摘要： A lockable sleeve drainage catheter is disclosed for percutaneous insertion into a patient and drainage of fluid therefrom. The drainage catheter includes a flexible distal end that is preformed for retaining the distal end of the catheter that is inserted in the patient. For insertion, the distal end is straightened with the use of a stiffening cannula that is inserted through the hollow passageway of the catheter. When the catheter is inserted in the patient, the stiffening cannula is removed, and a flexible tension member positioned within the passageway of the catheter is drawn to position the distal end in the desired retention configuration. A lockable sleeve positioned at the proximal end of the catheter draws the flexible tension member through the passageway of the elongated member tube to position the distal end in the retention configuration. The catheter also includes a locking collar at the proximal end of the elongated member tube having an annular recess formed therein. The distal end of the lockable sleeve includes an annular step for engaging the recess of the collar and locking the sleeve in a fixed position relative to the elongated member tube of the catheter. When fully extended and locked, the sleeve and elongated member form a fluid tight interconnection. A Luer lock connector is affixed to the proximal end of the sleeve for connection to a drainage collection system.

摘要翻译：公开了一种可锁定袖子排液导管，用于经皮插入患者体内并从中排出流体。引流导管包括柔性远端（105），其被预成型以保持插入患者体内的导管的远端（105）。为了插入，使用插入穿过导管的中空通道（107）的加强套管使远端（105）矫直。当导管插入患者体内时，去除加强插管，并且定位在导管的通道（107）内的柔性张力构件（121），以将远端（105）定位在期望的保持构型。定位在导管的近端（106）处的可锁定套管（110）通过细长构件管（104）的通道（107）将柔性张紧构件（121）拉动，以将远端（105）定位在保持组态。导管还包括在细长构件管（104）的近端（106）处的锁定套环（114），其具有形成在其中的环形凹部（119）。可锁定套管（110）的远端（111）包括用于与套环（114）的凹部（119）接合并将套筒（110）相对于细长构件管锁定在固定位置的环形台阶（120）（104）。当完全延伸和锁定时，套筒（110）和细长构件（104）形成流体密封互连。 Luer锁定连接器（124）固定到套筒（110）的近端（112），用于连接到排水收集系统。
