A simple surgical drape system of generally flat shape for male urology procedures that provides full isolation of top versus bottom surface by a sealing fenestration surrounding the meatus area. It is achieved by manually forming the flat drape to a tent-like shape around the penis with a fenestration aperture smaller than glans diameter, supported by and sealing to the glans tip, and then attaching a penile clamp to hold the drape. This allows a simplified safer antibacterial preparation and less chance of infection complications. The sealed design permits better management of urology liquids, and can use absorption pad on drape top side. The drape wrinkles act as a penile position stabilizer, reducing need for extended use of the one operator hand for penile support. Drape is removable with catheter in place.

A surgical instrument includes a working sheath and an obturator. A method is also described for facilitating endoscopic examination and surgical procedures using such an instrument. The sheath is an elongated self-supporting tube with a lumen of sufficient size to accommodate other-surgical instruments. During use, the instrument is placed in the body percutaneously or through a body passage with the removable obturator located in the lumen to facilitate insertion of the sheath into the body. Once inserted, the obturator can be removed. The sheath is held in place by an inflatable bulb provided on the distal end of the sheath while the operation is being completed. A peripheral duct is also preferably provided for introducing anesthetic or lubricant during insertion. Any of various instruments selected by the surgeon, including instruments that are larger than the lumen of the sheath, can be inserted and removed by being passed into the body through the lumen of the sheath while the sheath remains in a substantially fixed position. The sheath thus acts as an artificial protective lining for the body opening through which it is passed, e. g.

A flexible medical intubation instrument provided for placement into an animal or human patient comprises a catheter with at least a pair of longitudinally extending lumens or channels including a sensor and/or actuator channel and a working channel. In the sensor/actuator channel is provided a fixed or slideably removable sensor cable having a sensor for sensing a characteristic or condition including any of the following: a visual sensor for optical viewing, a chemical sensor, a pH sensor, a pressure sensor, an infection sensor, an audio sensor, or a temperature sensor. The sensors are coupled by the sensor/actuator cable through light transmission, electric current, or radio transmission to a viewing instrument or other output device such as a meter or video screen for displaying the condition that is sensed within the body of the patient while the flexibility of the composite structure comprising the catheter and cable enable the entire instrument to flex laterally as it moves through curved passages or around obstructions during insertion or removal. While making observations through the sensor channel, the working channel simultaneously functions as a drain or an irrigation duct, a feeding tube, or to provide a passage for the insertion of one or a succession of surgical devices such that the catheter serves as a protective artificial tract or liner as surgical devices are inserted and removed through it in succession so as to minimize tissue trauma, infection, and pain experienced by the patient. The instrument can be used in urology, as well as a visually directed nasogastric tube, as a visually directed external gastrostomy tube, or as a visually directed internal gastric tube or percutaneous endoscopic gastrostomy tube and in other applications.

A flexible direct vision fiberoptical viewing cable is placed within a urinary catheter with its tip located at a distal end of the catheter such that the surfaces of the distal end of both the viewing cable and the catheter are aligned so as to fit together in such a way as to form a composite smoothly curved surface to facilitate negotiating obstructions. The cable is maintained in this position within the catheter with the surfaces that comprise the tip of the instrument, maintained in alignment. The urethra is then viewed therethrough during all or part of the insertion procedure for observing and identifying obstructions that may be present and thereafter the fiberoptic cable is withdrawn while allowing the catheter to remain in place within the urethra. Another form of instrument includes a working sheath and an obturator. A method is also described for facilitating endoscopic examination and surgical procedures through the sheath.

A flexible medical intubation instrument provided for placement into an animal or human patient comprises a catheter with at least one longitudinally extending lumen or channel. A fixed or slideably removable sensor cable is at least partially contained within the channel, having a sensor for sensing a characteristic or condition. While enabling observations through the sensor channel, the working channel may simultaneously function as a drain or an irrigation duct, a feeding tube, or to provide a passage for the insertion of one or a succession of surgical devices such that the catheter serves as a protective artificial tract or liner as surgical devices are inserted and removed through it in succession so as to minimize tissue trauma.

A squeeze-to-set medical clamp having a first unset position and a second set position is disclosed. The clamp generally includes a primary arm, a secondary arm, a resilient arm connector, a top jaw, a lower jaw, and a deflector. The clamp is generally configured to receive a portion of the human or animal anatomy between the top jaw and the lower jaw when the clamp is in the second set position. In order to transition the clamp from the first unset position to the second set position a force is applied to the primary and secondary arms causing at least one of the top and lower jaws to contact and translate along the deflector until the top jaw and lower jaw are deflected. Next, the force is removed from the primary and secondary arms causing the resilient arm connector to bias the top and lower jaws toward one another.
