Intended Use

The Aesculap BiPolar Cup is for uncemented use in conjunction with a standard cemented or uncemented femoral replacement implant for the following: - Non-inflammatory degenerative joint disease including osteoarthritis and avascular necrosis - Rheumatoid arthritis - Correction of functional deformity - Treatment of non-union, femoral neck fracture and trochanteric fractures of the proximal femur with head involvement, unmanageable using other techniques

Device Story

BiPolar Acetabular Cup functions as artificial femoral head in hip hemi-arthroplasty; consists of highly polished CoCrMo shell and UHMWPE insert; includes pre-assembled polyethylene retaining ring. Device articulates with patient's acetabulum while insert articulates with modular femoral head of hip stem. Used in orthopedic surgery; implanted by surgeons. Self-centering design; available in various sizes to restore hip anatomy. Benefits patient by replacing damaged femoral head, restoring joint function, and addressing degenerative disease or fractures.

Clinical Evidence

Bench testing only. Biomechanical testing performed to evaluate effects of destructive forces on the ball/cup assembly for both 22 mm and 28 mm head diameters at extreme size ranges.

Technological Characteristics

Materials: Cobalt Chrome alloy (CoCrMo) shell, UHMWPE insert. Design: BiPolar cup with polyethylene retaining ring; self-centering. Dimensions: 22 mm or 28 mm head compatibility; outer diameters 39 mm to 60 mm. Energy source: None (mechanical). Connectivity: None. Sterilization: Not specified.

Indications for Use

Indicated for patients requiring hip hemi-arthroplasty due to non-inflammatory degenerative joint disease (osteoarthritis, avascular necrosis), rheumatoid arthritis, functional deformity, or proximal femur fractures (non-union, femoral neck, trochanteric) with head involvement.

Regulatory Classification

Identification

A hip joint femoral (hemi-hip) metal/polymer cemented or uncemented prosthesis is a two-part device intended to be implanted to replace the head and neck of the femur. This generic type of device includes prostheses that have a femoral component made of alloys, such as cobalt-chromium-molybdenum, and a snap-fit acetabular component made of an alloy, such as cobalt-chromium-molybdenum, and ultra-high molecular weight polyethylene. This generic type of device may be fixed to the bone with bone cement (§ 888.3027) or implanted by impaction.

# SUBSTANTIAL EQUIVALENCE

Aesculap®, Inc. believes that the BiPolar Acetabular Cup is substantially equivalent to the following legally marketed predicate devices:

Biomet Ringloc Bi-Polar Acetabular Component (K051569)

Plus Orthopedics Bipolar Prosthesis CoCrMo (K982447)

Aesculap Excia Total Hip System (K042344)

Aesculap BiContact Hip Stem and Femoral Head (K040191)

# DEVICE DESCRIPTION

The BiPolar cup is a sub-component of an endoprosthetic replacement for the human hip where it assumes the function of the natural femoral head and is combined with a prosthesis head and a hip stem. It consists of a highly polished CoCr shell and a polyethylene insert. In vivo, the shell articulates directly with the well-preserved acetabulum while the insert articulates with a modular head component of a femoral hip. The head is held in place by a retaining ring that is pre-assembled into the insert of the cup. The BiPolar components are available in a variety of sizes to allow the surgeon to rebuild the natural anatomy of the hip joint as accurately as possible while implanting the hemi-arthroplasty.

# INDICATIONS FOR USE

The Aesculap BiPolar Cup is for uncemented use in conjunction with a standard cemented or uncemented femoral replacement implant for the following:

- Non-inflammatory degenerative joint disease including osteoarthritis and avascular 1) necrosis
- Rheumatoid arthritis 2)
- Correction of functional deformity 3)
- Treatment of non-union, femoral neck fracture and trochanteric fractures of the 4) proximal femur with head involvement, unmanageable using other techniques

# TECHNOLIGICAL CHARACTERISTICS(compared to predicate(s))

This is exactly the same Bipolar cup that was cleared for Plus Orthopedics in 510(k) # K982447 as thev are both made by the subcontractor Ortek A.G. in Switzerland. This BiPolar Cup is marketed by Aesculap for use with the femoral components of their previously cleared Excia and BiContact Hip Systems. Just like the Plus and Biomet devices this new Aescular Acetabular Cup will be made with a highly polished Cobalt Chrome alloy (CoCrMo) shell and a polyethylene (UHMWPE) insert. All three devices use a locking ring mechanism, the Aesculap device is the same as the Plus device using a polyethylene ring while the Biomet device uses a metal ring. Both the Aesculap and Plus Bipolar Cups are self-centering as well. The devices are offered to fit either 22 mm or 28 mm heads and are available in a range of outer diameters from 39mm to 60 mm. The Biomet predicate O.D. ranqe is from 41 mm to 70 mm.

## PERFORMANCE DATA

Biomechanical testing was performed to evaluate the effects of destructive forces on the ball/ cup assembly for both head diameters at the extreme size ranges.
