  • Patent number: 9629739
    Abstract: A delivery system including a distal capture device that has a sleeve with a passageway defined axially therethrough and one or more elastically deformable sections. Each of the one or more elastically deformable sections has a free terminating end and an opposite end mounted to the distal end of the sleeve. The elastically deformable sections transition between: (i) a fully expanded state in which the elastically deformable section is distally biased in a direction away from the sleeve; and (ii) a retracted state in which the free terminating end of each of the elastically deformable sections is proximally deflected backwards over itself in a direction toward the proximal end of the sleeve.

  • Publication number: 20160317158
    Abstract: An occlusion device for treating an aneurysm can have an inner embolic device with a proximal section and a distal section. The distal section has a first stiffness and the proximal section has a second stiffness. Further, the device has an expandable mesh capable of a collapsed position and an expanded position. The mesh can be disposed over, and attached to, a portion of the proximal section of the inner embolic device. The first stiffness is greater than the second stiffness and the inner embolic device comprises a preselected shape which assists in transforming the expandable mesh from the collapsed position to the expanded position.

  • Publication number: 20160081693
    Abstract: A vasculature occlusion device detachment system including a heating element of a predetermined resistivity. A coil securing suture terminates in a proximal bead retained within the heating element while the distal end of the coil securing suture extends beyond the distal end of the heating element and is attached to the proximal end of the vasculature occlusion device. The coil securing suture is independently rotatable of the heating element 360 degrees about a longitudinal axis extending therethrough the heating element. A power source applies electrical current to the heating element via an electrically conductive corewire and separate insulated electrically conductive wire to increase its resistance and, as a result of the heat produced, sever the coil securing suture.

  • Publication number: 20160038721
    Abstract: A mechanism can include a step feature guidewire having a guidewire with a proximal end, a distal end, and a diameter. A self-expanding element can be disposed approximate to the distal end of the guidewire and can have at least two states which include a contracted diameter and an expanded diameter. The self-expanding element can be expandable under its inherent proprieties, based at least on its original shape and the nature of the materials that make up the element. Further, the expanded diameter can be approximately 70% to 280% of the guidewire diameter. While the guidewire is designed for passing through a body lumen while treating a patient, the expanded diameter is less than any body lumen diameter the guidewire is determined to pass through.

  • Publication number: 20160038150
    Abstract: An embolic device deployment system includes a catheter having a first lumen and proximal and distal ends. A notch is disposed in the first lumen, forming a second lumen. An embolic device has a retaining ring at the proximal end. An engagement member includes a distal loop extending through the retaining ring, and a proximal loop extending into the first lumen. An elongated detachment member can be disposed through the loops and have a detachment member bump disposed between the loops. When the detachment member is disposed within the distal loop and the distal loop is disposed within the retaining ring, the embolic device is engaged. When the detachment member is pulled proximally, the detachment member is withdrawn from the distal loop, and the detachment member bump contacts the proximal loop. These acts assist in the disengagement of the distal loop from the retaining ring to release the embolic device.

  • Publication number: 20150374382
    Abstract: Provided herein are a system, method, and apparatus for delivering a therapeutic device, e.g. an embolic coil, from a delivery tube at a target site in a patient's body. A heating element is disposed in the delivery tube that can be actuated remotely, and a layer of low temperature adhesive is applied at the heating element to retain the therapeutic device. The kicker in the form of, for example, a compressed spring is mounted within the delivery tube so as to be in contact with the therapeutic device for applying a constant ejector force that is countered by the adhesive force of the low temperature adhesive. When the heating element is actuated, the spring's ejector force overcomes the softened adhesive's adhesive force to force the therapeutic device out of the delivery tube.

  • Publication number: 20150297374
    Abstract: A generally tubular braided flow diverting stent is formed of alternating round and rectangular elongated members, for treatment of aneurysms. The generally tubular braided flow diverting stent maintains a significant wall thickness while increasing area coverage of a vessel wall. Sliding of the round elongated members over the rectangular elongated members allows the stent to be crimped to very low diameters for delivery in narrow portions of the vasculature.

  • Patent number: 8932318
    Abstract: Provided herein are a system and method for detaching a therapeutic device, e.g. an embolic coil, from a delivery tube at a target site in a patient's body. The system includes a bead disposed against a distal end of the therapeutic device that retains the therapeutic device to the delivery tube in a first compressed configuration through a series of connectors. The series of connectors include a stretch resistant member through which the bead is attached to an anchor inside the therapeutic device. The anchor, in turn, is disposed against a thermally responsive element comprised of a polymeric material configured to melt or otherwise change configuration to release the anchor, and with it, to also release the bead and therapeutic device. Energy may be supplied to the thermally responsive element through electrical conductors and a resistive heating element disposed within the delivery tube.

  • Patent number: 8920459
    Abstract: An embolic coil detachment system includes an elongated, flexible polymer tube having a tubular wall with an inner surface defining an interior lumen. A distal portion of the tubular wall has a score line, and a resistive heating element is located near the score line and in immediate contact with a surface of a distal portion of the tubular wall, to provide direct heating of the distal portion of the flexible polymer tube adjacent to the score line. A therapeutic embolic coil includes a headpiece that is releasably attached within the distal portion of the flexible polymer tube, and that is releasable by heating of the distal portion of the tubular shaft to cause the distal portion of the tubular wall to split along the score line.
