Abstract: An injection catheter is provided with a piezoelectric ultrasound emitting device atits distal end, capable of emitting ultrasound of different energy levels. It can be used toimage the location of penetration of an internal organ of a patient by the catheter needle,by supply of echocontrast material through the needle and analysis of the ultrasoundreflections therefrom. It c an also be used to cause tissue perturbation or disruption at theimaged locatio n, e.g. to initiate tissue angiogenesis, by choice of suitable ultrasoundenergy level of emission, and for delivery of therapeutic substances such as DNA to thedisrupted tissue, for better uptake in gene therapy.

Abstract: Cell-based gene transfer is effected by administering transfected fibroblast cells, from dermal or other origins, containing an expressible transgene coding for an angiogenic factor or other therapeutic factor, into the pulmonary circulation of a patient, where the cells express and secrete expression products of the transgene to act locally at the site of expressio n, and in some cases to be conveyed by the patient's circulation to other body organs. The process is especially useful in treatment of pulmonary hypertension by means of expressed angiogenic factors.

Abstract: Cell-based gene transfer is effected by administering transfected cells containing an expressible transgene into the pulmonary system of a patient, where the cells express and secrete expression products of the transgene directly into the pulmonary system. Also provided is the use of angiogenic factors in treatment of pulmonary hypertension.
