Abstract
Methods and devices for redirecting at least a portion of a fluid from the mesenteric lymphatic system for elimination from the body are disclosed. The fluid may be redirected for elimination through the urinary system or redirected outside the body. The methods and devices disclosed may prevent a portion of a patient's dietary lipids, including cholesterol, from being absorbed, thereby reducing the total caloric load to assist in weight management.
Claims19
A method of treating a patient, comprising:
- introducing a device into a vasculature of the patient, the device having a first end and a second end;
- advancing the device from the vasculature into a thoracic duct of the patient;
- extending the second end of the device through a wall of a cisterna chyli and then through a wall of a kidney, a ureter, or a bladder of the patient to create a fistula between the cisterna chyli and a urinary tract of the patient;
- attaching a portion of the device proximate the first end of the device to the wall of the cisterna chyli;
- and
- attaching a portion of the device proximate the second end of the device to the wall of the kidney, the ureter, or the bladder;
- wherein the device bypasses the vasculature to redirect at least a portion of a fluid from the thoracic duct to the urinary tract to prevent lipids in the fluid from being absorbed in the patient.
4 more elements
A method of treating a patient, comprising:
- introducing a device into a thoracic duct of the patient, the device comprising an inlet and an outlet;
- advancing a portion of the device through a wall of a cisterna chyli, such that the inlet is disposed within the cisterna chyli and the outlet is disposed in a kidney, a ureter, or a bladder of the patient;
- and
- redirecting at least a portion of a fluid from the thoracic duct through the wall of the cisterna chyli to the urinary tract via the device while the inlet of the device is disposed within the cisterna chyli, so that the portion of the fluid bypasses a vasculature of the patient to exit the patient's body with urine.
1 more element
A method of treating a patient, the method comprising:
- implanting a device to create a fistula between a base of a thoracic duct and a urinary tract of the patient;
- and
- redirecting at least a portion of a fluid from the thoracic duct through the device to the urinary tract;
- wherein all of the fluid that enters the device bypasses a vasculature of the patient and is redirected to the urinary tract;
- and
- wherein an inlet of the device is disposed within a cisterna chyli of the patient while redirecting the fluid to the urinary tract.
