摘要: A medical probe device of this invention comprising a catheter having a control end and a probe end. The probe end includes a stylet guide housing having at least one stylet port and stylet guide means for directing a flexible stylet outward through at least one stylet port and through intervening tissue to targeted tissues. A stylet is positioned in at least one of said stylet guide means, the stylet comprising a non-conductive sleeve having a RF electrode lumen and an optional a fluid supply lumen and a temperature sensor lumen therein. At least one portion of an opposed surface of the electrode lumen and the electrode can be spaced apart to define a liquid supply passageway for delivery of medicament liquid. The RF electrode enclosed within the non-conductive sleeve has a distal length optionally having at least one current focusing groove means thereon and a distal tip shaped to focus current crowding on its terminal end, whereby Rf current passing therefrom into surrounding tissue forms a lesion extending outward from the groove and tip. The focusing groove means can be a plurality of annular focusing grooves or a spiral focusing groove thereon.

摘要: An electrosurgical device comprising an elongate probe member having proximal and distal extremities and a passage extending from the proximal extremity to an opening at the distal extremity. The elongate probe member is provided with an elongate cutout adjacent the opening so that the elongate probe member is formed with an elongate extension projecting alongside the cutout beyond the opening. A guide canula is mounted in the passage of the elongate probe member and has proximal and distal extremities and a lumen extending therethrough. A radio frequency electrode is disposed in the lumen and an insulating sleeve is coaxially disposed on the radio frequency electrode. A handle is secured to the proximal extremity of the guide canula for advancing and retracting the radio frequency electrode and the insulating sleeve with respect to the guide canula and for causing bending of the distal extremity of the guide cannula into the cutout. The extension of the elongate probe member provides support to the guide cannula against the force of the radio frequency electrode engaging the tissue. A method for using the device is provided.

摘要: An electrosurgical device for medical treatment of tissue at a treatment site through a body opening. The device includes a sheath having proximal and distal extremities and having a passageway extending from the proximal extremity to the distal extremity. A guide tube is slidably mounted in the passageway of the sheath and has proximal and distal extremities and a lumen extending from the proximal extremity to the distal extremity. A needle electrode is slidably mounted in the lumen of the guide tube and has proximal and distal extremities. Insulation is coaxially disposed on the needle electrode. A handle adapted to be gripped by the human hand is provided and the proximal extremity of the guide tube is mounted on the handle. An assembly is carried by the handle for bending the distal extremity of the guide tube at an angle with respect to the longitudinal axis. The needle electrode is adapted to be coupled to an energy source. A single actuation element is carried by the handle and coupled to the needle electrode and the insulation. The actuation element is movable in a single stroke from a first position in which the needle electrode and the insulation are disposed within the guide tube and a second position in which the needle electrode and the insulation are disposed in the tissue at the treatment site. A method for using the device is provided.

摘要: A medical probe device of this invention comprising a catheter having a control end and a probe end. The probe end includes a stylet guide housing having at least one stylet port and stylet guide means for directing a flexible stylet outward through at least one stylet port and through intervening tissue to targeted tissues. A stylet is positioned in at least one of said stylet guide means, the stylet comprising a non-conductive sleeve having a RF electrode lumen and an optional a fluid supply lumen and a temperature sensor lumen therein. At least one portion of an opposed surface of the electrode lumen and the electrode can be spaced apart to define a liquid supply passageway for delivery of medicament liquid. The RF electrode enclosed within the non-conductive sleeve has a distal length optionally having at least one current focusing groove means thereon and a distal tip shaped to focus current crowding on its terminal end, whereby Rf current passing therefrom into surrounding tissue forms a lesion extending outward from the groove and tip. The focusing groove means can be a plurality of annular focusing grooves or a spiral focusing groove thereon.

摘要: A medical probe device comprising a catheter having a stylet guide housing with at least one stylet port in a side thereof and stylet guide means for directing a flexible stylet outward through at least one stylet port and through intervening tissue to targeted tissues. The stylet guide housing has an optical viewing means positioned for viewing the stylet and adjacent structure which includes a fiber optic channel means for receiving a fiber optic viewing device. The fiber optic channel means can include a guide port means for directing longitudinal movement of a fiber optic device with respect to the stylet guide means in a viewing zone and a flushing liquid channel in the stylet guide housing having an exit port positioned to direct flushing liquid issuing therefrom across the end of a fiber optic device when positioned in the viewing zone. The optical viewing means can comprise a viewing window positioned in the stylet guide housing for viewing the stylet when it is directed outward from its respective stylet port. The optical viewing means can include a fiber optic channel in the stylet guide housing for receiving the a fiber optic viewing device and aligning the viewing end thereof with the viewing window. Windowed devices can include a flushing liquid channel in the stylet guide housing having an exit port positioned to direct flushing liquid issuing therefrom across a surface of the viewing window.
