Abstract: Hysteroscopic system includes a hysteroscope having a main body coupled to an extension portion. The extension portion may be a shaft configured to extend transcervically to a patient's uterine cavity. First, second, and third channels extend from the main body to a distal end of the extension portion. A fluid source is coupleable to a proximal end of the first channel, and a pressure sensor is coupleable to a proximal end of the second channel. A tissue resecting probe is configured for introduction through the third channel. At least one resistance feature is included which is configured to provide a selected level of resistance to axial sliding of the probe through the third channel while permitting rotation of the probe within the third channel.

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: An endoscope includes a shaft assembly having proximal and distal ends and a longitudinal axis therebetween. A handle is coupled to the proximal end of the shaft assembly, and an elastomeric body housing an image sensor and at least one LED is comprises a distal end of the shaft. The elastomeric body is deformable between a repose straight insertion profile and a deflected offset profile by the insertion of a tool shaft through the shaft assembly and an expandable-collapsible working channel in the elastomeric body. The viewing angle of the image sensor is moved from a first selected angle to a second selected angle when the elastomeric body is actuated from the repose profile to the deflected offset profile.

Abstract: Systems and methods for endometrial ablation. The systems include a handle and elongated introducer sleeve extending to an expandable working end having a fluid-tight interior chamber. A thin dielectric wall surrounds at least a portion of the interior chamber and has an external surface for contacting endometrial tissue. The thin dielectric wall surrounds a collapsible-expandable frame and receives an electrically non-conductive gas. First and second polarity electrodes are exposed to the interior and exterior of the chamber, respectively. A radiofrequency power source operatively connects to the electrode arrangement to apply a radiofrequency voltage across the first and second electrodes, wherein the voltage is sufficient to initiate ionization of the neutral gas into a conductive plasma within the interior chamber, and to capacitively couple the current in the plasma across the thin dielectric wall to ablate endometrial tissue engaged by the external surface of the dielectric structure.

Abstract: Methods, systems and devices for evaluating the integrity of a uterine cavity. A method comprises introducing transcervically a probe into a patient's uterine cavity, providing a flow of a fluid (e.g., CO2) through the probe into the uterine cavity and monitoring the rate of the flow to characterize the uterine cavity as perforated or non-perforated based on a change in the flow rate.

Abstract: Tissue is treated using a radiofrequency power supply connected to an applicator having a chamber filled with an electrically non-conductive gas surrounded by a thin dielectric wall. A radiofrequency voltage is applied at a level sufficient to ionize the gas into a plasma and to capacitively couple the ionized plasma with the tissue to deliver radiofrequency current to ablate or otherwise treat the tissue.

Abstract: A system for treating uterine tissue having a seal assembly configured for positioning in a patient's cervical canal and uterine cavity; an expandable distal balloon portion; an expandable elongate medial balloon portion configured for movement between a first transversely expanded shape for engaging a cervical canal and a second transversely non-expanded shape for trans-cervical insertion; and a fluid source in communication with distal balloon portion and medial balloon portion for expansion of said balloon portions.

Abstract: Systems and devices for resecting and removing tissue or organs from the interior of a patient's body, in a minimally invasive laparoscopic procedure while preventing any dispersion of potentially malignant tissue during the resection process.

Abstract: The present invention relates to medical devices and methods for treating and occluding a female patient's fallopian tubes to provide birth control or sterilization, where such birth control/sterilization can be short term, long term, or permanent.

Abstract: Robotic surgical systems configured to control the movement and actuation of a single robotic arm, and the movement and actuation of multiple tools carried at a distal end of the robotic arm.

Abstract: The tissue cutting device comprises an elongated assembly including both an outer sleeve and an inner sleeve. The outer sleeve has a tissue-receiving window, and the inner sleeve has a distal end which cuts tissue as the inner sleeve is advanced past the window. The tissue is received into a lumen of the inner sleeve, and the inner sleeve lumen is typically enlarged in a proximal direction to reduce the tendency of resected tissue to lodge therein. The tissue displacement member is optionally provided at a distal end of the outer sleeve to further aid in dislodging tissue which becomes captured in a distal end of the inner sleeve of the lumen.
