Method for hybrid gastro-jejunostomy
View Patent ↗Disclosed herein are methods for joining one piece to tissue to another piece of tissue. In one embodiment, the method can include inserting an applier device having an actuation portion into a first body lumen through a natural body orifice, forming a first opening in a first piece of tissue within the first lumen and a second opening in a second piece of tissue defining a portion of a second lumen adjacent to the first piece of tissue, and inserting the applier device through the first and second openings such that the actuation portion is between the first and second piece of tissue. The method can further include deploying a fastener into the first and second pieces of tissue through the actuation portion of the applier device, thereby joining the first and second pieces of tissue to form an anastomosis between the first and second lumens.
1. A method for joining tissue, comprising:
inserting an applier device into a stomach through a natural body orifice, the applier device having an actuation portion with a fastener disposed thereon;
forming a first opening in a sidewall of the stomach and a second opening in a sidewall of a jejunum;
inserting the applier device through the first and second openings such that the actuation portion and at least a portion of the fastener are between the stomach and the jejunum; and
deploying a first portion of the fastener into the jejunum through the actuation portion of the applier device, and then moving the first portion of the fastener toward the stomach to bring the jejunum into contact with the stomach, and then deploying a second portion of the fastener into the stomach, thereby joining the stomach and jejunum to form an anastomosis between the stomach and jejunum wherein the second and first portions of the fastener respectively comprise proximal and distal ring members joined by a connecting element, the proximal and distal ring members each having a plurality of expandable arms extending therefrom that are adapted to engage tissue.
2. The method of claim 1 , wherein the first and second openings are formed via a laparoscopic surgical procedure.
3. The method of claim 1 , wherein the first opening is formed using a cutting member associated with a distal end of the applier device and the second opening is formed using a cutting element that accesses a site of the second opening by a laparoscopic port.
4. The method of claim 1 , wherein a distal end of the applier device is used as a marker for forming the first opening.
5. The method of claim 1 , further comprising expanding the first and second openings using a tapered distal end of the applier device, such that the applier device can be inserted through the first and second openings.
6. The method of claim 1 , further comprising expanding the second opening using at least one grasping element such that the applier device can be inserted through the second opening.
7. The method of claim 1 , wherein positioning the actuation portion includes positioning the distal ring member of the fastener such that it is adjacent to the jejunum and positioning the proximal ring member of the fastener such that it is adjacent to the stomach, such that the connecting element extends between the jejunum and the stomach.
8. The method of claim 1 , wherein deploying the fastener includes disengaging the fastener from a catch located on the actuation portion that holds the fastener to the actuation portion.
9. The method of claim 1 , wherein the applier device endoscopically accesses a stomach through an esophagus.
10. The method of claim 1 , wherein deploying the fastener includes moving the plurality of arms of the proximal and distal ring members from a first resting position to a second actuated position such that the plurality of arms engage and hold together the jejunum and the stomach.
11. The method of claim 10 , wherein the plurality of arms of the proximal and distal ring members are independently actuated to engage the jejunum and the stomach.
12. A method for forming an anastomosis, comprising:
endoscopically inserting an applier device through a natural body orifice, through a lumen and through a first opening formed in a stomach and a second opening formed in a jejunum;
positioning at least a portion of a fastener disposed on an actuation portion of the applier device between the stomach and jejunum; and
deploying a first portion of the fastener into the jejunum through the actuation portion of the device, then moving the first portion of the fastener toward the stomach to bring the jejunum into contact with the stomach, and then deploying a second portion of the fastener into the stomach to form an anastomosis between the jejunum and the stomach wherein the second and first portions of the fastener respectively comprise proximal and distal ring members joined by a connecting element, the proximal and distal ring members each having a plurality of expandable arms extending therefrom that are adapted to engage tissue.
13. The method of claim 12 , wherein the first and second openings are formed via a laparoscopic surgical procedure.
14. The method of claim 12 , wherein the first opening is formed using a cutting member associated with a distal end of the applier device and the second opening is formed using a cutting element that accesses a site of the second opening laparoscopically.
15. The method of claim 12 , further comprising expanding the first and second openings such that the applier device can be inserted therethrough.
16. The method of claim 15 , wherein deploying the fastener includes moving the plurality of grasping arms of the proximal and distal ring members from a resting position to an actuating position such that the plurality of grasping arms engage the jejunum and stomach.
