Publication number: 20090287200Abstract: A method and an apparatus according to an embodiment of the invention includes a reflector and an optical fiber end portion disposed within a capillary for use in side-firing optical fibers. The reflector surface can be coated with a multilayer dielectric coating to increase the amount of side-fired laser energy. An outer member or cap can be used to protect the capillary when being inserted through a catheter or endoscope. The endoscope is then at least partially inserted into a patient's body to provide laser-based medical treatment. Multiple grooves can be defined on an outer surface of the optical fiber buffer layer to increase the surface area and improve the mechanical strength of the coupling between the optical fiber and the capillary. In some embodiments, the outer member or cap can also be coupled to the grooved surface portion of the optical fiber buffer layer.Type: ApplicationFiled: May 19, 2009Publication date: November 19, 2009Inventors: Brian Hanley, Jessica Hixon, Christopher L. Oskin, Edward Sinofsky

Publication number: 20090287197Abstract: A method and an apparatus according to an embodiment includes a distal end portion of an optical fiber disposed inside a lumen defined along a curved path within a capillary. The distal end surface of the optical fiber can be substantially flush with a portion of an outside surface of the capillary that defines a transmissive portion. The distal end portion of the optical fiber and the curved path can be collectively configured to direct laser energy through the transmissive portion in a lateral or side-fired direction that is offset from a longitudinal axis or centerline of the capillary. In some embodiments, more than one optical fiber can be disposed along the curved path. In other embodiments, more than one curved path can be defined within the capillary such that a distal end portion of an optical fiber can be disposed along each of the curved paths.Type: ApplicationFiled: February 12, 2009Publication date: November 19, 2009Inventors: Brian M.

Patent number: 7576861Abstract: An optical system for acquiring fast spectra from spatially channel arrays includes a light source for producing a light beam that passes through the microfluidic chip or the channel to be monitored, one or more lenses or optical fibers for capturing the light from the light source after interaction with the particles or chemicals in the microfluidic channels, and one or more detectors. The detectors, which may include light amplifying elements, detect each light signal and transducer the light signal into an electronic signal. The electronic signals, each representing the intensity of an optical signal, pass from each detector to an electronic data acquisition system for analysis. The light amplifying element or elements may comprise an array of phototubes, a multianode phototube, or a multichannel plate based image intensifier coupled to an array of photodiode detectors.Type: GrantFiled: March 27, 2008Date of Patent: August 18, 2009Assignee: Cytonome/ST, LLCInventors: John R.

Publication number: 20050065504Abstract: Guided ablation instruments are disclosed for creating lesions in tissue, especially cardiac tissue for treatment of arrhythmias, including atrial fibrillation. In one aspect of the invention, a percutaneous catheter is disclosed with an endoscope positionable in the instrument's distal end region to obtain an image. The image allows the clinician to determine whether contact has been achieved (or blood has been cleared from an ablative energy transmission path) before ablation begins or while ablation is occurring. In one embodiment, percutaneous ablation catheters are disclosed having at least one central lumen and one or more balloon structures at the distal end region of the instrument. Also disposed in the distal end region are an illuminating light source and an endoscope capable of collecting sufficient light to relay an image to the user. The instruments can further include an ablation element.Type: ApplicationFiled: June 10, 2004Publication date: March 24, 2005Inventors: Gerald Melsky, Jeffrey Arnold, Edward Sinofsky, Norman Farr

Patent number: 5254112Abstract: Apparatus for use in removing atherosclerotic plaque deposits in a blood vessel comprises a high power laser, an elongated, flexible catheter adapted to be inserted into and advanced through the blood vessel, a plurality of circumferentially arrayed optical fibers extending axially through the catheter, and an ultrasonic transducer at the distal end of the catheter for transmitting acoustical energy toward a selected area of the inner surface of a blood vessel in response to laser energy coupled through any one of the optical fibers and impinging upon the transducer. A detector proximal of the ultrasonic transducer is responsive to ultrasonic energy reflected from the blood vessel and produces a signal indicative of the tissue interfaces of the blood vessel. Laser energy can be transmitted from the high power laser through the same optical fiber used for the diagnostic procedure to ablate plaque in the blood vessel.Type: GrantFiled: October 29, 1990Date of Patent: October 19, 1993Assignee: C.
