Spinal fixation member

A system for fixing spinal vertebrae utilizes a spinal rod that has varying properties along its length such that a lower stiffness portion is placed in the cranial or caudal end positions of the spinal rod to address potential adjacent level failure. The spinal rod includes a core member formed of a first material having a first modulus of elasticity and a sheath member formed of a second material having a second modulus of elasticity different from the first modulus of elasticity.

System and dilating and adjusting flexibility in a guiding device

The helical members are configured so that the dilatable tip increases in stiffness when the helical members are tensioned by a resistance to rotation in the winding direction. In some embodiments, application of relative force between coaxial inner and outer tubular members is used to control the dilation, stiffness and drilling of the guiding member..


Suspension for acoustic device

An acoustic device includes a diaphragm, a frame, and a suspension element that couples the diaphragm to the frame such that the diaphragm is movable in a reciprocating manner relative to the frame. The suspension element includes a first surround element and a second surround element that have respective inner landings between which a region proximal to an outer edge of the diaphragm is disposed.
