  • Publication number: 20190336012
    Abstract: According to one embodiment, a tissue penetrating device includes an elongate shaft having a proximal end, a distal end, and a lumen extending there between. A first needle is disposed within the lumen of the elongate shaft and is extendable therefrom between a first configuration and a second configuration. In the first configuration, the first needle is disposed within the elongate shaft's lumen and is substantially aligned with an axis of the lumen. In the second configuration, the first needle extends distally of the elongate shaft's distal end and bends away from the lumen's axis. A second needle is disposed within a lumen of the first needle and is extendable therefrom when the first needle is positioned in the first configuration and when the first needle is positioned in the second configuration. The second needle may be extended from the first needle to penetrate tissue of a patient.

  • Publication number: 20190307564
    Abstract: A heart implant alignment and delivery device includes an elongate body having an opening that is disposed near a distal end of the elongate body. The opening is configured so that a heart implant is positionable within the opening with the heart implant exposed to a surrounding environment and so that the heart implant is substantially aligned with the distal end of the elongate body. The device also includes an implant reposition member, such as a cable, that is releasably coupleable with the heart implant and that is operationally coupled with the elongate body so that a first operation of the implant reposition member causes the heart implant to be retractably deployed from the opening of the elongate body. The first operation of the implant reposition member may be effected via a handle mechanism that is attached to a proximal end of the elongate body.

  • Publication number: 20190274833
    Abstract: Embodiments described herein include devices, systems, and methods for reducing the distance between two locations in tissue. In one embodiment, an anchor may reside within the right ventricle in engagement with the septum. A tension member may extend from that anchor through the septum and an exterior wall of the left ventricle to a second anchor disposed along a surface of the heart. Perforating the exterior wall and the septum from an epicardial approach can provide control over the reshaping of the ventricular chamber. Guiding deployment of the implant from along the epicardial access path and another access path into and through the right ventricle provides control over the movement of the anchor within the ventricle. The joined epicardial pathway and right atrial pathway allows the tension member to be advanced into the heart through the right atrium and pulled into engagement along the epicardial access path.

  • Patent number: 10285836
    Abstract: The present application describes an implant system useable for positioning an implant device such as a device useful for restricting passage of ingested food into the stomach. In one embodiment, the disclosed system includes a plurality of anchors that may be coupled to tissue within the stomach, or to a tissue tunnel formed by plicating stomach wall tissue. The anchor includes a loop. During use, the implant device is inserted through the loop and expanded such that it retains its position within the loop until removed. Instruments for implanting and explanting the implant device are also described.

  • Patent number: 10219904
    Abstract: Medical devices, systems, and methods reduce the distance between two locations in tissue, often for treatment of congestive heart failure. In one embodiment an anchor of an implant system may reside within the right ventricle in engagement with the ventricular septum. A tension member may extend from that anchor through the septum and an exterior wall of the left ventricle to a second anchor disposed along an epicardial surface. Deployment of the anchor within the right ventricle may be performed by inserting a guidewire through the septal wall into the right ventricle. The anchor may be inserted into the right ventricle over the guidewire and through a lumen of a catheter. An anchor force may be applied within a desired range to secure the anchors about the septum and epicardial surface. The anchor force may inhibit migration of the anchors relative to the septum and epicardial surface.

  • Patent number: 10098773
    Abstract: Described herein is a system for inducing weight loss in a patient, which comprises an extragastric space occupier positionable in contact with an exterior surface of a stomach wall to form an inward protrusion of wall into the stomach, and a retention device positionable in contact with the wall to retain the inward protrusion and to thereby capture the extragastric space occupier within the protrusion.

  • Patent number: 9937043
    Abstract: Embodiments described herein provide devices, systems, and methods that reduce the distance between two locations in tissue, often for treatment of congestive heart failure. For example, an anchor of an implant system may, when the implant system is fully deployed, reside within the right ventricle in engagement with the ventricular septum. The anchor may be deployed into the heart through a working lumen of a minimally invasive access tool. The minimally invasive access tool may have a plurality of grippers near a distal end of the working lumen. The grippers may engage epicardial tissue of the heart and may be moved radially inwardly relative so as to provide stabilization of the epicardial tissue and/or hemostasis near an access site where the anchor is inserted through the epicardium. The minimally invasive access tool may minimize blood loss from the access site and improve anchor implant processes.

  • Publication number: 20170216032
    Abstract: A system for treating a heart includes a catheter that is advanceable into a chamber of the heart and that is repositionable within the chamber between a septal wall and an external wall to enable penetration of the septal and external walls via a needle that is disposed within a lumen of the catheter. A first guidewire is deliverable through the penetration of the septal wall so that a distal end of the first guidewire is disposed within another chamber of the heart. A second guidewire is deliverable through the penetration of the external wall so that a distal end of the second guidewire is disposed externally of the external wall. The first guidewire is connectable to the second guidewire to join or form a path within the chamber that extends between the septal wall and the external wall.
