Catheter assembly for e.g. angioplasty procedure, has core including cavity for passage of guide-wire extending over opening in intermediate parts and has its position displaced from proximal side with respect to sheath

摘要

The assembly has a sheath and a core with proximal circular parts (10, 20) defining intermediate parts (12, 22) and distal parts (14, 24). The core has a cavity for passage of a guide-wire (30) extending via an opening. The core has its position displaced from a proximal side with respect to the sheath in assembly`s insertion position. Intermediate parts of the core and an internal part of the sheath are complementary to each other.
