It was reported that when asked why they were dissatisfied with the overall performance of the stone basket product, the respondent said it was difficult to advance both a laser fiber and the basket simultaneously through the working channel of the ureteroscope due to the small blue bulb at the end of the basket.Then, when the respondent was asked to describe the unexpected challenges faced with using the product, they said "as i had indicated previously, it was difficult to pass both the basket and a laser fiber simultaneously through the ureteroscope working channel due to the blue blub at the tip of the basket.".

The reported event was inconclusive as no sample was returned for evaluation.A potential failure mode could be ¿drive cable not smooth¿ with a potential root cause of ¿drive cable geometry¿.The lot number is unknown; therefore, the device history record could not be reviewed.The instructions for use were found adequate and state the following: "description: the bard® skylitetm tipless nitinol stone basket consists of a handle to open, close and rotate the basket, a flexible polyimide shaft and a 4-wire nitinol stone basket.The package includes one (1) basket and one (1) introducer.Indications for use: this device is intended for use in endoscopic removal of ureteral and renal stones.Contraindications: none known warnings: ¿ some objects may be too large to be removed endoscopically using a retrieval device.The use of fluoroscopy and/or x-ray to determine the size of the object is recommended.Do not use the bard® skylitetm tipless nitinol stone basket if the object is too large to be removed endoscopically, as it may result in patient injury and pain.¿ 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 the device, which may lead to device failure, and/or may lead to injury, illness or death of a patient.¿ do not attempt to repair, reassemble, or alter the device in any way.¿ after use, this product will be a potential biohazard.Handle and dispose of in accordance with accepted medical practices and with applicable laws and regulations.Follow your institutional guidelines.Caution: objects that are too large to be removed through the scope channel will require the scope and basket to be removed simultaneously from the urinary tract.If resistance is encountered during advancement or withdrawal of the device, stop and determine the source of resistance, as continued resistance may damage the device and could result in patient injury.Take action to alleviate the resistance.Precautions: before using, inspect for any breach of packaging to ensure sterility of product.Do not use if breach in sterile barrier is obvious or suspected.Do not allow the device to come in contact with any electrified instruments or laser.Kinks in the sheath will hinder the mechanical operation of the basket, may affect insertion or withdrawal of the basket and has the potential to damage the endoscope¿s instrument channel.Do not allow the device to be directly fired upon by any lithotripsy devices.To do so may result in damage to the device and could result in patient injury.Potential complications that may result from the use of a basket in an endoscopic urological procedure include, but are not limited to: ¿ perforation ¿ evulsion ¿ edema ¿ entrapment ¿ laceration ¿ basket inversion ¿ hemorrhage ¿ inability to disengage from irretrievable object directions for use: only physicians trained in stone manipulation should perform this procedure.A variety of techniques may be employed; however the physician should use the technique most appropriate for the individual patient¿s situation.Insertion 1.Inspect the device prior to use and during the procedure for integrity and function.2.Make sure the basket is closed by retracting (pulling back) the basket tip into the sheath with the thumb slide as shown in figure b.3.With the basket closed, and using the optional introducer provided, carefully advance the distal portion of the closed device through the endoscope until it emerges out of the end of the endoscope.Capture and removal 1.Under direct vision or fluoroscopic guidance, slowly advance the basket tip past the object.2.Open the basket by pushing the thumb slide forward.(refer to figure b).3.Pull the basket backward toward the object while slowly rotating the basket as necessary.4.Once the object has been captured, partially close the basket to secure the object for removal by carefully pulling the thumb slide back.(refer to figure b).5.Slowly remove the basket and stone from the urinary tract.6.If the object is too large, you may need to simultaneously withdraw the basket and the ureteroscope from the urinary system.Directions for disassembly if handle disassembly is desired or required: 1.Squeeze bottom handle half at indicated points and pull down to remove handle bottom.2.Loosen thumbscrew until basket drive wire moves freely.3.Slide sheath and handle assembly over and away from drive wire." h11:section a through f - the information provided by bd represents all of the known information at this time.Despite good faith efforts to obtain additional information, the complainant / reporter was unable or unwilling to provide any further patient, product, or procedural details to bd.H3 other text : the device was not returned.
