    摘要： An apparatus for subcutaneous lead guidance includes a flexible guide strap (130), a navigation catheter (150) and a tunneling tool (110). The guide strap includes an upper layer (134) having a plurality of retainer formations (136) and a substrate (132) attachable on a patient's skin extending between an incision (80) and a target site (84). The navigation catheter is coupled to the upper layer via the retainer formations from a first end (130a) to a second end (130b) of the guide strap. The navigation catheter includes a plurality of position sensors (140) for generating a subcutaneous navigation volume (170) between the incision and the target site when the navigation catheter is coupled to a navigation system (10). The tunneling tool has a distal portion (116) with a leading end (112) and at least one position sensor on the distal portion for viewing digital representation of the distal portion in relation to the navigation volume on a display (36) coupled to the navigation system.

    摘要： A stylet for an image guided system, which includes a locating device and which is operable for emitting an electromagnetic field for locating the stylet. The stylet includes a flexible elongate member, an electrically conductive member, and a reinforcement member. The reinforcement member is disposed inside the electrically conductive member and is made out of a magnetic material. The reinforcement member reinforces the stylet and provides electrical communication between the conductive member and the locating device such that current induced in the conductive member is transmitted to the locating device via the reinforcement member.

    摘要： A medical instrument assembly is disclosed. The medical instrument has proximal and distal ends. A receiver coil being mounted proximate to a distal end of the medical instrument, the receiver coil being electrically connectable at a proximal end of the medical instrument. A deployable object being disposed and movable within the medical instrument. The deployable object bearing a high magnetic permeability material located proximate to the receiver coil. The high magnetic permeability material and the receiver coil combining to form an inductive element having an inductance that varies in a predetermined manner with the position of the deployable device relative to the receiver coil. A determination of the inductance being performed at the proximal end of the delivery catheter indicates the extension of the deployable device through the medical instrument.
