Selective surface modification of catheter tubing |
摘要 |
A catheter shaft and methods for making and using the same. The catheter shaft may include a core portion, a cap portion, and one or more lumens. The cap portion may be disposed on or over a section of the core portion and define a region with a different exterior or interior surface characteristic. For example, the cap portion may define a lubricious region along the catheter shaft. Manufacturing the catheter shaft may include a modified co-extrusion process that incorporates a flow valve on at least one of the material supply lines so that the supply line can be regulated by a user. |
