A cardiac support device includes a jacket and elastic attachment structure for self-securing the jacket to a heart. The attachment structures can include undulating metal and polymer elements, a silicone band and elastomeric filaments on a base end of the jacket.

Self-adjusting attachment structure for a cardiac support device

A method for implanting a cardiac support device (CSD) on a patient's heart. An amount of contrast agent sufficient to cause structures on the heart to be visible upon fluoroscopic or other imaging is introduced into the pericardial space surrounding the heart. The heart and contrast agent are imaged to provide a visual indication of the location of the structures of the heart. The CSD is placed on the heart using the visual indications provided by the imaging.

Pericardial space imaging for cardiac support device implantation

A heart size measuring tool includes a tubular body, a flexible measuring cord having length indicia, a measuring cord support mechanism movable between retracted and extended states with respect to the body, and an actuating mechanism to move the measuring cord support mechanism. When in the retracted state the measuring cord support mechanism is positioned within the tubular body with the measuring cord in a collapsed position. When the measuring cord support mechanism is in the extended state the measuring cord extends around a portion of a heart to be measured. A scale on the body can be used in connection with the indicia on the measurement cord to provide a reading of the heart size.

Intra-operative heart size measuring tool

A cardiac support device including a jacket and elastic attachment structure for self-securing the jacket to a heart. The attachment structures can include undulating metal and polymer elements, a silicone band and elastomeric filaments on a base end of the jacket.

A small diameter, shielded, fine wire glass fiber conductor which is capable of transmitting optical and electrical signals in environments with electromagnetic interference or radio frequency interferences. The conductor includes a fiber core, a first insulation layer, a conductive layer, a second insulation layer, a shielding layer, and an outer coating. Applications include use in aerospace, automotive, and other vehicles as well as potential use in electrostimulation devices, such as pacemaker leads, vascular guidewires and other medical applications.

Optical fiber-fine wire conductor and connectors

Durable fine wire electrical conductors are robust, durable, small in profile, and light weight, yet capable of operating under extreme environmental conditions. Formed of a glass, silica, sapphire or crystalline quartz fiber core with a metal coating and one or more polymer layers, a unipolar electrical conductor can have an outer diameter as small as about 300 microns or even smaller. The metal buffer coating may be deposited directly on the glass/silica fiber, or upon an intermediate layer between the glass/silica fiber and metal, consisting of carbon and/or polymer. The resulting metallized glass/silica fibers are extremely durable, can be bent through small radii and will not fatigue even from millions of iterations of flexing. Bipolar electrical conductors can include several insulated metallized glass/silica fibers residing side by side, or can be coaxial with two or more insulated metal conductive paths. An outer protective sheath of a flexible polymer material can be included.

Durable fine wire electrical conductor suitable for extreme environment applications

Various aspects of the present disclosure are directed toward an implantable electrostimulation device, a plurality of sensing and pacing elements, and a fine wire lead extending in a sealed relationship from the electrostimulation device and to the plurality of sensing and pacing elements. The fine wire lead includes multiple discrete conductors and a drawn silica or glass fiber core, a polymer cladding on the drawn silica or glass fiber core, and a conductive metal cladding over the polymer cladding. Additionally, the fine wire lead simultaneously delivers different electrical signals or optical signals between the sensing and pacing elements and the electrostimulation device.

A system for delivering an antimicrobial agent into the lumen of a trans-dermal catheter. In an embodiment, the system comprises an elongate member configured for insertion into a lumen of a catheter; an expandable portion of the elongate member, said expandable portion configured to increase in diameter upon exposure to an aqueous fluid; and an antimicrobial composition positioned to be delivered into the catheter. In another embodiment, the system comprises an elongate member configured for insertion into a lumen of a trans-dermal catheter, said elongate member comprising a hydrogel; and an antimicrobial composition positioned to be delivered into the catheter; wherein the elongate member defines a volume of liquid that is at least substantially contained within the lumen of the trans-dermal catheter.

Device for delivery of antimicrobial agent into trans-dermal catheter

A cardiac constraint device comprising a jacket of biological compatible material and an adjustment member. The jacket is adapted to be secured to the heart to snugly conform to an external geometry of the heart and assume a maximum adjusted volume to constrain circumferential expansion of the heart beyond the maximum adjusted volume during diastole and to permit unimpeded contraction of the heart during systole. The adjustment mechanism is configured to alter the internal volume defined by the jacket after the jacket is secured to the heart. The invention also provides a method for treating cardiac disease.

Cardiac disease treatment and device

A device for delivery of a cardiac support device for treating cardiac disease of a heart includes a multistage deployment mechanism and an actuating mechanism for controlling the positions of the deployment mechanism. The deployment mechanism is operable to change between a retracted state and an extended state, and includes a plurality of independent stages, including, in one embodiment, a first stage including a guide structure for location adjacent a portion of the patient's heart when in the extended state. A second stage is movably coupled to the first stage, and is guided by the guide structure between the retracted and extended states. The second stage further releasably engages and supports the cardiac support device and positions the cardiac support device at the desired implantation location, guided by the guide structure of the stage. In some embodiments, the deployment mechanism may include additional stages. The actuating mechanism drives the deployment mechanism between the retracted and extended states, and independently controls the positions of the multiple stages of the deployment mechanism.

A method for managing the pericardium during intra-pericardial procedures such as the delivery of cardiac support devices. One embodiment of the method includes making an incision through the pericardium to provide access to the pericardial space, and inserting a plurality of strips of lubricious material into and through the incision. The strips of material are spaced around the edges of the incision to form a tubular barrier against the pericardium. End portions of the strips of material in the pericardial space are expanded away from the body to form a lip that lines the inside of the pericardium around the incision.
