Tissue-penetrating guidewires with shaped tips, and associated systems and methods are disclosed. A patient treatment system in accordance with one embodiment of the disclosure includes a tissue-penetrating guidewire that in turn includes a flexible segment having a distal portion and a proximal portion. The flexible segment is elongated along an elongation axis. A penetrating member is positioned at the distal portion and includes at least one blade segment having a tapered outer peripheral surface and an adjacent generally sharp edge. The blade segment extends to a distal end of the penetrating member to form a generally blunt tip. In operation, the guidewire can be connected to an electrical current source to deliver high frequency current to the penetrating member.

Tissue-penetrating guidewires with shaped tips, and associated systems and methods

Systems and methods for transeptal cardiac procedures are disclosed. A method for treating a patient in accordance with a particular embodiment includes positioning a tissue penetrating guidewire adjacent to a cardiac septum, directing pulses of energy to the guidewire, and advancing the guidewire into and through the septum by moving the guidewire in a distal direction in a series of discrete steps. Individual steps can be of a predetermined distance measured outside the patient's body. The method can further include passing a catheter over the guidewire after the guidewire has passed through the septum.
