This abstract first appeared for US patent application 18947203 titled 'MEDICAL ACCESS SHEATHS

Original Abstract Submitted

A tapered medical access sheath can comprise an access sheath hub and an access sheath shaft extending distally from the access sheath hub. The access sheath shaft can comprise a first delivery lumen extending from a proximal end of the access sheath shaft to a side opening on a distal portion of the access sheath shaft, the first delivery lumen having a width configured to slidably receive a distal portion of a medical device disposed around a guidewire. The access sheath shaft can comprise a tapered distal end portion disposed distally of the side opening. A recess can extend along a longitudinal dimension of the tapered distal end portion from a proximal end to a distal end of the tapered distal end portion. The recess can be in fluid communication with the first delivery lumen and have a width smaller than the diameter of the first delivery lumen.
