  • Patent number: 9848763
    Abstract: An access system includes a proximal handle, an overtube coupled to the handle, and an endoscope port extending through handle and overtube sized for receiving an endoscope therethrough. The overtube includes anatomic wall securing system that secures a distal portion of the overtube within a hole in the anatomic wall. The overtube is provided with a shaped distal portion or a controllably shapeable distal portion that aids in directing an endoscope inserted through the port to a particular location within the peritoneal cavity. The access system includes a system for insufflating/deflating the peritoneal space separately from the body cavity accessible via a natural orifice. The access system includes a closure system to cinch closed the hole made in the anatomical wall after the access system has been removed from the hole. Methods are provided for inserting the access system through the anatomical wall to perform intra-abdominal surgery.

  • Publication number: 20150190166
    Abstract: Instruments, systems and methods are provided for performing submucosal medical procedures in a desired area of the digestive tract using endoscopy. Instruments include a safe access needle injection instrument and a submucosal tunneling instrument, a submucosal dissection instrument, and a mucosal resection device. Systems include a combination of one or more of such instruments with or without injectable agents. Embodiments of various methods for performing the procedures are also provided. In accordance with one aspect there is provided a submucosal implant device for diagnosing and treating disorders of the body. The submucosal implant device may take the form of a gastric stimulator in which signals are supplied to the muscular wall of a mammal to treat motility disorders. In accordance with yet another aspect there is provided a method for performing a submucosal medical procedure to deploy a submucosal implant device in the digestive tract of a mammal.

  • Patent number: 8491472
    Abstract: Instruments, systems, implants, and methods are provided for performing submucosal medical procedures in a desired area of the digestive tract using endoscopy. Instruments include a safe access needle injection instrument, a submucosal tunneling instrument, a submucosal dissection instrument, and a mucosal resection device. A submucosal implant device for diagnosing and treating disorders of the body may be implanted. A passive submucosal implant device may take the form of a drug delivery depot in which a therapeutic agent within the depot elutes from the depot according to a predetermined elution profile. An active submucosal implant device may take the form of a drug delivery device that incorporates a self-contained diagnostic system to determine the appropriate delivery time and dosage of a therapeutic agent to be administered.

  • Publication number: 20090287049
    Abstract: A natural orifice translucent endoscopic surgery (NOTES) comprises a thin, flexible body preferably made from a lubricious film. The port body also includes a coupler to removably attach the port body to an endoscope received through the port body. According to embodiments, the port body also includes a structurally modifiable port body that can be modified while the port body is within the patient. In one embodiment, the port body is constructed with a channel that preferably coils around the port body. The channel can be inflated and deflated to provide relative degrees of rigidity to the port body.

  • Publication number: 20080312495
    Abstract: A minimally invasive method of performing surgical procedures in the peritoneum is provided. The method includes providing a non-lumened flexible visualization scope, a flexible gastric pressurization tube, and at least one additional flexible manipulating instrument, wherein the scope, tube and the instruments are all discrete from each other and all smaller than 2 mm in diameter. The tools are extended into the esophagus and transgastrically through holes defined by incisions or instrument piercing in the stomach wall into the peritoneum, where they are used to visualize, insufflate and perform a peritoneal surgical procedure. Upon removal of the instruments, the holes are substantially self-sealing, and do not require surgical closure. Optionally, a biocompatible glue can be dispensed at the holes to facilitate closure.
