Abstract: An electrosurgical device for puncturing tissue comprises an electrically conductive elongate member which is capable of force transmission from a distal portion of the electrosurgical device to a proximal portion of the electrosurgical device to thereby provide tactile feedback to a user. The proximal portion comprises a connector system for connecting a source of energy and a source of fluid to an electrosurgical device. The connector system includes a hub which includes an electrically conductive lengthwise member having a lengthwise member distal region and a lengthwise member proximal region. The lengthwise member defines a hub lumen therebetween and is configured to be operatively coupled to an electrosurgical device.

IPC: A61B18/14

Abstract: A method and apparatus are disclosed for providing forward fluid delivery through an energy delivery device that avoids coring when it delivers energy to a tissue. The device has a distal face defining an opening, with the distal face including at least one electrically exposed portion and at least one electrically insulated portion. An embodiment of the energy delivery device includes an elongate member defining a lumen structured to receive a fluid, and a distal face defining an aperture in communication with the lumen. The distal face includes an electrically exposed conductive portion and an electrically insulated portion. The electrically exposed conductive portion is configured such that the energy it delivers while the energy delivery device is advanced into a tissue punctures the tissue without the tissue substantially occluding the lumen and without creating embolic particles.

Abstract: This disclosure describes embodiments of a kit and its constituent components which together form an apparatus in which fluid communication between a medical device's lumen and the surrounding environment is provided by a conduit cooperatively defined by the medical device and a tubular member into which the device is inserted. The medical device and tubular member are configured to fit together such that an outer surface of the distal region of the medical device cooperates with an inner surface of the tubular member to define the conduit between the side-port of the medical device and a distal end of the tubular member. The conduit is operable to be used for injecting fluid, withdrawing fluid, and measuring pressure, for example. Methods of assembling and using the apparatus are described as well.
