Procedural issues include: type and degree of sedation, intubation versus no intubation, types of ventilation (spontaneous breathing or jet ventilation), rigid versus flexible tubes, the size of the cryoprobe
used, the number of samples taken, and how many segments or lobes should be sampled.
This is due in part to the cumbersome nature of the previously described procedures, which require multiple debridements of previously treated tissues and additional applications of the cryoprobe
to persistent scar tissue.
tip temperature and load) that are otherwise available with the cryoprobe
They are less bulky than the earlier liquid nitrogen cryoprobes
but still cannot operate indefinitely and require ventilation.
uses RF coils cooled to 30 K and integrated cooled RF preamplifiers to lower thermal noise, allowing a two or three magnitude amplification increase.
Moreover, as the enlarging ice ball approaches a ureter or another key structure, its progress can be halted by turning off a particular cryoprobe
Cryoassisted lumpectomy, which involves ultrasound-guided prelumpectomy insertion of a cryoprobe
through the center of the tumor via a 3-mm incision, appears to facilitate more accurate tissue resection and to decrease positive margin rates, said Dr.
NMR spectrometers with higher fields (>500 MHz) and spectrometers using the increased sensitivity of CryoProbe
technology could probably detect these two inborn errors of metabolism.
Bleeding from the cryoprobe
hole required bipolar coagulation, and an adhesion that formed between the coagulated area and the small bowel created a bowel obstruction.
It uses the Lustran 248 grade for the pistol-grip handle of the device's reusable cryoprobe
and the Lustran 348 material for the disposable control unit, which slips over the cryoprobe
These incisions allow for correct placement of the cryoprobe
