  • Patent number: 8740936
    Abstract: A device for pinching an opening in a vessel wall, comprising an introducer sheath, a lumen having a distal opening and a bleed hole; an anchoring having a cylindrical shape in a first constrained state and a flared shape in a second unconstrained state; a pincher member slidably disposed between the anchoring member and the introducer sheath comprising at its distal end a plurality of elongate pincher arms, each of the plurality of elongate pincher arms having a free distal end such that when the pincher member distal end is unconstrained, the free distal ends of the elongate pincher arms are biased to expand radially; and an interior support member slidably disposed in the anchoring member comprising a plurality of elongate support legs, each having a free distal end such that when the distal end of the interior support member is unconstrained, the free distal ends curve outwardly.

  • Patent number: 8663272
    Abstract: Devices and methods for sealing an opening in a blood vessel are disclosed. A device can include: an elongate, tubular non-stick outer sheath, the non-stick outer sheath having a distal end that is insertable into a vessel of a patient through the opening in the vessel wall, and having a proximal end remaining outside the patient; an elongate, tubular non-stick inner sheath disposed within the non-stick outer sheath; and an elongate, tubular adhesive film disposed between the non-stick outer sheath and the non-stick inner sheath, the adhesive film having both inward-facing and outward-facing adhesive surfaces and being supportable by the non-stick inner sheath during insertion into the vessel of the patient.

  • Patent number: 8375553
    Abstract: In one illustrative example, a device for sealing an opening in a vessel wall and/or tissue tract may include an anchor, a filament, a plug, and a knot. The anchor may be configured to be disposed adjacent to an interior surface of the vessel wall adjacent the opening in the vessel wall. The filament may have a distal end coupled to the anchor and may be configured to extend proximally through the vessel opening and/or tissue tract. The plug may be disposed about at least a portion of the filament member. The knot may be disposed about the filament proximal of the plug and may be configured to move over the filament and secure the plug relative to the anchor. The knot may be independent of the filament member.

  • Publication number: 20120259346
    Abstract: The disclosure pertains to a device for cutting a suture in a fluid environment which isolates a portion of the suture to be cut within a substantially sealed environment and cuts the suture thermally by using an electrically heated element within the chamber. In another embodiment, the disclosure relates to a vascular sealing system including the suture cutting device and a method of use thereof.

  • Publication number: 20120065554
    Abstract: A balloon arrangement provided at a distal end of the catheter is configured for deployment within a vessel and comprises a distal balloon and a proximal balloon spaced apart from the distal balloon. An ablation arrangement is provided at the distal end of the catheter and configured to ablate target tissue proximate the vessel. A vessel deformation arrangement comprises at least a portion of the balloon arrangement and is configured to draw a wall segment of the vessel and the target tissue inwardly towards the ablation arrangement. The vessel deformation arrangement may include a port provided in a section of the shaft between the distal and proximal balloons. The port and balloon arrangement are configured to cooperatively draw the wall segment of the vessel and the target tissue inwardly towards the ablation arrangement in response to a negative pressure developed at the port.

  • Publication number: 20080045892
    Abstract: An advancer system is described for moving an elongate medical device within a body. The system includes a drive unit having a motor. The drive unit is configured to translate movement of the motor to the device so as to alternately advance and retract the device relative to the body. The advancer system also includes a user-operable control system configured to control the drive unit. The control system can interface with a magnetic navigation system. The above-described system allows an operating physician to control catheter advancement and retraction while remaining outside an x-ray imaging field. Thus the physician is freed from repeated x-ray exposure.

  • Publication number: 20070239248
    Abstract: Some embodiments of an electrode delivery system may be used to deliver a plurality of wired electrodes into one or more chambers of the heart. In particular embodiments, the plurality of wired electrodes may be delivered into a heart chamber through a single guide sheath device. Such a system may be used to deliver one or more wired electrodes to inner wall of the left atrium, the left ventricle, or both.

  • Publication number: 20070135883
    Abstract: Some embodiments of pacing systems employ wireless electrode assemblies to provide pacing therapy. The wireless electrode assemblies may wirelessly receive energy via an inductive coupling so as to provide electrical stimulation to the surrounding heart tissue. In certain embodiments, the wireless electrode assembly may include one or more biased tines that shift from a first position to a second position to secure the wireless electrode assembly into the inner wall of the heart chamber.

  • Publication number: 20070135882
    Abstract: Some embodiments of pacing systems employ wireless electrode assemblies to provide pacing therapy. The wireless electrode assemblies may wirelessly receive energy via an inductive coupling so as to provide electrical stimulation to the surrounding heart tissue. In certain embodiments, the wireless electrode assembly may be pivotable so that the proximal end of the wireless electrode assembly may be shifted to a position against the heart wall after the distal end has been secured to the heart wall.
