  • Patent number: 10245026
    Abstract: The present invention relates to devices, and methods for using the devices, to create and secure a tissue fold during an endoluminal medical procedure. The devices and methods may be used for folding and securing, for example, a fundus wall onto an esophagus wall or esophageal tissue in the region of the lower esophageal sphincter (LES) to reduce the diameter of the esophagus opening in that region. One aspect of the invention includes forming the tissue fold by closing a grasping arm that is pivotably connected to an overtube that has been positioned at the juncture of the fundus wall and esophagus wall. A further aspect of the invention includes tissue clips configured to be inserted and positioned through an endoluminal device.

  • Patent number: 10201414
    Abstract: An introduction arrangement for a fenestrated or branched stent graft (13) intended for deployment into the lumen of a vessel having a blind vessel extending from it. The introducer (1) has a distal end intended to remain outside a patient in use and a proximal end with a nose cone dilator (11) and an arrangement to retain the branched stent graft distally of the nose cone dilator. A sheath (15) on the introducer extends over the branched stent graft to the nose cone dilator. An indwelling catheter (21) extends from the distal end of the introducer and enters the fenestration or side arm and through to the nose cone dilator, the indwelling catheter has a guide wire (29) extending through it. The guide wire can be extended beyond the nose cone dilator in use before the sheath is withdrawn from the branched stent graft so that it can be snared from the contra-lateral artery.

  • Patent number: 10149676
    Abstract: A device for delivering an implant to a vascular disorder of a patient includes a delivery pusher. A stationary blade may be coupled to the delivery pusher. The stationary blade may include a sharp and stationary cutting component for cutting through a suture coupling the implant to the delivery pusher and for thereby releasing the implant when placed in proximity to the vascular disorder. In some cases, the strength of a junction connecting the suture to the implant is equal to or greater than the tensile strength of the suture itself. Additionally, or alternatively, a detachment handle may be fixedly and permanently attached to the delivery pusher such that a user of the device need not couple the detachment handle to the delivery pusher. The detachment handle may include a user manipulable component for initiating a mechanical release of the implant when placed in proximity to the vascular disorder.

  • Patent number: 10052129
    Abstract: Methods and devices for separating an implanted object, such as a pacemaker lead, from tissue surrounding such object in a patient's vasculature system. Specifically, the surgical device includes a handle, an elongate sheath and a circular cutting blade that extends from the distal end of the sheath upon actuating the handle. The circular cutting blade is configured to engage the tissue surrounding an implanted lead and cut such tissue in a coring fashion as the surgical device translates along the length of the lead, thereby allowing the lead, as well as any tissue remaining attached to the lead, to enter the device's elongate shaft. The surgical device has a barrel cam cylinder in the handle assembly that imparts rotation of the blade and a separate cam mechanism in the tip of outer sheath assembly that imparts and controls the extension and retraction of the blade.

  • Patent number: 10016201
    Abstract: A vascular plug has a frame or skeleton which includes a ring of spring material and, attached to the frame, a cover of impervious or porous material. The plug is able to open a cup configuration when in a deployed condition, so as to provide an occlusion barrier to blood flow. The frame can be radially contracted by twisting into a multi-coiled configuration for deployment through an introducer. The vascular plug has a very short deployment length, making it suitable for deployment in precise locations and is also able to expand to a variety of operating diameters, thereby being suitable for a range of vessel sizes.
