Catheter Cook K-Jets-551910-S
Catheter Cook k-soft-5000 (or K-J-SP-681710, K-J-SPPE-68171)
Catheter Cook K-Jets-551910-S consists of an outer firm and an inner ultrasoft catheter. The outer guiding catheter (17 cm long) is slightly stiff, with a preshaped curve and a rounded bulb tip to help negotiate the cervical canal. It has a depth marker at 4 cm from the tip, which can be pulled back to a second marker at 5 cm. The inner catheter (23 cm long) is made of a soft material with a rounded bullet tip. In general, the inner catheter does not negotiate the cervical canal directly but rather is introduced into the uterine cavity through the outer catheter.
This catheter system consists of an outer firm and inner soft catheter. The outer guiding catheter (15,4 cm long) is straight and made of flexible material. The inner catheter (23 cm long) is made of a very soft and flexible polyurethan. The inner catheter is introduced directly through the cervix.
