  • Patent number: 10792471
    Abstract: A delivery sheath includes an elastic outer tubular layer and an inner tubular layer having a thick wall portion integrally connected to a thin wall portion. The inner tubular layer can have a compressed or folded condition wherein the thin wall portion folds onto an outer surface of the thick wall portion under urging of the elastic outer tubular layer. When an implant passes therethrough, the outer tubular layer stretches and the inner tubular layer unfolds into an expanded lumen diameter. Once the implant passes, the outer tubular layer again urges the inner tubular layer into the compressed condition with the sheath reassuming its smaller profile. The sheath may also include selectively placed longitudinal rods that mediate friction between the inner and outer tubular layers to facilitate easy expansion and collapse, thereby reducing the push force needed to advance the implant through the sheath's lumen.

  • Patent number: 10751206
    Abstract: A method for delivering catheters, and stents composed of soft, compliant polymers through anatomical passages. These devices have a bulbous or enlarged anchorage end with a diameter greater than the rest of the catheter. To facilitate implant and delivery a pusher catheter or sheath with an internal lumen larger than the outer diameter of the catheter but smaller than the outer diameter of the bulbous or enlarged anchorage end is provided. The distal end of pusher catheter or the sheath physically engages the proximal end of the bulbous or enlarged anchorage end and applies an axial force to coaxially advance the catheter over a guidewire through anatomical passages. This method allows a physician to move the catheter to an anatomical site without the device exhibiting buckling due to axial force applied. Similarly, this delivery method will allow more force to be applied to the distal end of the catheter diminishing the likelihood of buckling.

  • Patent number: 10426511
    Abstract: A device for detaching parietal thrombi from a bodily vessel is described having a catheter including at least one catheter section with a catheter wall with at least one wall opening which passes completely through the catheter wall. The catheter wall along the least one catheter section is made of a resiliently deformable material in which the at least one wall opening includes a separating helical gap wound around the catheter wall at least in parts along the catheter section. A fixing device permits releasable fixing of the catheter on a bodily vessel so that the catheter can be converted, exclusively by an external mechanical constraint in the form of a torque acting torsionally on the catheter, from a state of smaller catheter outer diameter to a state of larger catheter outer diameter.

  • 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.

    Abstract: A filter system comprises an expandable filter, with a first end of the filter attached to an end of a first tube, and a second end of the filter attached to an end of a second tube. The tubes are arranged telescopically with respect to each other such that telescopic movement of the first and second tubes with respect to each other causes the filter to move between a first collapsed, position and a second expanded position, where the filter extends outwardly. The filter may be a folded-over member, when in the expanded position, or a spiraling member.

  • Patent number: 10299791
    Abstract: Method and apparatus for implanting radially expandable prostheses in the body lumens rely on tacking or anchoring of the prostheses with separately introduced fasteners. The prostheses may be self-expanding or balloon expandable. After initial placement, a fastener applier system is introduced within the expanded prostheses to deploy a plurality of fasteners at least one prosthesis end, usually as each end of the prosthesis. The fasteners are usually helical fasteners which are delivered from a helical track in the fastener applier by rotation with a rotator wire. The fasteners will be applied singly, typically in circumferentially spaced-apart patterns about the interior of each end of the prosthesis.
