Zusammenfassung:	This disclosure relates to a catheter with a fluid flow restrictor (e.g., a balloon) that includes a flow path. The catheter is useful for creating, and maintaining, an area of reduced pressure within a blood vessel for removing excess fluid from a patient's body. In particular, the catheter is dimensioned for insertion into a blood vessel and includes a fluid flow restrictor that, when deployed, partially occludes the blood vessel. Pressure is reduced within the blood vessel downstream of the occlusion. The flow path allows some blood to flow past the restrictor, which prevents the blood vessel from stretching due to excessive pressure buildup, thereby allowing the area of reduced pressure to be maintained for extended periods of time.
