  • Publication number: 20080015613
    Abstract: A system and method for endoscopic treatment of tissue is disclosed. An endoscope has an operating channel. A mounting component has a first threading channel that fits into the operating channel of the endoscope. A ligating barrel fits onto a distal end of the endoscope. An elongate medical instrument is inserted through the first threading channel, the operating channel, and the ligating barrel to treat the tissue.

  • Patent number: 5643277
    Abstract: A technique for removing an implanted stent and a device useful therefor. An endoscope is introduced into position at the proximal end of the implanted stent and a cannula is then introduced through the endoscope. A wire guide is then passed through the cannula and into the duct through the lumen of the stent which is to be removed. The cannula is then removed and a stent retrieval cable is advanced over the wire guide and into position at the proximal end of the stent. The stent retrieval cable is torqueable, and has a tapered thread at its distal end and a rotation dial at its proximal end. Once the retrieval cable has been placed into position, the rotation dial is turned to engage the threading into the lumen of the stent. After the stent has been attached to the retrieval cable in this manner, the stent and cable are removed together through the endoscope and out of the body, leaving the endoscope and wire guide in place for use in the implantation of the replacement stent.

  • Patent number: 5176626
    Abstract: An indwelling stent is disclosed which facilitates the drainage of fluids through a duct within the body, and which is easily removed when needed. The disclosed stent is a double wing stent and includes multiple flaps at each end for anchoring and has a continuously uninterrupted drainage tube therebetween. Constructed at the outflow end of the stent is a wick, which is made of an extended arcical section of the drainage tube of the stent and serves to enhance drainage by providing a "wicking" effect for fluid as it exits the stent's outflow end, while inhibiting reflux by allowing for the sphincter at the exit of the obstructed duct to function in a normal manner. The wick further serves to facilitate removal by providing a portion which is easily graspable by an instrument inserted into the body for retention and removal.
