The device includes a sheath portion having a proximal end and a distal end and a plurality of stabilization wires. The sheath portion includes a primary lumen that extends from the proximal end to the distal end and a plurality of secondary lumens that extend from the proximal end to the distal end. The stabilization wires are configured to be slidably received within the secondary lumens. The length of the stabilization wires is greater than the length of the secondary lumens.

A system for determining orientation of a distal end of a catheter. The system includes a radial ultrasound system configured to generate images based on data received from a radial ultrasound probe. The system also includes a display device to present the generated images, a medical device, and a catheter system. The catheter system includes a flexible shaft having a first lumen configured to receive the radial ultrasound probe and a second lumen configured to receive the medical device, a cap portion having a longitudinal axis, and at least one orientation pin. The cap portion includes a third lumen configured to align with the first lumen, a fourth lumen configured to align with the second lumen, an exit port, and a ramp disposed between the fourth lumen and the exit port.

Devices for preventing and/or otherwise inhibiting biofilm formation include a lumen and/or a cavity coupled with a wall configured for holding oils, which leach through the wall of the devices to a surface, the oils at the surface creating a smooth surface coating.

The present disclosure relates to an intravascular catheter with sensor systems that can measure intravascular pressure using MEMS sensors. Devices of the present disclosure can also be used to administer intravenous therapies, such as drug delivery or hemodialysis. Exemplary devices can be equipped with multiple MEMS sensors to measure pressure in multiple locations throughout the cardiovascular system. The intravascular catheter can communicate with a receiver and monitor to display sensor data.

In some examples, a catheter includes an elongated body comprising proximal and distal portions. The distal portion of the elongated body comprises an inner liner that includes a proximal liner section and a distal liner section that include different materials, and an outer jacket positioned over the inner liner. The distal liner section has a first hardness and the proximal liner section has a second hardness, where the first hardness is less than the second hardness.

A system for determining orientation of a distal end of a catheter. The system includes a flexible shaft having a first lumen, a second lumen, a third lumen, a fourth lumen, a first orientation pin and a second orientation pin. The first orientation pin is received within the third lumen and the second orientation pin is received within the fourth lumen. The flexible shaft includes a cross-sectional dimension and the third lumen and the fourth lumen include longitudinal axes that are located on the same half of the cross-sectional dimension of the catheter. The second lumen includes an exit port for exposing at least a portion of the second lumen of the cap portion and a ramp. A distal end of the flexible shaft is made of material permeable to ultrasound signals and the orientation pins include one or more materials that are non-permeable to ultrasound signals.

Steering engagement catheter devices, systems, and methods of using the same for accessing a tissue, including internal and external tissues of a heart, are disclosed. In at least one embodiment, a steering engagement catheter is provided, comprising an elongated tube having a proximal end, a distal end, and a first wall positioned circumferentially along a length of the elongated tube, the elongated tube configured such that a delivery catheter is capable of at least partial insertion into the elongated tube, at least one steering wire having a proximal end and a distal end, the distal end of the at least one steering wire coupled to the first wall of the elongated tube at or near the distal end of the elongated tube, and a controller operably coupled to the at least one steering wire at or near the proximal end of the at least one steering wire.
