A biopsy and therapy device comprising: a needling unit for holding and inserting a biopsy needle; an imaging module comprising an ultrasound probe and an actuator for moving the probe in a reciprocal action; a first arcuate slide; a second arcuate slide in sliding engagement with the first arcuate slide and a linkage to which the first arcuate slide is mounted; said linkage arranged to move the first and second arcuate slides within a vertical plane; said needling unit mounted to said arcuate slide wherein the first and second arcuate slides are mounted perpendicular to each other so as to rotate the needling unit about respective first and second principal axes.

Provided herein is a pre-Caesarean method for collecting amniotic fluid from a patient. A needle is inserted into the incision site for the future C-section, which may be under ultrasound guidance, through which the amniotic fluid is drawn under a low level suction and, optionally, gravity to a sterile collection container. The method encompasses filtering and/or irradiating the amniotic fluid to collect biomolecules of interest such as growth factors and/or stem cells. Also provided is the sterile amniotic fluid or filtrates thereof collected by the method described herein.

A controller (240/340) for simultaneously tracking multiple interventional medical devices includes a memory (242/342) that stores instructions and a processor (241/341) that executes the instructions. When executed by the processor (241/341), the instructions cause the controller to execute a process that includes receiving timing information from a first signal emitted from an ultrasound probe (252/352) and reflective of timing when the ultrasound probe (252/352) transmits ultrasound beams to generate ultrasound imagery. The process executed by the controller also includes forwarding the timing information to be available for use by a first acquisition electronic component (232/332). The first acquisition electronic component (232/332) also receives sensor information from a first passive ultrasound sensor (S1) on a first interventional medical device (212/312). The timing information is used to synchronize the sensor information from the first passive ultrasound sensor (S1) on the first interventional medical device (212/312) with sensor information from a second passive ultrasound sensor (S2) on a second interventional medical device (216/316).

An ultrasonic endoscope system has an ultrasonic endoscope including an ultrasound transducer provided in a distal end part body, and a balloon for an ultrasonic endoscope that covers an outside surface of the ultrasound transducer, the balloon for an ultrasonic endoscope has an opening portion that is provided at one end in a first direction corresponding to a longitudinal direction of an insertion part and that is attached to the distal end part body, and includes a swelling portion that stores an ultrasonic wave transmission medium inside to be swellable, and a fixing portion that is in close contact with and fixed to the distal end part body, the distal end part body includes standing wall portions on both sides of the ultrasound transducer in a direction perpendicular to the first direction, and at least the fixing portion is in close contact with and fixed to the standing wall portion by contractile force of the fixing portion.

An ultrasonic imaging configuration rendering an image based on a reflected beam aligned with a needle insertion axis provides enhanced images and guidance. A percutaneous insertion guidance device for ultrasonic (US) imaging includes an US transducer and a reflector for redirecting imaging signals between the transducer and an imaged region. An enclosure or bracket is adapted to support the reflector at a predetermined angle based on a surgical target in the imaged region such that a forward beam direction from the transducer reflects in a direction of the needle insertion as the needle passes through a discontinuity or slot in the reflector. The resulting return signal is based on an axial alignment of the US signals with the needle travel towards the surgical target.

A microfluidic pressure sensor may include a bioinert shell having a cavity disposed therein. The cavity may include a reservoir and hydrophobic channel fluidly connected to the reservoir. Changes in pressure outside of the microfluidic pressure sensor may cause at least a portion of the shell to inflect into the reservoir thereby the fluid to move into the channel. The microfluidic pressure sensor may be bodily injected and the fluid level in the cavity may be detected using an ultrasound. The fluid level may be translated into a pressure measurement. The microfluid pressure sensor and uses thereof are suitable for bodily pressure measurements, including intra-abdominal pressure.

An ultrasound endoscope includes: an insertion portion to be inserted into a subject; an ultrasound transducer that is provided at a distal end of the insertion portion and includes plural piezoelectric element groups configured to transmit and receive ultrasound; a connector portion that is provided on a proximal end side of the insertion portion and includes plural connectors to which an external device is connected; and a cable portion including plural first coaxial lines connected to the piezoelectric element groups configured to transmit the ultrasound to a first area, and plural second coaxial lines connected to the piezoelectric element groups configured to transmit the ultrasound to a second area, the first coaxial lines being shorter in length than the second coaxial lines, the first area and the second area being where the ultrasound is transmitted.

A medical device for injecting fat while simultaneously allowing the injection site to be viewed with ultrasound. The device may comprise a handle with a front portion and a rear portion, a cannula having a cannula tip, extending from the front portion of the handle, and an ultrasound probe attached to the handle, the ultrasound probe comprising an ultrasound head. The ultrasound head is aligned with and spaced apart from the cannula tip, and remains so aligned during the injection process so that the injection area may be continuously viewed during the procedure.

A medical instrument includes a printed ultrasound sensor, a surface, at least one non-conductive material, and at least one pair of contacts. The ultrasound sensor includes an array of ultrasound transducers printed on a non-conductive surface of the medical instrument. The medical instrument contains multiple conductive and nonconductive layers. The at least one pair of contacts are electrically coupled to the ultrasound sensor and operably coupled to the conductive layer, the conductive layer coupled to a measurement device, which converts electrical signals from the ultrasound sensor into images displayed on a display unit. The location of the medical instrument can be visualized in real time on the display unit.
