Alternative designs, materials and manufacturing methods for guidewires. Some embodiments pertain to a guidewire having a core wire including a proximal section defining a proximal end and a distal section defining a distal end. The proximal section having a uniform diameter extending from adjacent the proximal end to adjacent the distal section. The distal section having a reduced diameter relative to the proximal section. A tubular polymer layer having an textured outer profile configured to enhance the ability of a user to grip the tubular polymer layer is disposed about a portion of the uniform diameter proximal section of the core wire.
L'invention concerne des modèles, des matières et des procédés de fabrication différents pour fils guides. Certains modes de réalisation ont trait à un fil guide possédant un fil central à section proximale formant une extrémité proximale et à section distale formant une extrémité distale. Ladite section proximale possédant un diamètre uniforme s'étendant de l'extrémité proximale à la section distale. Ladite section distale possède un diamètre réduit par rapport à la section proximale. Une couche polymère tubulaire à profil externe texturé élaboré pour améliorer la capacité de préhension de ladite couche par un utilisateur est disposée autour d'une partie de la section proximale à diamètre uniforme du fil central.
