Disclosed are introducer components, assemblies, and methods. For example, an introducer assembly can include a fluidly connected syringe and needle. The needle can include a needle shaft and a needle hub over a proximal portion of the needle shaft. The needle hub can include a port and a valve disposed in the port. The port can be in a side of the needle hub proximal of a proximal end of the needle shaft. The valve can be configured to form a fluid-tight seal around an elongate medical device such as an access guidewire when passed through the port and into a needle-hub lumen of the needle hub. Such an access guidewire can be disposed in the introducer assembly just proximal of a needle tip of the needle. In this way, the access guidewire can be immediately advanced into a blood-vessel lumen upon establishing a needle tract thereto with the needle.

A surgical port includes a first end, a second end opposite the first end, and a longitudinal axis extending through the first end and the second end. An outer sidewall extends between the first end and the second end. First and second channels extend through the port from the first end to the second end. A first electrically conductive portion extends from the first channel to the outer sidewall, and a second electrically conductive portion extends from the second channel to the outer sidewall. The first electrically conductive portion provides a first electrically conductive path between the first channel and the outer sidewall and the second electrically conductive portion provides a second electrically conductive path the second channel and the outer sidewall. The second electrically conductive path is separate from the first electrically conductive path. Devices and methods relate to surgical ports.

According to aspects disclosed herein, an infusion lead assembly may include a housing including a needle receptacle, a housing lumen, a pin receptacle, and a housing conductive trace; a connector including an connector needle, an internal lumen, a metal pin, and a connector conductive trace, and an infusion lead body including an infusion lumen, an exit port, an internal wire, and a distal electrode. The infusion lead assembly may form an electrical path to transmit electrical signals across the connector conductive trace, the metal pin, the housing conductive trace, the internal wire, and the distal electrode. The infusion lead assembly may form a fluid path to transmit fluid across the internal lumen, the connector needle, the infusion lumen, and the exit port.

A catheter assembly may include a catheter adapter, which may include a distal end, a proximal end, a lumen extending through the distal end of the catheter adapter and the proximal end of the catheter adapter, and a side port disposed between the distal end of the catheter adapter and the proximal end of the catheter adapter. The catheter assembly may include a catheter extending distally from the distal end of the catheter adapter. The catheter assembly may include a valve disposed within the lumen. The catheter assembly may include a retainer element configured to secure the annular valve within the lumen. The retainer element may be disposed within the lumen proximal to a proximal end of the annular valve.

A low-profile access port for subcutaneous implantation within a patient. The access port can include a set of receiving cups which can be placed in fluid communication with a catheter. The set of receiving cups can provide a greater skin surface with which to access the port to avoid repeated penetrations at a single locus, such as during consecutive dialysis treatments. The access port can alternatively include needle penetrable arms or elongate chambers that also have a slim, low profile. The access port can include a needle guide to direct subsequent needle access to different insertion points to permit healing at the previous insertion points. The access port can be formed of a modular construction with a first conduit, a second conduit, and an outer shell. The outer shell can include a proximal portion and a distal portion. The access port can include a stem assembly and a locking member.

The present invention relates to novel surgical drains and associated methods and systems. Specifically, the present invention includes a surgical drain with at least two ports. A first port drains lymphatic fluid from a subject for collection and analysis. The second port functions to introduce a therapeutic into the subject.

An implantable cranial medical device includes a first fluid flow path, a second fluid flow path, and upper flange portion, and a lower portion. The upper flange portion is configured to rest on a skull of a subject about a burr hole. The lower portion is configured to be placed within the burr hole. The first fluid flow path may extend from a first opening in the upper flange portion to a first opening in the lower portion. The second fluid flow path may extend from a second opening in the upper flange portion to a second opening in the lower portion.

A surgical access assembly and method of use is disclosed. The surgical access assembly comprises an outer sheath and an obturator. The outer sheath and obturator are configured to be delivered to an area of interest within the brain. Either the outer sheath or the obturator may be configured to operate with a navigational system to track the location of either within the brain. Once positioned at a desired location, the obturator is removed, leaving a distal end of the outer sheath adjacent an area of interest, and creating a working corridor. Interrogation of the area of interest may be performed to evaluate a disorder and/or abnormality, as well as evaluate treatment regimes. Interventional devices may also be introduced to the area of interest, as well as a variety of treatments.

The invention provides a blood pump for use with an intravascular ventricular assist system (iVAS), as well as a method for utilizing the blood pump to treat heart failure.
