Abstract
Medical devices for implantation in a body vessel, and methods of using and making the same, are provided. A medical device can include a frame with one or more projections each having at least one edge extending from the surface of the frame, and a biocompatible, water-soluble removable material coated over at least a portion of the at least one edge. The projections can be barbs positioned to engage the interior wall of a body vessel or to attach a material, such as a valve leaflet or graft, to the frame. The removable material can be dissolved within a body vessel upon implantation, thereby exposing the at least one edge. Methods of making an implantable medical device and methods of treating a subject are also disclosed.
