SUPPORT-FRAME-CENTERED CATHETER FOR CHEMICAL ABLATION

In some examples, a medical system for delivering a chemical agent into a perivasculature of a patient includes a catheter (102) defining a central longitudinal axis; and a neuromodulation assembly at a distal portion of the catheter, wherein the neuromodulation assembly includes one or more fluid-d...

Beschreibung
Zusammenfassung:	In some examples, a medical system for delivering a chemical agent into a perivasculature of a patient includes a catheter (102) defining a central longitudinal axis; and a neuromodulation assembly at a distal portion of the catheter, wherein the neuromodulation assembly includes one or more fluid-delivery needles (120) configured to extend radially outward from the central longitudinal axis at a distal portion of the catheter; and a radially expandable support frame (124) positioned both proximal and distal to the one or more fluid-delivery needles, the radially expandable support frame configured to contact a vessel wall of a vessel (118) of a patient to approximately radially center the distal portion of the catheter within the vessel and to distribute an applied pressure between the neuromodulation assembly and the vessel wall.
