Treating pulmonary embolism

Pulmonary embolisms occur as a result of the obstruction of one or more pulmonary arteries by a clot. If the embolism is massive, it requires emergency treatment. But fibrinolytics (drugs that dissolve clots) present risks of hemorrhage and surgery is difficult. Other types of intervention are sought after.

One team developed an ultrasound generator attached to the end of a catheter that is capable of destroying in vitro a 90% blood clot in less than 4 hours without fibrinolytic drugs or significant local heating.

Other in vitro and animal tests are planned before considering trials in the patient.
