VASCULAR PLUG

摘要

A vascular plug has a frame or skeleton which includes a ring of spring material and, attached to the frame, a cover of impervious or porous material. The plug is able to open a cup configuration when in a deployed condition, so as to provide an occlusion barrier to blood flow. The frame can be radially contracted by twisting into a multi-coiled configuration for deployment through an introducer. The vascular plug has a very short deployment length, making it suitable for deployment in precise locations and is also able to expand to a variety of operating diameters, thereby being suitable for a range of vessel sizes.

主权项

1. A vascular plug including at least one resilient frame element, a cover attached to the at least one resilient frame, the frame element having a first, radially expanded deployed condition and a second, multi-coil configuration in which the coils lie adjacent and substantially coaxial with one another, the frame element being compressible by twisting from the first to the second configuration, wherein when in the second configuration, the plug is not substantially lengthened from the first condition.
