An apparatus includes a container and a medical device configured to be implanted on or within the recipient's body. The medical device is contained within a sealed region of the container prior to implantation of the medical device. The medical device includes at least one housing containing circuitry and a plurality of signal ports spaced from the at least one housing. The plurality of signal ports is configured to be in communication with a portion of the recipient's body. The medical device further includes an elongate assembly extending from the at least one housing and configured to transmit signals between the circuitry and the plurality of signal ports. The assembly has at least one portion having a shape while the medical device is within the sealed region, the shape including at least one loop and/or a plurality of serpentine turns.

The present disclosure relates to devices and methods for cardiac pacing therapy. Disclosed herein are methods for His bundle cardiac pacing; cardiac leads and leadless cardiac pacemakers that enables pacing and sensing of the His bundle as well as the right atrium and right ventricle; and delivery sheaths for placing the cardiac lead or leadless cardiac pacemaker in the heart. The devices and methods disclosed increase the success at which His bundle pacing can be implemented.

Devices and methods can be used for artificial cardiac pacing and/or resynchronization. For example, this document provides improved electrodes for stimulating and sensing electrical activity of the heart, and provides pacing and resynchronization systems incorporating such electrodes. While the devices and methods provided herein are described primarily in the context of pacing, it should be understood that resynchronization can additionally or alternatively be performed in an analogous manner, and that the scope of this disclosure includes such subject matter.

A medical system includes an implantable medical device configured to be positioned within an atrium of a heart. The implantable medical device includes a housing carrying a return electrode, a first leadlet, a second leadlet, and a fixation device. The medical system may be configured to deliver a variety of therapies, including one or more of ventricle-from-atrium cardiac therapy (“VfA therapy”), left bundle branch pacing therapy (“LBB therapy”), or cardiac resynchronization therapy (“CRT”).

Systems and methods involving implants positioned within implant pockets through minimally invasive entrance incisions, along with related implants. In some implementations, implants may be folded, rolled, or otherwise compressed to fit within subcutaneous implant pockets, after which they may be decompressed to fit within an implant pocket having one or more dimensions substantially larger than the entrance incision. Such implants may be used for a variety of purposes, including generating electrical energy for various other implants located throughout the body.

A device for therapeutic neuromodulation in a nasal region can include, for example, a shaft and a therapeutic element at a distal portion of the shaft. The shaft can locate the distal portion intraluminally at a target site inferior to a patient's sphenopalatine foramen. The therapeutic element can include an energy delivery element configured to therapeutically modulate postganglionic parasympathetic nerves at microforamina of a palatine bone of the human patient for the treatment of rhinitis or other indications. In other embodiments, the therapeutic element can be configured to therapeutically modulate nerves that innervate the frontal, ethmoidal, sphenoidal, and maxillary sinuses for the treatment of chronic sinusitis.

An electrical feedthrough assembly, which is configured to be mounted on a housing of a leadless biostimulator, comprises an electrode body including a cup having an electrode wall extending distally from an electrode base around an electrode cavity, an electrode tip mounted on a distal end of the electrode body, and a filler in the electrode cavity between the electrode base and the electrode tip, wherein the filler includes a therapeutic agent. The electrode tip is configured to be placed in contact with target tissue to which a pacing impulse is to be transmitted by the leadless biostimulator. A pin extends proximally from the electrode base, wherein the pin is configured to be into contact with an electrical connector of an electronics assembly within the housing of the leadless biostimulator.

Disclosed herein is an implantable pulse generator for administering electrotherapy via an implantable lead. The pulse generator includes a housing and a header connector assembly coupled to the housing. The header connector assembly includes a connector assembly and a header enclosing the connector assembly. The connector assembly includes a support and a connector receptacle. The support extends at least partially about the connector receptacle and is at least partially responsible for having prevented injection molding material from entering the connector receptacle when the injection molding material was injection molded about the connector assembly in forming the header.

A biostimulator, such as a leadless cardiac pacemaker, including coaxial fixation elements to engage or electrically stimulate tissue, is described. The coaxial fixation elements include an outer fixation element extending along a longitudinal axis and an inner fixation element radially inward from the outer fixation element. One or more of the fixation elements are helical fixation elements that can be screwed into tissue. The outer fixation element has a distal tip that is distal to a distal tip of the inner fixation element, and an axial stiffness of the outer fixation element is lower than an axial stiffness of the inner fixation element. The relative stiffnesses are based on one or more of material or geometric characteristics of the respective fixation elements. Other embodiments are also described and claimed.
