Linear delivery system for deployment of a detachable balloon at a target site in vivo

摘要

A linear delivery system and method for deployment of a detachable balloon at a target site in a patient in vivo is disclosed. The system includes a unitary sheath assembly having a retractable shaft and base, and a balloon delivery device configured for insertion through the lumen of the sheath assembly. The linear method of delivery overcomes disadvantages and limitations caused by undesirable movement of the assembly or separation of the catheter from the delivery system during inflation of the balloon. The linear delivery system further includes properties that increase the ease of use and stability of the device so as to reduce the effort required by the physician and discomfort experienced by the patient during deployment of a detachable balloon.
