摘要： A method and apparatus for treating a stricture in a body lumen. The method comprises (a) sensing pressure being exerted by a treatment device on the stricture, (b) determining if enough force is being exerted on the stricture, (c) if enough force is being exerted on the stricture, timing the application of enough force, (d) determining if too much force is being exerted by the treatment device on the stricture, (e) if too much force is being applied to the stricture, decrementing the force being applied to the stricture, (f) determining if not enough force is being applied to the stricture, (g) if not enough force is being applied to the stricture incrementing the force being applied to the stricture, and (h) repeating (a)-(g) until (i) a desired pressure has been maintained on the tissue for a desired time. The apparatus comprises a device for exerting pressure on the stricture, a controller for controlling the amount of pressure the device exerts on the stricture, and a pressure sensor for sensing the pressure being exerted on the stricture by the device.

摘要： A surgical instrument system for use in a surgical procedure is disclosed. The surgical instrument system may include an instrument configured to puncture the tissue of a patient and detect when the instrument has entered a lumen of the patient's body. The surgical instrument system may include one or more capacitive sensors near a tip of a needle and electrical circuitry to monitor the capacitance of the capacitive sensors. The capacitance of the capacitive sensors may change as the needle is inserted into different tissue of lumens of the patient's body, allowing for the position of the needle to be determined based on analysis of the capacitance of the capacitive sensors.

摘要： A surgical instrument system for use in a surgical procedure is disclosed. The surgical instrument system may include an instrument configured to puncture the tissue of a patient and detect when the instrument has entered a lumen of the patient's body. Liquid may be present in the lumen or the lumen may be devoid of liquid or tissue. The instrument is configured to determine when the needle tip is engaged with a portion of patient's tissue and determine when the needle tip has exited that portion of the patient's tissue by detecting changes in properties of the tissue, specifically, electrical resistance.

摘要： A surgical instrument system for use in a surgical procedure is disclosed. The surgical instrument system may include an instrument configured to puncture the tissue of a patient and detect when the instrument has entered a lumen of the patient's body. The surgical instrument system may include a balloon catheter including a percutaneous dilation balloon and a moveably positionable retainer. The retainer is configured to move relative to the balloon such that upon inflation of the balloon when the balloon is positioned in the opening in the patient's tissue, the retainer engages the patient's tissue to inhibit movement of the balloon catheter.
