摘要： A delivery system for delivering a therapeutic agent to a patient includes a catheter, a stop feature, a container and a bar. The catheter has a proximal end and a distal end and includes a body defining a lumen that extends to the distal end of the catheter. The stop feature is in proximity to the distal end of the catheter. The container is configured to house the therapeutic agent and is insertable and slidably disposable in the lumen of the catheter. The container is also configured to engage the stop feature of the catheter. The bar is slidably disposable in the lumen of the catheter. Sliding of the bar distally in the lumen forces the therapeutic agent out of the container and out of the lumen when the container is engaged with the stop feature. The stop feature is configured to inhibit the container from exiting the lumen.

摘要： A method for adjusting delivery of a therapeutic fluid to a patient suffering from or at risk of pulmonary arterial hypertension includes introducing the therapeutic fluid to a patient via a catheter at a predetermined rate. The catheter is positioned to deliver the fluid to the right ventricle or the pulmonary artery. The catheter a one-way valve configured to allow the fluid to flow from the catheter to the target location. The method further includes monitoring pressure of the target location by monitoring internal catheter pressure, and adjusting the rate at which the therapeutic fluid is introduced to the catheter based on the monitored pressure. The rate at which the fluid is introduced to the catheter is increased if internal catheter pressure increases, and the rate at which the fluid is introduced to the catheter is decreased if the internal catheter pressure decreases.

摘要： The current invention discloses a method for treating infracted/ischemic injury to a myocardium by injecting a substance into the myocardium. The injected substance helps to prevent negative adaptive remodeling by providing mechanical reinforcement or mechanical reinforcement combined with biological therapy. A number of substances for injection are disclosed, including multi component substances such as platelet gel, and other substances. The substances disclosed may contain additives to augment/enhance the desired effects of the injection. The invention also discloses devices used to inject the substances. The devices can include means for ensuring needles do not penetrate beyond a desired depth into the myocardium. The devices can also include needles having multiple lumens such that the components of the platelet gel will be combined at the injection site and begin polymerization in the myocardium.
