Cook Medical localization devices mark breast lesions prior to surgery

Cook Medical’s breast lesion localization devices:
1 MReye® Breast Lesion Localization Coil
2 Kopans Breast Lesion Localization Needle
3 X-Reidy Breast Lesion Localization Needle

In a report published in 2017, the World Cancer Research Fund International indicates that breast cancer is the most common cancer in women worldwide, with nearly 1.7 million new cases diagnosed in 2012 (second most common cancer overall). This represents about 12% of all new cancer cases and 25% of all cancers in women. It is the fifth most common cause of death from cancer in women.¹ The top 10 countries with the highest incidence of breast cancer are (1) Belgium, (2) Denmark, (3) France, (4) the Netherlands, (5) the Bahamas, (6) Iceland, (7) the United Kingdom, (8) Barbados, (9) the United States, and (10) Ireland.¹

Cook Medical offers a suite of breast lesion localization devices, which assist physicians in accurately locating breast lesions during surgery. The Kopans Breast Lesion Localization Needle, the MReye® Breast Localization Coil, and the X-Reidy Breast Lesion Localization Needle are intended for preoperative marking of nonpalpable breast lesions.

In addition to its standard needle, the Kopans Breast Lesion Localization Needle product line offers both echogenic and MR conditional options. Unlike standard, smooth-surfaced needles, EchoTip echogenic devices have textured surfaces. Textured surfaces help make the needles more visible under ultrasound.^2,3 The EchoTip surface contains a band of microscopic dimpling around the full circumference of the needle shaft, close to the needle tip, for increased echo reflection. (Similarly, Cook’s textured etched tip needles contain finely roughened surfaces on the needle tip itself to help users detect the location of the needle tip for positioning.) The MReye versions of the Kopans needle are MR Conditional up to 1.5T. Kopans needles, in their smooth, echogenic and MR Conditional versions, are available in varying gages and lengths.

Additional features of the Kopans breast lesion localization needle include:

• A reference burnish mark, when visible just outside the needle hub on the spring-hook wire, provides visual assurance that the hook wire is within the needle tip during needle manipulation.
• The needle is marked in 1 cm increments for depth guidance during a procedure.
• The reinforced tip of the spring-hook wire serves as a visual and palpable landmark for the surgeon to gauge distance to the lesion during dissection and reduces the risk of severing the hook wire.

The MR conditional MReye® Breast Localization Coil acts as a marker to indicate the location of the lesion for the surgeon. It is created from a non-ferromagnetic material: a nickel-based super alloy called Inconel®,⁵ which has been shown to cause smaller, or fewer, image artifacts in MR imaging than stainless steel.^4,6 The coil is MR Conditional up to 3T. The two-part positioning needle through which the coil is delivered contains EchoTip technology.

The X-Reidy Breast Lesion Localization Needle Set consists of a needle and a hook wire with a palpable 3 cm stiff segment just proximal to the X-shaped hook for easy palpation during surgery. The distinctive X-shaped hook provides fixation and is intended to limit migration. The remaining part of the hook wire is soft and flexible for patient comfort. A slide clamp is provided for use as a skin marker.
