Patent number: 8409109Abstract: A reusable temperature sensing probe assembly comprises a temperature sensor strip extending from one end of a handle. The temperature sensor strip carries at least one temperature sensor for measuring temperature within a body cavity of a person, such as the rectum. The handle/temperature sensor strip is reversibly positionable within a unitary balloon/sleeve assembly comprised of a balloon portion and a sleeve portion. The balloon portion is comprised of a first interior space configured to hold the temperature sensor stip and a second interior space separate from the first interior space that is configured for inflation. An inflation tube has one portion sealed within the second interior space of the balloon portion and a second portion which extends through the sleeve portion for connection to a fluid source.Type: GrantFiled: March 28, 2005Date of Patent: April 2, 2013Assignee: Urologix, Inc.Inventors: Scott R. Tiesma, David A. Montecalvo

Patent number: 8403827Abstract: An endoscopic insertion aid includes a tube member, a pipeline and a plurality of balloons. The tube member allows an insertion section of an endoscope to be inserted therethrough, and guides the longitudinal movement of the insertion section. The pipeline is provided in the tube member, and communicates with a supply/discharge unit to supply a fluid to or discharge the fluid from the distal end of the tube member. The balloons are disposed on the outer periphery of the distal end of the tube member longitudinally along the tube member, communicate with the pipeline, and inflate/deflate in accordance with the supply/discharge of the fluid via the pipeline. The balloon disposed on the distal side of the tube member is inflated to have an outside diameter larger than that of the balloon disposed closer to the proximal side than the balloon disposed on the distal side when the balloons are inflated.Type: GrantFiled: July 18, 2007Date of Patent: March 26, 2013Assignee: Olympus Medical Systems Corp.Inventors: Raifu Matsui, Nobuyuki Matsuura, Seisuke Takase, Hidenobu Kimura, Takatoshi Yoshida

Patent number: 8353817Abstract: A self propelled, endoscopic apparatus formed of a flexible, fluid-filled toroid and a motorized or powerable frame. The apparatus may be used to advance a variety of accessory devices into generally tubular spaces and environments for medical and non-medical applications. The apparatus when inserted into a tubular space or environment, such as the colon of a patient undergoing a colonoscopy, is advanced by the motion of the toroid. The toroid's surface circulates around itself in a continuous motion from inside its central cavity along its central axis to the outside where its surface travels in the opposite direction until it again rotates into its central cavity. As the device advances within the varying sizes, shapes and contours of body lumens, the toroid compresses and expands to accommodate and navigate the environment. The motion of the toroid can be powered or unpowered and the direction and speed may be controlled.Type: GrantFiled: April 13, 2010Date of Patent: January 15, 2013Assignee: FUJIFILM CorporationInventors: Troy J. Ziegler, Timothy P. Sheridan, William T. Ryder

Patent number: 8343036Abstract: A thin sheath of flexible, flaccid material is introduced through openings in the body of an animal or human patient to permit surgical tools or fluids to be inserted and removed, or debris removed, during surgeries anywhere in the body to protect the tissue of the body from the instruments used. The sheath is inserted by an obturator which holds the sheath thereon by suction through an aperture in the obturator at its distal end. Once the sheath is inserted, suction is removed to release the sheath. Then a balloon on the distal end of the sheath is expanded to hold the sheath in place in the body while the obturator is removed. The sheath then remains in place with the balloon holding the distal end in the open position to enable fluids to flow through the sheath. After a procedure, the balloon is deflated and the sheath removed.Type: GrantFiled: December 22, 2010Date of Patent: January 1, 2013Inventor: James V. Harmon, Sr.

Patent number: 8303484Abstract: A self-propelled robotic device moves through bodily and other passageways by inflating regions of an overlying bladder along the length of the robotic device in a sequence that imparts motion to the device. The regions of the overlying bladder are inflated by energizing a plurality of coils, which are surrounded by a ferrofluid, in a sequence. The ferrofluid responds to the magnetic field created by an energized coil by creating a bulge in the side wall of the overlying bladder.Type: GrantFiled: November 19, 2009Date of Patent: November 6, 2012Assignee: National Semiconductor CorporationInventors: Peter J.
