Apparatus and method for closing an opening in a blood vessel using a permanent implant |
摘要 |
An apparatus and method for closing an arteriotomy site is disclosed. The apparatus includes inner and outer frames adapted to sandwich a blood vessel wall therebetween. The inner and outer frames may be manufactured from memory metals such that they can be compressed during the insertion into the tissue tract proximate the arteriotomy site, and then deployed into an expanded configuration larger than the dimensions of the arteriotomy opening itself. A universal joint connects the inner and outer frames to ensure proper pivoting therebetween. In addition, polymeric coverings can be provided on the inner and outer frames to ensure closure, while a collagen plug can also be provided between inner and outer frames to facilitate closure as well. |
