  • Patent number: 10363152
    Abstract: An expandable helical stent is provided, wherein the stent may be formed of an amorphous metal alloy or other non-amorphous metal with a securement. The stent is formed from flat or tubular metal in a helical coiled structure which has an undulating pattern. The main stent component may be formed of a single helically coiled component. Alternatively, a plurality of helically coiled ribbons may be used to form a stent heterogeneous in design, material, or other characteristic particular to that stent. The helical tubular structure may be secured with a securement, such as a weld, interlock or a polymer, to maintain the helical coils in a tubular configuration. The helical coils of the main stent component may be spaced apart or nestled to each other-maintain the tubular shape of the helically coiled stent and prevent the polymer layer from sagging at any point between cycles of the coils.

  • Patent number: 9980803
    Abstract: A retrieval system for a medical device includes an access sheath, a clot catch with an attached mesh, and a filter catch having an attached retrieval member. The filter catch is translatable within clot catch, and the clot catch is translatable within the access sheath. The mesh is expandable into engagement with a body vessel during retrieval of the medical device. The mesh captures emboli that are dislodged during retrieval of the device. The device is captured by the clot catch during retrieval, and the clot catch is subsequently captured by the access sheath. The system can further include an inner sheath translatable within the clot catch, with the inner sheath capturing the medical device and the clot catch capturing the inner sheath.

  • Patent number: 9949853
    Abstract: Flexible implantable devices or stents can navigate tortuous vessels of the neurovasculature. The devices can also conform to the shape of tortuous vessels of the vasculature. In some embodiments, the devices can direct blood flow within a vessel away from an aneurysm or limit blood flow to the aneurysm. Methods and structures are provided for adjusting, along a length of the device, the porosity of the device while maintaining a cross-sectional dimension. In some embodiments, small hooks releasably engage the stent at a proximal end and are able to resheath the stent by retracting a proximal retaining member where the hooks are coupled to. The hooks straighten, unfurl, or otherwise disengage the stent when either unrestrained by a catheter or when coming into contact with an external stimulus found in the patient's vasculature.

  • Patent number: 9901435
    Abstract: Vascular treatment devices and methods include a woven structure including a plurality of bulbs that may be self-expanding, a hypotube, for example including interspersed patterns of longitudinally spaced rows of kerfs, and a bonding zone between the woven structure and the hypotube. The woven structure may include patterns of radiopaque filaments measurable under x-ray. Structures may be heat treated to include various shapes at different temperatures. The woven structure may be deployable to implant in a vessel. A catheter may include a hypotube including interspersed patterns of longitudinally spaced rows of kerfs and optionally a balloon. Laser cutting systems may include fluid flow systems.

  • Patent number: 9877710
    Abstract: A collapsible medical device and associated methods of occluding an abnormal opening in, for example, a body organ, wherein the medical device is shaped from plural layers of a heat-treatable metal fabric. Each of the fabric layers is formed from a plurality of metal strands and the assembly is heat-treated within a mold in order to substantially set a desired shape of the device. By incorporating plural layers in the thus-formed medical device, the ability of the device to rapidly occlude an abnormal opening in a body organ is significantly improved.

  • Patent number: 9878125
    Abstract: A catheter has an entrance opening defined by the first end of a catheter body and non-circular inner surface in cross section. The entrance opening intersects a longitudinal axis extending longitudinally through the center of a lumen adapted to drain urine from a bladder. The non-circular inner surface can have dimples, channels, or grooves, all of which decrease frictional fluid forces against the inner surface as the urine drains. The catheter is free of any eyelets formed in the side wall of the catheter body. The catheter further includes a plurality of distinct longitudinally extending convex outer surfaces and may have an enlarged head.

  • Patent number: 9867617
    Abstract: A surgical instrument includes a handle portion and a body portion extending distally from the handle portion and defining a first longitudinal axis. The surgical instrument includes an articulating tool assembly defining a second longitudinal axis and having a proximal end. The articulating tool assembly is disposed at a distal end of the body portion and is configured to be articulated with respect to the body portion, namely, the articulating tool assembly is movable from a first position in which the second longitudinal axis is substantially aligned with the first longitudinal axis to at least a second position in which the second longitudinal axis is disposed at an angle with respect to the first longitudinal axis. The surgical instrument also includes an articulation mechanism configured to articulate the articulating tool assembly.

  • Patent number: 9855071
    Abstract: A surgical apparatus includes an elongate outer sheath dimensioned for positioning within a body lumen of a patient, a reference member and a removal device. The reference member is adapted for longitudinal movement relative to the elongate outer sheath between a first position at least partially disposed within a longitudinal lumen of the outer sheath and a second position at least partially exposed from the longitudinal lumen. The reference member is adapted to expand when in the second position to generally conform to an internal dimension of the body lumen. The reference member includes a radiopaque material for visualizing the reference member to assist in determining physical characteristics of the body lumen when in the second position. The removal device is adapted for longitudinal movement relative to the reference member, and is configured for disrupting at least a portion of the occlusion within the body lumen.

  • Patent number: 9848975
    Abstract: A method for mechanically capturing and removing a thrombus from a blood vessel includes contacting the thrombus with an inner catheter. A self-expanding body is advanced toward the thrombus, wherein the self-expanding body has a proximal end fixed to a distal end of an elongate catheter. The self-expanding body is preferably made from nickel-titanium and includes a tapered proximal end portion and an open distal end. The self-expanding body preferably has a mesh structure. The self-expanding body is allowed to self-expand in the blood vessel. At least a portion of the thrombus is captured by the self-expanding body and the captured thrombus is then retrieved into a lumen of an aspiration catheter. Negative pressure is applied through the lumen of the aspiration catheter during retrieval of the captured thrombus. A thrombolytic drug may be delivered into the blood vessel before capturing and removing the thrombus.
