Methods and devices for removing omental tissue
View Patent ↗The invention relates to a method of treating obesity, insulin resistance and co-morbidities of these conditions by removing tissue from the abdomen. More specifically, it relates to a method of removing abdominal fat and omentum to which the fat is attached, in order to improve health. The invention includes a device for safely removing this tissue material
1. A method of removing a portion of omentum tissue from a human body, the method comprising:
securing the omentum tissue to a shaft;
rotating the shaft to affix a portion of omentum tissue about the shaft;
separating the omentum tissue from the human body while the portion of the omentum tissue is affixed to the shaft; applying energy to the portion of omentum tissue to cauterize or coagulate the portion of omentum tissue to reduce bleeding; and removing the portion of omentum tissue from the body.
2. The method of claim 1 , where securing the omentum tissue to the shaft comprises drawing a vacuum through an opening in the shaft to temporarily secure the omentum tissue about the opening.
3. The method of claim 1 , further comprising creating an incision in the body and where removing the portion of omentum from the body comprises removing the portion of the omentum through the incision.
4. The method of claim 1 , where applying energy to the portion of omentum tissue comprises advancing a loop electrode around the portion of omentum tissue and energizing the loop electrode to separate the omentum tissue.
5. The method of claim 1 , where applying energy comprises applying an energy source selected from the group consisting of RF energy, coherent light, incoherent light, and resistive heat.
6. The method of claim 1 , where securing the omentum tissue to the shaft occurs as the shaft beings rotating.
7. The method of claim 1 , where rotating, the shaft causes a vacuum source to draw a vacuum through an opening in the shaft to pull the omentum tissue within the opening.
8. The method of claim 1 , further comprising advancing an access device into a stomach of the body, creating an incision in the stomach and removing the portion of omentum from the body through the incision.
9. The method of claim 1 , further comprising creating an incision in an abdominal wall and removing the portion of omentum from the incision in the abdominal wall.
10. The method of claim 1 , further comprising placing a visualizing, device into the abdominal cavity.
11. The method of claim 1 , further comprising morselizing the portion of omentum tissue after or during separating the omentum tissue from the body.
12. The method of claim 1 , where separating the omentum tissue is performed by a process selected from the group consisting of heating, mechanically cutting and electrically cutting the portion of tissue.
13. The method of claim 1 , where rotating the shaft to affix the portion of omentum tissue about the shaft further includes placing the portion of omentum tissue in a state of traction.
14. The method of claim 1 , where removing the separated portion of omentum tissue from the body comprises applying a vacuum to the portion of omentum tissue.
15. The method of claim 1 , where securing the portion of omentum tissue comprises advancing a retrieval device through the incision, where the retrieval device comprises a distal end, securing the portion of omentum tissue to the distal end and at least partially drawing the portion of omentum tissue into the distal end.
16. The method of claim 15 , further advancing an electrosurgical component over the drawn portion of omentum tissue and applying the energy through the electrosurgical component to the portion of omentum tissue.
17. The method of claim 15 , further comprising applying a vacuum through the retrieval device to secure the portion of omentum tissue to the distal end.
18. The method of claim 17 , where the retrieval device farther includes a valve, and where applying the vacuum through the retrieval device further comprising actuating the valve to apply the vacuum.
19. The method of claim 1 , where the incision is made in an organ selected from the group consisting of the colon, uterus, small intestine and large intestine.
20. The method of claim 1 , further comprising removing abdominal fat, visceral fat, and abnormal tissue through the incision.
21. The method of claim 1 , wherein separating the omentum tissue and cauterizing or coagulating the omentum tissue occurs simultaneously.
