20080269846 | DEVICE FOR TREATMENT OF BLOOD VESSELS USING LIGHT - Light generating devices for illuminating portions of vascular tissue to administer photodynamic therapy, and usable with, or including a distal protection device. A first device includes a hollow tip, a flushing lumen, a guidewire lumen, and at least one of a light source, and a hollow light transmissive shaft that is adapted to accommodate a light source. If desired, the device can include a balloon, so that a portion of a body lumen between the balloon and the distal protection device is isolated when the balloon is inflated. A second device includes inner and outer catheters, the outer catheter including a balloon, and the inner catheter including a light source encompassed by another balloon. Yet another device is a catheter having two balloons and a sleeve extending there between. Within the sleeve, the catheter includes a light source and an expanding member. | 10-30-2008 |
20100145415 | LIGHT DELIVERY SYSTEM - A light delivery system to provide light treatment to a patient includes a catheter assembly having a plurality of light sources that transmit light towards a target site within a patient. In one embodiment, the light delivery system has a plurality of light sources mounted to a flexible transparent base that extends at least partially through a distal tip of the catheter assembly. The light sources can be wire bonded or mounted in a flip chip arrangement onto the base. In one embodiment to produce the distal tip, an array of light energy sources can be held by an array of holders of a fixture device. A vacuum is applied to secure each light energy source in a corresponding holder. While the vacuum is applied, the energy sources are electrically connected by wire bonding. The vacuum can be reduced or stopped thereby permitting removal of the light energy sources from the fixture device. | 06-10-2010 |

20110077464 | MEDICAL APPARATUS EMPLOYING FLEXIBLE LIGHT STRUCTURES AND METHODS FOR MANUFACTURING SAME - A method of manufacture and medical apparatus that provides an apparatus useful in illuminating at least a portion of a lumen of a body. The apparatus includes an elongated flexible member and a polymer encasement portion encasing a plurality of light emitters. The light emitters may be electrically coupled to one another without the use of wire bonds, and in some embodiments may be coupled without intervening electrical paths or traces. A maximum cross-sectional dimension of the polymer encasement portion may be less than twice a dimension of one of the light emitters. In some embodiments the maximum cross-sectional dimension is less than or equal to the sum of the dimension of one of the light emitters and a marginal dimension by which an outer portion of the polymer encasement portion extends beyond the light emitter. Light emitters may be arranged linearly, helically or in partially overlapping back-to-back relation. | 03-31-2011 |

20120209359 | LOW-PROFILE INTRALUMINAL LIGHT DELIVERY SYSTEM AND METHODS OF USING THE SAME - A light delivery system to provide light treatment to a patient includes an elongated catheter having a light emitter that transmits light towards a target site within a patient. The catheter is sized and configured to pass through anatomical body structures to reduce or eliminate trauma associated with the delivery procedure. A visualization system of the catheter can assist a user before, during, and/or after performing light therapy. The visualization system includes sensors that provide real-time imaging or feedback. | 08-16-2012 |
20130289411 | APPARATUS TO REMOVABLY SECURE AN ULTRASOUND PROBE TO TISSUE - A patch apparatus removably receives an ultrasound probe and attaches to a portion of a body, for example, via an adhesive. The patch apparatus may be disposable. The patch apparatus includes at least one cavity that sealingly holds a gel during use. The cavity may be sized to removably receive the ultrasound probe, in compression with the bodily tissue. Alternatively, the patch apparatus may include an adhesive or other fastener (e.g., hook and loop fastener) to removably retain the ultrasound probe. One or more magnets may indicate an orientation of the ultrasound probe or other information regarding an imaging procedure. An ultrasound probe may include a housing that is at least partially transparent, a display housed in the housing and visible from an exterior thereof, and one or more magnets to encode information regarding an orientation and/or procedure. | 10-31-2013 |
20130303915 | ULTRASOUND APPARATUS AND METHODS TO MONITOR BODILY VESSELS - An automated 3D ultrasound abdominal vessel monitor is capable of providing automated anatomical and physiological data on the large abdominal vessels, for example the Inferior Vena Cava (IVC). The 3D ultrasound abdominal vessel monitor includes one or more ultrasound transducers built into a housing or frame that in use sits on the upper abdomen, just below the ribcage. A disposable component can serve to secure the 3D ultrasound abdominal vessel monitor to the patient and provide a coupling medium between the 3D ultrasound abdominal vessel monitor and the skin of the patient. | 11-14-2013 |
20150072306 | ORAL ULTRASOUND WAVEGUIDE DEVICE - An oral ultrasound waveguide device is disclosed for use as an oral cleaning device. One embodiment includes a power source and an ultrasonic oscillator configured to be positioned outside an oral cavity, and a waveguide configured to couple ultrasonic energy from the ultrasonic oscillator to a mouth portion configured to be received in an oral cavity. The mouth portion can be configured to couple the ultrasonic energy outward from the mouth portion via at least one matching layer. | 03-12-2015 |
