Abstract
Methods and systems related to sealing punctures in blood vessels (such as following an angio or PTCA procedure) are disclosed. The invention provides a system to sense the location of a distal portion of a member within a body. The system includes an introducer portion having a distal end adapted to be placed within a body and a pressure sensor. The pressure sensor is in fluid communication with the distal end and is adapted to provide a pulsation which can be sensed by an operator when the distal end is placed within a pulsating portion of the body.
