摘要： A transatrial intravascular temperature management catheter has a lower heat exchange segment positionable in the inferior vena cava and an upper heat exchange segment positionable in the superior vane cava, with a connecting segment lying between the two and positionable in the right atrium. A temperature sensor on the distal tip of the upper heat exchange segment provides accurate core body temperature signals for feedback purposes since the blood flowing past the sensor has not yet reached the heat exchange segment.

摘要： A patient temperature control catheter includes working fluid supply and return lumens through which working fluid circulates to exchange heat with a patient in whom the catheter is positioned. At least one lumen is defined by plural coils axially spaced from each other. At least a first coil is a large coil that inflates with working fluid to seat against a wall of a blood vessel in which the catheter is positioned, with blood flowing through the coil so as not to block blood flow in the vessel.

摘要： This is directed to containers and methods for holding and delivering vaso-occluding materials such as hydrogel particles and filaments. The vaso-occlusive materials may be held in the container in a hydrated or unhydrated state. The container includes a fluid ingress port and a fluid egress port that are respectively fluidly connectable with a fluid source and a delivery catheter. The container further includes at least one chamber or passageway extending therebetween. The passageway may be straight, curved, spiral, helical, narrow or otherwise shaped. The chamber may also have sections of varying cross section such as a ramped section. The shapes of the passageways of the container help organize ejection of the vaso-occluding materials minimizing contamination and clumping. Methods for holding and introducing the materials are also provided.
