Fallopian Tube Occlusion Device

Abstract

A device for occluding the fallopian tube including a retention member and a mesh material supported by the retention member. The retention member has a first lower profile configuration for delivery and a second expanded configuration for placement within the fallopian tube. The mesh material is configured to block passage of an egg through the tube. The member has a plurality of tube engagement members to secure the retention member to the fallopian tube.

1 . A device for occluding the a fallopian tube comprising a retention member and a mesh material supported by the retention member, the retention member having a first lower profile configuration for delivery and a second expanded configuration for placement within the fallopian tube, the mesh material configured to block passage of an egg through the fallopian tube, the retention member having at least one fallopian tube engagement member to secure the retention member to the fallopian tube, the mesh material is a strip of material to form a screen type blocking member to span an opening of the retention member, the retention member having a center point and the mesh material positioned proximal of the at least one engagement member and only distal of the center point of the retention member. 
     
     
         2 . The device of  claim 1 , wherein the mesh is attached to an outer surface of the retention member. 
     
     
         3 . The device of  claim 1 , wherein the mesh is positioned within the retention member. 
     
     
         4 . The device of  claim 1 , wherein the retention member has a plurality of struts defining a space therebetween and the mesh fills a substantial region of the space. 
     
     
         5 . The device of  claim 1 , wherein the strip of material is connected to an inner surface of the retention member. 
     
     
         6 . The device of  claim 5 , wherein the mesh is positioned at a region adjacent the at least one tube engagement member. 
     
     
         7 . The device of  claim 1 , wherein the retention member has a plurality of struts forming a space therebetween and the mesh is positioned to span the space. 
     
     
         8 . The device of  claim 1 , wherein the at least one tube engagement member includes a plurality of teeth. 
     
     
         9 . The device of  claim 1 , wherein the retention member has a plurality of struts and the struts terminate in the at least one tube engagement member. 
     
     
         10 . The device for  claim 1 , wherein the retention member comprises a wound wire. 
     
     
         11 . The device of  claim 1 , wherein the retention member is composed of shape memory material. 
     
     
         12 . A device for occluding a fallopian tube comprising a tube laser cut to form a series of struts, the tube having a first lower profile configuration for delivery and a second configuration for placement, in the second configuration the tube having an expanded configuration, the struts extending outwardly so that a distal region of the struts has a greater dimension and the struts defining a space therebetween, a mesh material supported by the struts and providing a blocking member to block the egg from passage through the fallopian tube, the mesh material is a strip of material to form a screen type blocking member to span an opening of the retention member, the device having a center point, and the mesh material positioned proximal of the at least one engagement member and only distal of the center point. 
     
     
         13 - 14 . (canceled) 
     
     
         15 . The device of  claim 12 , wherein the mesh material is attached to an outer surface of the struts. 
     
     
         16 . (canceled) 
     
     
         17 . The device of  claim 12 , wherein the retention member is composed of shape memory material.
