An operating room cable assembly for electrically coupling at least one implantable electrical stimulation lead to a trial stimulator includes an elongated body; a trial stimulator connector disposed at one end of the elongated body; and a lead connector disposed at another end of the elongated body. The lead connector can include one or more buttons that can be pushed to load a lead into the lead connector and released to retain the lead. Alternatively, the lead connector can include a lever that can be operated to load the lead. A further alternative is a slider with a lead engagement element that can be slid between positions allowing loading of a lead and engagement of the lead. Other alternatives include a lead connector with doors that can swing open to allow loading of a lead or a collet/sleeve that can be tightened on the lead.

Representative embodiments of the present invention provide for novel, minimally invasive implantable devices and methods for targeted tissue drug delivery of cardiovascular drugs.

A lead assembly and associated process include a lead and an integrated feature that facilitates extraction of the lead from the associated body passage. The integrated feature in one embodiment is a sheath received between the associated body passage and received over the lead. The sheath has a first portion extending from adjacent the proximal end to adjacent the distal end of the lead, where the first portion has an inner surface facing with the lead outer surface and the first portion having an outer surface facing radially outward from the lead outer surface. A second portion of the sheath extends from adjacent the distal end to adjacent the proximal end of the lead. The second portion has an inner surface received over the outer surface of the first portion, and the second portion further having an outer surface abutting an inner surface of the associated body passage that receives the lead therein. The integrated feature is alternatively a wire, band, or spoke assembly.

An apparatus for securing a sensor at the heart is formed based on a modified, branched, pacemaker lead to provide a heart anchor lead where two anchors are coupled to a single main lead rather than there being just a single anchor. Thus, the proposed heart anchor lead comprises a single main lead, a sensor included within the main lead, in which the sensor has a distal end and a proximal end, a first anchor coupled to the distal end of the sensor and extending outward from the distal end of the sensor, and a second anchor coupled to the proximal end of the sensor and extending outward from the proximal end of the sensor in a direction that forms an angle with the first anchor. The heart anchor lead can optionally also have a pacemaking function.

A device implantable on a target of interest of a subject for pacemaker, neuromodulator, and/or defibrillator therapy comprises a wireless power harvesting unit configured to deliver power via resonant inductive coupling to the target tissue for stimulation in a manner that eliminates need for batteries and allows for externalized control without transcutaneous leads. The device relies exclusively on materials that resorb when exposed to biofluids in a time-controlled manner via metabolic action and hydrolysis. The materials and design choices create a thin, flexible, and lightweight form that maintain excellent biocompatibility and stable function throughout a desired period of use. Over a subsequent timeframe following the completion of therapy, the devices disappear completely through natural biological processes. These characteristics and a miniaturized geometry facilitate full implantation into the body to eliminate the need for percutaneous hardware, which thereby minimizes the risk of device-associated infections and dislodgement.

An implantable defibrillator heart pump includes an integrated replaceable difibrillator device. The defibrillator heart pump includes a pump head, a percutaneous line/combined drive line, a pair of implanted cardioverter defibrillator electrodes and an outflow prosthesis.

Representative embodiments of the present invention provide for novel, minimally invasive implantable devices and methods for targeted tissue drug delivery of cardiovascular drugs.

A device, system, and method for delivering energy to tissue. In particular, the present invention relates to a system and method for enhancing lesion formation without arrhythmogenic effects within relatively thick target tissues, such as the ventricles of the heart. In one embodiment, charge-neutral pulses and non-charge-neutral pulses may be delivered to induce the formation of electrolytic compounds that enhance cell death at the treatment site. Additionally or alternatively, tissue at the treatment site may be heated to sub-lethal temperature before ablating the tissue.

A method for sealing a tissue opening includes inserting a trocar tube including a folded sealing device disposed within the trocar, and guiding the trocar tube through an opening in a myocardium into a patient's ventricle, the sealing device can include an elongated elastic member having a distal and a proximal end, a proximal umbrella shaped braiding extending radially from the elongated elastic member, the proximal braiding being positioned at the proximal end of the elastic member, wherein the proximal braiding includes a proximal disc disposed therein having a proximal disc thread disposed therethrough such that a user can pull the proximal braiding, and a distal umbrella shaped braiding extending radially from the elongated elastic member and being positioned at the distal end of the elastic member opposite to the proximal braiding.
