  • Patent number: 8116884
    Abstract: A cardiac ablation device, including a catheter and an expandable ablation element incorporating one or more balloons at the distal end of the catheter, has a continuous passageway extending through it from the proximal end of the catheter to the distal side of the expandable ablation element. A probe carrying electrodes is introduced through this passageway and deploys, under the influence of its own resilience, to a structure incorporating a loop which is automatically aligned with the axis of the expandable ablation device, so that minimal manipulation is required to place the probe. The probe may have an atraumatic tip with a ball formed at the leading edge. The atraumatic tip prevents any tissue damage such as perforation of heart wall.

  • Patent number: 8114148
    Abstract: According to an aspect of the present invention, at least one ionic therapeutic agent is delivered from an implantable or insertable medical device that comprises an ion-conductive polymeric region that is disposed on a metallic region. The metallic region is in electrical contact with a dissimilar metallic region, such that a galvanic current is generated by the dissimilar metals when the device is implanted or inserted into a patient. Delivery of the ionic therapeutic agent from the ion-conductive polymeric region may be, for example, either accelerated or retarded by the galvanic current.

  • Patent number: 8109988
    Abstract: An open frame prosthesis is formed with looped end terminations at its proximal and distal ends. At one end of the prosthesis, the filaments or strands are welded together in pairs to form strand couplings. A plurality of loop segments are connected to the strand couplings, one loop segment for each pair of adjacent strand couplings. In one version of the prosthesis, strands at the opposite end are bent to form looped ends. In another version, loop segments are connected to pairs of strand couplings at both ends of the prosthesis. The loop segments can be connected to the couplings by welding, fusion bonds, or tubes, which are either crimped or heat shrunk.

  • Patent number: 8104427
    Abstract: The present invention is a method and device, which is suitable for use in an operating theater just prior to implantation, for selectively applying a medical coating to an implantable medical device, for example a stent. Disclosed is a device for use with a stent deployed on a catheter balloon. The device is configured to apply a medical coating of a desired thickness to the surface of a stent only. This is done by use of a drop-on-demand inkjet printing system in association with an optical scanning device. The device is further configured so as to, if necessary, apply a plurality of layered coats, each layered coat being of a different coating material, and if appropriate, different thickness. The section of the housing in which the stent is held during the coating procedure is detachable from the housing base. The detachable housing section may be easily cleaned and re-sterilized or simply disposed or simply disposed of.

  • Patent number: 8105274
    Abstract: A catheter is disclosed providing a balloon catheter having a distal tip that is flexible while additionally incorporating high column strength. The present invention additionally provides a distal tip region that accommodates for various sized guidewires. In preferred embodiments, the distal tip region is initially configured for accommodating the passage of 0.12-inch guidewires only. Through specific manufacturing processes, however, the distal tip is modified so that it also may be expanded to accommodate the passage of 0.14-inch guidewires. In additional preferred embodiments, an elastomeric sleeve is disposed over the modified distal tip to allow the tip to return to the initial 0.12 -inch accommodating profile when the larger 0.14-inch guidewire is withdrawn from the catheter.
