Definitions

  • the invention relates to forming anastomoses between two hollow bodies, and more specifically, using magnetic force to form such anastomoses.
  • One embodiment of the invention provides an anastomotic component that is coupled or attached to the wall of a vessel without protruding into the lumen of the vessel or penetrating the vessel wall. That is, substantially none of the anastomotic component or assembly is located within the vessel lumen (i.e., after the anastomosis has been formed). As a result, there is preferably no foreign structure or material disposed within the target vessel lumen after creating the anastomosis.
  • biocompatible adhesive is used to secure a component to the exterior of the target vessel wall without extending into the lumen. This component is coupled to a magnetic or ferromagnetic assembly carried on a graft vessel.
  • Another embodiment uses adhesive to secure the anastomotic components to both vessels.
  • magnetic force is used in combination with an additional locking force, for example, a mechanical connection, to maintain the vessels in proper position and provide heightened resistance to pressure fluctuations that might occur post-formation of the anastomosis.
  • additional locking force for example, a mechanical connection

  • the component 42 is mounted to the exterior of a vessel (not shown), for example, by passing a fastener (also not shown) through each opening 48 into engagement with the vessel tissue.
  • the tabs 46 and openings 48 may be used as secondary securing means, for example, if the component 42 is secured to the vessel by other means, e.g., adhesive.

Abstract

L'invention concerne des méthodes et des dispositifs utilisant la force magnétique pour former une anastomose entre des corps creux. Des anastomoses termino-latérales, latéro-latérales et termino-terminales peuvent être créés sans suture et sans aucun autre type de fixations mécaniques, bien que ces moyens d'attache peuvent être utilisés dans la mise en pratique de certains aspects de l'invention. Des éléments anastomotiques magnétiques (16) peuvent être attachés à l'extérieur d'un vaisseau, par exemple, par un adhésif, sans s'étendre dans la lumière du vaisseau. Différentes configurations d'éléments magnétiques sont prévues et peuvent présenter différentes caractéristiques, par exemple, la capacité de s'adapter à la courbure des vaisseaux ou de venir en contact de frottement avec le vaisseau.
