  • Patent number: 7287995
    Abstract: A lead connector arrangement includes a non-cylindrically shaped connector pin coupled to a lead conductor and a connector sleeve assembly for receiving the non-cylindrically shaped connector pin. The connector sleeve assembly includes an insert with an axial bore formed therein that complements the shape of the non-cylindrical connector pin. According to one embodiment, the non-cylindrical connector pin may be provided in the form of a triangular, square, rectangular, or hexagonal shape. The axial bore has a complimentary shape to receive the connector pin. When the connector pin is threaded through the connector sleeve assembly using a pull-wire device, the pull-wire device may be unscrewed from the connector pin without causing axial rotation of the lead conductor when the connector pin is fully inserted within the axial bore.

  • Patent number: 7254450
    Abstract: The invention is directed to lead configurations for sensors that allow for less invasive sensor replacement procedures. In one configuration, a sensor lead assembly includes an outer lead body and an inner lead including a sensor such as an electrochemical glucose sensor. The inner lead can be positioned in an inner conduit of the outer lead body. The outer lead body may be substantially permanently implanted in the patient, and the inner lead can be implanted through the inner conduit of the outer lead body. Once the sensor of the inner lead has worn out or otherwise exhausted its useful life, the inner lead can be removed, and a new inner lead can be implanted in place of the old inner lead.

  • Patent number: 7239916
    Abstract: An automated identification and configuration system for use with an implantable medical device (IMD) is disclosed. The system includes a first communication circuit that is attached to, or otherwise carried by, a detachable component associated with the IMD such as a medical lead. The communication circuit stores data such as model numbers, serial numbers, technical data, and/or calibration information that describes the additional component. This information may be transferred by the first communications circuit to a second communications circuit that is external to the additional component. This transferred data can be used to automatically configure the internal circuitry and connection functions of the IMD to properly interface with, and support, the additional component. For example, the data can be used to automatically adjust amplifier gains or other sensor circuitry, or to configure a connector block to properly couple to the component.

  • Patent number: 7107105
    Abstract: An improved medical lead assembly and method of use is provided. The lead assembly includes a lead body, and a spring member positioned adjacent to the lead body. The spring member may be deployed a selectable amount to maintain the lead body in a fixed location within a patient's body. The spring member may be an expandable coil, a mesh structure that is similar to a stent, or any other similar device that may be positioned in a low-profile state during a lead implant procedure. After the lead is positioned at a target destination, the spring member may be deployed an amount that is selected based on the characteristics of the surrounding tissue, including vessel size. According to one aspect of the invention, the lead assembly may provide means for facilitating chronic lead extraction.
