摘要： An improved system for monitoring the status of an IMD such as a medical electrical lead during an implant procedure is provided. The system includes a signal generator for supplying a first signal such as a constant current or voltage to the IMD. A resulting voltage or current signal is generated, respectively, and may be sensed as an indication of the impedance of a portion of the body that is proximal to one or more electrodes carried by the lead. This impedance indication is converted to an audible signal having a frequency that is proportional to the amplitude of the impedance indication. The pitch of the audible signal therefore rises when measured impedance increases, and drops as the impedance decreases. These pitch changes allow a user to determine positional information associated with the IMD, including the degree of lead tissue contact and extent of fixation of a device to tissue.

摘要： A method and apparatus for accessing the pericardial space which provides for stable short term or long term placement of a delivery catheter or cannula having its distal most end located in the pericardial space. The catheter or cannula may be introduced into the pericardial space either transvenously through the wall of a heart chamber or transthoracically by penetrating the chest wall and the pericardium. Some embodiments are provided with a mechanism for stabilizing the distal end of the catheter or cannula, which mechanism may employ an extensible elastic, generally tubular member located at the distal end of the catheter or cannula. The device may be provided with a mechanism for extending the tubular member longitudinally, causing its diameter to diminish substantially. The tubular member may be passed through the wall of the heart or the pericardium in its extended configuration and thereafter, the distal-most portion of the tubular member may be moved proximally, causing its diameter enlarge, anchoring the distal end of the catheter or cannula to the pericardium or to the wall of a heart chamber. In these embodiments, the device is preferably provided with a shoulder or flange located proximal to the extendible tubular member, for location on the opposite side of the heart wall or pericardium from the distal end of the catheter or cannula.

摘要： An introducer or guide catheter for directing an implantable medical device such as a lead or catheter to a desired location within a patient's body. In one embodiment of the invention, the introducer comprises a two-lumen tube. A first lumen is configured to receive the implantable medical device that is to be introduced. A second lumen is provided to receive an insertable, elongated guiding member such as a stylet, which may be shapable in various orientations, and which may be used to alter the configuration of the introducer. The second lumen may be provided with an internal coil or other tubular reinforcement member to prevent perforation of this lumen by the guiding member when the introducer is in the patient's body. In order to facilitate removal of the introducer over an implantable medical device having a connector or fitting that is larger than the internal diameter of the first lumen, the introducer may be adapted to be slit or split along its length. In some embodiments of the invention, the introducer may be rendered splittable by provision of a weakened zone along its length. According to yet another aspect of the invention, the introducer may be provided with a luer lock at its proximal end to facilitate connection of the introducer to a hemostasis valve, t-fitting, or the like.

摘要： An introducer of the type employing an elongated introducer sleeve for receiving a catheter or lead body and an associated hemostasis clamp including a clamping member configured to engage the outer circumference of the introducer sleeve. The clamp is provided with a mechanism for maintaining the clamping member in engagement with said outer circumference of the sleeve to compress the outer circumference of the sleeve around a catheter or lead body inserted therethrough. In some embodiments the clamp takes the form of a hinged clamp provided with two jaws each having a recess adapted to engage a portion of the other circumference of the introducer sleeve. In other embodiments the clamp takes the form of interacting ramped members. The clamp is maintained in engagement with the sleeve either resiliently or by means of a latch.
