A radiofrequency perforation apparatus for creating a channel at a target location in a body of a patient, the radiofrequency perforation apparatus being usable by an intended user having a hand, the radiofrequency perforation apparatus comprising: a handle graspable by the hand a distal portion, the distal portion defining a distal portion length, the distal portion including an electrode and an electrical insulator extending from the electrode and a force transmitting portion extending between the distal portion and the handle, the force transmitting portion defining a force transmitting portion length, the force transmitting portion length being larger than the distal portion length, the force transmitting portion having a force transmitting portion flexural rigidity of at least about 0.016 Nm2 whereby the force transmitting portion has a force transmitting portion flexural rigidity allowing the transmission to the handle of contact forces exerted on the distal portion when the distal portion contacts the target location to provide tactile feedback to the intended user.
