    Abstract: A fixation mechanism of an implantable lead includes a plurality of depressions of an outermost surface of the lead and a relatively flexible sleeve mounted around the outermost surface. The depressions are spaced apart from one another along a length, and each extends circumferentially, wherein a longitudinal center-to-center spacing between each adjacent depression is uniform along the length, and each depression is of substantially the same size. The sleeve has an internal surface in sliding engagement with the outermost surface of the lead, and an external surface, in which suture grooves are formed. A longitudinal center-to-center spacing between adjacent suture grooves may be substantially the same as, or a multiple of, the longitudinal center-to-center spacing between adjacent depressions of the outermost surface of the lead. The sleeve may also include a ridge protruding from the internal surface, aligned with, or offset (by center-to-center spacing of depressions) from, the grooves.

  • Patent number: 10149697
    Abstract: Devices and methods are provided for percutaneously treating atherosclerotic plaques within blood vessels. Atherosclerotic plaques cause significant morbidity and mortality by narrowing the arteries, which adversely affects blood flow, and by acting as a source for thrombi and emboli thus causing acute organ ischemia. Current treatments include open surgery with its inherent drawbacks, and stenting, which is less invasive but leaves the plaque material in the artery, which promotes restenosis. The present invention combines the advantages of both approaches. In general, the invention provides tools that enable percutaneously dissecting the plaque from the arterial wall and removing it from the body.

    Abstract: An anchoring unit for an implantable lead includes a body, a plurality of anchoring members, and at least one connecting element coupling together at least two of the anchoring members that are positioned adjacent to one another. The body is configured and arranged for positioning along a portion of an outer surface of a lead. The body has a first end, a second end, and a longitudinal axis extending therebetween. The first end is configured and arranged for placement on the lead so that the first end is positioned more distally on the lead than the second end. Each anchoring member has a proximal end and a distal end. The proximal end of each anchoring member extends from the body and the distal end of each anchoring member anchors to patient tissue upon implantation of the anchoring unit into the patient.

  • Patent number: 9579500
    Abstract: A tine portion for an implantable medical device includes a hook segment and a distal segment terminated by a tissue-piercing tip, wherein the distal segment extends from the hook segment to the tip. The hook segment, which is elastically deformable from a pre-set curvature, has one of: a round cross-section and an elliptical cross-section, while the distal segment has a flattened, or approximately rectangular cross-section. One or a pair of the tine portions may be integrally formed, with a base portion, from a superelastic wire, wherein the base portion is configured to fixedly attach to the device, for example, being captured between insulative members of a fixation subassembly.

  • Patent number: 9320891
    Abstract: A lead anchor includes a body with opposing first and second major surfaces and at least one edge surface between the first and second major surfaces. The body defines a first channel, a second channel, and a notch. The first channel extends from the edge surface of the body and is open at the first major surface. The second channel extends from the edge surface of the body and is open at the second major surface. The notch extends from the edge surface of the body, defines an opening from the first major surface through the body to the second major surface, and intersects the first channel and the second channel. The first channel, the second channel, and a portion of the notch define a passage through the body so that a lead can be inserted into the notch and turned to dispose a portion of the lead within the passage. The lead anchor can be part of a kit or system that also includes a lead.

  • Patent number: 9308365
    Abstract: A detachable electrode and anchor utilized with electrode leads and leadless medical implants that enable explantation of the electrode while leaving the anchor in place. The detachable electrode and anchor utilizes a detachable mechanism that detachably couples the electrode to the anchor. Embodiments do not require removal of existing scar tissue before explantation, which minimize chances of internal bleeding at the extraction site. Embodiments also minimize impact on the vein in which the electrode lead travels by eliminating use of a necessarily larger diameter sheath that is utilized around the electrode lead to remove the electrode lead and attached anchor.

  • Patent number: 9283381
    Abstract: A tine portion of an implantable medical device includes a hook segment and a distal segment extending therefrom, wherein the hook segment is pre-set to extend along a curvature and is elastically deformable therefrom to an open position. The distal segment includes a tooth and an end that surrounds the tooth, wherein the end includes a pair of legs and a distal arch. The legs extend along a length of, and on opposing sides of the tooth, and the distal arch extends between the legs, distal to a tissue-piercing tip of the tooth. When the hook segment is in the open position, and a force is applied along a longitudinal axis of the device, to push the distal arch of the distal segment against tissue, for initial tissue penetration, the legs of the end of the distal segment bend in elastic deformation to expose the tissue-piercing tip to the tissue.
