A method and apparatus are disclosed for providing forward fluid delivery through an electrosurgical device, while avoiding coring when energy is delivered to the electrosurgical device. The device has a distal face defining an opening, with the distal face including at least one cutting portion and at least one non-cutting portion. An embodiment of the electrosurgical device for puncturing tissue includes an elongate member defining a lumen for fluid; a distal portion including an electrode and the distal face which defines at least one aperture. The portion of the at least one cutting portion defines a leading portion partially surrounding a circumference of the at least one aperture wherein the outer diameter of the at least one of the distal portion of the electrosurgical device or the electrode decreases towards a distal tip of the electrosurgical device.

Electrosurgical device having a distal aperture

A releasable coupling mechanism for coupling a delivery catheter and a dilator. The delivery catheter comprising a delivery catheter hub at the proximal end and the dilator comprising a dilator hub at the proximal end. The proximal end of the delivery catheter hub comprises a coupling member for releasably receiving a raised portion which is positioned at a distal end of the dilator hub. The coupling member has a pair of engagement members positioned on opposing sides of the coupling member and configured to releasably engage the raised portion. The delivery catheter hub further comprising at least one indicia on the housing. The indicia indicate an orientation of the delivery catheter hub such that the dilator hub disengages from the coupling member by simultaneously deflecting the pair of engagement members.

A method and apparatus are disclosed for providing forward fluid delivery through an electrosurgical device, while avoiding coring when energy is delivered to the electrosurgical device. The device has a distal face defining an opening, with the distal face including at least one cutting portion and at least one non-cutting portion. An embodiment of the electrosurgical device for puncturing tissue includes an elongate member defining a lumen for receiving a fluid; a distal face defining at least one aperture; and the distal face including at least one cutting portion and at least one non-cutting portion cooperating to produce an elongated cut in a tissue when electrical energy is delivered to the distal face while avoiding coring of the tissue.

A method and apparatus are disclosed for a catheter having a side-port through which a wire may be advanced. The catheter comprises a catheter body, the catheter body defining at least a primary catheter lumen and at least one side-port in communication with the primary catheter lumen, and a distal portion of the catheter extending distal to the at least one side-port, the side-port being configured to allow travel of a wire or other component therethrough, wherein the distal portion of the catheter is radially collapsible.
