摘要:
The invention relates to medical devices that has a surface configured to promote the migration of cells onto the surface of the medical device. In particular, the surface of the medical device has a noncontiguous pattern of topographical features formed therein or thereon.
摘要:
An intravascular stent having a hybrid pattern. The hybrid pattern comprises a plurality of circumferentially self-expansible members comprising a plurality of interconnected, geometrically deformable closed cells, adjacent self-expansible members interconnected by a plurality of bridge members linking a first interconnection between two closed cells in a first self-expansible member to a second interconnection between two closed cells in a second self-expansible member, wherein the second interconnection is circumferentially offset and non-adjacent to the first interconnection.
摘要:
The monolithic device comprises a plurality of scaffolding members and a mesh patterned members webbed between the scaffolding members; the mesh patterned member webbed between the scaffolding members surround a lumen and generally expands from a contracted state to an expanded state; and mesh patterned members including a plurality of openings traversing the thickness of the mesh patterned member, and the mesh patterned members including a surface on which a pattern of openings is formed.
摘要:
A transluminal cardiac valve includes an expandable generally tubular cage including when expanded a generally uniform central region, first and second ends each diametrically constricted relative to the central region, a blood impervious region extending from the first end of the cage to within the generally uniform central region, and an inflatable plunger freely disposed and captured within the cage when inflated.
摘要:
A method of manufacturing an endoluminal implantable surface, stent, or graft includes the steps of providing an endoluminal implantable surface, stent, or graft having an inner wall surface, an outer wall surface, and a wall thickness and forming a pattern design into the endoluminal implantable surface, stent, or graft. At least one groove is created in the inner surface of the intravascular stent by applying a laser machining method to the inner surface.
摘要:
The invention relates to methods and apparatus for manufacturing medical devices wherein the medical device has a surface treated to promote the migration of cells onto the surface of the medical device. In particular, the surface of the medical device has at least one topographical feature formed therein.
摘要:
An implantable biocompatible material includes one or more vacuum deposited layers of biocompatible materials deposited upon a biocompatible base material. At least a top most vacuum deposited layer includes a homogeneous molecular pattern of distribution along the surface thereof and comprises a patterned array of geometric physiologically functional features.
