No
The document describes a mechanical biopsy device that uses cold temperatures and a cutting cannula to obtain tissue samples. There is no mention of AI or ML in the description of the device's operation or intended use.
No
The device is used for obtaining biopsies and tissue sampling, which is a diagnostic procedure to determine the nature of an abnormality, not to treat it.
No
Explanation: The device is used to obtain tissue samples for histological examination, which is a method of acquiring data (the tissue sample) about an abnormality, rather than directly diagnosing it. The histological examination itself (performed by a pathologist) would be the diagnostic step.
No
The device description clearly outlines multiple hardware components including a handle, valve block, battery, cryogen, needle, and sample collection tray. There is no mention of software being the primary or sole component.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens (like blood, urine, or tissue) outside of the body to provide information about a person's health.
- Device Function: The Cassi Rotational Core Biopsy Device is used to obtain tissue samples from the body. It is a surgical/biopsy device, not a device that analyzes samples in a lab.
- Intended Use: The intended use clearly states it is for "obtaining biopsies from soft tissues" and "provide breast tissue sampling." This is a tissue collection function, not an in vitro diagnostic function.
- Device Description: The description details the mechanical components used to extract tissue, not components for analyzing biological samples.
The tissue samples obtained by this device may then be sent to a laboratory for in vitro diagnostic testing (like histology), but the Cassi device itself is not the IVD.
N/A
Intended Use / Indications for Use
The Cassi Rotational Core Biopsy Device is indicated for use in obtaining biopsies from soft tissues such as liver, kidney, prostate, spleen, lymph nodes, and various soft tissue tumors. It is not intended for use in bone.
The Cassi Device is also indicated to provide breast tissue sampling of breast abnormalities. It is designed to provide breast tissue for histological examination with partial or complete removal of the imaged abnormality. The extent of a histological abnormality cannot be reliably determined from its mammographic appearance. Therefore, the extent of removal of the imaged evidence of an abnormality does not predict the extent of removal of a histological abnormality (e.g. malignancy). When the sampled abnormality is not histologically benign, it is essential that the tissue margins be examined for completeness of removal using standard surgical procedures.

Device Description
The proposed CASSI II Rotational Core Biopsy System consists of the following primary components: a fully integrated CASSI biopsy handle, a valve block, battery, cryogen, a Cassi biopsy needle (CASSI biopsy needle comprised of a sticking needle and cutting cannula/piston assembly), and a sample collection tray. The sticking needle is operated by CASSI biopsy handle and uses cold temperatures at its tip to engage the tissue to be sampled. The cutting cannula is coaxially mounted around the sticking needle and is used to core the tissue specimen. The cutting cannula is available in two sizes (10 and 12 gauge).
The proposed CASSI biopsy handle are minor design evolution of the predicate CASSI II biopsy handle. The proposed CASSI II biopsy needle unit assembly remains unchanged from the predicate CASSI II biopsy needle unit assembly.
The proposed CASSI II system uses one control unit handle and allows for multiple, single patient use, biopsy needle units to operate with the handle (See Figure 1, below), in the very same manner as the predicate CASSI II device. The principles of operation for the proposed CASSI™ II Rotational Core Biopsy System and the predicate CASSI II system remain unchanged.

E) Device Description
The proposed CASSI II Rotational Core Biopsy System consists of the following primary components: a fully integrated CASSI biopsy handle, a valve block, battery, cryogen, a Cassi biopsy needle (CASSI biopsy needle comprised of a sticking needle and cutting cannula/piston assembly), and a sample collection tray. The sticking needle is operated by CASSI biopsy handle and uses cold temperatures at its tip to engage the tissue to be sampled.

The proposed CASSI biopsy handle are minor design evolution of the predicate CASSI II biopsy handle. The proposed CASSI II biopsy needle unit assembly remains unchanged from the predicate CASSI II biopsy needle unit assembly.
The proposed CASSI II system uses one control unit handle and allows for multiple, single patient use, biopsy needle units to operate with the handle (See Figure 1, below), in the very same manner as the predicate CASSI II device. The principles of operation

for the proposed CASSI™ II Rotational Core Biopsy System and the predicate CASSI II system remain unchanged.
Image /page/4/Figure/1 description: The image shows a disassembled electronic thermometer. The thermometer consists of two main parts: a probe and a handheld unit. The probe is long and slender, with a pointed tip for insertion into food. The handheld unit has a digital display and buttons for operation. The two parts are designed to be connected together for use.

Additionally, minor design evolutions of the predicate CASSI II biopsy handle are as follows:
-
- Added PCBA coating. The purpose is to mitigate the possibility of moisture or chemical contaminating the components of the board and protect the component of the board (e.g. ESD).
-
- Add JB weld adhesive to the valve body (See Figure 2). The purpose is to enhance the valve body strength and mitigate the risk of valve crack caused by thermal shock.
-
- Changed the shelf life of CASSI QuadPoint disposable biopsy needle unit from 1 year to 3 years.

The drawing shows the different components of the device, including the biopsy needle unit, canister, canister cap, battery, timer circuit board, valve block, and biopsy needle unit receptacle. The drawing is labeled with the names of the components.
F) Intended Use/Indications For Use:
The Indications for Use, of the proposed CASSI II Rotational Core Biopsy System remain unchanged from the cleared CASSI II Rotational Core Biopsy System predicate device (K123606).
The Cassi Rotational Core Biopsy System is indicated for use in obtaining biopsies from soft tissues such as liver, kidney, prostate, spleen, lymph nodes, and various soft tissue tumors. It is not intended for use in bone.
The Cassi Rotational Core Biopsy System is also indicated to provide breast tissue samples for diagnostic sampling of breast abnormalities. It is designed to provide breast tissue for histological examination with partial or complete removal of the imaged abnormality. The extent of a histological abnormality cannot be reliably determined from its mammographic appearance. Therefore, the extent of removal of the imaged evidence of an abnormality does not predict the extent of removal of a histological abnormality (e.g., malignancy).
When the sampled abnormality is not histologically benign, it is essential that the tissue margins be examined for completeness of removal using standard surgical procedures.
G) Substantial Equivalence Comparison and Discussion
In summary, Scion Medical Technologies, LLC believes that the proposed changes, as described in this submission, do not raise any new or significant questions of safety and efficacy and is substantially equivalent to the predicate Scion Medical Technologies, LLC CASSI II Rotational Core Biopsy System cleared on March 1st, 2013 (K123606)
H) Compliance with Design Controls
The results of assessment of the change to the CASSI™ II Rotational Core Biopsy System, conducted under Design Controls, support that the new offering is substantially equivalent to the predicate device delivery system.
