We agree with Drs. Wardhan and Nimma that the suture-catheter system is simpler in design than conventional through-the-needle catheters and that no system will be perfect in design, ergonomics, or ease of placement. However, our experience with the catheter insertion system differs from their suggestion that relative to a straight needle, the suture shape is more difficult to visualize. As our study progressed, we were somewhat surprised to discover that the 19-gauge suture needle visualized at least as well, if not better, than a Tuohy needle of the same gauge. Drs. Wardhan and Nimma note that “lateral forces exerted on [a] straight needle tip leading to curvature may lead to an unpredictable needle trajectory which cannot always be assumed to be straight or even in a single two-dimensional plane.” We concur and suggest that the suture-shaped...
