  • Publication number: 20240108389
    Abstract: A needle-mounted balloon system can include a cannula and a stylet. The cannula may include a handle and an outer sheath, and the outer sheath may be configured to retract and expose at least a portion of an expandable member. The stylet may include a stylet needle and a sharp distal tip portion. The stylet needle may be used to insert the system into a body structure, after which the stylet may be disengaged from the cannula. The expandable member may then be exposed and inflated to create a space in the body structure. Filler material may be injected through the cannula to the open space in an effort to stabilize an injured or otherwise destabilized portion of the body structure.

  • Patent number: 11642143
    Abstract: A balloon guiding sheath may include an elongated sheath comprising a proximal end, a distal end, an inner tube, an outer tube surrounding the inner tube, an access port, a distal port, and a working lumen extending through an interior portion of the elongated sheath between the access port and the distal port. The balloon guiding sheath may also include an inflatable balloon located on an outer surface of the elongated sheath adjacent the distal end. The balloon guiding sheath may include a plurality of inflation holes extending through a side wall of the elongated sheath. The elongated sheath may be sized and configured to enable direct insertion into a patient's vasculature through an arteriotomy in at least one of a femoral artery and vertebral artery to position the inflatable balloon at a target site.

  • Publication number: 20220096257
    Abstract: A carotid artery stenting system can include a sheath that is inserted into an artery. The sheath can include a distal portion having a first inflatable balloon, a first distal port configured to enable a stent to exit the sheath, and a second distal port configured to enable a second inflatable balloon to exit the sheath. A distance between the first inflatable balloon and the second inflatable balloon can be customized by moving a catheter distally or proximally inside a lumen of the sheath.

  • Publication number: 20220062597
    Abstract: The disclosure includes a balloon guiding sheath including an elongated sheath having a proximal end, a distal end, an inner tube and an outer tube both extending between the proximal end and the distal end, an access port located adjacent the proximal end, a distal port located adjacent the distal end, and a working lumen extending through the elongated sheath between the access port and the distal port. The balloon guiding sheath may include an inflatable balloon located on an outer surface of the elongated sheath adjacent the distal end, and at least one vent hole located between an outer surface of the elongated sheath and an inner surface of the inflatable balloon. The at least one vent hole may be configured to allow media to flow from the inflatable balloon to an external portion outside the balloon guiding sheath.

  • Publication number: 20200246036
    Abstract: Embodiments of the invention include tools and methods for performing thrombectomy in patients' internal carotid arteries. A balloon guiding sheath in accordance with embodiments comprises an elongated 7-9 Fr sheath having a working section length of about ninety centimeters, an access port on a proximal end portion and a distal port on a distal end portion. A 6-8 Fr working lumen extends through the sheath between the access port and the distal port. An inflatable balloon is on the distal end portion of the sheath. An inflation lumen extends in the sheath between the balloon and an inflation port. The guiding sheath is configured with stiffness and other characteristics to enable direct insertion of the working length of the sheath into a patient's vasculature through an arteriotomy in the femoral artery, and to position the balloon in the internal carotid artery.
