  • Patent number: 11833025
    Abstract: After a prolonged period in the body, an IVC filter can be substantially absorbed by the body. When this occurs, it can be very difficult and/or dangerous for the patient if the IVC filter is forcibly removed. Thus, it is desirable to have systems and methods for safely abandoning the removal procedure of the IVC filter. Example embodiments of an apparatus for safely abandoning the removal procedure of the IVC filter can include: a sleeve having a lumen and a first hole on a wall of the sleeve; a shaft slidably disposed within the lumen of the sleeve; a flexible distal extension comprising a braid structure with a first opening; and a first lasso encircling a portion of the first opening of the braid.

  • Patent number: 11382634
    Abstract: An embolic device and a corresponding embolic device delivery system and method. In one example, an embolic device delivery system comprises a delivery catheter, a coupler disposed inside the delivery catheter, and an embolic device that may be carried and placed by the coupler. The embolic device includes a primary winding that forms a hollow tube such that a coupler may be threaded therethrough. Further, the embolic device may include a slotted metal tube suited to be affixed to one end of the hollow tube formed by the primary winding. Additionally, the embolic device may include a retaining mechanism that includes one or more protrusions suited to engage with one or more slots of the slotted metal tube. In this manner, the retaining mechanism is affixed to the slotted metal tube and the hollow tube formed by the primary winding.

  • Patent number: 11304723
    Abstract: Telescoping, self-driving, and laterally-pushing atherectomy devices are provided, each having a flexible sheath, a cutter with helical flutes, and a drive assembly. The drive assembly can have a flexible driveshaft that is rotatably translational with the lumen of the flexible sheath, a positive displacement pump that begins pumping at the distal end of the drive shaft adjacent to the helical flutes at the proximal end of the cutter, and the flexible drive shaft can be longer than the flexible sheath to enable a reversible telescoping of the drive assembly from the lumen of the flexible sheath. The positive displacement pump can be a screw pump having a drive screw portion extending beyond the flexible sheath, exposed for contact with a vascular lumen for the self-driving. And, the devices can have a reversibly-expandable, lateral pushing member at the distal end of the flexible sheath for the lateral pushing.

  • Patent number: 11116509
    Abstract: A system and method for delivering an embolic device are disclosed. In one embodiment, the system and method may be directed to a combination of a catheter, coupler, and embolic device. The coupler is disposed inside of the catheter. The embolic device is coupled with a retaining mechanism at the proximal end. Until the embolic device is delivered to a certain location within an artery, the embolic device is engaged with the catheter by engaging the coupler with the retaining mechanism. The embolic device is further secured to the delivery catheter by securing the coupler with a securing mechanism formed on the catheter. When the delivery catheter reaches the desired location in the artery, the embolic device is released from the delivery catheter by simply pulling the coupler proximally such that the loop portion of the coupler first becomes disengaged from the locking window and then from the retaining mechanism.

  • Patent number: 11013589
    Abstract: Methods and systems for retrieving temporary Inferior Vena Cava (IVC) filters, other medical implants, or foreign bodies are described. These methods may employ a locking sheath or a proximal-aperture capture feature for IVC filter (or other device) retrieval. One of the methods includes: passing an elongate member having a braided funnel-shaped distal extension through a sheath, where the braided funnel-shaped distal extension includes a distal bend to form a distal aperture and a flap that defines a proximal aperture; passing an end of the medical device through the distal aperture and then through the proximal aperture to capture the medical device; and covering the medical device with the sheath.

  • Patent number: 7238168
    Abstract: An intravascular balloon catheter includes a tubular catheter body having a balloon structure removably mounted over the catheter body. The catheter body has a guidewire lumen, and the catheter body may be left in place within a patient's vasculature while the balloon structure is withdrawn and optionally a second balloon structure introduced over the catheter body. The catheter and methods of the present invention are particularly suitable for performing angioplasty and subsequent procedures, such as stent placement, which are best performed using successive interventional balloon structures.

  • Publication number: 20070142898
    Abstract: The present invention provides improved devices and methods for minimizing and/or inhibiting restenosis and hyperplasia after intravascular intervention. In particular, the present invention provides luminal prostheses which allow for programmed and controlled mizoribine delivery with increased efficacy to selected locations within a patient's vasculature to inhibit restenosis. An intraluminal delivery prosthesis may comprise an expansible structure and means on or within the structure for releasing mizoribine into the body lumen to inhibit smooth muscle cell proliferation.

  • Patent number: 7186237
    Abstract: A balloon catheter for performing an angioplasty procedure on a lesion in a vessel comprising a flexible elongate catheter shaft having proximal and distal extremities. A balloon is secured to the distal extremity of the catheter shaft and has an outer surface extending between proximal and distal extremities of the balloon. A flexible elongate element is provided which extends over the outer surface of the balloon. The flexible elongate element has proximal and distal extremities which are secured about the catheter shaft in positions spaced longitudinally away from the outer surface of the balloon to permit expansion of the balloon and to cause movement of the flexible elongate element into engagement with the lesion to form a longitudinal channel in the lesion.
