摘要:
Systems and methods are provided for stimulating one or more nerves with an implantable device. The implantable device may comprise an antenna circuit including a loop antenna and a control circuit including a rectifying diode for rectifying an alternating voltage induced in the antenna circuit by an external electromagnetic field. The implantable device may also include a chargeable storage element for storing energy from the rectified voltage without using a battery. The device may also include an electrode array containing a set of electrodes for emitting an electric field using the stored energy in response to a control signal received from the control circuit. The components of the device may be affixed onto a soft polymer substrate including a linkable peripheral tab on at least two edges of a substantially rectangular body section of the substrate for forming a cuff about the one or more nerves to be stimulated.

The present invention relates to the use of a NIR fluorescent probe comprising an aza-bicycloalkane based cyclic peptide labelled with a Cy5.5 dye moiety in the fluorescence- guided surgery of pathologic regions and to an optical imaging method that comprises using this fluorescent probe for the identification and demarcation of tumor margins during the surgical resection.
摘要:
A nerve integrity monitoring device includes a control module and a physical layer module. The control module is configured to generate a payload request. The payload request (i) requests a data payload from a sensor in a wireless nerve integrity monitoring network, and (ii) indicates whether a stimulation probe device is to generate a stimulation pulse. The physical layer module is configured to (i) wirelessly transmit the payload request to the sensor and the stimulation probe device, or (ii) transmit the payload request to a console interface module. The physical layer module is also configured to, in response to the payload request, (i) receive the data payload from the sensor, and (ii) receive stimulation pulse information from the stimulation probe device. The data payload includes data corresponding to an evoked response of a patient. The evoked response is generated based on the stimulation pulse.
摘要:
A device for detecting impulses within a nerve, the device comprising a support for securing to the epineurium of the nerve, at least one spike extending from said support, arranged to penetrate the perineurium and at least one chemical sensor arranged on a surface of the at least one spike.
摘要:
The neural health or state of a subject is assessed. A recording is obtained of a compound action potential arising in neural tissue of the subject. The recording is processed to determine whether a profile of the recorded compound action potential is anomalous, such as by exhibiting doublets, peak broadening or deformation, or other anomaly. An indication is output regarding the neural state of the subject based on determined anomalies in the recorded compound action potential.
摘要:
A method for stimulating a facial muscle includes the steps of mapping a facial nerve being connected to the facial muscle, locating the facial muscle in response to the mapping of the facial nerve and stimulating the facial nerve by applying an electrode and stimulating the facial nerve with current. The step of mapping includes the step of applying current to the cheek by an electrode and moving the electrode in response to the reaction of applying current to the cheek.
