Systems, devices, and methods for transvascular ablation of target tissue. The devices and methods may, in some examples, be used for splanchnic nerve ablation to increase splanchnic venous blood capacitance to treat at least one of heart failure and hypertension. For example, the devices disclosed herein may be advanced endovascularly to a target vessel in the region of a thoracic splanchnic nerve (TSN), such as a greater splanchnic nerve (GSN) or a TSN nerve root. Also disclosed are methods of treating heart failure, such as HFpEF, by endovascularly ablating a thoracic splanchnic nerve to increase venous capacitance and reduce pulmonary blood pressure.

Methods and devices for endovascular ablation of a splanchnic nerve

A guiding catheter system for delivering an elongated therapeutic or diagnostic device into a patient's left ventricle which includes a first guiding catheter with a shaped distal extremity configured to be aligned with or parallel to a longitudinal axis or long dimension of the patient's left ventricle and a second guiding catheter slidably and rotatably disposed within an inner lumen of the first guiding catheter which has a shaped distal shaft section and an inner lumen configured to slidably receive an elongated therapeutic or diagnostic device such as a tissue ablation device, e.g. an optical fiber connected to a laser source, an ultrasonic energy emitting device or a radio frequency energy emitting device. The shaped distal section of the first guiding catheter is shaped or is shapable within the patient's heart chamber. The second guiding catheter is advanced out of the inner lumen of the first guiding catheter until the distal end extends out of the port in the distal end of the first guiding catheter and provides a passageway for the therapeutic or diagnostic device to engage the endocardium surface at a perpendicular or near perpendicular orientation.

Guiding catheter system for ablating heart tissue

Apparatus and methods for delivering an angiogenic agent to a site within the heart. Either using a percutaneous, intraoperative or minimally invasive approach, an elongated member containing an angiogenic agent is guided to a heart wall and the agent is dispensed into heart tissue. Additional fluids or substances can be dispensed in combination with the angiogenic agent to provide visualization and site mapping. In certain embodiments, the angiogenic agent is delivered adjunctively with the administration of energy, such as laser energy or RF energy which disturbs the heart tissue sufficiently to enhance the effects of the angiogenic agent. A delivery catheter system for delivering a substance delivery member into a patient's left ventricle which includes a first delivery catheter with a shaped distal extremity configured to be aligned with or parallel to a longitudinal axis or long dimension of the patient's left ventricle and a second delivery catheter slidably and rotatably disposed within an inner lumen of the first delivery catheter which has a shaped distal shaft section and an inner lumen configured to slidably receive a substance delivery member such as an elongated cannula slidably disposed within a polymer sheath.

An intracorporeal device generally having an elongate shaft with an asymmetric radiopaque marker disposed upon or within the distal end thereof. The radiopaque marker member enables the user to determine the orientation of the distal end of the device under fluoroscopic and similar imaging techniques. In certain embodiments the device is configured as a delivery catheter system having multiple delivery catheters, some or all of which may have radiopaque marker members disposed upon or within their distal ends. The delivery catheter system is configured in some embodiments to deliver an elongated diagnostic or therapeutic device to a desired location within a patient's heart.
