摘要： An extendable medical lead comprises a lead body and a sheath defining a cavity that encloses a length of the lead body. The length of the lead body enclosed within the sheath may be coiled or otherwise gathered such that when extended, the length of the enclosed section of the lead body is greater than the length of the sheath. The sheath may include a seal to help prevent contaminant entry into the cavity in order to help reduce tissue in growth around the length of the lead body disposed within the sheath. A portion of the length of the lead body enclosed within the sheath exits the cavity through an aperture defined by the seal when a tensile force is applied to the lead body.

摘要： A medical electrical lead, having an elongated lead body which includes an elongated insulative sheath having proximal and distal ends and which carries spaced first and second electrical components. The first and second electrical components are mechanically and electrically coupled to one another by a coil/fiber assembly extending within the insulative sheath. The coil/core assembly is made of lengths of fiber cord twisted around one another, with a metal coiled conductor wound around the lengths of twisted fiber cord. The coil/core assembly may include two lengths of a single fiber cord, folded back upon itself to define a loop at one end thereof. The first electrical component may be provided with a longitudinal lumen extending therethrough and the fiber core may be tied into a knot located within the lumen of the first electrical component and the coil wound around the first electrical component. The second electrical component may be provided with a hook-shaped member hooked into the loop at the end of the fiber core.

摘要： An electrical connector has a compressible portion that expands to accept an inserted lead and then contracts around the lead to provide both an electrical and a spring-like mechanical connection to the lead. The connector may have a fluted pin that collapses around the lead body when a set screw of the connector port is tightened. Alternatively, a middle segment of a pin may have indentations or slots that collapse around an inserted lead body. The connector can be attached to the lead body after the lead body is implanted in the body of the patient. In lead systems in which the lead body is implanted using a guide catheter, attaching the connector to the lead body after implantation makes removal of the guide catheter much less difficult.

摘要： An atrial lead system providing single electrode bi-atrial pacing. The system includes an atrial pacing lead having electrode (12) located on a distal portion thereof and a guide catheter having a longitudinal lumen and a lateral aperture (104) open to the longitudinal lumen of the catheter proximal to a distal end of the catheter through which the distal portion of the lead may be advanced. The electrode is preferably an active fixation electrode device. First the guide catheter is advanced to the ostium of a patient's coronary sinus and the distal end of the guide catheter is inserted into the coronary sinus such that the lateral aperture (104) of the catheter is located in the patient's right atrium. The atrial pacing lead is then advanced through the lumen of the guide catheter such that the electrode exits the lateral aperture of the guide catheter and the electrode is affixed to the tissue of the atrial septum.

摘要： A cardioversion or defibrillation system including a cardioverter or defibrillator and a lead. The lead carries a single cardioversion/defibrillation electrode formed of one small diameter metal filament for location in a heart chamber and may include a pace/sense electrode. The small diameter defibrillation electrode extends distally from the distal end of the lead body and may have the length of its extension adjusted by means of a movable sheath.

摘要： L'invention concerne un système de fil d'amenée implantable à dispositif de fixation actif qui relie une source d'énergie électrique, telle qu'un stimulateur cardiaque, au tissu cardiaque. Le système de fil d'amenée comprend un fil, un élément d'introduction et un cathéter de guidage. Le fil a un corps de petit diamètre et un dispositif de fixation actif pénétrant dans le tissu cardiaque. Le corps du fil se présente globalement sous une forme droite, déroulée, et a un diamètre extérieur d'environ 0,013 pouce. Le corps du fil comporte une pluralité de fibres conductrices de courant, infinitésimales, bio-compatibles, et biologiquement stables qui sont disposées, de manière serrée, en faisceau afin de former un conducteur simple analogue à un cable. Un revêtement isolant bio-compatible, diélectrique entoure le conducteur de façon à former une couche isolante entre le conducteur et l'environnement du corps du fil. Le dispositif de fixation comprend une partie coulissante qui s'engage dans l'élément d'introduction. Cet élément d'introduction est assemblé au fil et comprend un dispositif d'accouplement s'engageant dans la partie coulissante du dispositif de fixation du fil. Le dispositif d'accouplement comporte un enroulement serré, et un élément engage un embout allongé, généralement cylindrique pourvu d'une ouverture qui agit comme une voie d'accès sur le dispositif de fixation actif. L'élément d'accouplement retient et s'engage fermement dans la partie coulissante du fil d'amenée, et contrôle son engagement et son désengagement dans et hors du tissu cardiaque. D'autre part, cet élément d'accouplement empêche le dispositif de fixation actif de perforer le tissu cardiaque. Un cathéter est monté sur le fil d'amenée et sur l'élément d'introduction afin d'assurer une rigidité et d'améliorer la maniabilité du fil.

摘要： An implantable lead for a medical device includes a lead body having a proximal end and a distal end, an electrical connector coupled to the proximal end of the lead body, an electrode coupled to the distal end of the lead body, and electrically conductive conductor coil extending between the proximal and the distal end of the lead body, the conductor coil wound in a first winding direction under tension. The lead body also includes a plastic ribbon wound around the conductor coil in a second winding direction opposite to the first winding direction without releasing the tension of the conductor coil.

摘要： An electrical stimulation apparatus is provided for delivering an electrical field or electrical current over a predetermined period of time to a vascular tissue in order to stimulate a cell initiated thrombolytic peptide response in cells within the vascular tissue. The electrical stimulation apparatus includes an electrical field or electrical current generating unit including a power supply, a control mechanism interconnected with the power supply, and a plurality of electrodes designed to generate an electrical field or electrical current proximal to, or within to the vascular tissue. The amplitude of the electrical field or electrical current delivered to or generated proximal to, or within the vascular tissue, and the duration of the period of delivery are sufficient to stimulate production of thrombolytic peptides in the vascular tissue. The control mechanism preferably includes a computer processing unit in electronic communication with the power supply, the computer being programmed to cause the electrical stimulation apparatus to deliver a predetermined amount of electricalcurrent or voltage over a predetermined period of delivery to the plurality of electrodes such that the plurality of electrodes are in contact or proximity with the vascular tissue.
