  • Intra-vascular device with pressure detection capabilities using pressure sensitive material
    Patent number: 9066742
    Abstract: A laser catheter with a pressure sensor is provided according to embodiments of the invention. The pressure sensor may be coupled with the distal end of the laser catheter and may comprise any of various piezoelectric materials, for example Polyvinylidene Difluoride (PVDF). In various embodiments of the invention the pressure sensor is configured to detect pressure longitudinally and coaxially. The pressure sensor may provide an electric potential that is proportional to the vessel pressure and may be used to monitor and/or adjust laser parameters. In other embodiments the results from the pressure sensor may be used to determine the vessel size and/or the type of material being ablated.

  • Local delivery of water-soluble or water-insoluble therapeutic agents to the surface of body lumens
    Patent number: 9034362
    Abstract: A method and device for local delivery of water-soluble or water-insoluble therapeutic agents to the surface of a normal or diseased body lumen is disclosed. An expandable structure of a medical disposable device, such as a balloon of a balloon catheter, is coated with an amphiphilic polymer coating comprising a therapeutic agent and an amphiphilic polymer or co-polymer. The medical disposable device is inserted into a body lumen, and expanded to contact the amphiphilic polymer coating against the body lumen. The total solubility of the polymer or co-polymer in vivo prevents any embolic hazard associated with the amphiphilic polymer coating.

  • Tissue separating systems and methods
    Patent number: 9028520
    Abstract: Systems and methods for separating an object such as a pacing lead from a patient tissue involve a flexible and torqueable shaft having an internal lumen sized to receive the object, and a hard separating mechanism for separating the object from the tissue. Typically the shaft and separating mechanism are advanced along or toward the object, and the separating mechanism is contacted with the tissue. The shaft is rotated to effect separation between the object and the tissue. The systems and methods are well suited for use in cardiac pacing or defibrillator lead explant procedures.

  • Retractable separating systems and methods
    Patent number: 8961551
    Abstract: A method for detaching an object from a patient includes providing a tool having a sheath, and a separating assembly operably coupled to a distal end of the sheath. The separating assembly includes a separator moveably coupled to a tip via a threadable connection. The separating assembly is placed near patient tissue that is attached to the object, the sheath is rotated to move the separator distal to the tip, and the separator is applied to the patient tissue that is attached to the object, so as to separate the tissue. A separating system includes a sheath, and a separator threadably coupled with a distal end of the sheath. The separator is adapted to switch between a first configuration where a separating means is deployed, and a second configuration where the separating means is undeployed.

  • Thrombectomy and soft debris removal device
    Patent number: 8920402
    Abstract: A device suitable for removing material from a living being is provided, featuring at least an aspiration pump, powered by a motor. The aspiration pump and any optional infusate pump preferably feature a helical pumping mechanism, and operate at a high rate of rotation, thereby ensuring adequate pumping performance and flexibility. The helical pumping mechanism may be a helical coiled wire about a central core tube. The helical coil wire, whether together with, or independent of, the core tube, may be rotated to cause a pumping action. Additionally, a narrow crossing profile is maintained, ensuring that the device may reach more tortuous regions of the vasculature. In one embodiment, the system comprises a wire-guided mono-rail catheter with a working head mounted on a flexible portion of the catheter that can laterally displace away from the guide wire to facilitate thrombus removal.

  • DISTAL END SUPPORTED TISSUE SLITTING APPARATUS
    Publication number: 20140296897
    Abstract: Methods and systems for separating an object, such as a lead, from formed tissue are provided. Specifically, a tissue slitting apparatus is configured to engage formed tissue at a slitting engagement point. While the object is subjected to a first traction force, the tissue slitting apparatus is caused to move further into the engaged tissue and slit the tissue past the point of engagement. The slitting apparatus causes the tissue to separate along an axial direction of the length of the formed tissue and releases at least some of the force containing the object. The slitting apparatus is supported by a distal end support device configured to lock onto the lead. While supported, a slitting element of the apparatus places fibers of the formed tissue under tension and performs a lifting cut operation. The methods and systems are well suited for use in cardiac pacing or defibrillator lead explant procedures.

  • STABILIZATION DEVICE ASSISTED LEAD TIP REMOVAL
    Publication number: 20140276926
    Abstract: Lead tip removal is accomplished by first stabilizing an area around the lead tip attachment site in the heart wall. A balloon located at the tip of the lead when inflated expands substantially perpendicular to the lead, stabilizing the area around the lead tip. Upon further inflation, the balloon expands substantially parallel with the lead, causing the lead tip to pull away from the heart wall. In another embodiment, a sheath is inserted over the lead and advanced to the heart wall. A passive or active stabilization device is attached to the sheath tip to stabilize the area around the lead tip. In another embodiment, a balloon is located at the tip of the sheath that, when inflated, expands substantially perpendicular to the lead, stabilizing the area around the lead tip. The lead tip is removed with less force due to the stabilization provided to the lead tip area.

  • ASSISTED CUTTING BALLOON
    Publication number: 20140277002
    Abstract: A dilation balloon is wrapped in one or more patterns with a wire or braided material having diamond abrasive or other abrasive material bonded thereto. The wire or braided material is vibrated in one or more ways to enhance the cutting action of the wire abrasive. The wire abrasive may be vibrated using high, low, or even ultrasonic waves transmitted to the wire abrasive via local or remote methods. Alternatively, the dilation balloon may be dilated with a contrast media that exhibits a high absorption to laser light. The contrast material is lased with a laser fiber or fibers inserted into the balloon interior, creating a substantial shockwave that vibrates the balloon and assists in the cracking or abrading of the surrounding plaque in contact with the dilation balloon. The cutting balloon may employ the abrasive coated wires described above or cutting blades.
