Devices and methods for attaching support frames to substrates to form articles such as implantable stent grafts can include providing a first laminate material; positioning a support frame onto the first laminate material, the support frame having a pre-formed shape; positioning a second laminate material onto the support frame and first laminate material; bonding the first laminate material to the second laminate material; cutting the first and second laminate materials along opposite sides of the support frame thereby forming a laminated support frame having generally the same pre-formed shape of the support frame; and attaching the laminated support frame to a substrate.

Reinforced angioplasty balloon having an external elastic sheath. The elastic sheath maintains, along its length, a substantially uniform circular cross-section during balloon inflation and forces a deflated balloon into a compacted, substantially circular, wingless profile.

A dental floss comprising a porous PTFE fiber having a density of less than about 0.7 g/cc. The inventive floss is abrasion resistant, grippable and has a soft feel to the hands and a rough feel in the mouth. The floss is made by an extrusion process with non-contact heating during subsequent expansion with amorphous locking.

The present invention is directed to implantable medical device assemblies. The assemblies are primarily used to introduce and deposit implantable medical devices in the vasculatures of implant recipients. The principle implantable medical device used in the assembly is an expandable element in the form of an endovascular device. The expandable element is maintained in a compacted configuration during introduction of the device into the vasculature with a confinement means. The expandable element is released from the confinement means at an implantation site with a control line. The control line has high tensile strength, high modulus, structural rigidity, and low compressibility. These features of the control line provide a practitioner with tactile feedback of the release of the expandable element from the confinement means. The tactile feedback is present during the entire deployment of the expandable element. The tactile feedback enables the practitioner to better track and control deployment of the expandable element at an implantation site.

Implantable medical device assembly

A layered electrode having a large tissue contact area of the portion of the electrode that is electrically active and providing low polarization losses, high pacing impedance and low chronic stimulation voltage. In a fundamental embodiment, the electrode tip has an outer layer of microporous material which is permeable to conductive body fluids which covers a layer of insulating material which is provided with at least one perforation through the thickness of the material. The at least one perforation provides a localized, high current density path. Both of these layers in turn cover the exterior surface of an electrically conductive, preferably metal, electrode body. The present invention is, in a preferred embodiment, a multiple layered device having, in sequence, a) an external layer promoting tissue attachment, b) a cell exclusion layer, which prevents tissue ingrowth into the subsequent underlying layers while allowing passage of conductive fluids, c) a third layer of substantially electrical insulating material with selected or tailored perforations or through holes which provide high current density paths, d) a fourth layer that contains a electrically conductive material of high surface area and e) a fifth metallic layer of a high surface area electrode.
