Title: Pericardial therapeutic and diagnostic agent delivery
Inventor: ZIPES DOUGLAS P
IPC: A61K48/00
Filed: 1996-05-31
Abstract: A method for treating a patient's heart which comprises delivering a gene therapy agent into the pericardial sac around the patient's heart. The agent is introduced surgically or by transvascular means such as a catheter which has been introduced percutaneously or otherwise. Introducing the gene therapy agent into the pericardial sac contains the agent, allowing high concentration of the agent adjacent large regions of the epicardium and pericardium without spillage or systemic distribution to other organs or tissues. The gene therapy agents of this invention comprise vectors for transferring genetic information to the epicardial cells in vivo or harvested cells which have been genetically engineered in vitro. In a preferred embodiment, a catheter is percutaneously introduced, such as through the femoral artery, and guided upstream into the left ventricle. The distal end of the catheter advanced until it penetrates through the epicardium so that agent can be introduced into the pericardial space. Access to the pericardium may also be gained intraoperatively or through a thoracotomy. Additionally, the method may comprise employing a viscosity enhancer in conjunction with the gene therapy agent to affect the kinetics of the agent-host cell interaction and thus improve the rate and efficiency of transduction.

Inventor: BEAUJOT NORBERT
IPC: A01C5/06
Filed: 1998-06-12
Abstract: The invention provides a guidance system for guiding a no-till seeder such that the furrow openers of the seeder travel along the field between the standing stubble rows from the previous crop, thereby leaving the stubble rows standing and reducing plugging of the seeder with crop residue. The guidance system comprises sensing means to sense the standing stubble rows from the previous crop and to send a steering signal in response to changes in the relative position of the seeder to the standing stubble rows; and adjusting means to adjust the travel path of the seeder in response to the steering signals. The sensing means is a wedge-shaped pan adapted to ride along the ground between two standing stubble rows from the previous crop. Lateral movement of the pan sends a steering signal to the adjusting means, conveniently a hydraulic cylinder, via a solenoid valve which cylinder moves the seeder to the left or right relative to the towing vehicle. A furrow sensor is also provided.

Abstract: A fluidic medical diagnostic device permits measurement of analyte concentration or a property of a biological fluid, particularly the coagulation time of blood. The device has at one end a sample port for introducing a sample and at the other end a bladder for drawing the sample to a measurement area. A channel carries the sample from the sample port to the measurement area, and a stop junction, between the measurement area and bladder, halts the sample flow. The desired measurement can be made by placing the device into a meter which measures a physical property of the sample - typically, optical transmittance - after it has interacted with a reagent in the measurement area.
