A cardiac device for implantation proximate an exterior of a heart, the cardiac device including an inflatable bladder including an inner wall and an outer wall, wherein the inner wall itself is more expandable than the outer wall itself such that the inflatable bladder itself is configured to deform substantially inwardly to exert localized pressure against a region of the heart when the inflatable bladder is positioned adjacent the region of the heart and inflated.

An access device for a heart chamber, a removable hemostatic valve unit, and a system including a cardiac assist unit are disclosed. In examples, the access device) includes an apical base plate and a sealing unit configured to provide a separation of a wet zone from a heart chamber and a dry zone with a gaseous environment outside of said heart chamber inside a patient body at the same time.

Methods and devices that prevent stasis in the LAA by either increasing the flow through the LAA or by closing off or sealing the LAA. Increasing the flow is accomplished through shunts, flow diverters, agitators, or by increasing the size of the ostium. Closing off the LAA is accomplished using seals or by cinching the LAA.

A medical device delivery system including a delivery sheath that includes an internal lumen, and a plurality of delivery arms contained within the internal lumen of the delivery sheath and extending along a longitudinal axis of the internal lumen of the delivery sheath, wherein distal ends of the delivery arms include fasteners configured to engage with a basal structure of a medical device and a apical structure of the medical device, wherein the delivery arms are attached to delivery arm controls that are configured to advance the delivery arms and the medical device attached thereto out from a distal end of the delivery sheath, and removable release wires or release lines configured to engage with the fasteners to hold the basal structure and the apical structure in place at the fasteners. Also disclosed are methods of delivering a medical device to a subject including inserting a distal end of the medical device delivery system through an incision in the skin of subject, and deploying a medical device engaged with the delivery arms of the medical delivery system to within the body of the subject.

Percutaneous access devices (PAD), bandages, or other implantable medical devices are provided that are equipped with filters, environmental controls, and sensors that promote the formation of a natural biologic seal between the skin and the device to form a barrier to microbial invasion into the body. Levels of humidity and pressure are monitored and dynamically controlled to optimize wound closure about an implanted device or when a PAD is not present a wound itself. Methods and systems for actively assessing wound closure are incorporated into the design of percutaneous skin access devices (PAD), bone anchors, or a wound dressing or bandage alone without at PAD. Pressure and humidity sensors provide active feedback for making changes to the ecology of the wound site or PAD insertion site. A filter is used to aerate the wound while also preventing pathogens in the ambient air from reaching the wound.
