Abstract: A system for aerating a marker material. The system includes a first container, a second container, and an aeration connector. The aeration connector includes a body and a screen disk disposed within the body. The first container is in communication with the second container via the aeration connector. The screen disk of the aeration connector is configured to aerate a marker material as the marker material is repeatedly passed between the first container and the second container.

Abstract: Embodiments are directed to radiopaque implantable structures (e.g., stents) formed of cobalt-based alloys that comprise cobalt, chromium, tungsten, and nickel, and methods for their manufacture. Tungsten is present above its solubility limit (about 15%) at ambient temperature, but is still only present as a super-saturated, primarily single-phase material exhibiting an FCC microcrystalline structure.

Abstract: This disclosure is related to methods, devices, assemblies, and system for transbronchial ablation of a lung tumor. Aspects of the disclosure are included as follows. A radiofrequency (RF) ablation catheter which is configured to heat a passageway filled with a liquid metal, the ablation catheter comprises a flexible shaft having a proximal end and a distal end, the flexible shaft having a fluid channel configured to instill the liquid metal into the passageway. The ablation catheter further comprises an inflatable balloon mounted on the flexible shaft wherein a portion of the flexible shaft that is distal to the balloon is defined as a distal segment of the flexible shaft, the balloon configured to obstruct the passageway. The ablation catheter comprises an RF conductor located on the distal segment configured for connecting RF energy to the liquid metal thereby heating the passageway.

Abstract: Various exemplary surgical adjuncts with medicants affected by activator materials are provided. In general, an adjunct is provided with at least one medicant that is configured to be activated by an activator material. The adjunct can be delivered to a tissue of a patient, where the adjunct can be implanted. Various activator materials can be configured to activate the at least one medicant retained by the adjunct, the activation causing any one or more of a variety of actions. For example, the at least one medicant can be activated so as to yield at least one of a signal and/or an effect on the adjunct.

Abstract: An embodiment includes a process for treating an abdominal aortic aneurysm (AAA) endoleak with a shape memory polymer (SMP) foam device. First, a bifurcated stent graft is placed within the aneurysm while a micro guidewire is positioned within the aneurysm for future catheter access. Second, after placing the iliac graft extension, a catheter is introduced over wire to deliver embolic foams. Third, embolic foams expand and conform to the aneurysm wall. Fourth, embolic foams create a stable thrombus to prevent endoleak formation by isolating peripheral vessels from the aneurysm volume.

Abstract: The present disclosure relates to guidewire devices having shapeable tips and effective torquability. A guidewire device includes a core having a proximal section and a tapered distal section. A tube structure is coupled to the core such that the tapered distal section of the core extends into and distally beyond the tube structure. The portion of the core extending distally beyond the tube forms a shapeable tip. One or more coils also extend distally beyond the tube. The tip is configured to reduce the tendency of resilient forces from the tube structure to disrupt a customized shape of the tip.

Abstract: A method and system are used to enhance a marker material to include a plurality of air bubbles. The method of manufacturing a marker includes enhancing a marker material to include a plurality of air bubbles using at least a first EFD and a second EFD. The method may include cycling repeatedly through a transfer process between a first container and a second container. A system for enhancing a marker material includes a transfer apparatus configured to receive a marker material and a selected amount of air. The system comprises a first EFD coupled to a first end of the transfer apparatus and a second EFD coupled to a second end of the transfer apparatus.
