Patent number: 9782221Abstract: Deep Tissue Low Intensity Laser Therapy or Treatment (DT-LILT) as described here is a novel methodology through which selective destruction of nociceptive (pain) nerves can be brought upon by a medical laser delivery system using the phenomenon of absorption and cell resonance. Using this method nerve cells that transmit pain can be selectively destroyed leaving the surrounding tissues intact as no heat is generated. The delivery system incorporates a fine needle through which a 703 nm (range 690 to 710) pulsed wave low intensity laser is delivered deep into the body, directly to the area of pain causing selective destruction of pain nerves. Laser devices based on this methodology should be used only by the physician or equivalent professional community since diagnosing and defining the area of pain is critical to providing successful pain relief.Type: GrantFiled: September 30, 2015Date of Patent: October 10, 2017Assignee: C Laser, Inc.Inventor: Pattanam Srinivasan

Patent number: 8888687Abstract: In one embodiment, an apparatus may include an endoscopic housing defining an opening disposed along a plane substantially normal to a longitudinal axis of the endoscopic housing. A rotatable member may be coupled to the endoscopic housing and may have a proximal portion configured to move from a stowed configuration to a deployed configuration when the proximal portion of the rotatable member is rotated about an axis substantially normal to the longitudinal axis of the endoscopic housing. The proximal portion of the rotatable member may be disposed on a distal side of the plane when in the stowed configuration and disposed on a proximal side of the plane associated with the opening when in the deployed configuration.Type: GrantFiled: October 27, 2010Date of Patent: November 18, 2014Assignee: Boston Scientific Scimed, Inc.Inventors: Isaac Ostrovsky, Ty Fairneny, Victor Shukhat, Jozef Slanda

Patent number: 8882659Abstract: An endoscopic device includes a proximal side contact portion coming into air-tight contact with an outer peripheral portion of the insertion section, and a cavity is defined between the insertion section and a fixed member to a distal direction side of the proximal side contact portion. In a protruding state of a hood, a first path which makes an inside of the hood communicate with the cavity is defined, and the hood is in air-tight contact with the fixed member over an entire circumference in circumferential directions at a distal side contact portion. In a housed state of the hood, a second path which makes the cavity to communicate with an outside of the fixed member is defined.Type: GrantFiled: March 7, 2013Date of Patent: November 11, 2014Assignee: Olympus Medical Systems Corp.Inventor: Kimihiko Naito

Patent number: 8876702Abstract: An electronic endoscope includes a distal end portion of an insertion portion which incorporates electronic components, a metal frame which holds an observation window, an earth member which is connected to a patient-side ground of an external device, and a static-protective member which is disposed in the distal end portion to have a predetermined clearance from the metal frame and is electrically connected to the earth member to let static electricity applied to the distal end portion flow to the earth member. With the configuration, the electronic endoscope prevents occurrence of trouble, a fault, and the like in an electronic component incorporated in the distal end portion due to applied static electricity.Type: GrantFiled: June 4, 2013Date of Patent: November 4, 2014Assignee: Olympus Medical Systems Corp.Inventors: Tomohisa Takahashi, Hironobu Ichimura

Patent number: 8876698Abstract: An endoscopic treatment system 1 of the present invention includes an overtube 2 that is inserted into the body of a patient. An endoscope 7 and a suturing device 8 are inserted into the overtube 2. The overtube 2 has a long and flexible tube main body 3, and a chamber 4 is provided at the distal end of the tube main body 3. The chamber 4 has a lateral hole 10 formed on the lateral surface thereof. The width of the lateral hole 10 is set such that a lesion can be drawn into the lateral hole 10 while preventing other organs on the periphery of the lesion from being drawn into the lateral hole 10.Type: GrantFiled: July 21, 2006Date of Patent: November 4, 2014Assignee: Olympus CorporationInventors: Yuji Sakamoto, Tsutomu Okada, Satoshi Miyamoto
