Software version 3.35 of the Venclose digiRF Generator incorporates a catheter verification feature specifically designed to detect internal wiring anomalies in Venclose EVSRF Ablation Catheters prior to clinical use. This automated diagnostic check is executed immediately upon catheter connection to the generator, occurring before the procedure interface becomes accessible. When a catheter fails this verification process, the generator displays a Red X indicator on the screen without accompanying error codes, effectively disabling catheter functionality. However, BD has determined that software version 3.35 generates false positive failures due to temperature-dependent verification parameters, incorrectly flagging properly functioning Venclose EVSRF Ablation Catheters as defective when the catheter temperature is not at steady state during the check initiation.

Atherectomy Catheter eIFU updated to clarify and emphasize procedural steps intended to reduce the likelihood of catheter breakage events. Catheter has an outer cylinder connected to a rotating helix, which could fracture and/or break, which would require retrieval, and helix facture/break could cause vessel injury and lead to severe bleeding.

Disposable biopsy instruments were potentially manufactured missing the backend notch retention feature on the needle that results in inadequate securing of the needle inside the device, which could lead to needle detachment and misplacement, which could lead to tissue damage and bleeding.

The Venclose" RF Ablation Catheters may have been manufactured with internal wiring error. The red and yellow signal wires were soldered on swapped ports of the catheter PCB. This error in wire configuration would lead to power being applied through the proximal 3/4th of the heating coil, bypassing the thermocouple, which will then cause the generator to overdrive the catheter in an attempt to reach desired temperature set point. The wire attachment error causes the device to reach temperatures exceeding the levels intended for therapeutic efficacy, while the console is falsely indicating that temperature has not yet been reached, thus increasing the risk of harm due to excessive temperature.

Due to possible packaging damage (indentations/cuts) cause by manufacturing process. As a result of the packaging damage, may cause the sterile barrier to be compromised.

Due to guidewires being manufactured incorrectly with the guidewires being mis-assembled within the hoop such that the proximal (stiff) end of the guidewire is located at the distal end of the hoop. Injury could occur if the user attempts to insert the proximal end into the patient.

Recanalization systems may be in a manufacturing mode that allows the system to continuously run without the typical 30 second pauses, and 4-minute warning/5-minute restart required messages to indicate the ten-minute maximum catheter use time has been exceeded, which may increase the risk of the device overheating or breaking.

The internal diameter of the coaxial cannula may be smaller or larger than the external diameter of the biopsy needle, and the length of the cannula may exceed the stated length on the label. As a result, the biopsy needle may not fit properly into the coaxial cannula, preventing access to the target tissue, which could lead to tissue injury, longer and repeat procedures.

Diameter mismatch between coaxial and biopsy needle (cutting cannula) in disposable core biopsy instrument kits, where the coaxial cannula inner diameter prohibits the biopsy needle (cutting cannula) from properly fitting into the coaxial cannula and accessing target tissue, which may lead to repeated procedure, and procedural complications, such as pain/discomfort, pneumothorax, and bleeding.

Coaxial cannula internal diameter and length of biopsy instruments exceed the external diameter and length of the biopsy needle, prohibiting the biopsy needle from properly fitting into the coaxial cannula and accessing the target tissue, which could lead to procedure delay, and insufficient sample acquisition requiring a repeat procedure.

The external diameter of the biopsy instrument is larger than the internal diameter of the coaxial needle, which could lead to: 1) Procedural delay, 2) Requirement of an additional device, 3), Needle tip breakage, if used despite incompatibility.
