20100069844 | Devices and Methods for Interstitial Injection of Biologic Agents into Tissue - Apparatus and methods for injecting biological agents into tissue. Devices are provided having elongate shafts and distal injection heads for driving needles into tissue and injecting medical agents into the tissue through the needles. A longitudinal force directed along the shaft can be translated to a needle driving force. Some devices provide controllably variable needle penetration depth. Devices include mechanical needle drivers utilizing four link pantographs, rack and pinions, and drive yokes for driving a first needle bearing body toward a second tissue contacting body. Other devices include inflatable members for driving and retracting needles. Still other devices include magnets for biasing the needles in extended and/or retracted positions. The invention includes minimally invasive methods for epicardially injecting cardiocyte precursor cells into infarct myocardial tissue. | 03-18-2010 |
20100114059 | SYSTEM AND METHOD FOR DELIVERY OF BIOLOGIC AGENTS - 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. | 05-06-2010 |
20100274221 | PRESSURE MONITORING TO CONTROL DELIVERY OF THERAPEUTIC AGENT - 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. | 10-28-2010 |
20110123593 | SELF-FIXATING SCAFFOLDS - A self-fixating scaffold delivers therapeutic material to tissue for treating various diseases/conditions. A scaffold holds the therapeutic material and is implanted into the tissue. A fixation element anchors the scaffold in the tissue making the scaffold less likely to become dislodged. | 05-26-2011 |
20120234877 | Infant Carrier - An apparatus to carry an infant against a chest of a person that includes a central panel, a first side panel, a second side panel, a first infant seat and a fastening mechanism. The first side panel is attached to the central panel and has a first aperture formed therein. The second side panel is attached to the central panel and has a second aperture formed therein. The first infant seat is attached to the central panel. The first infant seat is adapted to receive a portion of the infant. The fastening mechanism is operably attached to at least one of the first side panel and the second side panel for securing the first side panel and the second side panel around a torso of the person. | 09-20-2012 |
