Abstract
A cannula for insertion through a biologic tissue. The cannula includes a shaft having proximal and distal end portions with a lumen therebetween. The cannula further includes a tip having a proximal end portion, a distal tip end, and a lumen therebetween. The proximal end portion of the tip is secured to the distal end portion of the shaft so that the lumen of the tip is in fluid communication with the lumen of the shaft. The tip includes an opening that extends proximally relative to the distal tip end to permit the flow of fluid into the lumen of the tip even in the event that the distal tip end becomes obstructed.
