Intended Use

The Günther Tulip™ Vena Cava Filter Set is indicated for placement in the vena cava in the following situations: Pulmonary thromboembolism when anticoagulation therapy is contraindicated; failure of anticoagulation therapy in thromboembolic diseases; emergency treatment following massive pulmonary embolism where anticipated benefits of conventional therapy are reduced; and chronic, recurrent pulmonary embolism where anticoagulation therapy has failed or is contraindicated. The Günther Tulip™ Vena Cava Filter™ may be retrieved according to the instructions supplied in the section labeled: Optional Retrieval Procedure. The Günther Tulip™ Vena Cava Filter Retrieval Set has been designed for retrieval of the Günther Tulip™ Vena Cava Filter in patients who no longer require a filter. Retrieval of the filter can be performed only by jugular approach.

Device Story

The Günther Tulip Vena Cava Filter is a conical, four-legged metallic filter designed to trap emboli in the vena cava. It is constructed from a Co, Cr, Ni, Mo, and Fe alloy. The filter features hooked leg ends and webbed wires between legs to maintain shape and increase trapping area. The device is provided in femoral or jugular introduction sets, including radiopaque dilators, coaxial introducer sheaths, and loading systems. A separate retrieval set allows for filter removal via a jugular approach in patients no longer requiring filtration. The device is used by clinicians in a hospital setting to prevent pulmonary embolism. It functions as a mechanical barrier; clinical decision-making is based on the patient's contraindication to or failure of anticoagulation therapy.

Clinical Evidence

Bench testing only. Testing included simulated transport, biocompatibility, deployment, package, and lubricity testing to ensure design and performance conformance.

Technological Characteristics

Conical filter design with four legs and webbed wires. Material: Co, Cr, Ni, Mo, and Fe alloy. Components include radiopaque dilators, coaxial introducer sheaths (7F or 8.5F), and loading systems. Non-software, mechanical device.

Indications for Use

Indicated for patients requiring vena cava filtration for pulmonary thromboembolism when anticoagulation is contraindicated, anticoagulation therapy has failed, or in emergency cases of massive pulmonary embolism. Retrieval is indicated for patients who no longer require the filter.

Regulatory Classification

Identification

A cardiovascular intravascular filter is an implant that is placed in the inferior vena cava for the purpose of preventing pulmonary thromboemboli (blood clots generated in the lower limbs and broken loose into the blood stream) from flowing into the right side of the heart and the pulmonary circulation.

Special Controls

*Classification.* Class II. The special controls for this device are:(1) “Use of International Standards Organization's ISO 10993 ‘Biological Evaluation of Medical Devices Part I: Evaluation and Testing,’ ” and (2) FDA's: (i) “510(k) Sterility Review Guidance and Revision of 2/12/90 (K90-1)” and (ii) “Guidance for Cardiovascular Intravascular Filter 510(k) Submissions.”

Date Prepared: February 18, 2005

#### Device:

| Trade Name: | Günther Tulip Vena Cava Filter Set |
|--------------------------|------------------------------------|
| Proposed Classification: | 870.3375 DTK |
| | Class II, Cardiovascular |

#### Predicate Devices:

The Günther Tulip Vena Cava Filter Set is similar in terms of intended use, materials of construction and technological characteristics as the predicate Günther Tulip MReye™ Vena Cava Filter Set (K000855) and the Günther Tulip™ Vena Cava Filter and Retrieval Set (K032426).

#### Device Description:

The Günther Tulip Vena Cava Filter is crafted of an alloy consisting of Co, Cr, NI, Mo and Fe. The basic design of the filter is conical with four legs. The end of each leg is slightly hooked outward. "Webbed" wires (like tulip petals) between the legs are bent strands of the same alloy which maintain the shape of the filter by pressing outward toward the vein walls. These webs also increase the area into which the emboli can be trapped.

{1}------------------------------------------------

There are two types of Günther Tulip Vena Cava Filter Sets a femoral set which is introduced through the femoral vein and a jugular set which is introduced through the jugular vein.

The jugular set consists of: the Günther Tulip Vena Cava Filter with a protective sleeve, a 10 French Radiopaque Dilator, a 7 French Radiopaque Coaxial Introducer Sheath 65 centimeters long, a filter loading introducer with a pre-attached Günther Tulip Vena Cava Filter, a proximal protective sleeve to introducer, a Radiopaque polyethylene inner catheter, and a three-way stopcock.

The femoral set consists of: the Günther Tulip Vena Cava Filter with a protective sleeve, a 10 French Radiopaque Dilator, a 8.5 French Radiopaque Coaxial Introducer Sheath 65 cm long, a Radiopaque polyethylene inner catheter, a three-way stopcock and a 10 French filter loading introducer system preloaded with a Günther Tulip Vena Cava Filter.

The Günther Tulip™ Vena Cava Filter Retrieval Set has been designed for retrieval of an implanted Günther Tulip™ Vena Cava Filter in patients who no longer require a filter. Retrieval of the filter can be performed only by jugular approach.

#### Substantial Equivalence:

This device will be manufactured according to specified process controls and a Quality Assurance Program. This device will undergo packaging similar to the devices currently marketed and distributed by Cook Incorporated. This device will undergo sterilization similar to the devices currently marketed and distributed. Being similar with respect to indications for use, materials and physical construction to predicate devices, we believe this device meets the requirements for section 510(k) substantial equivalence.

#### Test Data:

The Günther Tulip Vena Cava Filter Set was subjected to the following tests to assure reliable design and performance under the specified testing parameters. These tests were comprised of:

- Simulated Transport Testing 1.
- Biocompatibility Testing 2.
- Deployment Testing 3.
- Package Testing 4.
- Lubricity Testing న్ :

The results of these tests provide reasonable assurance that the device has been designed and tested to assure conformance to the requirements for its use as a vena cava filter set.
