Intended Use
The LMA StoneBreaker™ is indicated for use via a rigid or semi-rigid endoscope with a straight working channel, for the fragmentation of urinary tract (i.e. kidney, ureter and bladder) stones.
Device Story
LMA StoneBreaker is portable, non-electrical, pneumatic contact intracorporeal lithotripter; used for fragmentation of urinary tract stones (kidney, ureter, bladder). Device input: mechanical energy from CO2 gas cartridge; transformation: gas pressure regulated to 31 bars, converted to mechanical shockwave via trigger mechanism; output: mechanical shockwave delivered through probe tip in direct contact with stone. Used in clinical setting by physician via rigid/semi-rigid endoscope with straight working channel. Healthcare provider observes stone fragmentation in situ via endoscope; output facilitates stone removal. Benefits patient by providing high-speed, portable, in-situ stone fragmentation.
Clinical Evidence
No clinical data provided. Substantial equivalence based on operational, technological, and performance data comparisons to predicate devices.
Technological Characteristics
Portable, non-electrical, pneumatic lithotripter. Energy source: detachable high-pressure CO2 gas cartridge (max 31 bars). Probes: 1.0mm, 1.6mm, 2.0mm diameters. Operation: mechanical shockwave generation via trigger-actuated pressure regulator. Delivery: via rigid/semi-rigid endoscope straight working channel. Requires cleaning, disinfection, and sterilization before use.
Indications for Use
Indicated for fragmentation of urinary tract stones (kidney, ureter, bladder) in patients requiring lithotripsy via rigid or semi-rigid endoscope with straight working channel.
Regulatory Classification
Identification
An electrohydraulic lithotriptor is an AC-powered device used to fragment urinary bladder stones. It consists of a high voltage source connected by a cable to a bipolar electrode that is introduced into the urinary bladder through a cystoscope. The electrode is held against the stone in a water-filled bladder and repeated electrical discharges between the two poles of the electrode cause electrohydraulic shock waves which disintegrate the stone.
Special Controls
The special control for this device is FDA's “Guidance for the Content of Premarket Notifications for Intracorporeal Lithotripters.”

#### 2.2 Predicate Device
- Predicate 1: Swiss LithoClast® (for fragmentation of ureteral and bladder stones) already marketed in the USA under K951531
- Predicate 2: Swiss LithoClast® (for fragmentation of ureteral, bladder and kidney stones) already marketed in the USA under K963285
- Predicate 3: Swiss LithoClast® Master already marketed in the USA under K974164
#### Device Description 3.
The LMA StoneBreaker™ is a portable, non-electrical, pneumatic contact intracorporeal lithotripter, intended for use to fragment stones in the urinary tract (i.e. kidney, ureter and bladder). Its weight of approximately 500g with a probe, and with no extraneous electrical or pneumatic connections, makes this device highly portable. It is recommended for use with endoscopes equipped with a straight working channel. The device is powered by a detachable cartridge of high pressure carbon dioxide gas, with a maximum pre-adjusted operating pressure of 31 bars. The mechanical shock generated by the device is transferred through the length of the probe to the tip, which is in direct contact with the stone to be fragmented, providing high speed fragmentation of the calculus in situ.
Three sizes of probe (1.0mm, 1.6mm and 2.0mm) are available for use with the LMA StoneBreaker™
A LMA StoneBreaker™ Carbon Dioxide (CO2) gas cartridge provides the necessary energy for one surgical procedure. Once the cartridge is perforated by the built-in screw system, the compressed gas passes through a pre-adjusted pressure regulator in the device and a mechanical shockwave required for fragmentation of urinary stone is generated when the trigger is depressed.
Expended gas will leave the device through a specially designed exhaust port and the attached exhaust line The trigger snaps back to its starting

position when the gas is expended through the exhaust port, and the device is now ready for further use.
The LMA StoneBreaker™, Probes, Exhaust Line and accessories are delivered non-sterile and it must be cleaned, disinfected and sterilized before initial use and before each subsequent use.
#### 4. Intended Use
The LMA StoneBreaker™ is indicated for use via a rigid or semi-rigid endoscope with a straight working channel, for the fragmentation of urinary tract (i.e. kidney, ureter and bladder) stones.
#### Basis for Substantial Equivalence to Predicate Devices 6.
The proposed device is substantially equivalent to predicate devices Swiss LithoClast® and Swiss LithoClast® Master, which were previously cleared for intracorporeal fragmentation of ureteral and bladder stones under K951531, for kidney stones under K963285 and for kidney, ureteral and bladder stones under K974164. The main differences between the LMA StoneBreaker™ and predicate devices are:
- · Portability The proposed device is hand-held portable lithotripter. Predicate devices are non-portable lithotripter.
- · Energy Source The proposed device is powered by detachable Carbon dioxide gas cartridge. Predicate devices are powered by connection to compressed air.
#### Performance Characteristics 6.
Performance and clinical data are shown in Section 2. The operational, technological and clinical data demonstrate that the LMA StoneBreaker™ is substantially equivalent in safety and effectiveness to that of the predicated devices cited above.

Dear Mr. Boop:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.
If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
