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: Systems and methods for treating vertebral compression fractures are discussed. In an embodiment, a method includes mixing bone cement precursors thereby causing a first chemical curing reaction characterized by a first time-viscosity profile, controllably applying energy to the bone cement from an external source to modify the first time-viscosity profile to a second time-viscosity profile, and injecting the cement into bone at a substantially constant viscosity greater than about 1000 Pa·s to greater than about 5000 Pa·s over an extended working time. In another embodiment, a bone cement injector system is provided that includes a first handle component that is detachably coupled to a second sleeve component having a distal end for positioning in bone and a flow channel extending through the first and second components. The system includes first and second thermal energy emitters for delivering energy to bone cement flows in a flow channel portion in the first and second components, respectively.

Abstract: An endoscope includes a shaft having proximal and distal ends and a longitudinal axis therebetween. A handle is coupled to the proximal end of the shaft, and an image sensor is carried on the distal end of the shaft. A channel extends through at least a distal shaft portion and has a channel diameter, and a section of the channel is re-configurable between a constricted shape and a non-constricted shape to accommodate tools introduced therethrough. The combined diagonal dimension and channel diameter is usually greater than the outer shaft diameter. The image sensor may be connected to a connector on the housing by a first slack flex circuit and a lights source on the shaft may be connected to a connector on the housing by a second slack flex circuit.

Abstract: Tissue may be cut and extracted from an interior location in a patient's body using a probe or tool which both effects cutting and causes vaporization of a liquid or other fluid to propel the cut tissue through an extraction lumen of the cutting device. The cutting may be achieved using an electrosurgical electrode assembly, including a first electrode on a cutting member and a second electrode within a cutting probe or tool.

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: 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.
