A spinal implant system for restricting flexion of a spine includes an elongate band proportioned to engage at least two spinous processes. During use, the band is positioned engaging the spinous processes at a spinal segment of interest, where it restricts flexion at the segment. The length and tension of the band may be adjustable following to implantation using percutaneous or transcutaneous means.

Spinal implants for limiting flexion of the spine are implanted between a superior spinous process and an inferior spinous process or sacrum. The implants include upper straps which are placed over the upper spinous process, while the lower portions of the implant are attached to the adjacent vertebra or sacrum. The attachments may be fixed, for example using screws or other anchors, or may be non-fixed, for example by placing a loop strap through a hole in the spinous process or sacrum.

A curved sensor device, such as an ultrasonic transducer array, is fabricated from a flat micromachined sensor (such as cMUT or pMUT) array constructed using micromachined electromechanical systems (MEMS) techniques. The device comprises: a support structure comprising a spine having a profile that is generally curved and a multiplicity of teeth extending from one side of the curved spine; and a multiplicity of sensors built on the support structure. The spine can be bent forward or backward and attached to a curved front face of a support member, thereby causing the sensors to adopt a curved array.

A stack of sheets of sheet material is stapled along an axis and fed to a position from which it is folded along the axis by a blade to form a booklet having a curved spine. The blade also inserts the booklet into a position between clamping jaws and determines its final position therebetween. Rotatable guide rollers guide the sheets into the gap and are fitted with one-way clutches to resist upward movement of the folded sheets upon retraction of the blade from the gap. In a first mode of operation, the curved spine of the booklet protrudes a short distance beyond the jaws. The spine is then flattened by a forming roller which passes along the spine. In a second mode of operation, the spinal portion lies between the jaws and the curved end surface is flattened by the clamping force alone. The first mode is suited to booklets having or more sheets; the second to booklets having fewer than sheets or having loop staples and any number of sheets.
