  • Patent number: 10363054
    Abstract: A clot retrieval device for removal of occlusive clot from a blood vessel comprises a clot engaging element 700 having a constrained delivery configuration and an expanded deployed configuration. In the expanded configuration peripheral portions are laterally spaced-apart and the clot engaging section 700 extends between the peripheral portions. The device 700 may have two superimposed wave patterns provided by a large amplitude curve 723 and shorter pitch sinusoidal patterns 721, 722. A wave shape varies the contact pressure between a clot and the device along the length of the device, reducing the compression of the clot by the device at some locations. The device can elongate when placed under tension which aids elongation of the clot during dislodgement.

  • Patent number: 10357276
    Abstract: A medical device includes an expandable-and-contractible member capable of radially expanding and radially contracting, an incising member disposed on an outer circumference of the expandable-and-contractible member and having a hollow portion, a core wire inserted in the hollow portion, a distal tip, and a ring. The core wire is capable of sliding in a longitudinal direction of the medical device as the expandable-and-contractible member expands or contracts. The incising member is therefore not likely to come off upon radial expansion or radial contraction of the expandable-and-contractible member, and is therefore not likely to interfere with the expanding or contracting movement of the expandable-and-contractible member.

  • Patent number: 10299820
    Abstract: The present system is directed in various embodiments to rotational atherectomy systems and methods generally. More specifically, a method for methodically softening and disrupting calcification within the wall of a biological conduit or lumen. This result is achieved by use of at least one eccentric head that, during high-speed rotation within the exemplary lumen, produces a combination of a low-frequency orbital motion comprising a force that is exerted against the lumen wall, with concomitant deflection of same, and a high-frequency pulsatile frequency, also with concomitant exertion of force against the lumen wall and deflection of same. These force-driven deflections produce shockwaves within the layers of the exemplary artery's wall layers, resulting in systematic disruptions of any calcification within the intimal and/or medial layers of the subject artery. In addition, any calcification within the occlusion is also softened and disrupted, increasing compliance of the vessel and/or lesion.

The inner element may comprise an articulable distal assembly configured to core through tissue in an open configuration and part-off cored tissue in a closed configuration. Differential rotation of the inner element with respect to the tubular element causes the articulable distal assembly to selectively assume the open and closed configurations. For example, lagging the rotation of the inner element relative to the rotation of the tubular element may control the articulable distal assembly to assume the open configuration whereas leading the rotation of the inner element relative to the rotation of the tubular element may control the articulable distal assembly to assume the closed configuration.

    Abstract: Angioplasty and other dilatation devices are provided with scoring elements which incorporate a drug to be delivered to a body lumen, typically a blood vessel. The scoring elements have drugs and other active substances coated over a portion thereof or incorporated within internal structure of the element so that the drug is released into the luminal wall closely associated diseased regions of the body lumen as the scoring structure is radially expanded into the wall.

  • Patent number: 10052122
    Abstract: A rotational atherectomy system is disclosed, comprising: an elongated, flexible spin-to-open drive shaft having a distal end for insertion into a vasculature of a patient and having a proximal end opposite the distal end remaining outside the vasculature of the patient; a concentric or eccentric abrasive element, preferably a solid crown, attached to the drive shaft proximate the distal end of the drive shaft; an electric motor rotatably coupled to the proximal end of the drive shaft, the electric motor being capable of rotating the drive shaft in a spin-to-open direction; and control electronics for monitoring and controlling the rotation of the electric motor. When an obstruction at the distal end is detected by the applied torque and/or current reaching a predetermined maximum allowed level and with the drive shaft opened to a maximum allowed outer diameter, power to the motor is eliminated.

  • Patent number: 10022145
    Abstract: A method of removing material from a blood flow lumen generally includes providing a device having a cutting element and an opening, advancing the device through the blood flow lumen to a site where material is to be removed, forcing the opening toward a wall of the site where material is to be removed, and moving the cutting element and the opening so that material in the blood flow lumen is cut by the cutting element and directed into the opening for removal as the cutting element and opening are moved through the blood flow lumen. In some embodiments, the device may be deflected or bent to force the opening toward a wall to remove material. The cutting element may be rotatable and may have an axis that is movable, that is not parallel to the longitudinal axis of the device, or both.

  • Patent number: 10010327
    Abstract: An embodiment of the invention includes an expandable implant to endovascularly embolize an anatomical void or malformation, such as an aneurysm. An embodiment is comprised of a chain or linked sequence of expandable polymer foam elements. Another embodiment includes an elongated length of expandable polymer foam coupled to a backbone. Another embodiment includes a system for endovascular delivery of an expandable implant (e.g., shape memory polymer) to embolize an aneurysm. The system may include a microcatheter, a lumen-reducing collar coupled to the distal tip of the microcatheter, a flexible pushing element detachably coupled to an expandable implant, and a flexible tubular sheath inside of which the compressed implant and pushing element are pre-loaded. Other embodiments are described herein.

    Abstract: A membrane removing forceps may include a first forceps jaw having a first forceps jaw distal end and a first forceps jaw proximal end and a second forceps jaw having a second forceps jaw distal end and a second forceps jaw proximal end. The membrane removing forceps may include one or more abrasive surfaces configured to raise a portion of a membrane. A surgeon may raise a portion of a membrane by grazing the portion of the membrane with one or more abrasive surfaces of a membrane removing forceps. The surgeon may grasp the raised portion of the membrane with the first forceps jaw distal end and the second forceps jaw distal end. The surgeon may then remove the membrane by peeling the membrane apart from an underlying tissue.
