  • Publication number: 20180028165
    Abstract: The present invention utilizes tetherless microtools to biopsy tissue. The invention provides a device and method for deployment and retrieval of tetherless microtools. The size of the microtools ensures that tissue damage at a site targeted for biopsy is negligible. As such, large numbers of microtools may be deployed ensuring that a true statistical sampling of biologic tissue is performed.

  • Publication number: 20170367723
    Abstract: The present invention is directed to a method of endoscopically ablating/resecting/excluding (A/R/E) the mucosa of the gastric fundus and body. The method of the present invention is intended to cause cellular death to the X/A-like, ghrelin producing and other hormone cells. This is in contrast to present methods to provide only transient ischemia. The use of the method of the present invention results in a more permanent and robust method of reducing ghrelin and other hormone levels. In addition, a method according to the present invention can be used to induce scarring of the gastric fundus which will reduce gastric accommodation of excess food and result in early satiety.

  • Publication number: 20110077662
    Abstract: An implantation device for releasably holding implantable microstimulators can be used to guide one or more microstimulators to any site within the gastrointestinal tract for implantation. The device can further releasably hold one or more ligation clips for securing the one or more microstimulators in place within the implantation site(s) and/or for closing an incision in which a microstimulator is implanted. The device can be employed using open, laparoscopic, and endoscopic techniques.

  • Patent number: 7220253
    Abstract: An adjustable size balloon at the distal end of a feeding tube is used to aid in positioning, along with an endoscope, the tube in the jejunum or small bowel of a patient, without creating an obstruction in the intestines. The balloon is fully inflated when the endoscope that is used to place the tube in the duodenum is withdrawn, and then partially deflated to a size that allows peristaltic action on the balloon to move the tube into the jejunum, after which the balloon is further deflated to avoid creating an obstruction in the intestine.

  • Patent number: 5846235
    Abstract: A cryoprobe instrument for endoscopic use has been provided that permits the delivery of liquid or gaseous cryogens in the form of a spray. In an embodiment, the cryoprobe instrument includes an elongated, flexible tube having a fluid passage defined therethrough; a proximal connector portion provided at the proximal end of the tube for coupling the tube to a pressurized source of cryogenic refrigerant; and a nozzle tip mounted to the distal end of the tube. The nozzle tip has an outlet orifice constructed and arranged such that through the Joule-Thompson effect, cryogenic refrigerant exiting through the outlet orifice rapidly and substantially expands and cools.
