Abstract: Systems, methods, apparatus and devices for performing improved gynecologic and urologic procedures are disclosed. An access sheath is provided with at least one lumen, and a lens attached thereto. The various embodiments enable procedures to be performed outside the hospital setting, such as in a doctor's office or clinic.

Abstract: Systems, methods, apparatus and devices for performing improved gynecologic and urologic procedures are disclosed. The system is configured to permit simultaneous tissue cutting and removal from a target site. The various embodiments enable procedures to be performed outside the hospital setting, such as in a doctor's office or clinic.

Abstract: Systems, methods, apparatus and devices for performing improved gynecologic and urologic procedures are disclosed. The system and devices provide simplified use and reduced risk of adverse events. Patient benefit is achieved through improved outcomes, reduced pain, especially peri-procedural pain, and reduced recovery times. The various embodiments enable procedures to be performed outside the hospital setting, such as in a doctor's office or clinic. An intrauterine access end procedure system includes a mechanical distension element, to eliminate the need for liquid distension media at pressure sufficient to create a risk of intravasation.

Abstract: Systems, methods, apparatus and devices for performing improved gynecologic and urologic procedures are disclosed. An intrauterine access and procedure system includes a laterally deflectable sheath. The various embodiments enable procedures to be performed outside the hospital setting, such as in a doctor's office or clinic.

Abstract: Systems, methods, apparatus and devices for performing improved gynecologic and urologic procedures are disclosed. Patient benefit is achieved through improved outcomes, reduced pain, especially peri-procedural pain, and reduced recovery times. The various embodiments enable procedures to be performed outside the hospital setting, such as in a doctor's office or clinic. Distension is achieved mechanically, rather than with liquid distension media, thereby eliminating the risk of intravasation.

Abstract: Disclosed herein are methods of treating a patient, comprising providing a compressible attenuation device that is moveable from a first, introduction configuration to a second, implanted configuration. The attenuation device is introduced into a treatment site. In one embodiment, the treatment site is the bladder. In another embodiment, the treatment site is the abdominal cavity. The volume of the attenuation devices changes in response to pressure changes in the treatment site and attenuates pressure changes in the bladder.

Abstract: Disclosed herein is an attenuation device comprising a flexible housing and a medium capable of transformation to inflate the housing from the first configuration to the second configuration. Also disclose herein are methods of treating a patient, comprising: providing a self-inflating expandable attenuation device, containing a medium which is transformable from a first, reduced volume to a second, expanded volume; positioning the attenuation device within the patient at a treatment site; and transforming the medium from the first volume to the second volume. In one embodiment, a self-inflating expandable attenuation device is used to treat urinary tract dysfunction. In another embodiment, a self-inflating expandable attenuation device is used to treat benign hypertrophy of the prostate.

Abstract: Disclosed herein are devices for treating symptoms of a urinary tract dysfunction having an expanded volume within the range of from about 1 cc to about 400 cc. In one embodiment, the device comprises a valve having a first membrane and a second membrane with a flow passage therebetween for filling the attenuation device. In another embodiment, the device comprises a valve for permitting the filling of the attenuation device through a filling device.

Abstract: Disclosed are pressure attenuators, for attenuating pressure changes in an anatomical structure. The attenuators are movable from a first, introduction configuration to a second, implanted configuration. When in the second, implanted configuration, the attenuator attenuates pressure spikes within the body by reversibly reducing in volume in response to the pressure spike. In one application, the attenuator is utilized to treat urinary tract dysfunctions. Deployment devices, retrieval devices, and methods are also disclosed.

Abstract: The speed command for an open-loop brushless motor speed control system is overridden whenever the speed of the motor is less than a relatively low reference speed in order to quickly accelerate the motor to a running speed, despite a relatively low speed command. In the event of a motor overcurrent condition, the override is itself overridden to protect the controller.
