Abstract
An implant for occluding a flow through a vessel may comprise a body member having a first end portion, a second end portion, and an intermediate rod portion extending between the first end portion and the second end portion and a mesh having base layer and a plurality of micro-pillars extending from a first surface of the base layer. The mesh may be disposed about at least a portion of the body such that the micro-pillars extending generally radially outward from the body member. The plurality of micro-pillars may be configured to extend into an adjacent tissue.
Claims19
An implant for occluding a flow through a vessel, the implant comprising:
- a body member having a first end portion, a second end portion, and an intermediate rod portion extending between the first end portion and the second end portion, the intermediate rod portion having an outer diameter less than an outer diameter of the first end portion and an outer diameter of the second end portion;
- and
- a mesh having a base layer and a plurality of micro-pillars extending from a first surface of the base layer, the mesh disposed about the intermediate rod portion such that an inner diameter of the mesh is less than the outer diameter of the first end portion and the outer diameter of the second end portion and such that the micro-pillars extend generally radially outward from the body member;
- wherein the plurality of micro-pillars are configured to extend into an adjacent tissue;
- and
- wherein the body member has a generally solid structure.
A method for delivering an implant to a body vessel, the method comprising:
- advancing a guide catheter and an implant within a body vessel, the implant comprising:
- a body member having a first end portion, a second end portion, and an intermediate rod portion extending between the first end portion and the second end portion;
- and
- a mesh having base layer and a plurality of micro-pillars extending from a first surface of the base layer, the mesh disposed about at least a portion of the body member such that the micro-pillars extend generally radially outward from the body member;
- positioning a distal end region of the guide catheter adjacent to a target region within the body vessel;
- directing a distal opening of the guide catheter towards a side wall of the body vessel;
- distally advancing the implant through the distal opening of the guide catheter towards the side wall of the body vessel;
- and
- compressing an inner surface of the vessel about an outer surface of the implant;
- wherein as the implant is distally advanced through the distal opening of the guide catheter, the plurality of micro-pillars along a portion of the mesh are pushed into the side wall of the vessel.
An implant and delivery system kit, the kit comprising:
- one or more implants, the one or more implants comprising:
- a generally solid body member having a first end portion, a second end portion, and an intermediate rod portion extending between the first end portion and the second end portion, the intermediate rod portion having an outer diameter less than an outer diameter of the first end portion and an outer diameter of the second end portion;
- and
- a mesh having base layer and a plurality of micro-pillars extending from a first surface of the base layer, the mesh disposed about the intermediate rod portion such that the micro-pillars extend generally radially outward from the body member;
- and
- a delivery system, the delivery system comprising:
- a guide catheter defining a lumen extending from a proximal end region to a distal opening;
- and
- a pusher element having an elongate shaft and pusher head positioned at a distal end of the elongate shaft.
