There is provided a catheter for assessing cardiac function, the catheter comprising an elongate shaft extending from a proximal end to a distal end, where the shaft comprises a lumen for a guidewire and/or a saline flush. The catheter further comprises at least one electrode disposed on the shaft for sensing electrical signals in a bipolar or unipolar fashion and applying pacing to a patient's heart, at least one sensor disposed on the shaft for detecting an event relating to the rapid increase in the rate of pressure increase within the left ventricle of a patient; and communication means configured to transmit data received from the electrode(s) and the sensor(s).

The present invention relates to an auxiliary artificial valve for implantation in blood vessel of a mammal patient. The artificial valve is provided with at least a first moving part and a second moving part configured to move between an closed position and an opened position, and a casing comprising at least one hinge, wherein the at least first moving part and second moving part are configured to be movably attached to the casing by means of said at least one hinge. e

The application provides a catheter positioning device for a catheter with a detection electrode. The device includes three pairs of excitation electrodes. The excitation electrode pairs are respectively lie on an X-axis, a Y-axis, and a Z-axis of a coordinate system. The device also includes a signal generator for providing excitation signals to the respective pairs of excitation electrodes. The device further includes a computing processing unit for measuring differential voltage indicative of impedance between the detection electrode and a first pair of excitation electrodes for determining an X coordinate of a position of the catheter, for measuring differential voltage indicative of impedance between the detection electrode and a second pair of excitation electrodes for determining a Y coordinate of the position, and for measuring differential voltage indicative of impedance between the detection electrode and a third pair of excitation electrodes for determining a Z coordinate of the position.

Provided herein is a system comprising (1) a microelectrode array (MEA) component comprising an integrated multiplexed (MUX) logic circuit; and (2) a microprocessor, e.g., MOSFET, such as a CMOS, wherein the MEA is in electrical communication with the microprocessor such that signals produced by the microelectrodes are transmitted to the processor through the MUX. The use of a MUX reduces the number of outputs used to communicate signals from multiple microelectrodes to the microprocessor. The two components are removably engageable with each other such that after one or more uses, the engaged MEA can be removed and replaced with a new MEA, without the necessity of disposing the microprocessor.

There is provided an apparatus (100) for monitoring swallowing in a subject. The apparatus (100) comprises a processor (102) configured to acquire, from a motion sensor (104), motion signals obtained from a feeding tube, when placed in the esophagus of the subject. The motion signals are indicative of swallowing motions transmitted along the feeding tube. The processor (102) is also configured to process the acquired motion signals to classify the acquired motion signals as indicative of the subject swallowing healthily or unhealthily.

Implantable and wearable devices and system for transmitting signals ultrasonically through biological tissue are implemented based on an Internet of Medical Things (IoMT) platform software and hardware architecture. The devices are size-, energy-, and resource-constrained and implement ultrasonic communication protocols and communicate with each other through ultrasound.

The present invention relates to a continuous blood glucose measurement device which is produced with an assembled body attachment unit inside an applicator so as to minimize a user's additional work of attaching the body attachment unit to the body, thereby enabling the body attachment unit to be attached to the body by simply activating the applicator, and, particularly, the present invention provides a continuous blood glucose measurement device which: is provided with a wireless communication chip in a body attachment unit so as to enable communication with an external terminal, thereby enabling simple and convenient use, without additional work of connecting a separate transmitter, and easier maintenance; and is activated by the user after the body attachment unit is attached to the body so as to enable the operation start time to be adjusted to an appropriate time according to user's needs, and to enable the operation to start in a stabilized state so that blood glucose can be measured more accurately.

The present invention relates to a body attachment unit for continuous blood glucose monitoring, in which a body attachment unit is manufactured so as to be assembled in an applicator, thereby minimizing additional work and allowing attachment of the body attachment unit to a body simply by operation of the applicator. In particular, a wireless communication chip is provided in the body attachment unit to enable communication with an external terminal, thereby enabling simple and convenient use without additional work of connecting a separate transmitter, and allowing easier maintenance.
