Implantable medical devices having controlled surface properties for improved healing response

An implantable medical device that is fabricated from materials that present a blood or body fluid or tissue contact surface that has controlled heterogeneities in material constitution. An endoluminal stent-graft and web-stent that is made of a monolithic material formed into differentiated regions defining structural members and web regions extending across interstitial spaces between the structural members. ... Vactronix Scientific Inc

Implantable expandable medical devices having regions of differential mechanical properties and methods of making same

An implantable expandable medical device in which selected regions of the device are in a martensite phase and selected regions are in an austenite phase. The martensitic regions exhibit pseudoplastic behavior in vivo and may be deformed without recovery under in vivo body conditions. ... Vactronix Scientific Inc

Stents having a hybrid pattern and methods of manufacture

An intravascular stent and method of making an intervascular stent having a hybrid pattern a. 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.. ...

Monolithic biocompatible implantable laminated materials

Metal foils, wires, and seamless tubes with increased mechanical strength are provided. As opposed to wrought materials that are made of a single metal or alloy, these materials are made of two or more layers forming a laminate structure. ... Vactronix Scientific Inc

Grooved drug-eluting medical devices and method of making same

The invention relates to methods and apparatus for manufacturing implantable medical devices, such as intravascular stents, wherein the medical device has a surface treated to promote the migration of endothelial cells onto the surface of the medical device. In particular, the surface of the medical device has at least one groove formed therein, the at least one groove may have a drug-eluting polymer disposed therein or a drug-eluting polymer coating may be provided on the surface of the medical device and grooves formed in the drug eluting polymer coating.. ... Vactronix Scientific Inc

Balloon catheter having metal balloon and method of making same

A metal balloon catheter having a main tubular body, a metal balloon proximate a distal end of the main tubular body, a central annulus extending along an entire longitudinal aspect of the catheter for accommodating a guidewire therethrough and an inflation annulus adjacent the central annulus which extends along the longitudinal axis of the main tubular body and terminates in fluid flow communication with an inflation chamber of the metal balloon. The metal balloon catheter may be either unitary integral metal catheter in which the main tubular body and the balloon are fabricated of metal, or it may consist of a polymeric main tubular body and a metal balloon.. ... Vactronix Scientific Inc

In vivo sensor and method of making same

Implantable in vivo sensors used to monitor physical, chemical or electrical parameters within a body. The in vivo sensors are integral with an implantable medical device and are responsive to externally or internally applied energy. ... Vactronix Scientific Inc

Implantable medical device having enhanced endothelial migration features and methods of making the same

An implantable medical device having enhanced endothelial migration features, generally comprises: a structural member including a leading edge and a trailing edge interconnected by a third surface region, the leading edge including a second surface region in a generally curvilinear cross-section, and the trailing edge including a fourth surface region in a generally curvilinear cross-section, whereby blood flow over the second surface region generate shear stress at the second surface region without an eddy region in the second surface region.. . ...
