摘要： A system and method for simply and reliably determining the location and orientation of a medical device within a patient's body. A medical device, such as a catheter, has bending indicators on or imbedded in its wall, and passes through an anatomical reference of known orientation relative to a target site within the patient. Information from the tube bending indicators permits determination of the orientation of a feature, such as an orifice, at the distal end of the medical device relative to the anatomical reference. From the known orientation of the anatomical reference, and information on the location and orientation of the distal end of the medical device obtained from fluoroscopic imaging from a single direction, the physician may reliably determine the orientation of the distal feature relative to the target site, eliminating the need for imaging from multiple directions.

摘要： A catheter handpiece apparatus and method for delivering a desired dose with minimal potential for contamination of the injected substance and rapid, accurate delivery of the desired dose. In one embodiment, a carriage assembly affixed to an inner lumen is slidably located within a handpiece housing equipped with an outer lumen. The carriage assembly receives a dose carpule. An actuator knob cocks the carriage assembly and a spring-powered actuator mechanism. After the catheter is maneuvered to a desired injection site and a desired dose is set, depressing a first trigger causes the inner lumen tip to extend beyond the outer lumen into the injection site. Depressing a second trigger causes the actuator mechanism to push the desired dose from the dose carpule through the inner lumen into the injection site. A second embodiment provides a catheter handpiece with a carriage assembly cocking lever and an operator-powered dose delivery mechanism.

摘要： A catheter system comprises a catheter comprising a distal portion, a proximal portion and an inner shaft. The inner shaft comprises a medical device receiving region for receiving and carrying a medical device. The retaining device is at least partially constructed of an electroactive polymer. The retaining device is located on or adjacent to the medical device receiving region. The electroactive polymer of the retaining device has an activated state and an inactivated state. The retaining device is capable of retaining a medical device to the catheter and releasing the medical device from the catheter by transitioning between the activated state and the inactivated state.

摘要： The invention provides devices that can be used to deliver a therapeutic agent to a treatment site within the vessel of a patient at increased pressure, while limiting the contact with and pressure placed on the vessel walls. Devices according to the invention include an expandable structure arranged around and on a tube having a lumen. The expandable structure may include a sealing ring that makes contact with the interior surface of a vessel to prevent or decrease fluid flow during delivery of a therapeutic agent. This allows delivery of a therapeutic agent with decreased risk of injury to the treatment site. The invention also provides for large lumen diameters, preventing shearing stress on therapeutic agents such as cell slurries.
