal structure.
A method for processing an orthopedic implant, said method comprising the steps of:
- providing an implant body;
- determining areas of stress in said orthopedic implant during use in a patient,
- using said areas of stress to determine at least one predetermined zone in said implant body to facilitate or substantially optimize compressive stressing of said at least one predetermined zone;
- and
- compressive stress processing said at least one predetermined zone of said implant body such that after said compressive stress processing step, said at least one predetermined zone comprises a biomechanical stress concentration or first density at said at least one predetermined zone that is generally higher than a biomechanical stress concentration or second density in other areas of said implant body when said orthopedic implant is subject to biomechanical forces after being situated on a skeletal structure.
A system for making an implant, said system comprising:
- a holder for holding the implant;
- a design station for determining areas of stress in said implant during use in a patient and for creating a predetermined design including at least one predetermined zone in said implant to facilitate or substantially optimize compression of said at least one predetermined zone;
- a processing station for processing said implant at said at least one predetermined zone to facilitate or substantially optimize said compression of said at least one predetermined zone in response to said predetermined design;
- and
- a compression station for compressing said at least one predetermined zone of said implant.
