Imaging probe housing with fluid flushing
An imaging probe for use in a catheter for ultrasonic imaging is provided. The imaging probe includes a transducer backing and a transducer configured to generate and receive ultrasonic waves. The transducer includes a first surface and a second surface that is opposite the first surface. The first surface faces the transducer backing and the second surface is disposed at an angle sloping toward a catheter center axis in a proximal direction.
Imaging device with ultrasound transducer array
An imaging device (100) is disclosed comprising an ultrasound transducer array (101, 120, 130) having a plurality of ultrasound transducer elements defining an ultrasound emitting surface of the ultrasound transducer array; and an acoustic window (220) on the ultrasound emitting surface, said acoustic window comprising: a first layer (221) of a hydrocarbon elastomer contacting the ultrasound emitting surface, said first layer further containing an antioxidant; and a second layer (223) of a further hydrocarbon elastomer on the first layer, said second layer having a greater Shore A hardness than the first layer. Also disclosed are an ultrasound imaging system (10) comprising such an imaging device, such as catheter (100), and a method (300) of forming an acoustic window (220) on an ultrasound transducer array (101, 120, 130) for such a device (100).
REPLACEABLE ATTACHMENT FOR AN ULTRASOUND PROBE
A replaceable attachment for an ultrasound probe includes a ring-like fastening region for fastening the attachment to the ultrasound probe, and a flexible membrane arranged on the fastening region. A first liquid or gel-like contact medium is applied to an inner contact surface of the membrane. The contact surface makes contact with an end face of the ultrasound probe when an attachment is fastened to the ultrasound probe. Before the attachment is fastened, the first contact medium is distributed on the contact surface in such a manner that, in an array region of the contact surface, a quantity of the first contact medium per surface is at least twice as large as in a remaining region of the contact surface. A positioning and extent of the array region is adapted to a positioning and extent of a piezo array of the ultrasound probe.
Noise suppression in an optoacoustic system
An optoacoustic imaging system includes an ultrasound transducer array, first and second light sources and a switching power supply that generates power for the light sources. The switching power supply includes an input for impeding its switching operation. A data acquisition unit samples the ultrasound transducer array for a first predetermined period of time after a pulse of light from the first light source and for a second predetermined period of time after a pulse of light from the second light source and stores the sampled data. A master processor utilizes the input to impede operation of the switching operation of the switching power supply during the first predetermined period of time after a pulse of light from the first light source, and during the second predetermined period of time after a pulse of light from the second light source.
Medical headgear and transcranial ultrasound transmission device comprising the same
A medical headgear includes an ultrasound transducer and a headgear. The ultrasound transducer is configured to generate a low intensity ultrasound. The headgear supports the ultrasound transducer. The headgear includes a rear portion case including a slide guide configured to support an occipital and a support pad configured to support a crown. The headgear further includes a front portion case connected to the rear portion case to be slidably movable in one direction. The front portion case includes two temporal support pads configured to support both temporal portions.
ULTRASOUND SCANNER EYE PIECE CONSTRUCTION METHOD
The present disclosure is directed to improvement of a precision ultrasound scanner for imaging the human eye and in particular to method for the manufacture and assembly of an eye piece suitable for use with an ultrasonic arc scanning device. The method disclosed herein describes an improved eye piece for ultrasound imaging that reduces saline leakage around its optically and acoustically transparent membrane and improves the efficiency of assembly.
DISPOSABLE KIT
Arrangements described herein relate to systems, apparatuses, and methods for a disposable kit containing medical items configured for a medical device including a head cradle to support a head of a subject, the disposable kit includes a container that encloses a head cradle pad configured to be affixed to the head cradle, at least one fiducial marker configured to be disposed on a location at the head of the subject, and at least one enclosure configured to cover a portion of the medical device.
Ultrasonic imaging and energy delivery device and method
An ultrasonic device includes a driving circuit to provide drive power, a first transducer array to generate ultrasonic waves, the first transducer array being connected to receive power from the driving circuit, and a second transducer array to detect reflected or elicited ultrasonic waves incident on the device from a target and generate a signal based on those waves, the second transducer array being acoustically transmissive and disposed over the first transducer array such that the generated ultrasonic waves pass through the second transducer array. The second array is tuned to operate on top of the first. The functions of the two arrays may be reversed and the array tuned to operate with the first array receiving and the second array transmitting.
Probe Head-Cover Applicator and Method Thereof
A probe head-cover applicator and method for applying a probe head-cover to a probe head of an ultrasound probe. A probe head-cover applicator can include a tray including a cavity, an insert of a compressible material suspended over the cavity, and a probe head-cover adhered to the insert. The insert can include a first adhesive on an outward-facing surface of the insert facing away from the cavity. The probe head-cover can be adhered to the insert by the first adhesive. The probe head-cover can include a second adhesive on an outward-facing surface of the probe head-cover facing away from the insert. The second adhesive can be configured to adhere the probe head-cover to a probe head of an ultrasound probe when the probe head is inserted into the cavity.
REAL-TIME SAMPLING DEVICE
An elongated access device used in a medical system. The elongated access device slidably receives a medical tool and an ultrasound probe. The elongated access device includes a sheath and an intraluminal tip attached to the distal end of the sheath. The intraluminal tip includes ramp and nose donuts being spaced apart from one another and configured to be attached to one or more elongated sleeves. One or more orientation pins are engaged with the respective ramp and nose donuts and may be anchored within the sheath. The medical tool is engaged with a ramp formed in the ramp donut or a ramp received within the ramp donut. The ultrasound probe is configured to engage with the intraluminal tip so as to ensure that the medical tool directionality is oriented toward a target during a procedure.
