摘要:
A catheter (10) for collecting fluid such as blood from a vessel such as a coronarysinus of a patient has an elongated, flexible tubular portion (12) and an annularsealing member (18) spaced from a distal end of the tubular member. A proximalend of the tubular member is adapted to be connected to a source of suction (111)for applying suction to a collection lumen of the tubular member. The distal end(16) is placed in a blood vessel with the sealing member spaced from opposing surfaceof the vessel in an absence of a suction applied to the collection lumen. Suctionis applied to the collection lumen in an amount sufficient to draw blood from thevessel through the fluid inlet and into the collection lumen and further sufficientto urge the opposing surface of the vessel to migrate into sealing engagementwith the sealing member.
