  • Publication number: 20210093314
    Abstract: An endoscopic suturing system and method are disclosed as are devices for use with the system and method such as a suture dispenser, a cinch device, and a tissue grasper. In one embodiment the suturing system includes a cap assembly arranged at the distal end portion of an endoscope or guide member, with the cap assembly including a rotatable needle holder. The needle holder is actuated through a transmission element extending outside the endoscope or guide member. A needle capture device may be inserted through a channel of the endoscope or guide member in order to capture a needle held in the needle holder when the needle holder is rotated so that the needle punctures tissue.

  • Patent number: 9867610
    Abstract: A treatment device for use with an endoscope having a instrument channel for passage of an endoscopic instrument and a distal end is provided. The treatment device includes an end effector assembly with a base for placement at the distal end of the endoscope, an end effector rotatable relative to the base, and a mounting portion for attaching the base to the endoscope. The mounting portion is resiliently compressible and can be radially compressed for insertion into the instrument channel, whereby an expansion force of the resiliently compressed mounting portion retains the base relative to the distal end of the endoscope. The mounting portion also includes an opening longitudinally extending therethrough and communicable with the instrument channel and sized for receiving an endoscopic instrument therethrough.

  • 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.

  • Patent number: 9539081
    Abstract: An endovascular valve device for use in a vessel during a therapy procedure includes a catheter having at its distal end a valve. The valve is constructed of a braid of elongate first filaments coupled together at their proximal ends in a manner that the first filaments are movable relative to each other along their lengths. The first filaments have a spring bias that radially expands the valve. A filter is provided to the braid formed by electrostatically depositing or spinning polymeric second filaments onto the braided first filaments. The lumen of the catheter is in communication with the center of the valve. The device is used to provide a therapy in which a therapeutic agent is infused into an organ.
