摘要:
A cannula (50) for insertion through a biologic tissue. The cannula (50) includes a shaft (120) having proximal and distal end portions (124, 126) with a lumen (122) therebetween. The cannula (50) further includes a tip (110) having a proximal end portion (114), a distal tip end (142), and a lumen (112) therebetween. The proximal end portion (114) of the tip (110) is secured to the distal end portion (126) of the shaft (120) so that the lumen (112) of the tip (110) is in fluid communication with the lumen (122) of the shaft (120). The tip (110) includes an opening (146) that extends proximally relative to the distal tip end (142) to permit the flow of fluid into the lumen (112) of the tip (110) even in the event that the distal tip end (142) becomes obstructed.
