Abstract

According to exemplary embodiments of the present disclosure, devices, systems, and methods for endoscopic procedures may include an end effector of a grasping system having a first arm and a second arm. The first and second arms may extend from a common proximal joint. The first and second arms may be formed of a self-expanding material and may have a spring force to set the arms in an unconstrained open position. The first and second arms may have an arc shape such that a distal tip of each first and second arm are configured to close as the first and second arms are actuated to a constrained closed position. A catheter may include a locating element at a distal end of a flexible tube. The locating element may be configured for locating the grasping system.

Claims20

Dependent claims

A method for performing an endoscopic procedure on a patient, the method comprising:

inserting a catheter in the patient, a distal end of a catheter being selectively positioned in a small bowel of the patient;
inserting an endoscope in the patient, a distal end of the endoscope being selectively positioned in a stomach of the patient based on the selected position of the catheter in the small bowel;
and
actuating a grasping system to extend an end effector for grasping selected tissue of the small bowel at the selected position of the catheter;
wherein the end effector includes a first arm and a second arm extending from a connection at a proximal end of the first and second arms and movable between an open position and a closed position, wherein the first arm and the second arm are arc shaped and form arcuate shaped tissue-engaging surfaces extending proximally from respective distal tips thereof and facing each other such that the first arm and the second arm are configured for atraumatically closing around the small bowel as the first and second arms are actuated to a closed position to enclose the small bowel atraumatically between the arcuate-shaped tissue-engaging surfaces proximal to the distal tips of the first arm and the second arm.

A method for performing an endoscopic procedure on a patient, the method comprising:

inserting a catheter in the patient, a distal end of a catheter being selectively positioned in a small bowel of the patient;
inserting an endoscope in the patient, a distal end of the endoscope being selectively positioned in a stomach of the patient based on the selected position of the catheter in the small bowel;
and
actuating a grasping system to extend an end effector for grasping selected tissue of the small bowel at the selected position of the catheter, the end effector having a first arm and a second arm extending from a proximal end of the first and second arms to respective distal tips, and movable between an open position and a closed position;
causing the first arm and the second arm to move together to the closed position to atraumatically encompass a portion of the small bowel with only the distal tips of the first arm and the second arm contacting each other, and without pinching the small bowel between the first arm and the second arm;
and
moving the portion of the small bowel encompassed and grasped between the first arm and the second arm proximally.

4 more elements

A method for performing an endoscopic procedure on a patient, the method comprising:

navigating a flexible sheath into a natural orifice of the patient, into the stomach of the patient, and through an opening created in the stomach to grasp the small bowel of the patient;
actuating a grasping system to extend an end effector to grasp a selected portion of the small bowel between a first arm and a second arm of the end effector, the first arm and the second arm extending from a proximal end of the first and second arms to respective distal tips, and movable between an open position, in which the selected portion of the small bowel may be positioned between the first arm and the second arm, and a closed position;
causing the first arm and the second arm to move together from the open position to the closed position to atraumatically encompass the selected portion of the small bowel between arcuate surfaces of the first arm and the second arm, and with the distal tips of the first arm and the second arm contacting each other distal to the selected portion of the small bowel, and without pinching the small bowel between the first arm and the second arm;
and
moving the selected portion of the small bowel encompassed and grasped between the first arm and the second arm.
