摘要： 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.

摘要： Systems and methods are provided for treating conditions such as heart failure and/or pulmonary hypertension by at least partially occluding flow through the superior vena cava for an interval spanning multiple cardiac cycles. A catheter with an occlusion device is provided along with a controller that actuates a drive mechanism to provide at least partial occlusion of the patient's superior vena cava, which reduces cardiac filling pressures, and induces a favorable shift in the patient's Frank-Starling curve towards healthy heart functionality and improved cardiac performance. The system may include sensors to determine the degree of occlusion of the superior vena cava. The occlusion system may be used to reduce volume in a heart and facilitate a cardiac procedure. The occlusion system may be used to relieve an overloaded chamber during and/or after deploying a VAD.
