  • Dual lumen guidewire support catheter
    Patent number: 8206370
    Abstract: A dual lumen guidewire support catheter for accurately crossing a chronic total occlusion in a vessel is disclosed. The dual lumen guidewire support catheter includes a first lumen portion and a second lumen portion sharing a common side and a common distal end. The first lumen portion can be a rapid exchange or over-the-wire portion, while the second lumen portion is an over the wire portion. One or both of the portions can include a discontinuity to enable removal of a guidewire following placement through or at an occlusion or lesion.

  • AGENT DELIVERY CATHETER HAVING A RADIALLY EXPANDABLE CENTERING SUPPORT MEMBER
    Publication number: 20120143139
    Abstract: A catheter for delivering an agent to an injection site in a wall of a patient's body lumen, with an elongated shaft having a needle-through lumen slidably containing a needle therein, and an expandable member on the distal shaft section which has a collapsed configuration and a radially expanded configuration. In the radially expanded configuration, the expandable member supports the shaft in a position spaced away from the body lumen wall, and the needle slidably exits the needle-through lumen in the extended configuration through the port spaced away from the body lumen wall as a portion of the expandable member maintains the position of the port section of the shaft in the body lumen. The expandable member typically has an open-walled, helical, or lobed configuration providing a perfusion path along the expandable member.

  • CATHETER HAVING AN AUXILIARY LUMEN FOR USE WITH A FUNCTIONAL MEASUREMENT WIRE
    Publication number: 20120143089
    Abstract: The present invention relates to a surgical catheter, and more particularly, a balloon catheter having an auxiliary lumen configured to permit the advancement of a functional measurement wire to a treatment site. The auxiliary lumen communicates with a working lumen that is configured to permit the advancement of a guidewire and the functional measurement wire, so that the guidewire and functional measurement wire may selectively be advanced to the treatment site during a surgical procedure.

  • RADIOPAQUE INTRALUMINAL STENTS COMPRISING COBALT-BASED ALLOYS CONTAINING ONE OR MORE PLATINUM GROUP METALS, REFRACTORY METALS, OR COMBINATIONS THEREOF
    Publication number: 20120123525
    Abstract: Embodiments are directed to radiopaque implantable structures (e.g., stents) formed of cobalt-based alloys that comprise cobalt, chromium and one or more platinum group metals, refractory metals, or combinations thereof. Platinum group metals include platinum, palladium, ruthenium, rhodium, osmium, and iridium. Here, the term “refractory metals” include zirconium, niobium, rhodium, molybdenum, hafnium, tantalum, tungsten, rhenium, as well as the precious metals silver and gold. In one embodiment, the one or more included platinum group or refractory metals substitute for nickel, such that the alloy is substantially nickel free. The stents exhibit improved radiopacity as compared to similar alloys including greater amounts of nickel.

  • System and method for delivering a stent to a bifurcated vessel
    Patent number: 8167929
    Abstract: A stent delivery catheter system for accurately positioning a stent in a bifurcated vessel is disclosed. The system includes a catheter having a terminal portion and distal tip that is placed in a main branch of the vessel proximate the bifurcation. A fixed guidewire is attached to distal tip. A port is defined in the terminal portion of the catheter. The port is aligned with an ostium of a side branch of the bifurcated vessel to allow the passage of a stent delivery device, such as a balloon catheter having a stent crimped thereon, into the side branch. Radiopaque bands are positioned on opposite ends of the port. A positioning balloon is included on a surface of the catheter opposite the port and is selectively inflatable to position the radiopaque bands adjacent the side branch ostium. The radiopaque bands are referenced to place the stent proximate the side branch ostium.

  • METHODS OF MODIFYING MYOCARDIAL INFARCTION EXPANSION
    Publication number: 20120059355
    Abstract: A reinforcement region is formed within the myocardium by introducing a delivery device through a vessel wall to a treatment site within a myocardium. A biomaterial is then delivered to the treatment site as the delivery device is withdrawn from the treatment site to form the reinforcement regions. Formation of the reinforcement region may further include introducing a delivery device through a vessel wall to a region within a myocardium such that the delivery device is positioned within the myocardium substantially parallel to a wall of the myocardium. A biomaterial may be delivered into a space formed within the region by the delivery device. The reinforcement region may be formed around an infarct tissue region of a myocardium to reinforce the damaged tissue.

  • FLUID BEARING TO SUPPORT STENT TUBING DURING LASER CUTTING
    Publication number: 20120057813
    Abstract: A fluid bearing assembly provides support to stent tubing while the stent tubing is undergoing laser cutting to form a stent pattern. The fluid bearing assembly supports the stent tubing and provides a fluid barrier between the bearing and the stent tubing thereby providing nearly frictionless movement between the support bearing and the stent tubing.
