摘要： 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.

摘要： A medical electrical lead (10) including an inflatable member (12) at a distal tip section, and a system of use, are disclosed. The inflation member is adapted to engage the walls of a cardiac vein or coronary artery to occlude the vessel. According to one aspect of the invention, the inflation member is formed of a bio-absorbable material. In another embodiment, the inflation member is a micro-porous material. The lead of the current invention may include a port located distal to the inflation member is in the inflated state. This allows a fluoroscopic image of a patient's vascular system to be obtained while the lead is in place within a vessel. A perfusion lumen may be provided to allow a partial flow of blood to continue around the inflation member (18) when the inflation member is occluding a vessel. In one embodiment, lead is provided with a lumen for receiving a stiffening menber such as a stylet (64) to aid in lead is placement. According to one method of using the current invention, inflation member may be inflated after the lead is placed at a desired implant site to provide a temporary fixation mechanism during withdrawal of the stiffening member and/or a guide catheter or sheath used to place the lead at the implant site. This temporary fixation mechanism may also be employed to retain a desired lead location while thresholds are obtains. The inflation member may be retained in an inflated state for a longer predetermined period of time until tissue in-growth begins to occur around the lead.

摘要： An introducer catheter used to deliver an endocardial cardiac electrode has a stylet lumen which collapses upon removal of the stylet to allow for more clearance for the lead and connector to pass when the catheter is removed after lead placement. The collapsible stylet lumen permits the introducer catheter size to be reduced to 8 or 9 French and provide for passage of a 4 French lead.

摘要： A distal tip coupled to a body of an implantable medical device includes a canted passageway extending distally from a lumen of the body and an opening terminating the passageway and positioned in proximity to a distal end of the distal tip; a helical fixation element coupled to an elongated member extending within the lumen of the body is adapted to deflect along the canted passageway of the distal tip. The elongated member is adapted to move the helical member through the passageway of the distal tip and out from the opening and to rotate the helical element thereby affixing the helical element into an implant site.

摘要： The present invention provides a practical, multi-polar, in-line connector system for use in connecting implantable medical devices (IMD) and associated non-standard, low profile medical electrical leads. In addition, the present invention provides a system that uses tool less, frictional, sealed, compressive electrical connections for most or all of the electrical interconnections between an IMD and a low profile lead. A protective sleeve seals the lead connector to the non-standard port to prevent intrusion of body fluids therein. In addition, optional microchip-based circuitry coupled to the sleeve enables wireless communication and remote programming for diverse IMDs. Memory associated with the circuitry can store, update and reprogram a wide variety of information relevant to the IMD, the patient, and the attending physician, among others. For example, the microchip may be used to identify the lead type and characteristics, as well as other useful data.

摘要： An implantable medical electrical lead includes a plurality of conductors that extend continuously, without any intermediary junctions, between a plurality of electrodes and a corresponding plurality of contact members of an in-line connector terminal. A junction between each conductor and the corresponding contact member is preferably formed by first fitting a conductive sleeve, which is coupled to a proximal portion of the conductor, into an eyelet feature of the contact member, which is mounted on a strut member, and then welding the sleeve to the contact member at a pre-formed slot of the contact member, which extends along an external recessed surface thereof. The assembly of the connector terminal preferably completes the construction of the lead, wherein the proximal portion of each conductor is positioned in a helical path, which extends between an elongate body of the lead and the connector terminal, and along which a grip zone is formed.
