  • Publication number: 20210298775
    Abstract: Systems and methods for removal of clot material from vessel lumens are disclosed. A medical device assembly can include a catheter having a lumen and a distal portion configured to be positioned at or adjacent a treatment site within a vessel. An expandable member has a first portion coupled to the distal portion of the catheter, and a second portion extending away from the catheter distal portion. An elongate shaft extends through the lumen of the catheter, and the second portion of the expandable member is releasably coupled to the shaft. When the shaft is slidably moved relative to the surrounding catheter, the second portion of the expandable member can be released from the shaft, and the shaft can be withdrawn or removed.

  • Patent number: 11058444
    Abstract: Retrieval of material from vessel lumens can be improved by electrically enhancing attachment of the material to the removal device. The removal device can have a core assembly that includes a hypotube coupled to a first electrical terminal and a pushwire coupled to a second electrical terminal, the pushwire extending through the hypotube lumen. An insulating layer separates the hypotube and the pushwire, and an interventional element is coupled to a distal end of the pushwire. The interventional element can be disposed adjacent to a thrombus. An electrical signal is delivered to the interventional element to promote adhesion of the thrombus to the interventional element. The electrical signal can optionally be a periodic waveform, and the total energy delivered can be between 0.75-24,000 mJ and the peak current delivered via the electrical signal can be between 0.5-5 mA.

  • Publication number: 20210128160
    Abstract: Treatment of aneurysms can be improved by delivering an occlusive member (e.g., an expandable braid) to an aneurysm sac in conjunction with an embolic element (e.g., coils, embolic material). A treatment system for such treatment can include an electrolytically corrodible core wire having a proximal portion, a distal portion, and a detachment zone between the proximal portion and the distal portion. An occlusive member having a proximal hub is coupled to the core wire distal portion. A conduit extends along at least a portion of the core wire. The conduit has a lumen configured to pass an embolic element therethrough.

  • Publication number: 20210128161
    Abstract: Treatment of aneurysms can be improved by use of a treatment system including a conduit have a distal portion, a coupler slidably coupled to the distal portion, an occlusive member coupled to the coupler, and a securing member coupled to the conduit proximal to the coupler. The securing member can include a distal end portion that is removably coupled to the coupler. In some embodiments, the securing member can have a shape and/or be treated such that the securing member self-expands to decouple itself from the coupler during deployment of the occlusive member. In some embodiments, movement of the conduit relative to the coupler causes the securing member to decouple from the coupler.

  • Publication number: 20210129275
    Abstract: Occlusive devices and associated methods of manufacturing are disclosed herein. Manufacturing an occlusive device can include conforming a mesh to a forming assembly and setting a shape of the mesh based on the forming assembly. In some embodiments, the forming assembly comprises multiple forming members, a mandrel, and/or one or more coupling elements. The method may include everting the mesh over the forming assembly such that the mesh encloses an open volume with a shape based, at least in part, on the shape of the forming assembly. According to some embodiments, setting a shape of the mesh comprises heat-treating the mesh and forming assembly.
