  • Patent number: 11491007
    Abstract: A flow diversion device configured in accordance with embodiments of the present technology may include, for example, a housing including openings to channels that intersect at a junction. The flow diversion device may also include, for example, a flow control component disposed at the junction and movable to selectively form pathways for fluid communication based on a position of the flow control component. For example, when the flow control component is in a first position, a first pathway may allow fluid flow causing deployment of the prosthetic heart valve device and, when the flow control component is in a second position, a second pathway may allow fluid flow causing recapture of the prosthetic heart valve device. The flow diversion device may include a handle movable to position the flow control component in the first or second positions thereby selectively controlling fluid flow of the delivery system.

  • Patent number: 11490908
    Abstract: The device disclosed herein is used to the remove a thrombus from the vasculature. It includes an aspiration catheter and a thrombus retrieval device that extends through the lumen of the aspiration catheter. An expandable braided assembly extends over a distal region of the retrieval device, and an activation wire extends through the lumen of the retrieval device to attach to and control the expansion of the braided assembly. Applying tension to the activation wire causes the braided assembly to expand to a diameter of the practitioner's choosing. For example, the practitioner may apply a first level of tension to the activation wire to deploy the braided assembly to a first diameter and then later change the diameter by applying a different level of tension. The expanded braided assembly contacts the thrombus and is pulled proximally toward the aspiration catheter to assist in thrombus removal.

    Abstract: A single integrated intravascular device including a stentriever and semi-compliant balloon housed therein. After traversing a clot, the device is deployed to a self-expanded state engaging the clot therein, whereupon the device along with the embedded clot is removed. Detecting through imaging a stenosis at an original position of the captured clot, the device is reintroduced to that location and the stentriever is deployed to a self-expanded state. Inflating the semi-compliant balloon enlarges the stentriever to a hyper-expanded state greater than the self-expanded state thereby dilating the vessel while simultaneously completely detaching/releasing the stentriever from a remaining portion of the device. Then the semi-compliant balloon is collapsed and withdrawn along with the remaining portion of the device, while the detachable/releasable portion of the stentriever in the self-expanded state remains in the vessel.

  • Patent number: 11109988
    Abstract: Systems and methods for the manufacture of an hourglass shaped stent-graft assembly comprising an hourglass shaped stent, graft layers, and an assembly mandrel having an hourglass shaped mandrel portion. Hourglass shaped stent may have superelastic and self-expanding properties. Hourglass shaped stent may be encapsulated using hourglass shaped mandrel assembly coupled to a dilatation mandrel used for depositing graft layers upon hourglass shaped mandrel assembly. Hourglass shaped mandrel assembly may have removably coupled conical portions. The stent-graft assembly may be compressed and heated to form a monolithic layer of biocompatible material. Encapsulated hourglass shaped stents may be used to treat subjects suffering from heart failure by implanting the encapsulated stent securely in the atrial septum to allow blood flow from the left atrium to the right atrium when blood pressure in the left atrium exceeds that on the right atrium.

  • Patent number: 11045317
    Abstract: Embodiments of an expandable sheath can be used in conjunction with a catheter assembly to introduce a prosthetic device, such as a heart valve, into a patient. Such embodiments can minimize trauma to the vessel by allowing for temporary expansion of a portion of the introducer sheath to accommodate the delivery apparatus, followed by a return to the original diameter once the prosthetic device passes through. Some embodiments can include a sheath with an intermediate layer including an expandable mesh tube, an outer polymeric layer extending over at least a portion of the intermediate layer, and an inner polymeric layer extending within the intermediate layer. The intermediate layer and the inner polymeric layer are configured to establish an enlarged lumen to allow passage of the prosthetic heart valve.

  • Patent number: 10932933
    Abstract: The present teachings provide a medical system for delivering and deploying a medical implant, and the method of using thereof. Specifically, one aspect of the present teachings provides a medical system having an implant with an engagement loop, and a delivery system having an engagement wire and an interface. During implant delivery, the engagement wire engages the engagement loop of the implant. The engagement wire further interacts with the interface in order to prevent unintended disengagement of the engagement loop from the engagement wire. Certain embodiment of the present teaching also includes an implant release control mechanism fixedly attaching to a proximal end of the engagement wire. During implant delivery, the implant release control mechanism attaches the proximal end of the delivery system. During implant deployment, the implant release control mechanism detaches the proximal end of the delivery system.
