A delivery system can be provided with an ability to change its configurations to achieve both access to target anatomy and treatment thereof. Such treatments can include directing interventional devices around an occlusion. By providing different functionality at different stages, the need to exchange and replace tools at different stages can be reduced or eliminated. Accordingly, such operations can be completed more rapidly, efficiently, and safely.

Disclosed herein is an automated urinary output monitoring system including urine collection assembly that includes a first drainage tube coupled between a urinary catheter and an interim container, and a second drainage coupled between the interim container and a final container. A scale measures the weight of urine collected in the final container and a display depicts the volume of urine collected in the final container. A vacuum pump can be coupled with the final container to draw urine from the interim container into the final container, and an air vent can isolate the patient from the vacuum within the final container. The system can be configured to wirelessly transmit urine volume data to an external computing device. A gyroscope can be coupled with the scale to determine the orientation of the scale. Logic of the system can calculate urine volume and correlate with the time of day.

A biopsy needle has a central axis and includes one or more sensing regions, each sensing region formed by a plurality of sensing optical fibers located over a particular extent of said central axis and inside the outer shell of the needle. The sensing optical fibers are coupled to a wavelength interrogator. A steerable catheter has a central axis and outer shell, the outer shell coupled to a plurality of optical fibers in sensing regions and actuation regions, the sensing regions formed over particular extents of the central axis by bonding gratings to the inner surface of the outer shell, and the actuation regions formed by coupling optical energy into shape memory alloys bonded to the outer shell.

The distal tip structure of a rapidly insertable central catheter (RICC) can be required to perform different functions from that of the remaining, multi-luminal section, of the RICC catheter. As such, the catheter body can be formed of a first material and the distal tip structure can be formed of a second material. Forming the RICC requires joining these two materials while maintaining a smooth abluminal surface. A bifurcated plug including a second material can be placed within a first lumen or second lumen of the catheter body. A mandrel can be placed within a third lumen. The assembly can then be placed within a die to plastically deform the bifurcated plug into a distal tip structure. Advantageously, only a single structure is required to plug the lumen and form the distal tip structure, reducing complexity and associated costs.

Discussed herein are various embodiments related to a catheter assembly. The catheter assembly can include a catheter body extending between a proximal portion and a distal portion. The catheter body can include a sleeve and a hypotube, connected by at least one bond site, and separated by a floating gap. The hypotube can include at least one flow opening extending from the hypotube lumen to a stagnation zone, configured to permit flow between the stagnation zone and the hypotube lumen.

An intravascular access system for facilitation of intraluminal medical procedures within the neurovasculature through an access sheath. The system includes an aspiration or support catheter having a flexible, distal luminal portion having an inner diameter defining a lumen extending between a proximal opening at a proximal end of the luminal portion and a distal opening at a distal end of the luminal portion. The catheter has a rigid spine coupled to at least the proximal end of the luminal portion and extending proximally therefrom. The system includes a dilator having a flexible, distal dilator portion sized to be received within the lumen of the luminal portion. Associated systems, devices, and methods of use are also described.

A gastric jejunal (GJ) feeding tube device for GJ feeding of an infant or child is provided. The device comprises a GJ button comprising a GJ button body, a gastric port, a jejunal port, a gastric channel, and a jejunal channel. The device also comprises a multi-lumen tube comprising a multi-lumen tube body, a multi-lumen tube proximal end, and a multi-lumen tube distal end. The device also comprises a jejunal tube comprising a jejunal tube body, a jejunal tube proximal end, a jejunal tube distal end, a spring, and a ring. The spring provides a kink-resistant feature. The ring is positioned at the jejunal tube proximal end. The jejunal tube and the GJ button are operatively connected at the ring and the mating surface by radial compression. The ring has a higher durometer than the jejunal tube body and an outer diameter that does not substantially decrease distally.

In some embodiments, a catheter device may include a catheter including a proximal end and a distal end. The catheter device may further include a connector coupled to the proximal end of the catheter. The connector may include a base having a recess configured to receive the distal end of the catheter and may include a hinged portion configured to couple to the base to clamp the catheter within the recess.

An aspiration clot retrieval catheter to have profiled guidewire for deliverability that transitions at a proximal joint to a distal tubular section with a lumen for directing aspiration and facilitating the smooth passage of other products in performing mechanical thrombectomy procedures. The joint can have a low-profile proximal strut formed integrally with the distal tubular section and configured to interlock with a distal portion of the guidewire so that there is a smooth transition of stiffness between the guidewire and the tubular portion of the catheter to improve trackability and decrease the likelihood of kinking. The distal tubular section of the proximal joint can also have features to tailor flexibility. The tubular section can be configured to push radially outward to form a seal with an outer catheter to optimize aspiration transmission to the distal mouth of the aspiration clot retrieval catheter.

A catheter includes an elongate shaft, an electrode assembly, a connective stem, a coupler, a first magnetic position sensor, and a second magnetic position sensor. The electrode assembly includes microelectrodes. The connective stem includes a first connective stem member and a second connective stem member. The connective stem defines a first sensor receptacle and a second sensor receptacle in an exterior surface of the connective stem. The coupler is configured for coupling with the connective stem. The first magnetic position sensor is disposed in the first sensor receptacle and elongated along a first sensor longitudinal axis. The second magnetic position sensor disposed in the second sensor receptacle and elongated along a second sensor longitudinal axis that is not parallel to the first sensor longitudinal axis.
