Additional Manufacturer Narrative
The customer's reported complaint description of sheath tubing detached cannot be confirmed.No sheath complaint sample was returned for evaluation.Without receiving product for evaluation, we are unable to definitively determine a root cause for this incident.A potential root cause for this type of sheath tubing failure mode is handling damage during use, i.E.Sheath tubing nicked by scalpel and then pulled to failure.Dhr review of the packaging/introducer lots could not be performed since there was no reported lot number.Dhr review of shr lots could not be performed since end user facility is unknown.A review of similar reported complaints against the coaxial sheath has shown a consistent detachment of the sheath tubing at least one (1) cm distal from the sheath hub junction, i.E.Not a failure at the hub junction.The failure of this sheath tubing failure mode generally indicates a slice in the tubing from a sharp object with separation location of the tubing being stretched, indicating a tensile failure of the tubing.The mini stick max is a coaxial micro-introducer kit used for initial access into the vasculature.Once the coaxial sheath is in place an 0.035/0.038" procedure (j) guidewire is inserted into the vasculature.Depending on the purpose of the patient procedure the sheath may be upsized (e.G.7f, then 10f, then 14f, etc.) to accommodate larger french size catheters/devices.After inserting the 0.035" guidewire into the coaxial sheath but prior to removal of the coaxial sheath the physician may choose to nick the skin with a scalpel at the insertion site in anticipation of the insertion of the larger sheath device.This technique may cut the coaxial sheath tubing such that the tubing is pulled to failure during removal of the coaxial sheath.If a nick of the skin is required then performing this after the coaxial sheath is removed (i.E.Nick skin with just 0.035" guidewire sticking out of insertion site) would prevent damage to sheath tubing and potential tubing tensile failure.Labeling review: directions for use (dfu) that is provided with this device contains the following statements.The failure mode of device determined if device was used in a manner inconsistent with labeling.Intended use/ indications for use the coaxial micro introducer kit is used for the percutaneous introduction of a guidewire into the vascular system.Adverse events; guidewire shearing, fracture or embolization.Operational instructions: 1.Prior to insertion, flush all components with saline or heparinized/saline.2.Gain percutaneous access with the 21 g (0.9 mm) vascular introducer needle.3.Advance the 0.018 inch (0.46 mm) guidewire through the needle.Caution: the guidewire should not be withdrawn through the introducer needle.If the guidewire must be withdrawn while still inside the needle, simultaneously remove both the needle and the wire as a unit to prevent the needle from damaging the guidewire.4.Withdraw the introducer needle, leaving the 0.018 inch (0.46 mm) guidewire in place.5.Advance the coaxial assembly over the 0.018 inch (0.46 mm) guidewire.6.Simultaneously remove the dilator and 0.018 inch (0.46 mm) guidewire, while holding the sheath portion of the assembly in place.7.Advance a 0.035 inch (0.89 mm) or 0.038 inch (0.97 mm) guidewire into the sheath.8.Remove the sheath, leaving the 0.035 inch (0.89 mm) or 0.038 inch (0.97 mm) wire.A review of the angiodynamics complaint system noted no adverse trends for this complaint type and product family.This type of complaint will continue to be monitored for trends.Reference (b)(4).
Event or Problem Description
Angiodynamics received notification of an event from the fda regarding a mini stick max 5f x 10 cm stiff.018 ni/tu echo 2.75".A patient with a diagnosis of atherosclerosis of the left lower extremity with first toe ulceration was admitted for a left transpopliteal superfical femoral artery intervention.A coaxial microintroducer (mini stick max) was used in the procedure.During the procedure, a portion (7.62cm) of the catheter [sheath tubing] broke off and became lodged in the tissue surrounding the artery.The object could not be removed without a surgical procedure.The patient elected to not have the object removed.
