The Gemini FPD is indicated for the fragmentation of urinary tract stones, i.e. renal calyceal stones, renal pelvic stones, and upper ureteral stones.

Device Description

The Gemini FPD is a modular urological work station designed for extracorporeal shock wave lithotripsy ("ESWL") and for diagnostic and therapeutic procedures usual in Urology.

The Gemini FPD is composed of the following modules:

Basic Unit with integrated X-ray C-arm and Therapy Arm for Shockwave Treatment: .
Patient Table: .
Control Desk User Interface; and .

The basic unit contains the power supplies, control unit, power electronics for motor drives, components for shockwave generation, and an integrated Therapy C-arm and an X-Ray C-Arm. The housing can be positioned with its back close to the room wall and has wide side doors for easy service.

The therapy and X-Ray C-arm house the shock wave source (*EMSE'') and the complete X-ray unit. The X-ray unit consists of the X-ray generator, the X-ray tube. the FPD image receptor module, and a high resolution camera imaging chain. This provides the imaging to perform the procedures. The C-arms allow for a wide range of movement to facilitate performing urological procedures.

The shock wave circuit supplies the shock wave energy needed for the treatment of kidney stones.

The Gemini FPD's urological patient table provides longitudinal, lateral and vertical travel range to allow easy positioning of the stone in the shock wave focus for lithotripsy and urological procedures. It is the same as in the predicate device.

The image processing system with DICOM 3 capability supports PACS connection and offers complete X-ray control and image handling.

AI/ML Overview

This document is a 510(k) summary for the Gemini FPD Lithotripter, detailing its substantial equivalence to predicate devices rather than providing a study proving its acceptance criteria.

Summary of what the document does describe regarding compliance and equivalence:

The document asserts that:

The Gemini FPD device, as well as the predicate device, complies with a list of international standards (e.g., IEC 60601-1 for electrical safety, IEC 60601-2-36 for extracorporeally induced lithotripsy, ISO 13485 for Quality Management System).
It also complies with all requirements described in FDA's Guidance for the Content of Premarket Notifications (510k's) for Extracorporeal Shock Wave Lithotripters Indicated for the Fragmentation of Kidney and Ureteral Calculi.
The Gemini FPD is substantially equivalent to its predicate devices (Dornier Gemini Lithotripter K121656 and Dornier Genesis K122768) because it has similar technological characteristics and the same intended use. The primary modification is the use of a flat panel detector for X-ray imaging, which is identical to the system used in the cleared Dornier Genesis (K122768). The shock wave source and supporting electronics are identical to the predicate Gemini device.

Substantial Equivalence

The Gemini FPD has similar technological characteristics as the predicate FDA-cleared Gemini Lithotripter (K121656), to which it is a modification. The Gemini are extracorporeal shock wave lithotripters used for fragmentation of urinary tract stones, i.e., renal calyceal stones, renal pelvic stones, and upper ureteral stones. The technology to perform this function involves use of an electromagnetic shock wave emitter ("EMSE"). In the case of the subject device and the cleared product. the identical shock wave source is used as well as all supporting electronics. The other elements of the

Gemini FPD, i.e., the patient table and the X-ray unit, are the same as that of the Gemini (K121656). They perform the same function and operate in the same manner during the procedures involved in the fragmenting of urological stones.

The subject and predicate devices utilize fluoroscopic X-ray systems. Specifically, the Genini uses a solid state Image Intensifier to capture the X-ray image while the Gemini FPD uses a flat panel detector to receive X-ray radiation beams in order to produce anatomical images of adequate resolution for diagnostic/treatment purposes. The flat panel detector used in the subject device is identical to the system used in the cleared Dornier Genesis (K122768). The X-ray source for the Gemini FPD is unchanged from the cleared predicate device.

From a clinical perspective and comparing design specifications, the Gemini FPD and the predicate devices are substantially equivalent and have the same intended use.

Dornier MedTech America, Inc. believes the minor differences do not raise any concerns regarding the overall safety or effectiveness. Thus, the Gemini FPD is substantially equivalent to its predicate devices.

Regulation Number and Section

§ 876.5990 Extracorporeal shock wave lithotripter.

(a)
Identification. An extracorporeal shock wave lithotripter is a device that focuses ultrasonic shock waves into the body to noninvasively fragment urinary calculi within the kidney or ureter. The primary components of the device are a shock wave generator, high voltage generator, control console, imaging/localization system, and patient table. Prior to treatment, the urinary stone is targeted using either an integral or stand-alone localization/imaging system. Shock waves are typically generated using electrostatic spark discharge (spark gap), electromagnetically repelled membranes, or piezoelectric crystal arrays, and focused onto the stone with either a specially designed reflector, dish, or acoustic lens. The shock waves are created under water within the shock wave generator, and are transferred to the patient's body using an appropriate acoustic interface. After the stone has been fragmented by the focused shock waves, the fragments pass out of the body with the patient's urine.(b)
Classification. Class II (special controls) (FDA guidance document: “Guidance for the Content of Premarket Notifications (510(k)'s) for Extracorporeal Shock Wave Lithotripters Indicated for the Fragmentation of Kidney and Ureteral Calculi.”)
