Abstract:
1. A medical implant expandable along a longitudinal axis and for supporting skeletal structures comprising: a first tubular member with a connection end extending along the longitudinal axis and an opposite skeletal interface end, the connection end of the first tubular member including an area with protrusions and an area without protrusions; a second tubular member with a connection end extending along the longitudinal axis configured to engage with the connection end of the first tubular member, the second tubular member having an opposite end opposite from the connection end of the second tubular member, the connection end of the second tubular member including an area with protrusions and an area without protrusions, wherein in a first angular relationship between the first and second tubular members, the area with protrusions of the first tubular member slides longitudinally along the area without protrusions of the second tubular member, and in a second angular relationship the protrusions of the first and second tubular members engage to prevent longitudinal sliding between the first and second tubular members; and a non-threaded interference mechanism configured to slide longitudinally between said first tubular member and said second tubular member to enter at least a portion of the area without protrusions of the first tubular member to prevent angular movement between the first tubular member and the second tubular member.
