Abstract: A catheter may be used for treating chronic venous insufficiency (CVI) by remodeling a venous valve within a vein. The catheter is advanced through the vein to a position proximate the venous valve, the catheter including a hollow needle extendable out a first side wall of the catheter and an inflatable balloon located on a second, opposing, side wall of the catheter. The inflatable balloon is inflated in order to urge the catheter towards a vessel wall opposite that of the inflatable balloon. The hollow needle is advanced at least partially into the vessel wall opposite that of the inflatable balloon and a bulking agent is injected near the venous valve in order to remodel the venous valve. The bulking agent may be injected within a subintimal space within the vessel wall, or into an advential space outside of the vessel wall.

Abstract: A balloon for renal nerve modulation is disclosed. The balloon may include a polymer material forming a balloon wall having an outer surface and flexible circuits comprising a base selectively adhered to the exterior surface of the balloon wall. Adhesive is selectively applied to the outer surface of the balloon, to the flexible circuit or to both such that the adhesive is selectively deposited on the at least a portion of the at least two pads or on the at least a portion of the at least two pads and to a portion of the distal spline. The portion of the at least two pads or the portion of the at least two pads and a portion of the distal spline are adhered to the outer surface of the balloon and a remainder of the flexible circuit moves freely with respect to the outer surface of the balloon.

Abstract: Embodiments of a deployment system may include a catheter having a distal end and a proximal end. An actuator may be disposed at the distal end of the catheter and may be operatively connected to electrical connectors extending longitudinally along the catheter from the proximal end to the actuator. The electrical connectors may be configured for transmission of signals to the actuator. One or more connections may be coupled to the actuator and to a deployable medical device disposed at the distal end of the catheter.

Abstract: The present disclosure relates generally to devices, systems, and methods for coil embolization, and, more particularly, to use and methods of forming coated coils. In an aspect, an embolic system may include a coil having a proximal end, a distal end, and a length therebetween slidingly disposed within a sheath. A coating may be disposed about the coil. A delivery filament may be configured to be slidingly disposed within the sheath proximal of the coil such that the coil can be ejected from the distal end of the sheath into the working lumen of a microcatheter. The coating may be configured to substantially fracture as the coil transitions from being substantially aligned with a longitudinal axis of the microcatheter to substantially misaligned with the longitudinal axis of the microcatheter upon being ejected from the microcatheter. The coating may be configured to plasticize after being ejected into an aqueous environment.

Abstract: Locking catheters including a fluid-tight hub and mechanism to secure a flexible member. An illustrative locking catheter may comprise an elongate shaft defining a lumen, a first connection member coupled to the elongate shaft, a second connection member configured to be releasably coupled to the first connection member, and a flexible member extending through at least a portion of a lumen of the elongate shaft and a portion of a lumen of the first connection member. The proximal end of the flexible member may extend through the aperture of the first connection member such that the proximal end of the flexible member is exterior to the first connection member. When the second connection member is coupled with the first connection member, the flexible member may be secured between an inner surface of the first connection member and an outer surface of the inner tubular member of the second connection member.

Abstract: Medical devices, medical device systems, and methods for using the same are disclosed. An example medical device system may include a guide catheter having a proximal end, a distal end, and a lumen extending therebetween. The guide catheter may be designed to guide a therapeutic catheter to a target site. A guidewire may be disposed within the lumen of the guide catheter. The system may also include a trap balloon catheter including a catheter shaft and a balloon coupled to the catheter shaft. The trap balloon catheter may be designed to extend through the lumen of the guide catheter to a position adjacent to the distal end of the guide catheter. A trap balloon retainer may be coupled to the catheter shaft. The trap balloon retainer may be designed to prevent a distal end of the trap balloon catheter from extending distally beyond the distal end of the guide catheter.
