Abstract
A sleeve assembly is provided comprising an inner tubular member and at least one outer sleeve that receives at least a portion of the inner tubular member. The outer sleeve may longitudinally telescope with the inner tubular member to move between a non-expanded position and at least one expanded position. In some embodiments, the inner tubular member comprises a first locking component and the at least one outer sleeve comprises a second locking component that interlocks with the first locking component to secure the outer sleeve in the non-expanded position and/or at least one expanded position. Related methods for making a sleeve assembly are also provided.

A sleeve assembly comprising:
- an inner tubular member comprising a first locking component;
- at least one outer sleeve that telescopically engages the inner tubular member in a non-expanded position and at least one expanded position, the at least one outer sleeve comprising a second locking component that interlocks with the first locking component;
- and
- wherein the first and second locking components interlock to secure the at least one outer sleeve in at least one of the non-expanded position and the at least one expanded position, wherein one of the first and second locking components comprises a projection and the other one of the first and second locking components comprises a recess, the projection being received into the recess, and wherein the recess extends radially partially though the inner tubular member or at least one outer sleeve.
A method for making a sleeve assembly, the method comprising:
- providing an inner tubular member comprising a first locking component;
- and
- providing at least one outer sleeve that telescopically engages the inner tubular member in a non-expanded position and at least one expanded position, the at least one outer sleeve comprising a second locking component that interlocks with the first locking component;
- wherein one of the first and second locking components comprises a projection and the other one of the first and second locking components comprises a recess, the projection being receivable into the recess, and wherein the recess extends radially partially through the inner tubular member or the at least one outer sleeve.
A sleeve assembly comprising:
- an inner tubular member comprising a first locking component;
- at least one outer sleeve that telescopically engages the inner tubular member in a non-expanded position and at least one expanded position, the at least one outer sleeve comprising a second locking component that interlocks with the first locking component;
- wherein the first and second locking components interlock to secure the at least one outer sleeve in at least one of the non-expanded position and the at least one expanded position;
- wherein one of the first and second locking components comprises a projection and the other one of the first and second locking components comprises a recess, the projection being received into the recess;
- and
- wherein the recess further comprises:
- a first niche, a second niche, and a third niche that each receive the projection therein to interlock the first and second locking components;
- a first longitudinal channel interconnecting the first niche and the second niche, the first longitudinal channel rotationally offset from the first niche and the second niche;
- a second longitudinal channel interconnecting the second niche and the third niche, the second longitudinal channel rotationally offset from the second niche and the third niche;
- and
- wherein longitudinal movement of the at least one outer sleeve with respect to the inner tubular member slides the projection through the first and second longitudinal channels and wherein rotation of the at least one outer sleeve with respect to the inner tubular member displaces the projection between the first and second longitudinal channels and one of the first, second, and third niches.
