摘要： Methods and systems are disclosed for selective drug or fluid delivery in a lumen through a coating or fluid delivery channels. One system includes an elongate catheter having a proximal end and a distal end with an axis therebetween, the catheter having a radially expandable balloon near the distal end and an energy delivery portion proximate the balloon for transmission of energy, a thermally changeable coating having a releasable drug coupled to the balloon, the thermally changeable coating being oriented to be urged against the body tissue when the expandable balloon expands and an energy source operatively coupled to the energy delivery portion configured to energize the energy delivery portion to heat and liquefy the thermally changeable coating to release the drug to the body tissue.

摘要： Medical devices and methods for making and using medical devices are disclosed. An example method may include a method for heating a body tissue region adjacent to a body lumen. The method may include positioning an energy delivery portion of a catheter within the lumen and engaging the body lumen with the energy delivery portion. Engaging the body lumen may complete a plurality of circuits. The method may also include determining a pulse characteristic in response to a thermal property of a first tissue type and applying controlled pulsed electrical energy with the pulse characteristic from the energy delivery portion through the plurality of circuits.
