A spinal curvature correction device has a flexible tube having one or multiple lumens extending longitudinally through substantially the entire length of the flexible member. The lumens are a plurality of channels formed to receive multiple longitudinal members, or rods. Each rod is shaped to a desired curvature of a healthy spine or a curvature that will affect a correction of a diseased spine. The hollow, flexible tube is surgically placed along the axis of the spine and fixed. After fixation to the spinal elements is structurally stable, a plurality of curved semi-rigid rods is placed within the channels of the flexible tube. As additional rods are placed within the hollow flexible member, increased force is applied to the spine by the device, thereby moving the spine towards the desired curvature.

A catheter with basket-shaped electrode assembly with spines configured for hyper-flexing in a predetermined, predictable manner when a compressive force acts on the assembly from either its distal end or its proximal end. At least one spine has at least one region of greater (or hyper) flexibility that allows the electrode assembly to deform, for example, compress, for absorbing and dampening excessive force that may otherwise cause damage or injury to tissue wall in contact with the assembly, without compromising the structure and stiffness of the remaining regions of the spine, including its distal and proximal regions. The one or more regions of greater flexibility in the spine allow the spine to flex into a generally V-shape configuration or a generally U-shape configuration.

This document describes techniques and apparatuses enabling determination of health state trends for a consistent patient situation. Various noninvasive health monitors can be used to sense a patient's situation and health states, including disease progression, at those states. These noninvasive health monitors may also act passively and in a patient's normal course of life, which enhances many patient's desire to submit to monitoring, as well as increase consistency of use, as in many cases the patient does little or nothing to cause his or her health monitoring and health-trend determination.
