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： An implantable medical device (IMD) can include a cardiac pacemaker or an implantable cardiac defibrillator (ICD). Various portions of the IMD, such as a case or device body, the lead body, or the lead tip, can be provided to reduce or dissipate a heat production due to a current induced by various external environmental factors. According to various embodiments, features or portions can be incorporated into the lead body, the lead tip, or the IMD body to reduce the creation of an induced current, or dissipate or increase the area of dissipation of thermal energy created due to an induced current in the lead.

摘要： The invention is directed to medical lead designs that facilitate implantation of the leads through tissue. For example, the leads can implanted though tissue for placement of distal tips of the leads in locations on the opposing side of the tissue. The leads include fixation elements, such as flexible tines, that facilitate fixation to the tissue. The fixation elements can protrude from lead at a location more than 5 millimeters from the distal-tip of the lead such that when the distal tip has passed through the tissue, the fixation elements anchor in the tissue.

摘要： A transvenous implantable medical device adapted for implantation in a body, and which is particularly adapted for use in a vessel such as the coronary sinus or cardiac great vein. The implantable medical device may take the form of a lead or catheter, and includes an extendable distal fixation member such as a helix. In one embodiment, the fixation member is a helix constructed of a shape memory metal or other super-elastic material. Upon deployment, the helix assumes a predetermined helix shape larger than the diameter of the lead body diameter. The helix functions to wedge or fix the lead within the vessel in a manner that does not impede the flow of blood through the vessel. The helix may be retracted for ease of repositioning and/or removal. In one embodiment of the invention, the fixation member may be advanced using a stiffening member such as a stylet. In another embodiment, the helix is coupled to a coiled conductor such that rotation of the conductor extends or retracts the helix. According to yet another aspect of the invention, a helix lumen including a flexible fluid-tight seal may be utilized to house the helix when it is in the retracted position.

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.
