    Abstract: Treatment of heart failure in a patient by electrically modulating both the sympathetic and parasympathetic autonomic cardiac nerve fibers that innervate the patient's heart at an extravascular site in the pericardial space of the heart. The extravascular site is any suitable single location inside the chest cavity that carries both sympathetic and parasympathetic cardiac nerves such as the cardiac plexus or the pericardial transverse sinus or any two separate extravascular sites with one site carrying predominantly sympathetic cardiac nerves and the other site carrying predominantly parasympathetic cardiac nerves for electrically modulating the balance of autonomic cardiac nerve control. Physiologic inputs from a neuromodulation system's own sensors or from separate implanted or external cardiovascular hemodynamic sensor systems can be used for closed loop control over the balance of sympathetic and parasympathetic cardiac autonomic effects on the patient's cardiac function in real time response to chronic and transient physiologic needs.

    Abstract: One aspect of the present disclosure relates to an embolic filter device configured for placement in a blood vessel to capture emboli during a medical procedure. The embolic filter device can include an expandable frame member and a membrane. The expandable frame member can include a radial support member operably connected to first and second longitudinal struts, and an engaging portion extending between the first and second longitudinal struts. The engaging portion can be shaped and configured to temporarily receive, and sealingly mate with, a portion of an endovascular catheter during the medical procedure. The membrane can be securely connected to the frame member and define a collection chamber for captured emboli. The membrane can be configured to cover substantially all of the cross-sectional area of the blood vessel when the embolic filter device is deployed in the blood vessel.

    Abstract: A needle catheter configured for injecting an agent into a wall of a patient's body cavity, which directs a needle from the distal tip of the catheter into the wall of the body cavity at an angle relative to the axis of the shaft. The resulting angled injection pathway improves the retention of the agent in the body cavity wall, while keeping a distal section of the catheter substantially perpendicular to the body cavity wall for optimal push against the tissue at the injection site.

    Abstract: A reinforcement region is formed within the myocardium by introducing a delivery device through a vessel wall to a treatment site within a myocardium. A biomaterial is then delivered to the treatment site as the delivery device is withdrawn from the treatment site to form the reinforcement regions. Formation of the reinforcement region may further include introducing a delivery device through a vessel wall to a region within a myocardium such that the delivery device is positioned within the myocardium substantially parallel to a wall of the myocardium. A biomaterial may be delivered into a space formed within the region by the delivery device. The reinforcement region may be formed around an infarct tissue region of a myocardium to reinforce the damaged tissue.

    Abstract: A bioscaffolding can be formed within a post-myocardial infarct region sufficient to cause attenuation of a rate of myocardial infarct expansion. A bioscaffolding may further be formed in the post-myocardial infarct region to cause an increase in posterior left ventricular wall thickness. The gel or bioscaffolding can be formed from a mixture of gel components of different gelation systems. For example, a bioscaffolding can be formed by mixing at least two different components of at least two different two-component gelation systems to form a first mixture and by mixing at least two different components (other than the components that make up the first mixture) of the at least two different two-component gelation systems to form a second mixture.
