  • Patent number: 12376861
    Abstract: Devices and methods are described for occluding the left atrial appendage (LAA) to exclude the LAA from blood flow to prevent blood from clotting within the LAA and subsequently embolizing, particularly in patients with atrial fibrillation. An implant is delivered via transcatheter delivery into the LAA. The implant includes a conformable structure comprising a foam body and internal support. The support includes anchors that penetrate the foam body and anchor the implant to the walls of the LAA. The implant provides compliance such that it conforms to the native configuration of the LAA.

  • Patent number: 12318293
    Abstract: A system for replacing a heart valve of a patient. The system includes a delivery device and a prosthetic heart valve. The system is configured to be transitionable between a loaded state, a partially deployed state and a deployed state. In the loaded state, the prosthetic heart valve engages a coupling structure and is compressively retained within a primary capsule, which constrains the prosthetic heart valve in a compressed arrangement. In the partially deployed state, the prosthetic heart valve engages the coupling structure and is compressively retained within a secondary capsule, which constrains the prosthetic heart valve to a partially deployed arrangement. The partially deployed arrangement is less compressed than the compressed arrangement and less expanded than a deployed arrangement. In the deployed state, the primary and secondary capsules are retracted from over the prosthetic heart valve, which expands to the deployed arrangement and is released from the coupling structure.

  • Patent number: 12268410
    Abstract: Devices and methods for treating a target site in a body lumen are provided. A medical device includes a stent-like structure including a plurality of scoring and non-scoring filaments interwoven with one another. Generally, the stent-like structure will have more non-scoring filaments than scoring filaments to provide greater structural support and to focus the scoring forces on only a few select areas. The stent-like structure is expanded within the target site to score the target site and to provide temporary structural support while the target site is infused with a therapeutic agent. Such therapeutic agent infusion occurs with the use of a drug eluting or drug coated balloon disposed within the stent-like structure or by occluding the target site and introducing a drug into the occluded target site to sit for a period of time.

  • Patent number: 12213691
    Abstract: A method for removing a clot from a vessel involves the use of a device that can have dual layers where an inner expandable member runs within an outer expandable member. The inner expandable member can be divided into one or more sections, with a proximal section having a clot pinching structure configured to pinch the clot between the pinching structure and an outer catheter. A distal flow channel section of the inner member can be configured to create a flow channel through the clot to restore blood to the downstream vasculature. The struts of the outer expandable member can form closed cells that are not fully circumferential in a proximal portion to allow a clot to pass inside and engage the pinching structure, and fully circumferential in a distal portion to scaffold the vessel for dislodging the clot. A protective element at the distal end of the device can prevent the escape of clot fragments.
