A new self-expanding tulip sheath was tested for percutaneous wife capturing in a femoro-femoral pull-through maneuver.
In six sheep, a self-expanding tulip sheath was introduced into the right iliac artery. A 5 Fr catheter and an 0.035-inch guidewire were guided into the iliac artery from a left femoral approach. Thirty-six tests were performed to guide the guidewire out of the right groin using the tulip sheath, by catching the catheter first in 18 tests and just by catching the guidewire in the other 18. As a control, six tests were performed using a conventional sheath. We performed one clinical arterial application.
There was prompt capture of the wire in 35 of 36 tests using a self-expanding sheath. Five of six tests using a conventional sheath failed. The clinical application of the tulip principle was successful.
Using the self-expanding tulip sheath to facilitate wire capture during pull-through maneuvers, even in difficult situations, is promising.
对一种新型自膨式郁金香鞘管进行测试，以评估其在股-股牵引操作中经皮捕获导丝的能力。
在6只绵羊中，将自膨式郁金香鞘管插入右髂动脉。通过左股动脉途径将一根5F导管和一根0.035英寸导丝引入髂动脉。使用郁金香鞘管进行了36次测试，以引导导丝穿出右腹股沟，其中18次先捕获导管，另外18次仅捕获导丝。作为对照，使用传统鞘管进行了6次测试。我们进行了一次临床动脉应用。
使用自膨式鞘管的36次测试中有35次能迅速捕获导丝。使用传统鞘管的6次测试中有5次失败。郁金香原理的临床应用成功。
使用自膨式郁金香鞘管在牵引操作中便于捕获导丝，即使在困难情况下也很有前景。
