An intravascular device, such as a stylet or catheter, having a flexible, atraumatic tip is disclosed. The intravascular device includes an elongate member having a proximal end, a distal end, and an inner lumen extending between the proximal end and the distal end; a ring electrode disposed at the distal end of the elongate member; an ultrasound sensor disposed at a distal end of the ring electrode; and a first electrical conductor configured to convey an electrocardiogram signal from the ring electrode to a processor. The first electrical conductor may comprise a tapered distal segment or a braided segment.

Intravascular sensing devices having flexible tip structure

An assembly is provided for accessing a superior vena cava of a patient without visualization of a vasculature of the patient. A stylet has an elongated body including a core wire disposed within a tubular body, the core wire having a pre-formed shape in a first state and a straightened shape in a second state. A first portion of the core wire has a substantially straight shape in the first state. A second portion of the core wire has a first pre-formed bend in the first state. A third portion of the core wire has a substantially straight shape in the first state. A fourth portion of the core wire has a second pre-formed bend in the first state. A fifth portion of the core wire has a substantially straight shape in the first state and includes a narrow segment that increases deflection of the distal tip.

Stylet with improved threadability

A method for inserting at least a portion of a dilator and sheath assembly into a patient and for removing the dilator from the patient is disclosed. Initially, the dilator and sheath assembly is received. The dilator includes a radially enlarged dilator bump. At least the distal ends of the dilator and the sheath are inserted in an incision in the patient. A vector force is exerted to the dilator and sheath assembly to push the dilator and sheath assembly further within the patient. The dilator hub is decoupled from the sheath hub. The dilator is removed from the patient through the sheath, where the dilator bump radially stretches at least the circumferentially continuous sheath distal end during removal of the dilator from the patient.

Bumped dilator tip

The disclosure provides a dilator with a tip that has a bump, an assembly comprising the dilator and a sheath, and methods of use, where the bump on the tip is configured to reduce or minimize damage to the sheath, and to prevent trauma to a patient during insertion or removal.
