    摘要： A catheter and guide wire assembly (10) for measurement of blood pressure in a living body, comprising: a proximal tube (11) having a distal end and a proximal end; a distal tube (12) having a distal end and a proximal end, which is connected to the distal end of the proximal tube (11); a fluid-permeable coil (13) having a distal end and a proximal end, which is connected to the distal end of the distal tube (12); a distal tip (14), in which the distal end of the fluid-permeable coil (13) is secured; and a core wire (16), which is attached in the proximal tube (11) and which extends through a portion of the proximal tube (11), the distal tube (12) and the fluid-permeable coil (13), and is secured in the distal tip (14), wherein the distal end of the proximal tube (11) and the proximal end of the distal tube (12) are connected by a butt joint and wherein the core wire (16) is glued or brazed to the inner wall of the proximal tube (11) at or close to the butt joint.

    摘要： A method of transarterial embolization agent delivery at a low pressure is provided. The method comprises advancing a delivery device with an occlusion structure in a retracted non-occlusive configuration through a supply artery to a vascular position in the supply artery that is in the vicinity of a target anatomical structure, the target structure having terminal capillary beds, expanding the occlusion structure from the retracted non-occlusive configuration to an expanded occlusive configuration, lowering a mean arterial pressure in a vascular space distal to the expanded occlusion structure, redirecting fluid flow from the collateral vessels toward the lowered pressure vascular space and into the target anatomical structure, injecting an embolization agent through the delivery device and into the lowered pressure vascular space, and delivering the embolization agent from the lowered pressure vascular space into the target anatomical structure. Other catheter assemblies and methods of use are also disclosed.
