    摘要: This patent document discloses perfusion catheters and related methods for treating complications related to CTO interventions or dilating a vessel occlusion while maintaining a passage through the treated vessel segment. A perfusion catheter can include an inflatable balloon coiled in a helical manner around a central axis into a series of windings. An inner surface of the series of windings, when inflated, can define a passage through the inflatable balloon. A catheter can also include an elongate shaft extending from a proximal portion to a distal portion, having an inner surface that defines a lumen for providing inflation fluid to, or withdrawing inflation fluid from, a distal end of the inflatable balloon. A catheter can further include a guidewire support tube including a lumen, separate from the lumen from the elongate shaft and the passage through the inflatable balloon, for receiving a guidewire.

    摘要: Guide extension catheters and related methods are disclosed. A guide extension catheter can comprise an elongate tube member, a push member, and an external manipulation member. The push member can be eccentrically coupled relative to the tube member and extend proximally therefrom for slidably positioning the tube member within and partially beyond a distal end of a guide catheter. The manipulation member can be coupled to a proximal end of the push member, where the manipulation member can be configured to secure the guide extension catheter in place during use by attaching to an external object such that the tube member and push member remain stationary without user engagement.

    摘要: This patent document discloses perfusion catheters and related methods for treating blood vessel lesions and abnormalities. A perfusion catheter can include an inflatable balloon, an elongate shaft operably attached to the balloon, and an optional containment structure surrounding at least a portion of the balloon. The balloon can be inflated until its outer surface contacts a wall of a blood vessel. When inflated, the balloon's inner surface defines a passage for blood to flow. The balloon can be configured to release one or more substances formulated to treat a tissue at or near the wall of a blood vessel. In an example, the balloon can include a bioactive layer, which comprises the one or more substances, overlaying an optional base layer. In an example, the balloon can include multiple filars, at least one of which is configured to elute the one or more substances through a perforation or hole in the filar.
