    Abstract: An implantable medical device includes ventricular and atrial portions, and a flexible leadlet that extends therebetween. An open channel of the atrial portion, formed along a core thereof, is sized to receive the leadlet therein, when the leadlet is folded over on itself. An interventional medical system includes the device and a delivery tool; a tubular sidewall of the tool defines a lumen and has a tether extending therein. A slot formed in the sidewall extends proximally from an open end thereof, coincident with a distal opening of the lumen. When the atrial portion is contained within the lumen, a segment of the leadlet extends alongside the atrial portion; another segment of the leadlet, being folded over on itself, proximal to the atrial portion, has the tether engaged therewith. The slot may allow passage of the leadlet therethrough, when the atrial portion is positioned for deployment through the distal opening.

    Abstract: An example fixation component for an implantable medical device (IMD) includes a base and a plurality of tines configured be deployed with a target deployment stiffness to engage tissue a target implant site while maintaining a target deflection stiffness after deployment. The base defines a longitudinal axis of the fixation component and is fixedly attached near the distal end of the IMD. Each tine is spaced apart from one another around a perimeter of the distal end of the IMD and extend from the base. A shape of each tine is selected to control each of the target deployment stiffness and target deflection stiffness.

    Abstract: Methods and systems of making a medical electrical lead type having a set of tines. A system for implantation of a lead medical electrical lead in contact with heart tissue, comprises an elongated lead body; a set of curved tines mounted to and extending from a distal end of the lead body, the tines having a length (dD) and an effective cross sectional area, and a delivery catheter. The delivery catheter encloses the lead body and has a distal capsule portion enclosing the tines. The tines exerting a spring force against the capsule and provide a stored potential energy. The tines when so fixated in the tissue provide a fixation energy. The deployment energy and the fixation energy of the tines are equivalent.

    Abstract: An isolated heart-lung preparation is provided, which comprises an excised heart with one or two lung(s) and in which essentially normal pumping activity of all four chambers of the heart is preserved, allowing for the use of the preparation in conjunction with investigations of electrode leads, catheters, ablation methods, cardiac implants and other medical devices intended to be used in or on a beating heart. The isolated preparation comprises i.a. a support apparatus, a perfusate reservoir (246), an oxygenator (244), perfusion pumps (240, 242) and a ventilator (500). The isolated preparation may additionally comprise an optical viewing scope (224) inserted into one or more of the chambers of the heart. The preparation and recordings of the preparation may be used in conjunction with the design, development and evaluation of devices for use in or on the heart and/or lungs, as well as for use as an investigational and teaching aid to assist physicians and students in understanding the operation of the cardiopulmonary system.
