The Patient Return Electrode is indicated for use only with Target Therapeutics GDC System as the patient return electrode.
Device Story
Single-use, non-sterile patient return electrode (PRE); applied to patient deltoid skin; includes prep pad for skin exfoliation. Replaces hypodermic needle as return electrode for Target Therapeutics GDC system. Used in clinical settings by physicians. Enhances patient comfort; no impact on GDC system safety or efficacy. Bench testing (tensile, impedance), animal studies, and biocompatibility testing confirm performance.
Clinical Evidence
Bench testing (tensile and impedance), animal studies, and biocompatibility testing performed. No human clinical trial data reported.
Technological Characteristics
Single-use, non-sterile disposable electrode. Applied to skin via adhesive. Includes skin exfoliation prep pad. Passive electrical return component.
Indications for Use
Indicated for use as a patient return electrode exclusively with the Target Therapeutics GDC System.
Regulatory Classification
Identification
A neurovascular embolization device is an intravascular implant intended to permanently occlude blood flow to cerebral aneurysms and cerebral ateriovenous malformations. This does not include cyanoacrylates and other embolic agents, which act by polymerization or precipitation. Embolization devices used in other vascular applications are also not included in this classification, see § 870.3300.
Special Controls
*Classification.* Class II (special controls.) The special control for this device is the FDA guidance document entitled “Class II Special Controls Guidance Document: Vascular and Neurovascular Embolization Devices.” For availability of this guidance document, see § 882.1(e).

## DEVICE NAME:
Patient Return Electrode (PRE); Class II
## DEVICE DESCRIPTION:
Target Therapeutics' Patient Return Electrode (PRE) is a single use, disposable, non-sterile electrode. The PRE is intended to be used as an alternative patient return electrode for Target Therapeutics GDC system (K951256 & K960705). A hypodermic needle is currently used as the patient return electrode. The PRE is applied to the skin on the patient's upper arm (deltoid). The PRE is being made available for patient comfort and has no effect on the safety or efficacy of the GDC system as functional testing indicates.
A small Prep pad is included with the PRE to exfoliate the skin prior to applying the PRE.
## INDICATIONS FOR USE:
The Patient Return Electrode is indicated for use only with Target Therapeutics GDC System as the patient return electrode.

# TESTING in SUPPORT of SUBSTANTIAL EQUIVALENCE DETERMINATION:
The results of bench testing (Tensile Test, Impedance Test), animal studies, and biocompatibility testing support the substantial equivalence claims of the PRE for its intended use. Results of the bench testing, animal studies, and biocompatibility testing in conjunction with the substantial equivalence claims as outlined in the premarket notification, effectively demonstrate the PRE is substantially equivalent to the predicate devices.
