An implantable medical device system is configured to generate signals and deliver the signals to a heart of a patient. The implantable medical device system includes electronic circuitry configured to deliver cardiac pacing, couplings for an implantable medical lead receptacle, at least some of the couplings electrically connected with the electronic circuitry, a polymeric enclosure having the electronic circuitry contained therein, the polymeric enclosure formed of polymeric material filled around the electronic circuitry and couplings and forming the implantable medical lead receptacle. The implantable medical device may include a first cavity filled with a first material and a second cavity filled with a second material, and the first material is different than the second material.

Polymeric enclosure for implantable medical device

An implantable medical device configured to deliver pacing therapy, the implantable medical device including a device body configured to position within a heart, where the device body comprises a proximal body portion and a distal body portion and defines a longitudinal axis extending through the proximal body portion and the distal body portion, the proximal body portion is configured to rotate around the longitudinal axis relative to distal body portion, and a leadlet mechanically coupled to the device body, where the leadlet mechanically supports an electrode configured to deliver pacing therapy, and where in response to the proximal body portion rotating relative to the distal body portion, the device body is configured to alter an extension length of the leadlet.

Implantable medical device

A guide wire system configured to guide a medical device (e.g., a medical lead) to a target area within a patient. The guide wire system may be configured to penetrate and pass through a tissue wall in the patient to guide the medical device to the target area. The guide wire system includes a support section configured to expand to substantially maintain a position relative to the tissue wall. The guide wire system includes a pull wire configured to cause the support portion to expand. The expanded support section may provide counter-traction to a distal force on the tissue wall exerted by a medical device during, for example, fixation of the medical device to the target area, or other stages of an implantation. The support section is configured to re-establish an initial configuration for proximal withdrawal from the tissue wall.

Guide wire system

Various fixation techniques for implantable medical device (IMDs) are described. In one example, an assembly comprises an IMD; and a set of active fixation tines attached to the IMD. The active fixation tines in the set are deployable from a spring-loaded position in which distal ends of the active fixation tines point away from the IMD to a hooked position in which the active fixation tines bend back towards the IMD. The active fixation tines are configured to secure the IMD to a patient tissue when deployed while the distal ends of the active fixation tines are positioned adjacent to the patient tissue.

Implantable medical device fixation

A medical system includes an implantable medical device that carries a first electrode on a distal end of the implantable medical device and a return electrode. The implantable medical device is configured to be positioned within a heart. The implantable medical device further includes a leadlet including a proximal end and a distal end. The proximal end is attached to the implantable medical device, and the distal end is configured to penetrate tissue of the heart. The leadlet carries a second electrode, and a body of the leadlet between the proximal end and the distal end is configured to flex when the distal end is implanted in the tissue of the heart. The implantable medical device further includes a fixation device attached to the implantable medical device. The fixation device is configured to affix the distal end of the implantable medical device to the heart.

Dual chamber pacing

An example medical device includes a plurality of electrodes, therapy delivery circuitry, and processing circuitry configured to control the therapy delivery circuitry to deliver electrical stimulation to an intercostal nerve of a patient via at least two of the plurality of electrodes, wherein the electrical stimulation is delivered with stimulation parameters configured to suppress ventricular tachyarrhythmia of the patient, wherein the stimulation parameters comprise a stimulation frequency less than or equal to 40 hertz (Hz).

Inhibition of onset of cardiac tachyarrhythmia with intercostal nerve stimulation

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

The present disclosure is directed to a shuttle apparatus for detachably joining a catheter to a guidewire so that the joined catheter, extending alongside the guidewire, is in sliding engagement with the guidewire without extending around the guidewire. The apparatus comprises a collar member sized for mounting in sliding engagement around a length of the guidewire, the collar member having a longitudinal axis that approximately aligns along the length, when mounted thereabout, the length being defined between a proximal-most point of the guidewire and a distal point of the guidewire, the distal point being offset proximally from a distal-most point of the guidewire. The apparatus further comprises a plug member coupled to the collar member, the plug member having a longitudinal axis, and the plug member being sized to fit within an opening of the catheter for detachable engagement therewith.

Shuttle apparatus and associated systems and methods

Methods and systems for positioning a leadless pacing device (LPD) in cardiac tissue are disclosed. A delivery device is employed that comprises a proximal end, a distal end and a lumen therebetween sized to receive the LPD. The LPD has a leadlet extending therefrom that includes a means to fixate the leadlet to tissue. The delivery device comprises an introducer to introduce the LPD into the lumen of the delivery device. The LPD is loaded in the distal end of the lumen of the delivery device. The leadlet extends proximally from the LPD while the fixation means extends distally toward the LPD. A LPD mover is configured to advance the LPD out of the delivery device. A leadlet mover is configured to advance the leadlet out of the lumen delivery device and cause the leadlet to engage with cardiac tissue.

Compact implantable medical device and delivery device

Devices, systems, and methods deliver implantable medical devices for ventricular-from-atrial (VfA) cardiac therapy. A VfA device may be implanted in the right atrium (RA) with an electrode extending from the right atrium into the left ventricular myocardium. A flexible leed, or another probe, may be advanced to the potential implantation site and used to identify a precise location for implantation of a medical device, such as an electrode, leadlet, lead, or intracardiac device. Some methods may include locating a potential implantation site in the triangle of Koch region in the right atrium of a patient's heart; attaching a fixation sheath to the right-atrial endocardium in the potential implantation site; and implanting the medical device over a guide wire at the potential implantation site. An implantable medical device may include an intracardiac housing and a leadlet, which may be delivered by these methods.

VFA delivery systems and methods

An apparatus for forming a passageway through tissue includes a dilator mounted to a shaft, wherein the dilator includes a first portion, which has an increasing taper from a first outer diameter to a larger second outer diameter, and a second portion, which has a decreasing taper from the first portion to a distal end of the dilator, and which includes an external non-cutting thread formed along the decreasing taper. Lumens of the dilator and shaft provide a conduit for means to pierce through the tissue, for example, an elongate wire that includes a piercing tip. In some cases, the dilator first portion is expandable to, and contractible from, the larger second outer diameter, wherein the apparatus may include a spreading member configured to slide between the shaft and the first portion. The apparatus may be included in a system with an introducer sheath.
