How HIFU Works ?
Why Sonablate HIFU?
All HIFU devices are not Equal.
HIFU is being used around the world to treat all types of soft tissue diseases, although some of the most extensive research has been for the treatment of localized prostate cancer. There is more than one device that uses HIFU to treat prostate cancer, so it is important to understand the characteristics and features of Sonablate HIFU that make it unique and its treatments customizable. Sonablate HIFU is a minimally invasive, precise medical procedure that uses ultrasound to rapidly heat and destroy tissue.
The Sonablate system incorporates customized treatment and safety technologies in an effort to strike a balance that has been difficult to achieve in prostate cancer treatment—increasing disease control capabilities while decreasing quality-of-life side effect risks.
Sonablate HIFU's Uniqueness
A Sonablate HIFU physician can completely customize a patient's treatment plan based on real-time tissue response, tissue density and location of vital structures. Competitive devices are limited to three pre-set power levels: primary, repeat HIFU and salvage (post radiation treatment), no patient receives a customized treatment based on their personal anatomy.
Sonablate HIFU technology allows for a smaller lesion size and the ability to treat prostates up to 40 grams without a TURP (transurethral resection of the prostate). The Sonablate creates a 10-12mm lesion, which conforms optimally around vital structures, allowing for complete tissue ablation throughout the gland and decreased risk for untreated tissue remaining. The competing device creates a 19-26mm lesion, which compromises the treatment around smaller critical spaces that can result in tissue being left untreated.
The Sonablate includes proprietary software and hardware advancements designed to increase the information feedback to the physician performing Sonablate HIFU and control the temperature of the probe, including:
Neurovascular bundle detection, which helps identify and display the position of the nerve bundles that help deliver blood flow to the penis. This software aids the physician in allowing them to avoid treating the neurovascular bundles, decreasing the risk of possible quality of life altering side effects.
Rectal wall monitoring to determine temperature of and proximity to the rectal wall. This aides the physician in the protection of the rectal wall tissue during therapy. Active cooling system that circulates chilled water through the probe during treatment and monitors temperature, which helps the physician in protecting the rectal wall tissue from heat generated during treatment.
Real-time image monitoring, which allows the physician to view and compare the original image to the real-time image being treated, for visual treatment confirmation as proven by Tissue Change Monitoring (TCM). The comparison of images will tell the physician the slightest degree of gland movement.
The competitor's system does not include the same features. Its features include external motion detection, which may not translate to gland movement, and use of refrigerated gel to keep temperatures low.
