Claim 18:
19. An intramedullary sleeve apparatus (100) configured to hold and cure a curable material comprising injectable bone cement, cured resin, or a combination thereof to form an intramedullary device that conforms to surrounding tissue and supports a bone of a patient during bone fracture treatment, the apparatus (100) comprising:
a. an inner non-resorbable intramedullary sleeve (110), having at least one proximal end and at least one distal end, wherein an interior of the inner sleeve (110) comprises a reinforcing material (112);
b. an outer intramedullary sleeve (120) disposed around the inner sleeve (110), having at least one proximal end and at least one distal end;
c. one or more access valves (130) disposed through the inner sleeve (110) and the outer sleeve (120) so as to allow access into the inner sleeve (110), wherein each access valve is disposed at at least one proximal end of the inner sleeve (110) and the outer sleeve (120), at least one distal end of the inner sleeve (110) and the outer sleeve (120), or a combination thereof, wherein an access valve (130) of the one or more access valves comprises a first port (132) to allow for injection of a curable material, and a second port (134) to allow insertion of a light guide (140);
d. the light guide (140) disposed through the second port (134) of the access valve (130), the light guide (140) comprising a flexible plug (142) configured to seal the light guide (140) in the second port (134) of the access valve (130); and
e. one or more sensors disposed on an outer surface of the outer sleeve (120), the inner sleeve (110), or a combination thereof;
wherein each sensor of the one or more sensors is capable of measuring pressure, stress, strain, temperature, or a combination thereof with respect to the sleeve component and the bone;
wherein the inner sleeve (110) and the outer sleeve (120) are fabricated by electrospinning;
wherein the inner sleeve (110), the outer sleeve (120), or a combination thereof are configured to stretch to match growth of the bone;
wherein the apparatus (100) is configured to be removed by external accessories;
wherein one or more properties of the inner sleeve (110) and the outer sleeve (120) are determined based on a bone mass index of the patient;
wherein the inner sleeve (110) is configured to conform to the intramedullary cavity;
wherein the outer sleeve (120) is configured to conform to the intramedullary cavity and stretch to match growth of the bone.
