20110071540 | LEAD WITH DISTAL ENGAGEMENT FEATURE TO FACILITATE LEAD PLACEMENT - An implantable medical lead includes a proximal portion including a contact. The lead also includes a distal portion having a paddle-shaped portion, an electrode, and an engagement element configured to cooperate with a lead advancement tool to facilitate placement of the lead such that distal advancement of the tool relative to the lead pushes the lead distally. The electrode is electrically coupled to the contact, and the engagement element is distal to the electrode. The engagement element is integrally formed with the paddle-shaped portion. | 03-24-2011 |
20110071606 | BIFURCATED LEAD SYSTEM AND APPARATUS - Bifurcated leads may simplify implantation procedures associated with electrical single therapy at two distinct anatomical locations, such as a left and a right occipital nerve. | 03-24-2011 |
20110082516 | LEAD HAVING RADIALLY SPACED APART CONTACTS TO ALLOW FOR ADJUSTABILITY - An implantable medical lead includes a lead body having a proximal portion and a distal portion. The lead also includes first and second contacts located at the proximal portion of the lead body, and includes first and second electrodes located at the distal portion of the lead body. The first electrode is electrically coupled to the first contact and the second electrode is electrically coupled to the second contact. The first contact has a proximal end and a distal end and the second contact has proximal end and a distal end. The second contact is radially spaced apart from the first contact. The contacts do not extend around the lead body. This disclosure also relates to an implantable lead extension and to an implatable signal generator having connectors configured to receive the present lead. | 04-07-2011 |
20110087305 | MEDICAL LEAD SYSTEM WITH ROUTER - A medical electrical lead system includes an electrical signal generator providing a plurality of discrete electrical signal channels and an electrical signal channel router electrically coupled between the electrical signal generator and a first lead body and a second lead body. The electrical signal channel router diverts one of the discrete electrical signal channels to the second lead body and not to the first lead body. | 04-14-2011 |
20110093034 | BIFURCATED LEAD WITH INTEGRATED ANCHOR AT BRANCH REGION - An implantable medical lead includes a proximal portion having first and second contacts. The lead further includes a first distal arm having a first electrode that is electrically coupled to the first contact, and includes a second distal arm having a second electrode that is electrically coupled to the second contact. The lead also includes a branch region where the proximal portion transitions to the first and second distal arms. A tissue anchoring element is attached to the branch region for securing the branch region to tissue of a patient into which the lead is implanted. Such bifurcated leads may be used to apply electrical signals to occipital nerves of the patient via the electrodes. A lead extension includes a distal connector with two lead receptacles and a tissue anchoring element attached to the connector. An adaptor having three lead receptacles includes an anchoring element attached thereto. | 04-21-2011 |
20110257717 | IMPLANTABLE MEDICAL LEAD - An implantable medical lead includes a lead body, a first electrode, a second electrode, a third electrode, and a fourth electrode. The electrodes are located at fixed positions along the length of the lead body, and the second and third electrodes are positioned between the first and fourth electrodes. The first electrode has a proximal end, the fourth electrode has a distal end, and the distance from the proximal end of the first electrode to the distal end of the fourth electrode is between 5 centimeters and 7 centimeters. The combined length of the second and third electrodes is between 2.5 and 5 times greater than the combined length of the first and fourth electrodes. The lead may be used for applying electrical signals to an occipital nerve of a patient. | 10-20-2011 |
20120038477 | DETECTION OF PROPER INSERTION OF MEDICAL LEADS INTO A MEDICAL DEVICE - Proper insertion of medical leads into medical devices is detected at the time the lead is being inserted. An external device initiates impedance testing by the medical device that is receiving the lead prior to the insertion of the lead being completed. The medical device reports back the results of the impedance testing so that the external device can determine whether the lead is properly inserted at the time of lead insertion and can provide an output to a user to indicate whether the lead insertion is proper. The medical device may poll only a last connector expected to be connected before responding, test other connector combinations before or after responding, and so forth. | 02-16-2012 |
20140200642 | LEAD HAVING RADIALLY SPACED APART CONTACTS TO ALLOW FOR ADJUSTABILITY - An implantable medical lead includes a lead body having a proximal portion and a distal portion. The lead also includes first and second contacts located at the proximal portion of the lead body, and includes first and second electrodes located at the distal portion of the lead body. The first electrode is electrically coupled to the first contact and the second electrode is electrically coupled to the second contact. The first contact has a proximal end and a distal end and the second contact has proximal end and a distal end. The second contact is radially spaced apart from the first contact. The contacts do not extend around the lead body. This disclosure also relates to an implantable lead extension and to an implantable signal generator having connectors configured to receive the present lead. | 07-17-2014 |
