Catheter having a low-friction guidewire lumen and method of manufacture |
摘要 |
A catheter shaft for a catheter includes a centrally-located guidewire lumen. A body portion of the catheter shaft includes arc-shaped nodes that define a guidewire track within the guidewire lumen. The nodes include a crown region that includes a single contact point for the guidewire and may be formed of a material having a lower coefficient of friction. At least one node has an inflation lumen extending therethrough. The catheter shaft has a cut in it extending radially from the guidewire lumen to an exterior surface of the catheter shaft. The balloon catheter has a guide member that opens the cut and tracks the guidewire in and out of the catheter shaft along a length of the catheter shaft which is cut.
