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.

Flexible circuit having improved adhesion to a renal nerve modulation balloon

An accessory device may be used in combination with a thrombectomy catheter. The accessory device may be configured to deflect a distal portion of the thrombectomy catheter and/or disrupt a lesion in a vessel.

Accessory devices for use with catheters

A medical device and related methods of use or manufacture are disclosed. The medical device may include an intravascular catheter for nerve modulation. The medical device includes an elongate shaft having a proximal end region, a distal end region, and a lumen extending therebetween. An expandable member is coupled to the distal end region of the elongate shaft. One or more electrical conductors extend from the proximal end region of the elongate shaft to the expandable member. The one or more electrical conductors may have a distal end region secured directly to an outer surface the expandable member. One or more energy delivery regions are positioned on the expandable member and coupled to the one or more electrical conductors.

Balloon catheters with flexible conducting wires and related methods of use and manufacture

Medical devices and methods for making and using medical devices are disclosed. An example medical device may include a catheter shaft. An expandable balloon may be coupled to the catheter shaft. The balloon may be capable of shifting between a folded configuration and an expanded configuration. A support structure may be coupled to the balloon. The support structure may be capable of shifting the balloon toward the folded configuration. A plurality of elongate flexible electrode assemblies may be disposed on the balloon. The elongate flexible electrode assemblies may be oriented at an angle relative to a longitudinal axis of the balloon.

Renal nerve ablation catheter having twist balloon

A medical device for sympathetic nerve ablation may include a catheter shaft, an expandable member disposed on or coupled to the catheter shaft, and a plurality of elongate electrode assemblies each constructed as a flexible circuit having a plurality of layers. The expandable member may be configured to shift between an unexpanded configuration and an expanded configuration. The plurality of electrode assemblies may be disposed on an outer surface of the expandable member. Each of the plurality of electrode assemblies may include a temperature sensor within the plurality of layers.

Embedded thermocouple in denervation flex circuit

A deflective medical device including a catheter shaft having a distal end, and an ablation electrode disposed at the distal end of the catheter shaft. A deflection body is provided within the catheter shaft, and the deflection body includes a longitudinally extending spine. Multiple slots are formed in the deflection body, and the slots define a group of ribs. A flex member is disposed distal to the deflection body, and an intermediate region is defined between the deflection body and the flex member. A deflection mechanism is coupled to the intermediate region, which includes a retaining member, a collar, and a pull wire coupled to the collar.

Deflectable medical devices

Intravascular device for matching impedances of portions of an intravascular circuit and limiting RF signal-induced heating of intravascular conductors. An intravascular device includes alternating conductive and dielectric layers and an electrically conductive coil in a configuration that effects an impedance-matching circuit. Another embodiment of an intravascular device has cylindrical inner and outer walls formed of an expandable, electrically conductive material, the inner and outer walls being separated by a compressible dielectric material. Varying the pressure in the lumen defined by the inner wall changes the spacing between the inner and outer walls, thereby changing the capacitance between the inner and outer wall. Another embodiment of an intravascular device includes one or more coaxial chokes for limiting heating caused by currents induced by RF signals. A conductive shield of the choke is formed of a conductive polymer to further reduce heating effects. Other embodiments include different transmission lines and antenna structures.
