· General Surgery
· Orthopedic Surgery
· Gynecological Surgery
· Thoracic Surgery
· Laparoscopic Surgery

The Cytori Lipoplasty System is indicated for use when the fragmentation, and aspiration of subcutaneous fatty tissues for aesthetic body contouring is desired.

The Celase Reagent is intended for use in the fragmentation, disaggregation, and liquefaction of soft tissues and subcutaneous fatty tissues within the Lipoplasty System's Collection Canister.

Device Description

The Cytori Lipoplasty System with Celase Reagent is provided in two packaged assemblies: 1). Lipoplasty Unit and 2). Celase Reagent. The Lipoplasty Unit is a single-use disposable device designed to utilize house vacuum to create suction within the hollow liposuction cannula and remove subcutaneous fatty tissue from the patient and transport the adipose tissue into the collection canister. The Celase Reagent is a single-use, non-reusable reagent designed to digest the waste tissue in the collection canister as a means to allow the non-reasons rought designed the screen and mitigate down-stream clogging and blockage in the waste system.

AI/ML Overview

The provided text is a 510(k) premarket notification letter and related documentation for the Cytori Lipoplasty System with Celase Reagent. It establishes substantial equivalence to existing predicate devices but does not contain information about acceptance criteria or a study designed to prove the device meets specific performance acceptance criteria.

The document discusses the device's intended use, design characteristics, material composition, and sterility, and it details its equivalence to existing marketed products (MacroPore Lipoplasty System, Flow Laboratories Trypsin, and Oxoid USA Sputasol).

The only mention of "In Vitro Testing" states: "Mechanical testing of the Cytori Lipoplasty System with Celase Reagent demonstrates that the device is substantially equivalent to the predicate." This is a general statement and does not provide specific acceptance criteria, performance metrics, sample sizes, ground truth establishment, or details of a study setup.

Therefore, I cannot provide the requested information.

Design Characteristics

Design Characteristics
The Cytori Lipoplasty System with Celase Reagent is provided in two packaged assemblies: 1). Lipoplasty The Cyton Lipoplasty of the Lipoplasy Unit is a single-use disposable device designed to utilize house Offit 2). Colast Reagent: The Elipopulasy Only of Carrers.
vacuum to create suction within the hollow liposuction cannula and remove subcutaneous fatty tissue from the patient and transport the adipose tissue into the collection canister. The Celase Reagent is a single-use, non-reusable reagent designed to digest the waste tissue in the collection canister as a means to allow the non-reasons rought designed the screen and mitigate down-stream clogging and blockage in the waste system.

Lipoplasty Unit

The Cytori Lipoplasty System is a sterile, single-use, manual device consisting of a cannula, connection tric cyton Lipopulate collection container that relies on house vacuum for its energy supply. The preassembled Lipoaspirate Unit alleviates assembly errors at the point of care and prevents the misuse of incompatible parts. The cannula handle is attached to the collection canister via connection tubing. The moonline parts. Into cain a single opening near the tip to communicate house vacuum to the tissues and subsequently fragment, emulsify, and aspirate subcutaneous fatty tissues from the patient into the waste collection canister for purposes of aesthetic body contouring. The tip is fabricated from medical waste beinener canable is parposes bricated from medical grade polypropylene. The connection tubing grade stamled from medical grade polyvinyl chloride (PVC) that is DEHP free. The waste collection container is fabricated from medical grade polycarbonate to assure robustness in the operating room environment. The collection canister contains various capped/sealed reagent ports and a 1190 micron filter to trap large tissue masses while allowing liquified tissue to pass through to a hospital-provided collection trap. This mechanism prevents large tissue masses from accumulating and subsequently clogging downstream tubing that could interfere with vacuum.

The Lipoplasty cannula is provided in various sizes ranging from 15cm - 36cm in length and 3.0 - 4.6mm in diameter with a single opening near the tip of the cannula. The tip region of the cannula may have a single or multiple openings that range in size from 4mm to 12mm in length distributed uniformly or randomly throughout the end of the cannula. The handle of the device is 20mm in diameter and may be rancomily in diameters ranging from 20mm in diameter. The connecting tubing is provided with provided in acter of 9.6mm (3/8"), an outer diameter of 14.3mm (9/16"), and a wall thickness of 2.2mm. The tubing that connects the cannula handle to the waste canister is provided in a length of 4 feet and may be provided in lengths ranging from 1 - 8 feet. The bottom of the waste collection container is also provided with the same 3/8" inner diameter connection tubing of various lengths. The proximal end of the exiting connection tubing may be provided with a barbed tubing connector to assist in the attachment of like-sized tubing for purposes of connecting the Cytori Lipoplasty System to house vacuum and/or assorted waste traps. Connection tubing leading to and from the waste collection container is provided with a stepped clamp to facilitate manual control of the vacuum supplied to the cannula. The stepped clamps also allow the operator to seal the connection tubing on both sides of the collection canister and prevent spillage of the collected fluids/tissues, thereby facilitating safe transport and disposal of the waste materials.

Celase Reagent

The Celase Reagent is a mixture of proteolytic enzymes provided in 70mg lyophilized powder form packaged in a single-use unit consisting of an amber vial with a rubber stopper and associated screw-top cap within a foam-protected aluminum canister.

EQUIVALENCE TO MARKETED PRODUCT

The Cytori Lipoplasty System with Celase Reagent shares indications and design principles with the following predicate device which has been determined by FDA to be substantially equivalent to a preamendment device: MacroPore Lipoplasty System (K042261), Flow Laboratories Trypsin (K771955) and Oxoid USA Sputasol (K802493); Class II medical devices that were cleared for marketing in the United States under K042261, K771955, and K802493 respectively.

Indications For Use

The Cytori Lipoplasty System with Celase Reagent and the MacroPore Lipoplasty System predicate device share substantially equivalent indications for use as they are both indicated for the fragmentation, emulsification and aspiration of soft tissues in aesthetic body contouring procedures and are indicated for the same surgical specialties. The Cytori Lipoplasty System with Celase Reagent shares indications for use language with the predicate devices.

Design and Materials

The design and materials of Cytori Lipoplasty System with Celase Reagent and the predicate device (MacroPore Lipoplasty System) are substantially equivalent as they both utilize a hollow tubular cannulas attached to a handle. The cannula tip of the subject device and the predicate devices contains one or several openings to allow communication between the applied vacuum and the patient's tissues. The Cytori Lipoplasty System with Celase Reagent and the MacroPore Purice! Lipoplasty System predicate device are substantially equivalent in design as they both consist of a cannula, connection tubing, and a waste collection container. The waste collection containers on the Cytori Lipoplasty System with Celase Reagent and the MacroPore Puricel Lipoplasty System predicate device are provided in substantially equivalent volume capacities. The Cytori Lipoplasty System with Celase Reagent and the predicate devices (Trypsin and Sputasol Reagents) are substantially equivalent as they all enzymatically digest tissues and cells in vitro.
