A device and method for imaging vasculature are provided. The device includes an imaging probe to be inserted into a vasculature. The imaging probe emits infrared light through blood toward the vasculature, and gathers reflected from the vasculature for imaging. The device includes an infrared light source optically coupled to the imaging probe to provide infrared light, and an infrared light detector optically to the imaging probe to generate an imaging signal from the reflected light that is gathered. The device further includes a controller coupled to the infrared light source and coupled to the infrared light detector to generate an image of the vasculature from the imaging signal. The controller may employ ballistic photon imaging techniques, gated imaging techniques, polarizing light imaging techniques, structured light imaging techniques, and the like.

The apparatus for being inserted into a living body and acquiring biological information includes a balloon inserted into the living body to expand or contract, one or more electrodes disposed on a surface of the balloon, and one or more fine protrusions disposed on surfaces of the electrodes to come into contact with the living body.

A catheter is disclosed with a priming hole for exhaust at a distal portion of the catheter, the priming hole being used when filling with a priming solution is performed, and movably and rotatably accommodates an imaging core. The catheter includes a first connector that is provided at a rear end portion of the catheter and is supported by a fixed connector portion of a motor drive unit included in an imaging apparatus for diagnosis and a second connector that is supported by a movable connector portion of the motor drive unit. The catheter includes a reservoir, which is provided in the first connector and has a volume which decreases depending on a pull-out length of the second connector from the first connector, and a supply route, through which a priming solution injected from a priming injection port is supplied to the reservoir.

The present invention relates to non-invasive blood glucose measuring apparatus and method. More specifically, the apparatus is inserted into a blood vessel of a human body, and at a point of time when a measurement is desired, wirelessly transmits power so as to be operated, wherein a dipole antenna-form sensor measures a change in a specific parameter depending on a blood glucose level. The apparatus measures the blood glucose in a non-invasive manner, wherein a display unit that is present outside the human body receives the parameter value through wireless communication and displays a corresponding blood glucose level.

A bio imaging system includes a plurality of light emitters configured to irradiate light, and a plurality of sensors configured to detect light reflected by an internal tissue of a living body. Each sensor includes a plurality of photo-detecting elements having different absorption peak wavelengths in relation to each other.

An apparatus for obtaining information regarding a biological structure(s) can include, for example a light guiding arrangement which can include a fiber through which an electromagnetic radiation(s) can be propagated, where the electromagnetic radiation can be provided to or from the structure. An at least partially reflective arrangement can have multiple surfaces, where the reflecting arrangement can be situated with respect to the optical arrangement such that the surfaces thereof each can receive a(s) beam of the electromagnetic radiations instantaneously, and a receiving arrangement(s) which can be configured to receive the reflected radiation from the surfaces which include speckle patterns.

In part, the disclosure relates to intravascular data collection systems and the software-based visualization and display of intravascular data relating to detected side branches and side branch obstruction. An estimate of side branch diameter can be made based on a vessel profile or a maximum diameter of a vessel at a distal and proximal location relative to the side branch. A amount of side branch obstruction may be determined by comparing an observed side branch diameter with in the image data with the estimated side branch diameter. In addition, an amount of blood flow obstruction may also be determined.

A catheter device for placing a sensor device comprises a shaft and a coupling device, arranged at the shaft, for coupling the catheter device to the sensor device comprising at least one bracket element. The coupling device comprises a coupling element and a locking element adjustable with respect to the coupling element, wherein the coupling element comprises at least one engagement section with which the at least one bracket element of the sensor device can be brought in engagement, wherein the locking element is designed, in a coupled position, to block the at least one bracket element at the at least one engagement section, and is adjustable with respect to the coupling element so as to release the at least one bracket element for detachment from the at least one engagement section.

An implantable extravascular pressure sensing system includes a cuff including a first brace portion affixed to a second brace portion and defining a longitudinal axis therebetween. The first brace portion defines a fluid chamber, the fluid chamber defining a recessed aperture. A first lateral restraint and a second lateral restraint are disposed between the first brace and the second brace, the first lateral restraint and the second lateral restraint being configured to be displaceable in a direction orthogonal to the longitudinal axis. A diaphragm is coupled to the fluid chamber and sealing the recessed aperture. A fluid is disposed within the fluid chamber for exhibiting a hydraulic pressure in communication with the diaphragm. A pressure sensor is coupled to the first brace portion, the pressure sensor being configured to measure a change in the hydraulic pressure when a force is imparted on the diaphragm.
