Vascular introducer hubs for reducing blood leakage

A vascular introducer hub comprising:

• a body that includes a proximal end, a distal end, and a lumen defined therethrough;
• and
• first and second seals disposed within the body, the first seal comprising a first polymeric material, the second seal comprising a second polymeric material;
• the first and second polymeric materials have different durometers.

A vascular introducer device comprising:

• an elongate shaft including a proximal end, a distal end, and a lumen therethrough, the lumen sized to receive a catheter device, the distal end defining an opening configured to allow the catheter device to pass through;
• and
• a hub coupled to the proximal end of the elongate shaft, the hub comprising:
• a body that includes a proximal end, a distal end, and a lumen defined therethrough;
• and
• first and second seals disposed within the body, the first seal comprising a first polymeric material, the second seal comprising a second polymeric material;
• the first and second polymeric materials of the hub having different durometers.

A method of introducing a catheter into a patient, the method comprising:

• obtaining an introducer;
• inserting the introducer into a patient's vasculature;
• inserting a catheter into the introducer, the inserting comprising;
• and
• opening a proximal seal of an introducer hub by rotating a proximal actuator of the introducer hub;
• inserting the catheter into a proximal end of the introducer hub;
• advancing the catheter into a lumen of the introducer hub;
• closing the proximal seal over the catheter such that the catheter is slidably moveable through the proximal seal and bodily fluids are substantially contained within the lumen of the hub by the proximal seal;
• and
• opening a distal seal by rotating a distal actuator and advancing the catheter through the distal seal.
