The present invention provides a method of obtaining a classification boundary, to limit an axial depth in a puncturing operation. The following steps of method comprises: At first, obtaining a plurality of tomographic images from the axial depth of a tissue is performed. Then, obtaining a plurality of characteristic values from the tomographic images, the characteristic values are classified by a Support Vector Machine method. A classification boundary will be obtained through a distribution of the graph for defining a specific compartment of the tissue. In addition, an automatic recognition method and system using the above mentioned method are also disclosed in the present invention.

Example systems and techniques for denervation, for example, renal denervation. In some examples, a processor determines one or more tissue characteristics of tissue proximate a target nerve and a blood vessel. The processor may generate, based on the one or more tissue characteristics, an estimated volume of influence of denervation therapy delivered by a therapy delivery device disposed within the blood vessel. The processor may generate a graphical user interface including a graphical representation of the tissue proximate the target nerve and the blood vessel and a graphical representation of the estimated volume of influence.

A sensing electrode selection algorithm is disclosed for use with an implantable pulse generator having an electrode array. The algorithm automatically selects optimal sensing electrodes in the array to be used with a pre-determined stimulation therapy appropriate for the patient. The algorithm preferably senses stimulation artifacts using different sensing electrodes, and more specifically different sensing electrode pairs as is appropriate when differential sensing is used. The algorithm further preferably senses these stimulation artifacts with the patient placed in two or more postures. The algorithm processes the stimulation artifact features measured at the different sensing electrodes and at the different postures to automatically determine one or more sensing electrode pairs that best distinguishes the two or more postures given the prescribed stimulation therapy.

Systems, devices, and techniques for analyzing evoked compound action potentials (ECAP)signals to evaluate and select an electrode combination.

A rectal tonometer device for quantitatively detecting and measuring a rectal tone of a patient. The device includes a main body including a cavity within and a deformable tip, including a pressure sensor, partially disposed in the cavity and extending from the main body. Deforming the tip may actuate the pressure sensor. The rectal tonometer device further includes a circuit board disposed within the cavity, communicatively coupled to the deformable tip capable of accepting a pressure signal from the pressure sensor and measuring, based on the pressure signal, the rectal tone of the patient.

The present disclosure provides a novel method for accessing the spinal disc space, instrumentation for discectomy and implantation of spinal implants, and unique designs for intervertebral spinal implants. In particular, the present disclosure describes modular interlocking spinal implants that can be assembled during surgery, for the purpose of implantation between vertebral bodies that is unique to the disc space, creating vertebral stabilization, correction of spinal scoliosis, reducing segmental motion, greater arthrodesis potential, reduction of pain, and other benefits. The present disclosure provides increased permutation of implant shapes to match a subject specific spinal disease.

Provided is a chest measuring device configured to be attached to and detachable from a body and capable of inducing a correct posture of a subject and at the same time, correcting an abnormal alignment of the spine by analyzing measured values of left and right chests and generating vibrating motion to a chest that needs stimulation, a scoliosis correction system enabling a subject to conveniently measure his/her spinal condition alone without the help of others by including sensors contacting left and right ribs and left and right transverse processes of lumbar vertebrae of the subject and also including a wearable internet of things (IoT) capable of detecting sensing values of muscles used to determine a spinal condition of the subject, a system for remotely diagnosing spine remotely diagnosing the spine of a patient by processing trunk movement data of the patient collected through a wearable measuring device, and a wearable measuring device enabling a subject to self-diagnose a spinal condition and correct a posture based on the result.

The present invention provides an energy emission device comprising: one or a plurality of energy emission means for emitting at least one type of energy selected from the group consisting of an electromagnetic wave or an electromagnetic stimulation, an elastic wave, an oscillatory wave and heat to at least one position of a subject selected from the group consisting of the brain, the spinal cord, the cerebrospinal fluid or the flow passage thereof and the brain cell interstitial fluid or the flow passage thereof; an energy controlling means for controlling an amount of energy emitted from the energy emission means; and a means for obtaining information relating to wakefulness and/or a sleeping state of the subject, in which the energy controlling means controls the amount of energy emitted depending on the information relating to the wakefulness and/or the sleeping state.

An echo planar imaging technique in which a quadruple echo gradient and spin echo echo-planar imaging pulse sequence is utilized. The pulse train includes generation of two echo trains between an excitation pulse (90) and a refocusing pulse (180) to achieve two gradient echo images (also called T2*-weighted images); with one echo train directly after the 180 pulse, leading to asymmetric spin echo images (T2-weighted images); and a last echo train afterward that generates spin echo images (T2-weighted). The technique has a number of advantages over existing techniques with regard to voxel size, mapping relative oxygen extraction, determining permeability, determining relative cerebral blood volume, vessel parameters (diameter, density, size, arterial/venous, etc.), stroke imaging, imaging perfusion, fMRI imaging, and additional benefits.
