摘要：<p>An occluder apparatus (10) for obstructing the flow of blood in a blood vessel has an elongated hollow tubular body (12) having a leading end sized for reception in the blood vessel and includes a portion of the body fabricated from a material soluble in blood, and a piercing device for inserting the body through the wall of the blood vessel to extend the leading end into the interior of the blood vessel. An inflatable diaphragm (54) is carried by the body in a collapsed, deflated condition, and the apparatus includes a passage for conducting an inflating fluid from an external source, which is into fluid communication with the interior of the diaphragm, to effect expansion of the diaphragm. Elongated openings (53, 55, 57) in the body enable the diaphragm to be released in an inflated state from the body into flexible occluding engagement with the interior wall of the blood vessel about the full circumference of a transverse section thereof.</p>
