Abstract
This disclosure relates to a catheter system that for precisely positioning fluid flow restrictors within a blood vessel. In particular, this disclosure provides a catheter system that includes a sheath with a first fluid flow restrictor mounted thereto, and a catheter that is slidably disposed within the sheath and has a second fluid flow restrictor mounted thereto. Inside a blood vessel, the sheath and the catheter are separately slidable, thereby allowing the first and second fluid flow restrictors to be positioned at precise locations within the blood vessel.
Claims30
A catheter system for removing excess fluid, the system comprising:
- a sheath comprising a first restrictor mounted thereto;
- and
- a catheter, slidably disposed within the sheath, the catheter comprising a proximal portion and a distal portion with a second restrictor mounted to the distal portion, thereby allowing the first restrictor and the second restrictor to be independently moveable relative to each another.
A method for treating edema, the method comprising:
- introducing a catheter system into a blood vessel of a patient, the catheter system comprising a sheath comprising a first restrictor mounted thereto and a catheter, slidably disposed within the sheath, the catheter comprising a second restrictor mounted to a distal portion, wherein the first restrictor and the second restrictor are independently moveable relative to each another;
- placing the first restrictor at a first location inside the patient by positioning the sheath;
- and
- placing the second restrictor at a second location inside the patient by sliding the catheter through the sheath.
