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.

Carotid artery stenting systems and methods

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.

Internal carotid artery thrombectomy devices and methods

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 located adjacent the proximal end, a distal port located adjacent the distal end, and a working lumen extending 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 also include a textured surface located along an outer portion of the outer tube and located beneath the inflatable balloon. The elongated sheath may be sized and configured to enable direct insertion into vasculature of a patient through an arteriotomy in at least one of a carotid artery or a vertebral artery to position the inflatable balloon at a target site.

Balloon guiding sheath having a textured surface

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.

Bone expansion systems and methods

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.
