Abstract: This invention relates generally to an endoscope accessory. This device uses an overtube with an inflatable positioning balloon that can be inflated after placement of the overtube just proximal to the tip of the endoscope or echoendoscope. This balloon creates a temporary blockade of the gastrointestinal tract proximal to the portion that needs to be examined. The other part of the device is a catheter with an occlusion balloon affixed to its free endportion and can be passed through a passageway within the overtube and extended beyond the tip of the endoscope, distal to the part of the gastrointestinal tract that needs to be examined. Inflation of this balloon together with positioning balloon creates a closed space within the body cavity that can be filled with air or water for improving the quality of the examination with regular endoscope of echoendoscope, respectively, while reducing the examination complications.

Abstract: An assembly for taking a biopsy sample from a site within the body of a patient includes a housing that is positioned over the bedside table of a patient and contains a biopsy actuator assembly used to propel the needles. The biopsy actuator includes a base-frame receiving a cannula slide and a stylet slide, each slide containing a needle holder for propelling the needles with the aid of one spring each. An electrical magnet-triggering device is provided for releasing the stylet slide, which in turn is adapted during the final phase of its propulsion to release the cannula slide. The housing fits to a needle assembly including a flexible guide tube, a flexible cannula and a stylet. The assembly further includes an electrocautery element and a mechanism for adjusting the forward speed and the depth of invasion of the needles.

Abstract: This invention relates generally to a diagnostic and therapeutic device. According to some aspects of the invention, the device may be composed of a flexible sheet that is wrapped around the endoscope shaft to form a flexible overtube. The overtube may include an inflatable positioning ring that may be inflated after placement of the overtube just proximal to the tip of the endoscope or colonoscope to secure the position of the overtube within the body cavity. The overtube also may include an inflatable sealing band within the internal surface of the overtube that when inflated create a seal around the endoscope shaft. According to other aspects of the invention, the device may be a catheter with an occlusion balloon at its free end portion that is carried by the overtube and extends beyond the tip of the endoscope. Inflation of the positioning ring, sealing band and occlusion balloon may define an examination compartment within the body cavity at the tip of the endoscope. The examination compartment may be filled with air, or with water, depending on applications. In addition the examination compartment can be thoroughly lavaged using the irrigation tube system.

Abstract: An elongated flexible sleeve over the endoscope shaft and secured to the endoscope shaft at the proximal portion protects the shaft of the endoscope from touching the external objects before the endoscope shaft is inserted into a body cavity and after the endoscope shaft is withdrawn from the body cavity. In use, the endoscope cover stays outside of the body cavity at the proximity of the body cavity opening at all times. The sleeve may be supplied with a dispenser that releases a lubricant over the endoscope shaft at the tip of the cover during endoscope insertion. The distal end portion of the endoscope cover also may be supplied with an absorbent liner to wipe off secretions and lubricant during endoscope withdrawal.

Abstract: Sanitizing container and display is a sealed but ventable container for removably placing demonstrable objects such as plants, cut flowers, inside the container, living creatures and the like in hospitals, home or other environments where immunocompromised or allergic patients live. This sealed container and display is provided with a ventilation system that establishes adequate air circulation to the inside the container while clearing the outflow air from any potentially harmful microbes, allergens (small particles that cause allergy) or chemical fumes that would be dangerous for those patients who lack normal immune protection or are allergic. This enclosed chamber can optionally be provided with an artificial light source for illumination of the displayed object if desired.

Abstract: An adjustable catheter balloon is composed of an inflatable balloon, a flexible conduit and a handle. The inflatable balloon is attached to the distal end portion of the flexible conduit and the flexible conduit carries therewithin the core wire that moves independently within the flexible conduit and is moved using the handle. The balloon is inflated using a syringe that is connected to the handle which provides a relative movement of the core wire within the flexible conduit translating into changes in the length and contour of the balloon. This allows a diameter decrease of the adjustable catheter balloon and easier passage of the deflated balloon through a narrow working channel of an endoscopic device or a catheter. In addition we would have an increase in the diameter of the inflated balloon inside the body cavity by compressing the balloon longitudinally using the movement of the handle.
