20100268311 | Method for Implanting Electrode on Nerve - Methods and devices for implanting an electrode near a nerve covered by a tissue layer or layers. Methods can include cutting through a tissue layer covering the nerve to form at least two exposed pleural tissue layer edges. The nerve can be freed from any tissue around the nerve and the electrode placed around the nerve. The pleura edges can be drawn toward each other to cover the nerve and the edges secured together. Some methods form two tissue flaps which are pulled away from each other to expose the nerve. Other methods form a single tissue flap which extends over the nerve and is pulled back to expose the nerve. The now covered nerve is protected against movement of tissues near the now covered nerve. Such methods find one use in placing electrodes near the splanchnic nerves in the thoracic cavity, where the lung and diaphragm may contact an exposed electrode. | 10-21-2010 |

In use, the tube body can be pulled apart using attached suture loops, with one loop and flap pulled under the nerve followed by part of the tubular body. The tubular body can be closed over the nerve and the flap closed over the tube slit. | 08-02-2012 |

20080262587 | EXTENDABLE AND RETRACTABLE LEAD HAVING A SNAP-FIT TERMINAL CONNECTOR - A lead having an extendable and retractable fixation mechanism has a rotating terminal pin at the terminal end which rotates the fixation mechanism at the distal end. As the terminal pin is rotated, the fixation mechanism is extended or retracted from the distal end of the lead. A threaded collar allows for the fixation mechanism to smoothly extend and retract from the lead, and allows for a 1:1 turn ratio between the terminal pin and the fixation mechanism. A fluoroscopic ring disposed at the distal end of the lead provides information during the implantation process. | 10-23-2008 |

20080249596 | MYOCARDIAL LEAD WITH FIXATION MECHANISM - The present invention is a myocardial lead attachment system for securing a distal end of a cardiac lead within a myocardium of a patient's heart and anchoring against an epicardium of the patient's heart. The system includes an anchor configured to advance in a first orientation and anchor against an epicardial surface in a second orientation and a tether having a proximal end and a distal end. The anchor is coupled to the distal end of the tether. The system includes a cardiac lead having a lead body, a lumen extending through the lead body, a conductive member, a proximal end, a distal end, and an electrode configured for stimulating the myocardium located at the distal end. The lead body and the lumen are configured such that the lead body can be threaded over the proximal end of the tether and slideably advanced over the tether toward the anchor during implantation. The system includes a fixation mechanism at the distal end of the cardiac lead. The fixation mechanism is adapted to collapse to a first configuration during implantation and deploy to a second configuration after implantation. | 10-09-2008 |
