Intended Use
The Poly/Platinum Pistons are intended for the elective reconstruction of the ossicular chain to facilitate conduction of sound energy from the ear drum to the inner ear. The prosthesis is implanted into the middle ear during a tympanoplasty procedure and is retained in the middle ear by the design configuration of the device.
Device Story
Middle ear implant; used for ossicular chain reconstruction; facilitates sound conduction from eardrum to inner ear. Device consists of shaft with loop for ossicular attachment. Implanted during tympanoplasty by qualified healthcare professional. Single-patient use; sterile packaged. Solid ultra-high molecular weight polyethylene (UHMWPe) shaft; platinum component. Retained in middle ear via design configuration.
Clinical Evidence
No clinical data; bench testing only.
Technological Characteristics
Middle ear prosthesis; materials: solid ultra-high molecular weight polyethylene (UHMWPe) and platinum. Design: shaft with loop for ossicular attachment. Sterile packaged; single-patient use.
Indications for Use
Indicated for patients requiring elective ossicular chain reconstruction during tympanoplasty to facilitate sound conduction from the eardrum to the inner ear.
Regulatory Classification
Identification
A partial ossicular replacement prosthesis is a device intended to be implanted for the functional reconstruction of segments of the ossicular chain and facilitates the conduction of sound wave from the tympanic membrane to the inner ear. The device is made of materials such as stainless steel, tantalum, polytetrafluoroethylene, polyethylene, polytetrafluoroethylene with carbon fibers composite, absorbable gelatin material, porous polyethylene, or from a combination of these materials.
