  • Publication number: 20190366037
    Abstract: A catheter tip having a spring element that imparts longitudinal flexibility, pushability and radial rigidity to the catheter tip, thereby improving deliverability, is provided. The spring element also provides radial support to the distal edge of the catheter tip. The spring element may taper distally, but may have a substantially constant inner luminal diameter. The spring element may be partially covered or embedded, leaving its distal end exposed. The spring element may also include spaced coils in a proximal region. The apparatus may be used with any interventional catheter system, but is particularly suitable for use with balloon-expandable stent systems and balloon-angioplasty systems, where flexibility of the catheter tip and minimal flaring of the distal edge of the catheter tip is desirable.

  • 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.

  • Publication number: 20190209190
    Abstract: The invention provides a thrombus retriever and associated methods for use. The thrombus retriever has a retriever body that is attached to a centrally-disposed deployment member capable of moving the retriever body in the proximal direction (towards the operator) in order to retrieve the target thrombus. The retriever body is attached to the deployment member at an attachment point distal to the most distal end of the retriever body. In use, pulling the deployment member in the proximal direction effectively “pushes” the retriever body from behind during thrombus collection. The thrombus retriever also may comprise a net at its distal end to collect the retrieved thrombus and prevent embolization.

  • Patent number: 10342570
    Abstract: An apparatus, system and method for re-canalization or opening a passage through an occlusion in a blood vessel is provided. The apparatus and method, which are appropriate for cardiovascular and peripheral vessels, use a pulling member and a spring member, for example a compression spring, to oscillate a drilling component. The drilling component at the distal end of the catheter tip has combined longitudinal stiffness for penetrating a total or partial occlusion and high axial (lateral) flexibility to improve deliverability and crossability of a catheter through a partially occluded vessel or a tortuous vessel, and may taper distally. The system of the invention includes the apparatus and a control unit to permit adjustment of the frequency or amplitude of oscillation of the drilling component. Also provided is a method for oscillating a drilling component using a pulling member and a spring member and a method of traversing an occlusion.

  • Patent number: 10251658
    Abstract: An attachment mechanism and method for attaching or coupling a guide wire to a catheter for re-canalization or opening a passage through an occlusion in a blood vessel is provided. The attachment mechanism generates friction forces against the guide wire to couple the guide wire to a catheter, which design permits a greater force to be used on the guide wire during a re-canalization procedure. The invention also encompasses use of the attachment mechanism in conjunction with active catheters, which have vibration-generating means to oscillate the distal end of the catheter or a component in the distal end of the catheter, to add vibration motion, preferably axial vibration motion, to the increased force that may be applied to the guide wire for purposes of penetrating an occlusion. The methods of the invention relate to methods of attaching the guide wire to the catheter and methods of treating a vessel having a partial or total occlusion.

  • Patent number: 10226337
    Abstract: The invention provides a device for fine adjustment of a prosthetic valve device and a method of adjusting the position of a prosthetic valve after implantation. The adjustment mechanism includes complementary structures on a valve member and device frame that cooperate to provide relative axial and/or angular motion between the valve member and device frame (and thus the native vessel). The adjustment mechanism of the invention may also include a means for selectively maintaining the relative position of the valve member and device frame. The device and method are particularly applicable for use with a modular prosthetic valve device that is assembled in the body lumen.

  • Patent number: 9968471
    Abstract: An intravascular stent especially suited for implanting in curved arterial portion. The stent retains longitudinal flexibility after expansion. The stent is formed of intertwined meander patterns forming triangular cells. The cells are adapted to provide radial support, and also provide longitudinal flexibility after expansion. The cells also provide increase coverage of a vessel wall. Loops in the stent are disposed and adapted to cooperate, so that after expansion of said stent within a curved lumen, the stent is curved and cells on the outside of the curve open in length, but narrow in width, whereas cells on the inside of the curve shorten in length, but thicken in width to maintain a density of the stent element area which is much more constant than otherwise between the inside and outside of the curve. The stent also minimizes flaring out by eliminating free loops of the radially supporting circumferential bands of loops.
