Abstract: A polymer of fluorinated monomers and hydrophilic monomers is provided. It is also provided a polymer blend that contains a polymer of fluorinated monomers and another biocompatible polymer. The polymer of fluorinated monomers or polymer blend described herein and optionally a bioactive agent can form a coating on an implantable device such as a drug-delivery stent. The implantable device can be used for treating or preventing a disorder such as atherosclerosis, thrombosis, restenosis, hemorrhage, vascular dissection or perforation, vascular aneurysm, vulnerable plaque, chronic total occlusion, patent foramen ovale, claudication, anastomotic proliferation for vein and artificial grafts, bile duct obstruction, ureter obstruction, tumor obstruction, or combinations thereof.
Abstract: A system for enabling the insertion and removal of an embolic protection device, for capturing and retaining embolic debris which may be created during the performance of a therapeutic interventional procedure in a stenosed or occluded region of a blood vessel. The system, in an embodiment thereof, enables the device to be snap-fitted so as to engage the distal end of a guide wire, to provide a reference for positioning the device at a location distal to the interventional procedure site, and to enable an end of the device to be in tension, enabling a portion of the device to be in tension and another portion to be in compression, so as to assist in bending thereof in tortuous vasculature.

Abstract: A self-expanding cage for use in conjunction with an embolic filtering device includes one or more circumferential members adapted to expand from an unexpanded position to a expanded position within the patient's body vessel. At least one proximal strut and at least one distal strut are attached to the circumferential member to form the basket. The circumferential member may include a plurality of bending regions which enhance the ability of the circumferential member to move between the unexpanded and expanded positions. The proximal and distal struts can be attached to one of the bending regions. When two or more circumferential members are utilized, each member may be connected by a connecting strut which may be connected at a bending region. The connecting strut can be a straight segment or may have a non-linear shape to provide additional flexibility. The expandable cage can be mounted to a elongated member, such as a guide wire, and can be either permanently mounted or rotatably mounted thereto.

Abstract: An intravascular catheter system, such as a dilatation catheter system for angioplasty procedures, which provides for the replacement of the catheter or the guidewire during the procedure. The intravascular catheter has a guidewire-receiving inner lumen extending along its length. A first guidewire port is provided in the catheter body at or near the proximal end of the catheter. A second guidewire port is provided in the catheter body at a location spaced distally from the first guidewire port and proximally from a diagnostic or therapeutic tool, such as a dilatation balloon, on a distal portion of the catheter. A third guidewire port is provided in the distal end of the catheter. The guidewire ports are in communication with the guidewire-receiving inner lumen.

Abstract: A medical device for treating a defective heart valve. The medical device comprises a delivery sheath and an implantable device moveably disposed within the delivery sheath. The implantable device further comprises a distal expandable basket, a proximal expandable basket, and a connecting member coupling at a first end to the distal expandable basket and at a second end to the proximal expandable basket. Each of the distal expandable basket and proximal expandable basket is in a collapsed state during delivery and an expanded state after deployment. An actuator is releasably coupled to the implantable device. When coupled to the implantable device, the actuator can move the implantable device in a way to allow for positioning of the distal and proximal expandable baskets.
Abstract: The invention is directed to an implantable device, such as a stent, for delivering a therapeutic substance. The device includes a reservoir containing a therapeutic substance and an energy converter to cause the release of the substance.
Abstract: Coatings for an implantable medical devices such as stents and methods of fabricating thereof are disclosed. The coatings comprise a biologically absorbable poly(ester amide), which is a polymeric product of a reaction between a diol-diamine and a dicarboxylic acid.

Abstract: Coatings for implantable medical devices and methods for fabricating the same are disclosed. The coatings include a region containing a polycationic peptide, such as, for example, the polycationic peptide known as R7.
Abstract: An embolic protection device for use in a blood vessel when an interventional procedure is being performed in a stenosed or occluded region to capture any embolic material which may be created and released into the bloodstream during the procedure. The device includes a filtering assembly having a self-expanding strut assembly and a filter element attached thereto. In one embodiment, the filtering assembly is attached to the distal end of a guide wire and is deployed within the patient's vasculature as the guide wire is manipulated into the area of treatment. A restraining sheath placed over the filtering assembly in a coaxial arrangement maintains the filtering assembly in its collapsed position until it is ready to be deployed by the physician. Thereafter, the sheath can be retracted to expose the filtering assembly which will then self-expand within the patient's vasculature.

Abstract: The invention relates to devices for the treatment of heart disease and particularly to endo-arterial prostheses, which are commonly called stents. More particularly, the invention relates to methods of manufacturing and coating stents utilizing thermal spray processing (TSP). In one aspect the invention involves the use of TSP for the manufacture of fine grained tubing for subsequent use as a stent or other tubular or ring-based implant, or the manufacture of intermediate sized tubing that may then be drawn to final size tubing and for the coating of a stent. An average grain size of less than 64 microns is achieved by the invention resulting in a stent having an annular wall average thickness of about eight or more grains.

Abstract: An expandable medical device or component thereof including a tubular body formed of a wrapped sheet of porous polymeric material fused together, the tubular body having a fused seam at an angle relative to the longitudinal axis of the tubular body which changes along the length of the tubular body from a first angle to a second angle greater than the first angle. The sheet of porous polymeric material is wound and then fused together such that the winding angle is less in a first longitudinal section of the tubular body compared with the winding angle in a second longitudinal section of the tubular body, in order to provide the second section with greater resistance to expansion (i.e., lower compliance) than the first section.
