Abstract: A microneedle balloon catheter includes a balloon fluidically coupled to a first fluidic channel and microneedles fluidically coupled to a second fluidic channel. The microneedles are on an exterior surface of the balloon. The catheter also includes a guiding sheath. In a first position of the microneedle balloon catheter the balloon, the microneedles, and a portion of the first and second fluidic channels are housed within the guiding sheath. In a second position of the microneedle balloon catheter the balloon and the microneedles are arranged outside of the guiding sheath. The first and second fluidic channels are fluidically isolated from each other.

Abstract: The invention pertains to a medical device: an ECMO (extracorporeal membrane oxygenation) catheter which can be used during right heart and lung failure. It pertains to a dual lumen catheter with a single port of entry which when in place bypasses the right heart and lungs while completing the veno-arterial circuit.

Abstract: In order to overcome or at least mitigate difficulties in compensating for movement of the target, for example a tumour during radiotherapy, a dosimetry apparatus and method embodying the present invention employ a dosimeter having at least one radiation detector and at least one magnetic position sensor located a predetermined distance apart. Radiation level readings from the radiation detector and position readings from the position sensor are monitored and correlated, conveniently according to time, to obtain the position of the radiation detector when a particular radiation level was detected.

Abstract: A detector assembly for multi-modality PET/SPEC/CT scanners comprises a first layer for detecting low energy gamma radiation and X-rays and a second layer for detecting high energy gamma radiation. The first layer is generally transparent to high energy gamma radiation. The second layer may advantageously provide measurement of depth of interaction of the high energy radiation. The first layer is preferably in the form of a thin CsI(TI) scintillator, while the second layer includes a pair of LSO/GSO scintillators. The detector assembly includes a photodetector, preferably in the form avalanche photodiode to transform the light signals from the scintillators into electric signals. The detector assembly is advantageously incorporated in a multi-modality PET/SPECT/CT scanner allowing simultaneous transmission and emission imaging with the same detection geometry.
