  • Patent number: 11253166
    Abstract: This invention relates to a method of catheter and radiating coil location in a human body. In particular, when a radiating coil is used in conjunction with a catheter, a coil locating device can be used to determine the distance the coil is from the device and its depth in the patient's body. A display is provided that shows both a reference image of a portion of a non-subject body and an image of the coil located on the display with reference to the reference image. This is achieved by locating the coil-locating device on a predetermined landmark on the patient's body. The coil and its signal wires can be incorporated into a stylet, guide wire or a catheter. The coil locating device can be orientated towards the head of the patient and for an axis of the device to be aligned with the mid sagittal plane of the patient.

  • Patent number: 10940312
    Abstract: The exemplified systems and methods facilitate a nerve conduction block at a target nerve using electrical stimulation applied from one or more electrodes located on a percutaneous lead that are placed in parallel, or substantially in parallel, and without direct contact, to a long axis of the peripheral nerve over an overlapping nerve region of greater than about 3 millimeters. The exemplified system and method can be further configured to block nerve condition without eliciting onset activity and co-excitation of non-targeted structures. The exemplified method and system can be performed using conventional percutaneous leads, though an improved percutaneous lead design is disclosed herein. In an aspect, an introducer is disclosed that facilitates accurate and consistent insertion of the percutaneous lead to the specified or intended position relative to the target nerve. In another aspect, a treatment kit comprising the various system components to treat pain is disclosed.
