An introducer for insertion of a medical device into a patient's vasculature includes an elongate introducer body, a hub, and a hemostatic valve. The elongate introducer body includes a longitudinal axis, a proximal region, a distal region, and an inner lumen. The hub is coupled to the proximal region of the introducer body. The hemostatic valve is disposed within the hub and forms a liquid-tight seal across the inner lumen. The introducer includes a guide configured to guide an object towards the center of the valve during insertion of the object.

Hemostatic valve for medical device introducer

A system for providing vascular access in a patient's body may comprise at least one hemostatic valve () and at least one clamp () to be used with a vascular graft (). The vascular graft () comprises a tubular body having a proximal end (A) and a distal end (B), the proximal end (A) being configured to be attached to a vessel in a patient's body. The at least one valve () is configured to be attached to the distal end (B) of the graft's tubular body and comprises a housing () including a flexible membrane () that allows a medical device () to be inserted through the membrane () into said vascular graft (). The valve () further comprises an introducer sheath () configured to be inserted into the distal end (B) of the graft's tubular body. The at least one clamp () is configured to be disposed around the graft's tubular body and has a first configuration that allows insertion of the valve's introducer sheath () into the distal end (B) of the graft's tubular body and a second configuration that allows clamping of the graft () against the valve's introducer sheath (), when inserted in the graft's tubular body.

Vascular access

A cannula supporting a percutaneous pump can include a proximal section with a first flexural modulus. The cannula can include one or more distal sections with a flexural modulus that is different than the first flexural modulus. The material and its arrangement along the length of the cannula can be selected so as to influence bending properties. This can, for example, allow efficient positioning of the cannula in a desired location without displacing the guidewire.
