Abstract: A medical introducer includes an elongated tubular member having a proximal end, a distal portion, and a central lumen extending from the proximal end to a distal port in the distal portion. A frame structure is coupled to the distal portion of the elongated tubular member, where frame structure supports the distal portion of the elongated tubular member in a tapered shape and alternatively in a non-tapered shape. The elongated tubular member may include a rigid outer tube and a rigid inner tube carried in an interior lumen of the outer tube. The distal portion is typically a reinforced elastomeric tubular extension of the outer tube, and the reinforced elastomeric tubular extension may have a conical shape.

Abstract: Apparatus for performing electrosurgical tissue resections, such as transurethral resection of the include motor-driven cutters which drive both a shaft of the cutter and a cutter electrode, either or selectively. The systems often include controllers which coordinate movements of the shaft, electrodes, and other external components. The apparatus may include integrated imaging and light illumination systems. The apparatus may include integrated tissue filter and collection traps.

Abstract: A tissue resecting or other medical device includes a handle coupled to an elongated shaft. A radiofrequency (RF) electrode is carried at a distal end of the elongated shaft, and the electrode is moveable across a window in a sleeve or other component of the shaft. The shaft has an interior channel connectable to a negative pressure source to remove debris from the channel. A motor is carried by the handle and operatively coupled to the electrode for moving the electrode relative to the window. An electronic image sensor and lens are disposed at a distal end of the shaft, and a plurality of conductors may extend through the shaft to the image sensor. The image sensor, lens and sensor conductors are disposed within a first tubular member, and an LED or other light source is also positioned at a distal end of the shaft with LED conductors or leads extending through a second tubular member of the shaft to the LED.

Abstract: An imaging and resecting device includes a handle coupled to an elongated shaft extending about a longitudinal axis and having an interior passageway extending therethrough. A resecting component shaft extends through the interior passageway to a working end carrying an RF electrode, and a sensor sleeve at having an insulative layer extends through the interior passageway and is coupled to a distal image sensor formed from an sensor chip and a lens having an optical axis and a field of view. The image sensor is sized to fit within an open distal end of the interior passageway, and at least one co-axial sensor cable carried in an interior lumen of the sensor sleeve, each sensor cable having a shielding layer and coupled to the image sensor. The sensor sleeve is configured to shield the image sensor and each sensor cable from electrical interference caused by the RF electrode during use.

Abstract: A surgical system for treating targeted tissue in a fluid-filled working space includes a probe having an elongated shaft extending from a proximal end to a working end. A tissue-receiving window formed in the working end opens to a passageway in the elongated shaft, and a motor moves an electrode across the tissue-receiving window to resect tissue. A radiofrequency (RF) current source is coupled to the electrode, and a controller operatively connected to the motor and the RF source. In some instances, the controller actuates movement of the electrode in response to electrode contact with the targeted tissue. In some instances, the controller actuates movement of the electrode in a single stroke to perform biopsy.

Abstract: Systems and methods for wireless energy transfer are described. A transmitter unit has a transmitter resonator with a coil that is coupled to a power supply to wirelessly transmit power to a receiver unit. A receiver unit has a receiver resonator with a coil coupled to a device load. The receiver unit can include a ferrite enclosure to prevent transmission of magnetic flux into electronics of the receiver unit, and can include ferrite fins to increase a coupling between the transmitter resonator and the receiver resonator.
