Abstract

The variable or adjustable depth medical implants in this application are capable of depth adjustment prior to implantation. The variable depth implants permit a single implant to provide multiple footprint configurations, allowing a surgeon footprint adjustability in the operating room. The implants can comprise a metallic lattice designed for specific physical properties, such as an elastic modulus. In some examples, the main body of the implant is taller than the adjustable portion of the implant (also referred to as the second implant body) so that the physical properties of the main body of the implant are controlling at the implant site. In some embodiments, the variable implant is constructed in an additive process as a single unit.

Dependent claims

A medical implant comprising:

a main implant portion comprising:
a main implant body;
an attachment extension coupled to an interior surface of the main implant body;
and
a plurality of attachment extension ridges disposed on a portion of each lateral side of an internal surface of the attachment extension;
and
a second implant portion comprising:
a second implant body;
an attachment receiver coupled to the second implant body;
and
a plurality of attachment receiver ridges disposed on an interior surface of the attachment receiver;
wherein the attachment extension coupled to the main implant body is configured to slide into the attachment receiver coupled to the second implant body such that the plurality of attachment extension ridges engage at least one of the plurality of the attachment receiver ridges to couple the main implant portion to the second implant portion.
