Devices, systems, methods and kits are provided for delivering interventional devices to a target location with a body. Such interventional devices particularly include fixation devices or any devices which approximate tissue, such as valve leaflets. The delivery devices and systems direct the interventional device to the target location through a minimally invasive approach, such as through the patient's vasculature, and provide for manipulation of the interventional device at the target location, such as to approximate tissue. Optionally, the delivery devices and systems may provide for decoupling of the interventional device, allowing the interventional device to be left behind as an implant.

Fixation device delivery catheter, systems and methods of use

Disclosed herein is an articulated guidewire for insertion into a blood vessel. The articulated guidewire includes a rotatable sensor cable, a sensor, a connector, and a satellite wire. The sensor cable has a proximal end and a distal end. A sensor connects to the sensor cable near the distal end and rotates with the sensor cable. The satellite wire attaches to the distal end of the sensor cable and holds the sensor cable in the blood vessel. The connector includes a ball and socket joint which aligns the satellite wire and the sensor cable at a variable angle.

The present invention prolongs the biocidal activity of hydrated lime in a paint or coating by using a sufficient amount of a binder in the paint or coating to block carbon dioxide from reacting with the hydrated lime while still producing a coating that is durable and adhesive upon drying and not unduly friable due to the amount of hydrated lime in said coating.

Biocidal coating composition

An apparatus and method of making a guidewire with a preformed three dimensional profile is described. The Apparatus comprises a mandrel having a screw thread for receiving a core wire and at least one securing means for holding the core wire onto the mandrel. The core wire must be retained under tension in order to properly impart the desired shape into the core wire. A system and method of using the apparatus is disclosed comprising the steps of loading the core wire onto the mandrel, securing the core wire and mandrel and then heating the assembly until the wire takes the desired shape.

Apparatus for making wire with radial expansible guide section and

An athetectomy catheter is disclosed having a composite cutter which is capable of cutting material, including hardened plaque, from a biological conduit. The composite cutter has a cutter and a sensor mount. The cutter has a proximal end and a distal end with a cutting edge. The proximal end of the cutter bonds with the sensor mount. The sensor mount is adaptable for holding a sensor and attaching to a cutter torque cable of an atherectomy catheter. Typically, the atherectomy catheter has a cutter housing with a window. The composite cutter is positioned in the cutter housing and moves in response to movement of the cutter torque cable to cut material from the biological conduit via the window.

Disclosed herein is a cutter capable of removing soft and hard tissue when used with an atherectomy catheter of the type having a cutter housing attached to the distal end of a catheter having a torque cable. A circular cutting blade is disposed within the housing and is secured to the distal end of a rotatable torque cable. An elongated aperture formed along one side of the hosing allows the intrusion of stenotic material which may then be severed by rotating and axially translating the cutting blade. The cutting blade may be made from a cemented tungsten carbide compound of 90 percent tungsten carbide (WC) and 10 percent cobalt (Co) which is heated, injection molded and sintered to produce a hard, durable cutting edge. The cutting edge is coated with titanium carbonitride using a physical vapor deposition process to further increase durability. Cutting edge hardness is further increased by application of an ion implantation of nitrogen using an ion-beam assisted deposition process. A variety of alternative cutter materials, coatings and geometries are defined which improve cutter performance in removing soft and hard lesions.
