    摘要: A catheter with a balloon anchor may be sized to fit through an inner needle and introduced into the patient through the needle. The inner needle may comprise an atraumatic needle with a side port and/or a blunt tip. The catheter may include a radiopaque coil disposed over the distal portion of the catheter body to assist with catheter placement when viewed with fluoroscopy and/or x-ray. The distal portion of the catheter can be very flexible. A balloon inflation tube may terminate proximal to a proximal end of the expandable balloon anchor such that the distal portion of catheter can be flexible. This termination of the inflation tube may also position the inflation tube away from the annulus and nerve roots, so as to avoid irritation of the annulus and rubbing of the nerve roots that may potentially obscure FAD test results.

    摘要: A method includes heating a first portion of a tubular member to a first temperature greater than a temperature of a second portion of the tubular member. The first portion of the tubular member is different from the second portion of the tubular member. The tubular member is stretched after the heating such that a length of the first portion of the tubular member is associated with a width of an anulus of an intervertebral disc. After the heating and the stretching, the tubular member is disposed within a mold cavity at least until the first portion of the tubular member has a second temperature less than the first temperature and such that an outer diameter of the tubular member in a collapsed configuration is substantially constant along a longitudinal length of the tubular member.
