Abstract:
1. An expandable medical implant for supporting skeletal structures comprising: a first tubular member having a generally cylindrical configuration with a first connection end and an opposite first skeletal interface end and a first longitudinal axis extending between the first connection end and the first skeletal interface; a second tubular member having a generally cylindrical configuration with a second connection end configured to engage with the first connection end of the first tubular member, the second tubular member having an opposite second skeletal interface end and a second longitudinal axis extending between the second connection end and the second skeletal interface, an elongated slot extending through the second tubular member in a direction parallel to the second longitudinal axis; and a key pin non-threadingly fixedly secured to the first tubular member and extending outward from an outer surface of the first tubular member, the key pin positioned within the slot extending through the second tubular member such that engagement of the key pin and the slot guides translation between the first tubular member and the second tubular member along a desired path in a direction parallel to the first and second longitudinal axes without relative rotation of the first and second tubular members.
