Guided Laser Surgery Offers Epilepsy Cure (980nm Laser)

Approach offers a significantly less invasive alternative to craniotomy, which is currently the most commonly used surgical treatment for epilepsy. For high-risk patients with deep brain lesions, the new technique can be particularly life changing, since a MRI-guided laser probe utilizes a much smaller pathway through the brain to reach the lesion; this reduced the risk of patient complications related to contact with surrounding brain tissue. In addition, the MRI-guided laser probe is inserted through a hole in the skull that is only 3.2mm in diameter, compared to the removal of a larger area of the skull bone for a craniotomy; and since it is a less invasive procedure, recovery time is shorter.

The optical system is based on a continuous wave 980-nm diode laser delivered through a fiber-optic with a one cm diffusing tip. The fiber is housed within a coaxial cooling catheter circulating room-temperature saline to cool the applicator, with the whole procedure taking place within a conventional 1.5 Tesla MRI scanner to provide real-time thermal imaging. The MRI confirms probe placement in the target, and also allows the surgeon to see the ablation of the lesion by the laser heat as it actually happens, with an automatic feedback system that shuts the laser off when the heat approaches nearby critical brain structures.

“ The main use of the MRI guidance is to actually be able to observe the target lesion before the ablation is made, and the position of the laser catheter tip can be exactly imaged by heating up it up by just a couple of degree,” said Angus Wilfong, MD, directly of Texas Children’s comprehensive epilepsy program.” This confirms the position of the catheter tip before continuing on with the ablation. We can also place safety markers on the MRI image to protect sensitive structures from reaching a predefined temperature to avoid damage.”

Five surgeries using the MRI-guided laser probe procedure have been successfully performed at the Texas Children’s Hospital on pediatric epilepsy patients ranging in age from 5 to 15 years old, with widely varied typed of brain lesions. In all cases, patients have been seizure free since surgery and most were released within one to five days.

Hook Shot Fiber--For BPH Treatment

prostatic hyperplasia (BPH) treatment of the prostate. It has been specially and successfully developed for a safe and effective contact ablation of prostate with high-power laser.

Specifications

Advantages of the Hook Shot Fiber™:  Working in contact mode: the Hook Shot Fiber™ optimizes the energy delivery in the procedure.  Resistant: > 375.000 J (Traditional side fibers withstand only up to 275.000 J).  Rapidity of surgery: with Hook Shot Fiber™ surgery is faster than with traditional side fibers.  Short learning curve: it's the same surgical technique as TURP.  User friendly: the Hook Shot Fiber™ simulates the hand of the surgeon thanks to the precise manipulator and the ergonomic design, giving a perfect control to the urologist.  The typical shape of the fiber tip allows treating the upper end of prostate without any view obstruction in a radius of 360º.  The rounded lens integrated in the tip of the Hook Shot Fiber™ constantly corrects the energy delivery. The energy applied is easily controlled thanks to a very precise delivery.  No degradation of Hook Shot Fiber™ during the surgery thanks to the self-cleaning surface of the tip that avoids the tissue to stick on it and carbonize.

Experience in the use of fiber optic laser scalpel

The laser scalpel is used in clinical infrared laser, in addition to CO2 laser optical output is used outside. There are two general types of fiber, an ordinary optical fiber; the other is the head with stones of various shapes, and the output fiber directly processed into a conical, spherical or 90 ° angle of illumination of the special fiber, most of these fiber a one-time use. Special fiber to tapered fiber most commonly used. Theoretically, the optical head with a jewel more durable, but more trouble to use this fiber, most need to bring cooling device, when used properly will result in precious little head off. In addition, this fiber is expensive and difficult to spread. Special processing of fiber ends can only be used once on the failure, the price is very expensive. Ordinary optical fiber can be used repeatedly, so the cost is low, the two fiber characteristics in common use are also different. Strictly speaking, a special optical fiber output only at the general shape of the different stones with the first, or the output of the first ordinary fiber processed into various shapes in advance to facilitate the clinical use of special optical fiber as compared to ordinary optical fiber flexibility, such as cones can only be used for cutting, not can be used with other treatments, and general fiber output can be also used to cut through the dressing, gasification and solidification of such treatment. In practice, the retirement of the special fiber output head amputated, you can use when ordinary optical fiber, which can greatly reduce costs, reduce the burden on patients.
