Abstract
A system for insertion into a vasculature of a patient is disclosed. The system utilizes a primary tubular sheath body coupled to a distal portion of an intermediate tubular sheath body, and a hub coupled to a proximal portion of the intermediate tubular sheath. The hub may be couplable to a dilator via an interaction between a dilator cap and the hub, and the hub may contain a hemostatic valve with a foam member having one or more visibly identifiably regions.
Claims15
A device for insertion into a vasculature of a patient, the device comprising:
- a primary tubular sheath body comprising a first material, the primary tubular sheath body extending from a proximal end to a distal end;
- an intermediate tubular sheath body comprising a second material, the intermediate tubular sheath body extending from a proximal end to a distal end, the distal end of the intermediate tubular sheath body connected to the proximal end of the primary tubular sheath body;
- and
- a hub comprising a third material, the hub connected to a proximal portion of the intermediate tubular sheath body and separated from the primary tubular sheath body by the intermediate tubular sheath body,
- wherein the first material, second material, and third material are configured such that a theoretical interfacial bonding strength between the first and second material, and a theoretical interfacial bonding strength between the third material and the second material, are both greater than a theoretical interfacial bonding strength between the first material and the third material.
