Invamed tarafından sunulan Dolphin® Zebra Geçiş Kateteri, çizgili " zebra " deseni ve yüksek esneklikli tasarımıyla öne çıkan özel bir geçiş destek kateteridir . Karmaşık veya kronik total oklüzyon (CTO) lezyonlarından kılavuz tel geçişini kolaylaştırmak için geliştirilen şafttaki Zebra deseni, floroskopik görünürlüğü artırarak, zorlu periferik veya koroner müdahalelerde lezyona daha iyi erişim ve hassas kılavuz tel desteği sağlar.
Gelişmiş Görünürlük için Zebra Çizgileri
•Kateter şaftı, floroskopi altında kontrastı artıran ve kıvrımlı veya tıkalı damarlarda gerçek zamanlı pozisyonel farkındalığa yardımcı olan belirgin çizgili bir desene sahiptir.
High Pushability & Torque
•Braided or coiled shaft architecture delivers robust torque response, critical for navigating complex plaque or calcific lesions.
Low-Friction Coating (Optional)
•Minimizes vessel resistance, promoting seamless advancement in subintimal or heavily diseased segments.
Versatile Clinical Utility
•Suitable for peripheral artery disease (PAD) and complex coronary CTO crossing, offering a stable support platform for balloon/stent delivery devices.
