Highly flexible mapping and treatment device

A device and system for providing mapping and treatment capabilities without increasing stiffness of the device. An embodiment of a device may include a flexible elongate body and at least one mapping element on the distal portion of the elongate body. Each mapping element may be an area of thermally conductive material, such as metallic nanoparticles, that is embedded within, integrated with, or deposited on the elongate body. The flexibility of the areas of thermally conductive material is at least substantially the same as that of the elongate body so the device may include many electrodes without compromising flexibility and maneuverability of the device. Alternatively, the device may include a treatment element coupled to the elongate body, such as a balloon. The mapping elements may be embedded within, integrated with, or deposited on the balloon and may have at least substantially the same flexibility as that of the balloon.

SURGICAL TOOLS FOR SPINAL FACET THERAPY TO ALLEVIATE PAIN AND RELATED METHODS

Methods and surgical tools for treating back pain use a spinal facet debridement tool with cautery and denuding action and minimally invasive protocol that can denude and cauterize soft tissue associated with a synovial capsule of the spinal facet joint.

LASIK FLAP CUTTING PATTERNS INCLUDING INTRASTROMAL POCKET FOR BUBBLE MANAGEMENT

A method implemented in an ophthalmic surgical laser system that employs a resonant scanner, scan line rotator, and XY- and Z-scanners, for forming a corneal flap in a patient's eye with improved bubble management during each step of the flap creation process. A pocket cut is formed first below bed level, followed by the bed connected to the pocket cut, then by a side cut extending from the bed to the anterior corneal surface. The pocket cut includes a pocket region located below the bed level and a ramp region connecting the pocket region to the bed. The bed is formed by a hinge cut and a first ring cut at lower laser energies, followed by a bed cut and then a second ring cut, which ensures that any location in the flap bed is cut twice to minimize tissue adhesion. The side cut is formed by multiple side-cut layers at different depths which are joined together. All cuts are formed by scanning a laser scan line generated by the resonant scanner.

System and method for administering light therapy to curved and large surfaces

A system and method are disclosed that use a flexible guide (flap) and a scanning method to control the delivery of light dose to a treatment area. This approach overcomes the non-reliable delivery of light dose with a flap that conforms to the target area. Dosimetry control can be improved through the use of a computer controlled motor to move the laser fibers at known speed over the target tissue. In some embodiments, treatment time is reduced and illumination of large surfaces is achieved by using multiple fibers to deliver the light simultaneously.
