Apparatuses and methods for direct carotid intervention

A stent delivery device comprising:

• an outer sheath including an elongated tubular member having a distal end and a proximal end and defining a lumen;
• a stent located within the outer sheath, the stent making frictional contact with and exerting an outward force on an inner surface of the outer sheath;
• a first wire located coaxially within the lumen and the stent, the first wire having a distal end extending distally of the distal end of the outer sheath, and a proximal end, extending proximally of the proximal end of the outer sheath;
• and
• a filter disposed within the outer sheath and coupled to the first wire and distally of the stent, wherein the outer sheath is configured to be withdrawn proximally to deploy the stent and the filter.

A method of deploying a stent, the method comprising:

• inserting a stent delivery device into a blood vessel, the stent delivery device including:
• an outer sheath including an elongated tubular member having a distal end and a proximal end and defining a lumen;
• a stent located within the outer sheath, the stent making frictional contact with and exerting an outward force on an inner surface of the outer sheath;
• a first wire located coaxially within the lumen and the stent, the first wire having a distal end extending distally of the distal end of the outer sheath, and a proximal end, extending proximally of the proximal end of the outer sheath;
• a filter disposed within the outer sheath and coupled to the first wire and distally of the stent;
• and
• a distal tip detachably coupled to the distal end of the outer sheath separating the outer sheath from the distal tip;
• withdrawing the outer sheath proximally from the blood vessel to deploy the stent and the filter;
• withdrawing the distal tip proximally from the blood vessel to collapse the filter;
• and
• withdrawing the filter and the distal tip through the deployed stent.

A stent delivery device comprising:

• an outer sheath including an elongated tubular member having a distal end and a proximal end and defining a lumen;
• a stent located within the outer sheath, the stent making frictional contact with and exerting an outward force on an inner surface of the outer sheath;
• an inner catheter located coaxially within the lumen and the stent, the inner catheter having a distal end extending distally of the distal end of the outer sheath, and a proximal end;
• and
• a filter disposed within the outer sheath and coupled to the inner catheter and distally of the stent, wherein the outer sheath is configured to be withdrawn proximally to deploy the stent and the filter.

A catheter comprising:

• an outer sheath including an elongated tubular member having a distal end and a proximal end and defining a lumen;
• a distal tip coupled to the distal end of the outer sheath insertable through a puncture in a blood vessel;
• and
• a plug releasably coupled to the distal tip and positionable by the distal tip within the puncture, the plug including a plate portion for sealing the puncture and an attachment portion for securing the plug to the blood vessel.

A blood leak detection system comprising:

• a needle sensor device insertable near a sealed vessel puncture, the needle sensor device including at least one of an optical, a mechanical, or an electrical sensor for detecting a blood leak;
• and
• an interrogator device coupled to the needle sensor and configured to:
• generate a sensor signal for measuring an electrical, mechanical, or an optical property of tissue affected by the blood leak;
• receive a measurement signal from the needle sensor,
• compare the measurement signal to a threshold indicative of the blood leak;
• and
• output an alert in response to the measurement signal being outside the threshold.
