Abstract: 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.

Abstract: A needle includes a hub and an elongate body. The elongate body has a proximal portion joined to the hub and defining a proximal end, a distal portion opposite the proximal portion and defining a distal end, and an intermediate portion between the proximal portion and the distal portion and having a first end adjacent the proximal portion and a second end adjacent the distal portion. A lumen extends longitudinally through the elongate body. The proximal portion extends linearly along a longitudinal axis and has a proximal diameter. The distal portion is curved to space the distal end away from the longitudinal axis and has a distal diameter that is less than the proximal diameter. The intermediate portion tapers in outer diameter going from the first end to the second end.

Abstract: A medical puncture device includes an elongate shaft having a proximal portion defining a proximal end and a distal portion defining a distal end. The distal portion tapers in outer diameter going towards the distal end to define a dilating tip. A lumen extends through the shaft from the proximal end to the distal end. The shaft includes a first electrical conductor that extends from the proximal portion to the distal portion and is electrically connectable to a radiofrequency generator. A radiofrequency puncture electrode is positioned proud of the distal end and is electrically connected to the first electrical conductor.

Abstract: Novel and unique medical devices and associated methods are disclosed, for a medical device for puncturing tissue at a tissue site. The medical device is an elongate member having a proximal section, a distal section, and a rail section therebetween. The medical device includes an active tip at a distal end of the distal section and is operable to deliver energy to create a puncture through the tissue. The rail section is configured to both act as a rail for supporting installation of one or more tubular members thereupon, as well as be maneuverable for enabling access to the tissue site.

Abstract: Novel and unique medical devices and associated methods are disclosed, for facilitating efficient and repeatable puncture of a tissue site while allowing vascular access from various access sites of a patient's body. Disclosed medical devices include dilators and wires usable alone or in combination and configured to facilitate tissue access and puncture at various anatomical locations from desired access sites. The medical devices each include one or more sections having sufficient flexibility for accessing the tissue site from the access site while retaining sufficient stiffness to perform one or more additional functions.
