  • Patent number: 8920457
    Abstract: A vascular occlusion device for use with a hydraulic deployment catheter is provided. The vascular occlusion device includes a headpiece that has a deformable interference element which changes from an initial configuration to a deformed configuration upon an increase of hydraulic pressure within the deployment catheter. When the interference element is in the initial configuration, the headpiece is secured to the deployment catheter, and when the interference element is in the deformed configuration, the headpiece can be removed from the deployment catheter for deployment of the occlusion device.

  • Patent number: 8313504
    Abstract: The present invention relates to a medical device for placement at a predetermined location within a passageway of the human body, and more particularly, relates to a flexible embolization device which may be delivered by a catheter to a pre-selected position within a blood vessel to thereby embolize a blood vessel or a blood vessel defect, such as an aneurysm or fistula. Specifically, the embolization device comprises an elongated coil having a lumen, the coil and lumen being at least partially embedded in an elongated foam member comprising, in some embodiments, a flexible, biodegradable, water insoluble, open, interconnecting-cell foam material having embolic characteristics, and capable of allowing cell proliferation into the open cell foam interior.

  • Patent number: 8211141
    Abstract: A vasoocclusive embolic delivery system for use in placement of an embolic coil at a treatment site within a vessel. The embolic coil includes an elongated stretch resistant fiber having its distal end bonded to the distal end of the embolic coil. The stretch resistant fiber extends through a central lumen of the coil and extends beyond the proximal end of the coil. Also included is a generally cylindrical stabilization bead, having a diameter slightly smaller than the diameter of the central lumen of the coil, mounted on the stretch resistant fiber within the lumen of the embolic coil. The stabilization bead serves to keep the stretch resistant fiber centered within the lumen of the embolic coil. Additionally, a headpiece is mounted on the proximal end of the stretch resistant fiber and serves to couple the embolic coil to the delivery system.

  • Patent number: 8034073
    Abstract: A vasoocclusive embolic device deployment system for use in the placement of an embolic coil at a treatment site within a vessel. The embolic coil includes an elongated stretch resistant fiber having one distal end bonded to the distal end of the embolic coil. The stretch resistant fiber includes portions which take the form of periodic undulations separated by portions which are straight. The stretch resistant fiber extends through the lumen of the coil and the other distal end is bonded to the proximal end of the coil. The stretch resistant fiber may be attached to the embolic coil at additional points between the proximal and distal ends of the coil. Additionally, a headpiece is mounted on the proximal end of the embolic coil and serves to couple the embolic coil to a deployment catheter.

  • Patent number: 7708755
    Abstract: A medical device for placing an embolic device at a predetermined site within a vessel of the body including a delivery catheter and a flexible pusher member slidably disposed within the lumen of the catheter. A fluid pressure source is coupled to the proximal end of the pusher member. An embolic device is retained at the distal end of the pusher member by a mechanical interlocking mechanism. The distal end of the pusher member includes a spiral ribbon section encircled by a tubular member. The tubular member or the distal end of the pusher member directs fluid from the fluid pressure source against the embolic device. The mechanical interlocking mechanism is disengaged from the embolic device and a fluid pressure is applied against the embolic device to ensure the release of the embolic device.

  • Patent number: 6685707
    Abstract: A clamp assembly for repairing a bone defect according to the invention includes a base, a cap opposing the base, and a post connecting the cap and the base in a fastening position on adjacent bone plate and surrounding cranium. The clamp assembly may further include an applier interacting with the post to position the cap and base in the fastening position. A method according to the invention includes placing the base and cap on opposing internal and external surfaces of the bone plate, with a portion of each of the base and cap overlapping a border of junction between the bone plate and surrounding bone. The post is rotated to bring the base and cap to the fastening position. The method may further include removing a distal portion of the post projecting from the cap and leaving a proximal portion of the post projecting from the cap and which can be deformed to secure the base and cap in the fastening position.
