The Disposable Ureteral Access Sheath is used to establish a continuous conduit during urological endoscopic procedures facilitating the in and out passage of endoscopes and other instruments into the urinary tract.

The proposed device, Disposable Ureteral Access Sheath is used to establish a continuous conduit during urological endoscopic procedures facilitating the in and out passage of endoscopes and other instruments into the urinary tract. This device is divided into five types: - Z type Straight joint access sheath - Y type negative suction Y joint access sheath - W type negative suction W joint access sheath - T type Straight joint access sheath - C type negative suction W joint access sheath This product consists of access sheath and dilator tube. The access sheath tube consists of access sheath tube body and access sheath joint. The surface of access sheath tube is coated with polyvidone (PVP). The dilator tube consists of dilator tube body and dilator tube connector. The access sheath tube body is made from nylon (PA), stainless steel and polytetrafluoroethylene (PTFE). The access sheath joint is made from polycarbonate (PC), acrylonitrile-butadiene-styrene copolymer (ABS) and silicone. The dilator tube body and dilator tube connector are made from PE. The proposed devices are sterilized by Ethylene Oxide Gas to achieve a SAL of 10-6 and supplied sterility maintenance package which could maintain the sterility of the device during the shelf life of 3 years.

The Navigator HD Ureteral Access Sheath is indicated for use in endoscopic procedures to facilitate the passage of endoscopes, urological instruments and for the injection of fluids into the urinary tract.

Navigator™ HD Ureteral Access Sheath Set consists of a semi-rigid outer sheath and a semi-rigid inner dilator with interlocking hub. The set permits utilization of a guidewire to assist in device placement. Sheath: The Navigator™ HD Sheath has a sheath hub which is over-molded onto the sheath shaft has three layers: Outer Pebax layer, Reinforced stainless steel coil enhancing torqueability and maneuverability, Inner PTFE liner. The sheath outer layer contains Barium Sulphate as a radiopacifier. In addition to the stainlesssteel coil, a radiopaque marker band is sandwiched between the Pebax and PTFE layers. The radiopaque marker band is located at the sheath tip and, along with the radiopacifier added to the sheath outer layer, enhances fluoroscopic visualization of sheath placement during the procedure. A hydrophilic coating is applied to the entire length of the shaft to reduce friction and facilitate placement of the device. Dilator: The Navigator™ HD dilator has a hub with a standard luer lock at the proximal end. The tab on the dilator hub allows it to lock into the sheath hub. The dilator shaft is made of extruded tube Pellethane to allow for dimensional stability, low moisture absorption, and chemical resistance. The dilator tip is made of a softer grade of Pellethane to improve tip flexibility to assist in atraumatic placement. Both the dilator shaft and tip contain Barium Sulfate as a radiopacifier, enhancing visualization under fluoroscopy during the procedure. A hydrophilic coating is applied to the entire length of the dilator to reduce friction and facilitate placement of the device, either when assembled with the sheath or when used separately as a dilatation device.

The Dornier Hoover Negative Pressure Access Sheath is used to establish a conduit during endoscopic urological procedures facilitating the passage of endoscopes and other instruments into the urinary tract. It is designed to establish a conduit for the treatment of urinary stones or other urinary diseases during the endoscopic procedures.

The Dornier Hoover Negative Pressure Access Sheath is designed to establish a conduit for the treatment of urinary stones or other urinary diseases during the endoscopic procedures. It is for the passage of endoscopes and other urological devices for Ureteroscopy and used for the treatment of stones and for the removal of foreign bodies in the urinary tract. The packaged product includes a Hydrophilic-coated Dilator with a locking mechanism and a Hydrophilic- coated guide sheath with joint. The guide sheath is fitted with a Y connector on the Y connector is bifurcated straight tube and oblique tube. One segment of the Y connector is straight and is contiguous with the sheath. The other is constructed in an oblique angle with a longitudinal pressure control vent. The oblique tube is to be connected to a negative pressure aspirator with clear tube or alternatively, connected to a specimen collector then onto a negative pressure aspirator, then to collect stones or foreign bodies during the endoscopic procedure. A dilator is included for the insertion of the dilator is radiopaque and is fitted with a hand buckle on the proximal end. The dilator can be locked to the proximal end of the straight tube using a locking mechanism. The Dornier Hoover Neqative Pressure Access Sheath is reinforced with a stainless-steel coil, constructed of a medical grade thermoplastic elastomer. All colorants used are compliant with FDA standards. The device is offered of inner diameter in French size 10Fr, 12Fr and length 40cm, 50cm. The device is supplied sterile and intended for single use only. The Dornier Hoover Neqative Pressure Access Sheath has six different models. The structural composition and materials of the different models are identical. The only difference is in dimension including inner diameter, and length.

The ReTrace Ureteral Access Sheath is a sterile, single use device that is inserted over a guidewire into the upper or lower urinary tract of patients requiring ureteroscopic procedure sin a hospital environment. The ReTrace Ureteral Access Sheath consists of: - Reinforced tube/sheath - Introducer/dilator - Connector - Clip The reinforced polymeric introducer sheath includes a hydrophilic coating on the exterior and a lubricious inner surface. The sheath is reinforced to provide kink resistance. The distal tip of the sheath is fitted with a radiopaque ring. A white connector is fitted on the proximal end of the sheath and an orange connector is on the proximal end of the introducer to allow the two components to be attached. The dilator is fitted with a Luer connector on the proximal end and has a hydrophilic coating on the distal end. A guidewire entry and exit eye and exit holes for fluid delivery are located at the distal end of the introducer. The dilator protrudes out the distal end and allows for a gradual enlargement of the passage if needed and improves trackability along the guidewire. Once in the desired location, the dilator is removed to establish a hollow conduit for insertion of endoscopes and other instruments into and out of the urinary tract. The ReTrace Ureteral Access Sheaths are available in two diameters 10/12 Fr and 12/14 Fr. Lengths range between 28 and 55 cm. This submission is for modifications to device materials, labeling, packaging, and connector design.

This product is intended to be used in combination with an endoscope to assist endoscopic insertion into the body. Never use this product for any other purpose.
