A device, consisting of a round base and cap made of polytetrafluoroethylene, was made to exteriorize and protect chronically implanted arterial and venous catheters in conscious dogs. In experiments lasting as long as 9 months, the subcutaneously implanted button-like appliance did not cause tissue reactions and was well tolerated by 98% of a group of 200 dogs. Being maintenance-free, having the capacity to exteriorize several catheter or wire outputs, and needing no protective harness were advantages of the device.
制作了一种由聚四氟乙烯制成的圆形底座和盖子组成的装置，用于使清醒犬体内长期植入的动静脉导管外置并加以保护。在长达9个月的实验中，皮下植入的纽扣状装置未引起组织反应，200只犬组成的一组中有98%对其耐受性良好。该装置具有无需维护、能够使多个导管或导线引出体外以及无需保护束带等优点。
