摘要： A catheter comprising a flexible proximal portion and a rigid distal portion having a beveled needle tip. The beveled tip overcomes coring of a barrier such as a septum of an implanted percutaneous drug delivery port when the needle tip passes therethrough for ultimate insertion of the catheter within the port. The invention also includes a catheter assembly incorporating the above-defined catheter along with a hand-operable implantation grip having a stylet member extending into the catheter and two opposing parallel finger members adjacent the catheter therebetween for holding the catheter during introduction thereof into an implanted percutaneous drug delivery port. The invention additionally includes methodology for catheterizing a percutaneous drug delivery port implanted in a living being through utilization of the catheter assembly and manually manipulating the grip thereof to insert the catheter tip into the port for long term implantation.
摘要翻译：导管，其包括柔性近端部分和具有斜面针尖的刚性远侧部分。当针尖通过其中时，倾斜的尖端克服了诸如植入的经皮药物输送口的隔膜之类的屏障的取芯，以将导管最终插入端口内。本发明还包括一个导管组件，其结合了上述定义的导管以及一个可手动操作的植入手柄，其具有延伸到导管中的探针构件，以及两个相邻的平行指状构件，位于其间的导管，用于在导入植入的经皮药物输送口。本发明另外包括用于通过利用导管组件导入植入生物体内的经皮药物递送口的方法，并且手动操作其把手以将导管末端插入端口用于长期植入。
