Abstract
Methods and apparatus for locating a device with respect to a blood vessel. An expandable or extrudable member transverse to the device locates an internal surface of a proximal wall of the blood vessel. A typical application of such methods and apparatus is providing relative position between a femoral arterial wall and a closure device axis. Predetermined location positions are recognized as a positive stop transmitted to a physician via tactile feedback.
Claims33
A vascular puncture locator, comprising:
- a tubular member configured as an introducer and adapted for partial insertion into a blood vessel, the tubular member having first and second ends, a sidewall defining an exterior surface, and a central inner bore that extends from the first end to the second end and defines an interior surface, the inner bore being receptive of vascular instruments and closure devices;
- a first side port disposed in the sidewall of the tubular member and extending from the inner bore through the sidewall to the exterior surface of the tubular member;
- a first extrudable member disposed inside the inner bore proximal of the first side port and directly affixed at a distal end thereof to the interior surface at the first end of the tubular member;
- wherein the first extrudable member is predisposed to exit through the first side port in a lateral direction from the inner bore to the exterior surface.

A vascular insertion apparatus, comprising:
- a tubular member configured as an introducer and adapted for insertion into a blood vessel, the tubular member having first and second ends, a sidewall that defines an exterior surface, and a central inner bore that extends from the first end to the second end and defines an interior surface, the inner bore being receptive of vascular instruments and closure devices;
- a first side port disposed in the sidewall of the tubular member and extending from the inner bore through the sidewall to the exterior surface of the tubular member;
- a first flexible member disposed inside the inner bore proximal of the first side port and extending across the first side port, the first flexible member being affixed to the interior surface at a location distal of the first side port;
- wherein compression of the first flexible member effects extrusion thereof through the first side port in a lateral direction from the inner bore to the exterior surface.

A method of making a vascular insertion apparatus, comprising:
- providing a tubular body having first and second ends, a sidewall defining an exterior surface, and a central inner bore that extends from the first end to the second end and defines an interior surface, the inner bore being receptive of vascular instruments and closure devices;
- disposing an extrudable member into the inner bore of the tubular body;
- rigidly affixing a distal end of the extrudable member to the interior surface of the tubular body within the inner bore;
- providing a first side port in the tubular body receptive of extrudable member, the first side port extending from the inner bore interior through the sidewall to the exterior surface of the tubular body, the extrudable member positioned inside the inner bore proximal of the first side port and being extrudable through the first side port in a lateral direction from the inner bore to the exterior surface.

A method of locating a vascular puncture, comprising:
- inserting a tubular member into a vessel, the tubular member being configured as an introducer and including a first end, a second end, a sidewall defining an exterior surface, a central inner bore extending from the first end to the second end and defining an interior surface, and a first side port defined in the sidewall, the inner bore being receptive of vascular instruments and closure devices;
- extruding a first locating petal of an extrudable member transversely through the first side port in the tubular member from the inner bore to the exterior surface, the first side port extending from the inner bore defined in the tubular member through the sidewall to the exterior surface of the tubular member, a portion of the extrudable member positioned within the inner bore proximal of the first side port and being affixed to the interior surface;
- retracting the tubular member;
- contacting an inner wall of the vessel with the first locating petal.
