    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 A biomaterial is then delivered to the treatment site as the delivery device is withdrawn from the treatment site to form the reinforcement regions.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.
