Abstract

A vascular introducer sheath device comprising a tubular main shaft and main hub attached to the proximal end of the main shaft. Attached to the proximal end of the main hub is a header hub having a first arm and second arm. The header hub is attached to the main hub in a releasably locked configuration and functionally detachable from the main hub. The header hub and main hub could together have a twist-on or snap-on mating mechanism. An example of such a mating mechanism is a male lock fitting on the header hub and a female lock fitting on the main hub. There could be a side port on the main hub and a side port on the header hub, wherein the side ports for the main hub and header hub are oriented on a same plane when the header hub and the main hub are in locked configuration.

Claims9

Dependent claims

A vascular introducer sheath device comprising:

a tubular main shaft having a proximal end, a distal end, and a shaft passage;
a main hub having a proximal end, a distal end, and a main hub passage;
wherein the main hub is attached to the proximal end of the main shaft;
a header hub having a proximal end, a distal end, and a header passage;
wherein the header hub has a first arm having a first passage that is in coaxial orientation to the shaft passage and a second arm having a second passage that is in angled orientation to the header passage;
wherein the header hub is attached to the proximal end of the main hub in a releasably locked configuration, and the header hub is capable of being unlocked from the main hub by the releasably locked configuration, and being completely detached from the main hub so that an intravascular instrument being unable to pass through the header passage is directly inserted into the main hub in preforming a medical procedure, wherein the size of the intravascular instrument being unable to pass through the header passage is larger than the sizes of the first passage and the second passage.
