  • Patent number: 10441136
    Abstract: A method of treatment comprises intravascularly securing an anchor extending from an anchor member at least partially within a vessel lumen such that blood flows unobstructed through or past the anchor. While the anchor is secured, a distance of the anchor member, between the anchor and a barrier or membrane projecting distally from a deployment catheter, is adjusted such that an open area defined by the barrier or membrane is placed against or adjacent to a portion of a patient tissue. Adjusting the distance of the anchor member comprises moving the deployment catheter distally with respect to the anchor member. The method also comprises displacing blood with a transparent fluid from the open area, and while the anchor is secured, articulating the barrier or membrane circumferentially around the anchor. The method also includes treating the tissue while visualizing through the transparent fluid.

  • Patent number: 8852083
    Abstract: Wireless capsule endoscope technology has been used to image portions of the gastrointestinal (GI) tract, particularly the small bowel. However in other GI organs, especially those having larger-lumens, the capsule may become destabilized and tumble, precluding meaningful interpretation of the acquired images. The present invention describes a method and apparatus for permitting capsule imaging of organs having larger-lumens without tumbling, and includes an outer shell surrounding the capsule that targets the colon, as an example. Once the colon has been reached, the shell breaks or dissolves, and allows expansion of expandable materials attached to each end of the capsule, thereby stabilizing the capsule in the targeted organ, while permitting it to be moved by peristalsis and/or other means for locating the capsule. Imagers and light emitting diodes (LEDs) are activated during the expansion process, and enable overlapping of images.

  • Patent number: 8790246
    Abstract: A self-propelled device for locomotion through a lumen, comprising a set of serially arranged inflatable chambers, and incorporating a number of novel aspects. To enable easy insertion and use, the rigidity of the device is increased by means of rigid inserts in the balloons, or by use of stiff springs between segments. The working channel can be attached to the distal chamber of the device, such that it is pulled from the leading end of the device during inflation, rather than being pulled from the trailing end of the device during deflation. Lumen wall inspection or treatment facilities are enabled by means of a camera or treatment arm mounted between two distally positioned balloons, the device is able to provide observation capabilities to the lumen wall, yet without becoming excessively dirty by exposure to the front end of the device, as in prior art camera units.

  • Patent number: 8771174
    Abstract: To provide a tool for safely and reliably securing a route for endermically approaching the interior of the body; more specifically, an endoscope-equipped puncture balloon that is designed to allow a balloon that does not immediately burst when punctured by a puncturing needle or the like to be used as a target, and that can be used by installing or inserting an endoscope in a tube holding such balloon. In a thin-walled main body tube 1 equipped with an endoscope-installed section at the rear end, a balloon 2 is disposed on the front surface thereof, and a branch tube 4 communicating with the interior of the balloon 2 in a gas-liquid flow manner is disposed on the main body tube 1, the branch tube 4 having a connector 5 annexed to the rear end thereof; thus it is not until the liquid in the balloon is absorbed without the balloon immediately bursting when punctured by a puncturing needle that a bore can be secured until the balloon is contracted.

  • Publication number: 20140180126
    Abstract: The invention provides an intravascular catheter with an expandable member such as a balloon with an imaging device on a surface of the expandable member. The imaging device can use an optical fiber on a surface of the expandable member to image a treatment site. Since an image can be captured directly from the surface of the expandable member, an operator can examine the treatment site while positioning the expandable member. With the treatment site in view, the operator can deliver the treatment (e.g., inflate the balloon or deploy the stent) with confidence that it will be located properly.
