Claims17
A composite structure comprising a body which is circular in cross section and which has proximal and distal extremities, said body having a surface and cladding covering at least a part of said surface of the body and being in intimate contact with the surface, said body and said cladding being formed of different materials, said cladding extending from the proximal extremity toward the distal extremity with a portion of the distal extremity being free of cladding, the distal extremity having at least one tapered portion and a portion of uniform diameter extending distally of the tapered portion, the cladding extending over at least a portion of the tapered portion, the portion of uniform diameter being free of the cladding to provide greater flexibility for the distal extremity.
A composite structure comprising a body which is circular in cross section and which has proximal and distal extremities, said body having a surface and cladding covering at least a part of said surface of the body and being in intimate contact with the surface, said body and said cladding being formed of different materials, said cladding extending from the proximal extremity toward the distal extremity with a portion of the distal extremity being free of cladding, said cladding being comprised of multiple layers formed of different materials, one of the materials being a superelastic shape memory alloy and another of the materials being an actuator shape memory alloy.
A composite structure comprising a body which is circular in cross section and which has proximal and distal extremities, said body having a surface and cladding covering at least a part of said surface of the body and being in intimate contact with the surface, said body and said cladding being formed of different materials, said cladding extending from the proximal extremity toward the distal extremity with a portion of the distal extremity being free of cladding, said cladding being comprised of multiple layers formed of different materials, at least two of the materials being actuator shape memory alloys.
A composite structure comprising a body which is circular in cross section and which has proximal and distal extremities, said body having a surface and cladding covering at least a part of said surface of the body and being in intimate contact with the surface, said body and said cladding being formed of different materials, said cladding extending from the proximal extremity toward the distal extremity with a portion of the distal extremity being free of cladding, said body being comprised of first and second shape memory alloys, the first shape memory alloy having superelastic characteristics and the second shape memory alloy having actuation characteristics.
A composite structure comprising a body which is circular in cross section and which has proximal and distal extremities, said body having a surface and cladding covering at least a part of said surface of the body and being in intimate contact with the surface, said body and said cladding being formed of different materials, said cladding extending from the proximal extremity toward the distal extremity with a portion of the distal extremity being free of cladding, at least one of said materials being a nickel titanium alloy, said cladding being formed of a nickel titanium alloy.
A composite structure comprising a body which is circular in cross section and which has proximal and distal extremities, said body having a surface and cladding covering at least a part of said surface of the body and being in intimate contact with the surface, said body and said cladding being formed of different materials, said cladding extending from the proximal extremity toward the distal extremity with a portion of the distal extremity being free of cladding, said body being comprised of a plurality of cores of one material which are arranged to lie in a plane, said cladding covering said plurality of cores, said body being formed of a nickel titanium alloy and said cores being formed of a material having a different rigidity from that of the nickel titanium alloy.
A composite structure comprising a body which is circular in cross section and which has proximal and distal extremities, said body having a surface and cladding covering at least a part of said surface of the body and being in intimate contact with the surface, said body and said cladding being formed of different materials, said cladding extending from the proximal extremity toward the distal extremity with a portion of the distal extremity being free of cladding, said body being formed of a plurality of circumferentially spaced apart cores, said cores being covered by said cladding, said cores being formed of stainless steel.
A composite structure comprising a body which is circular in cross section and which has proximal and distal extremities, said body having a surface and cladding covering at least a part of said surface of the body and being in intimate contact with the surface, said body and said cladding being formed of different materials, said cladding extending from the proximal extremity toward the distal extremity with a portion of the distal extremity being free of cladding, said shape memory alloy having an electrical resistance, said cladding having an electrical resistance which is substantially less than the electrical resistance of the shape memory alloy, said cladding being comprised of a material selected from the group consisting of copper, silver and gold.
