摘要
The method and system disclosed herein uses a pulsatile, dilatory bubble at the tip of a catheter to facilitate tissue separation and ease catheter insertion for, among other applications, delivery of therapeutics to the posterior of the eye while reducing procedure-related trauma. In some implementations, the method is extended to other dilatory and catheter-insertion applications elsewhere in the body. In brief, the disclosure discusses iteratively injecting liquid through a catheter to form a bubble near the distal tip of the catheter. The liquid is withdrawn to create a void, and the catheter is advanced into the void. The process is repeated until the distal tip of the catheter reaches the target location.
