The reported event was confirmed.Evaluation of the sample noted that the sample was received in poor condition.The wire was tangled and the proximal end of the wire was unraveled to approximately the midpoint of the wire.The teflon applied along this length of unraveled area was flaking and hanging loose from the coils of the wire.The device history record was reviewed and found nothing that could have caused or contributed to the reported event.The instructions for use were found adequate and state the following: ¿english bard® guidewires information for use description: guidewires are used to provide access and facilitate passage of endourological instrumentation during urological procedures.They are offered in many different configurations that include: sizes (lengths and diameters), tip designs, coatings (hydrophilic and ptfe) and stiffness.The bard® u-nite¿ guidewire has a hydrophilic-coated tip and ptfe coated body.The bard® nicore¿ wire has a nitinol core and a hydrophilic coating.The bard® hydroglide¿ stainless steel guidewires are available with a hydrophilic coating.The bard® stainless steel guidewires are available with and without ptfe and are available in fixed and movable core.Indications: bard® guidewires are indicated to provide transurethral and/or percutaneous access into the bladder, ureter or renal pelvis.Contraindications: there are no known contraindications warning: inspect all guidewires for damage prior to use.Bending or kinking during or prior to placement could damage the guidewire.Do not attempt to use the guidewire if it has been damaged.Use of a damaged wire may result in damage to the urinary tract.Do not reshape the guidewire by any means.Attempting to reshape the guidewire may cause damage resulting in release of fragments into the urinary tract.Failure to exercise proper caution may result in damage to the urinary tract.Do not manipulate or remove the guidewire through a metal cannula or needle.This may result in destruction/ separation of the outer jacket of the wire requiring retrieval.Use extreme caution when using a laser, making sure to avoid contact with the wire.Direct contact could result in damage / breakage to the wire.Attention should be paid to guidewire movement in the urinary tract.Before a guidewire is moved or torqued, tip movement should be examined under direct vision or fluoroscopy.Do not advance or withdraw a guidewire when resistance is encountered as perforation could occur.Sufficient guidewire length must remain exposed to maintain a firm grip on guidewire at all times.Failure to comply with the warnings could result in damage to the guidewire to include, but not limited to: wire breakage, abrasion of the coating, release of guidewire fragments into the urinary system, all of which might require intervention.This is a single use device.Do not resterilize any portion of this device.Reuse and/or repackaging may create a risk of patient or user infection, compromise the structural integrity and/or essential material and design characteristics of device, which may lead to device failure, and/or lead to injury, illness or death of the patient.The uninterrupted actual use for this device, including immediate replacement with the same or an identical device, is intended to be 30 days or less.Precautions: should be used only by physicians thoroughly trained in endourological guidewire techniques.Do not use dry gauze to manipulate the guidewire as this can damage the surface coating and make the wire tacky.Caution: federal (u.S.A.) law restricts this device to sale by or on the order of a physician.Potential complications: complications that may result from the use of a guidewire in a urological procedure incude, but are not limited to: ¿ perforation ¿ acute or delayed bleeding ¿ tissue trauma ¿ edema direction for use: the physician should select the proper size and length of the guidewire for the procedure being performed.1.The guidewire is packaged in a protective coil.For hydrophilic coating wires: hydrophilic coated guidewires require activation of their coating.Prior to removing the guidewire from the protective coil, inject sterile saline through the port to activate the lubricious coating.Remove the guidewire from the protective coil and carefully inspect the coil for separation, bends, kinks or a damaged tip.For ptfe wires: remove the guidewire from the protective coil and carefully inspect the coil for separation, bends, kinks or damaged tip.2.Introduce the guidewire, flexible end first, into the working channel of the endoscopes or percutaneously into the urinary tract.3.Advance the guidewire slowly into the desired position.Continuously confirm guidewire position either visually or under fluoroscopy.4.Carefully withdraw the guidewire taking care not to kink.Note: after use, this product may be a potential biohazard.Handle and dispose of in accordance with accepted medical practice and with applicable laws and regulations.References: 1.Clayman, r.V., castaneda-zuniga, w., techniques in endourology: a guide to the percutaneous removal ofrenal and ureteral calculi, copyright 1984 by ralph
