  • Patent number: 11147582
    Abstract: Rotational atherectomy devices and systems can remove or reduce stenotic lesions in implanted grafts by rotating one or more abrasive elements within the graft. The abrasive elements can be attached to a distal portion of an elongate flexible drive shaft that extends from a handle assembly that includes a driver for rotating the drive shaft. In particular implementations, individual abrasive elements are attached to the drive shaft at differing radial angles in comparison to each other (e.g., configured in a helical array). The centers of mass of the abrasive elements can define a path that fully or partially spirals around the drive shaft.

  • Patent number: 11110197
    Abstract: Disclosed herein are surgical suture materials that facilitate the sustained delivery of releasable components. The suture materials are processed by the disclosed methods to create a layer of pores extending inward from the outer surface of the suture. Particularly, the surgical suture materials are swollen in a calcium-ion containing solution, then freeze-dried to create pores which can be filled with a releasable component for ultimate delivery to the tissue. In one particular embodiment, the suture has an outer sheath that defines a lumen. Elongated filaments extend through the lumen. This suture embodiment is processed by the disclosed methods to yield a surgical suture material with a porous outer sheath. The pores enable efficient loading of a releasable component into the lumen, facilitating sustained delivery of the releasable component from the suture.

  • Patent number: 11076874
    Abstract: Described herein are low-profile electrodes for use with an angioplasty shockwave catheter. A low-profile electrode assembly may have an inner electrode, an insulating layer disposed over the inner electrode such that an opening in the insulating layer is aligned with the inner electrode, and an outer electrode sheath disposed over the insulating layer such that an opening in the outer electrode sheath is coaxially aligned with the opening in the insulating layer. This layered configuration allows for the generation of shockwaves that propagate outward from the side of the catheter. In some variations, the electrode assembly has a second inner electrode, and the insulating layer and outer electrode may each have a second opening that are coaxially aligned with the second inner electrode. An angioplasty shockwave catheter may have a plurality of such low-profile electrode assemblies along its length to break up calcified plaques along a length of a vessel.
