An implantable medical device (IMD) comprises a plurality of deep tines configured to be advanced into a septum of a heart of a patient in different directions that are not parallel to a longitudinal axis of the implantable medical device, wherein each deep tine of the plurality of deep tines is configured to deliver cardiac pacing to cardiac tissue distal to a chamber of the heart in which the IMD is implanted, and one or more shallow electrodes engageable with the septum, wherein the one or more shallow electrodes are configured to deliver cardiac pacing to the chamber of the heart in which the IMD is implanted.

Multi-electrode implantable medical device (IMD)

Implantable apparatus includes two or more alignable marker elements, and systems and methods for manufacturing such implantable apparatus, and methods to utilize such implantable apparatus. For example, the implantable apparatus may include a first alignable marker element and a second alignable marker element that may be used to ensure proper alignment with a target site.

Lead construction including alignable marker elements

A method of delivering a pacing lead may include locating a potential implantation site adjacent to or within the triangle of Koch region of a patient's heart. The method may include advancing a pacing lead to the potential implantation site. The pacing lead has an elongate body and a fixation element coupled to a distal portion and attachable to the right-atrial endocardium adjacent to or within the triangle of Koch region. The method may include implanting the pacing lead at the potential implantation site to or sense electrical activity of the left ventricle in the basal and/or septal region of the left ventricular myocardium of the patient's heart. The pacing lead may include a lumen configured to receive a guide wire. A sheath of a delivery system used to deliver the pacing lead may include two or more curves to facilitate implanting the pacing lead at the implantation site.

Delivery systems and methods for left ventricular pacing

A relatively compact implantable medical device includes a fixation member formed by a plurality of fingers mounted around a perimeter of a distal end of a housing of the device; each finger is elastically deformable from a relaxed condition to an extended condition, to accommodate delivery of the device to a target implant site, and from the relaxed condition to a compressed condition, to accommodate wedging of the fingers between opposing tissue surfaces at the target implant site, wherein the compressed fingers hold a cardiac pacing electrode of the device in intimate tissue contact for the delivery of pacing stimulation to the site. Each fixation finger is preferably configured to prevent penetration thereof within the tissue when the fingers are compressed and wedged between the opposing tissue surfaces. The pacing electrode may be mounted on a pacing extension, which extends distally from the distal end of the device housing.

Interventional medical device and method of use

An implantable lead system may include an adjustable lead assembly. The lead assembly may include a fixation member and an implantable lead slidably coupled to and rotatable relative to the fixation member. The implantable lead system may include a telescoping delivery system. The delivery system may include an outer catheter and an inner catheter slidably coupled to and rotatable relative to the outer catheter. The lead assembly may be implanted in a cardiac septal wall through the delivery assembly.

Interventional medical systems, devices, and methods of use

A connector sleeve includes a lumen adapted to receive a medical lead connector wherein a retention element engages a retention edge formed at a distal end of a connector element included on the lead connector. The connector sleeve further includes a contact element adapted to electrically engage the lead connector element within the lumen and an external conductive surface electrically coupled to the contact element and adapted for electrical engagement within the connector bore of an implantable medical device.

Implantable medical lead connector sleeves

A lead connector is terminated proximally by a connector pin and includes a circumferential array of connector pads, each connector pad coupled to an electrode via an elongated insulated conductor. A lumen of an adaptor is adapted to engage the lead connector and includes an electrical contact zone formed therein and positioned for coupling with a one of the array of connector pads, when the connector is engaged within the lumen, in order to facilitate electrical connection of a selected electrode corresponding to the one of the array of connector pads.

Multi-polar electrical medical lead connector system

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.

Deployable medical lead fixation system and method

A distal section of an implantable medical electrical lead body includes a pair of pre-formed arcuate segments between which an approximately straight segment extends. The approximately straight segment includes a first portion extending distally from a first of the pair pre-formed arcuate segments, a second portion extending from the first portion, a third portion extending from the second to a second of the pair pre-formed arcuate segments. An electrode is coupled to the second portion of the approximately straight segment, and the adjacent first portion has a stiffness which is less than that of the first of the pair pre-formed arcuate segments and preferably less than the stiffness of the third portion, so that, when the distal section of the lead body is implanted, for example, within a cardiac vein, the lead buckles to bring the electrode into closer contact with surrounding tissue.

Implantable medical electrical lead bodies providing improved electrode contact

A lead connector including a connector element array is fitted into a selected adaptor from a plurality of adaptors to electrically couple one or more elements of the connector element array, corresponding to one or more selected electrodes from an array of lead electrodes, to one or more contact zones of the selected adaptor in order to facilitate electrical connection with an implantable medical device.

Medical lead connector systems with adapters

In some embodiments, a method for optimizing cardiac resynchronization therapy (CRT) may include one or more of the following steps: (a) conducting a baseline measurement of a physical parameter of a patient before initiating CRT, (b) performing an implantation process including implanting a pacing device and pacing leads in the patient, the pacing device and pacing leads for providing the CRT, (c) initiating CRT on the patient, (d) measuring the physical parameter of the patient after initiation of the CRT, (e) comparing the measured physical parameter after initiation of the CRT to the baseline measure of the physical parameter to analyze the patient's response to the CRT, (f) adjusting the CRT during the implantation process to try and improve the patient's response to the CRT, and (g) repositioning at least one of the patient leads during the implantation process to try and improve the patient's response to the CRT.
