POSITIONING CATHETER |
| 摘要 |
A catheter guide assembly includes an extended working channel having a proximal portion adjacent a proximal end and a distal portion adjacent a distal end, the extended working channel having a lumen configured to enable translation of an instrument therethrough. The extended working channel defines a radius formed on the distal portion, wherein the distal portion of the extended working channel is formed of a material having a durometer rating sufficient such that deflection of the distal portion is limited as the instrument is translated therethrough. The catheter guide assembly includes a control handle disposed at the proximal end of the extended working channel and operably coupled to the extended working channel, thereby enabling the extended working channel to advance and rotate. |

1. A catheter guide assembly, comprising:
an extended working channel including a proximal portion adjacent a proximal end and a distal portion adjacent a distal end, the extended working channel having a lumen configured to enable translation of an instrument therethrough, the extended working channel defining a radius formed on the distal portion, wherein the distal portion of the extended working channel is formed of a material having a durometer rating sufficient such that deflection of the distal portion is limited as an instrument is translated therethrough; a control handle disposed at the proximal end of the extended working channel and operably coupled to the extended working channel, thereby enabling the extended working channel to advance and rotate. |
