20110196392 | APPARATUS AND METHODS FOR PERFORMING TRANSLUMINAL GASTROINTESTINAL PROCEDURES - Methods and apparatus are provided for diagnosing and treating digestive or other organs (as well as other parts of the body) endoluminally and transluminally, via instruments passed into the GI tract per-orally and/or per-anally. The instruments may, for example, pass transluminally out of the stomach and/or the colon through a breach formed therein in order to conduct diagnostic or therapeutic procedures, such as gastroenterostomy. | 08-11-2011 |
20110306833 | FLOW REDUCTION HOOD SYSTEMS - Flow reduction hood systems are described which facilitate the visualization of tissue regions through a clear fluid. Such a system may include an imaging hood having one or more layers covering the distal opening and defines one or more apertures which control the infusion and controlled retention of the clearing fluid into the hood. In this manner, the amount of clearing fluid may be limited and the clarity of the imaging of the underlying tissue through the fluid within the hood may be maintained for relatively longer periods of time by inhibiting, delaying, or preventing the infusion of surrounding blood into the viewing field. The aperture size may be controlled to decrease or increase through selective inflation of the membrane or other mechanisms. | 12-15-2011 |
20120004577 | TISSUE VISUALIZATION DEVICE AND METHOD VARIATIONS - Tissue visualization device and method variations are described herein where an imaging hood is temporarily sealed against a region of tissue to be treated while under direct visualization. Such a system may include a deployment catheter and an attached imaging hood deployable into an expanded configuration. The imaging hood is placed against or adjacent to the tissue to be imaged in a body lumen that is normally filled with an opaque bodily fluid such as blood. A translucent or transparent fluid is pumped into the hood until the fluid displaces any blood leaving a clear region of tissue to be imaged via an imaging element. Temporary sealing against the tissue can be achieved in a number of ways such as circumferential balloons inflatable within the hood or other sealing techniques. A field of view of the imaging element can be expanded by inflating the balloon beyond the imaging hood. | 01-05-2012 |
20120059394 | CLOSURE DEVICE AND METHOD - Devices and methods for treatment of prolapsed hemorrhoidal arteries is disclosed. The devices can identify the hemorrhoid and ligate the artery without causing significant pain or distension of the rectum. The artery can be identified with ultrasound. The ligation can be performed using energy and/or mechanical structures, such as clips or rubber bands. | 03-08-2012 |
20130131448 | FLOW REDUCTION HOOD SYSTEMS - Flow reduction hood systems are described which facilitate the visualization of tissue regions through a clear fluid. Such a system may include an imaging hood having one or more layers covering the distal opening and defines one or more apertures which control the infusion and controlled retention of the clearing fluid into the hood. In this manner, the amount of clearing fluid may be limited and the clarity of the imaging of the underlying tissue through the fluid within the hood may be maintained for relatively longer periods of time by inhibiting, delaying, or preventing the infusion of surrounding blood into the viewing field. The aperture size may be controlled to decrease or increase through selective inflation of the membrane or other mechanisms. | 05-23-2013 |
20150190587 | VASCULAR ACCESS DEVICE AND GUIDING PORTION - According to various embodiments, a method and system to obtain access to a blood vessel underneath a skin layer that may preserve lifespan of the blood vessel and reduce executional skill variability may be provided. The method includes placing a guiding portion between the blood vessel and the skin layer; and configuring the guiding portion to receive and guide a needle to reach the same location of the blood vessel repeatedly and consistently; and forming a resultant scarred track between the blood vessel and the skin layer as the guiding portion is resorbed over time. The system includes a vascular access device configurable to first possess strength to penetrate through a tissue layer, subsequently possess flexibility to conform to the surrounding tissue beneath the tissue layer; and a guiding portion which may be resorbable, wherein the inlet includes a larger diameter compared to the outlet. | 07-09-2015 |
20160095501 | OFF-AXIS VISUALIZATION SYSTEMS - Off-axis visualization systems are described herein which facilitate the deployment, visualization, and retraction of an imaging element from a catheter. Such a system may include a deployment catheter and an attached imaging hood deployable into an expanded configuration as well as an imaging element, such as a CCD or CMOS imager, which may be deployed from a low profile configuration into a position which is off-axis relative to a longitudinal axis of the deployment catheter and/or imaging hood. | 04-07-2016 |
20160106435 | CLOSURE DEVICE AND METHOD - Apparatus and methods are provided for ligating a hemorrhoidal blood vessel for treatment of hemorrhoids. An exemplary apparatus includes a housing having a distal end insertable into the rectum, an ultrasound sensor, suction channel, and suction port on the distal end; and a compression clip, proximate to the suction port and having two clip arms displaceable from each other, the compression clip having an open configuration within the housing yet biased towards a closed configuration, and wherein the compression clip is deployable in the open configuration and configured to close and compress a tissue segment. | 04-21-2016 |
