Abstract: An embolic agent and a piezoelectric substance are mixed together. The mixture can be delivered to a tumor or other object by a non-invasive method. The embolic agent prevents movement of the piezoelectric substance from the target location. Subsequent impulses applied to the target location cause ablation of the surrounding area due to the piezoelectric effect of the particles, promoting highly accurate and precise ablation without the need for more invasive procedures.

Abstract: Embodiments relate to a system for providing a first fluid and a second fluid. The system includes a catheter hub, a flexible cover, and a catheter. The flexible cover is configured to attach to the catheter hub and provide a seal therewith. The catheter is configured to be at least partially arranged within the catheter hub and the flexible cover and pass through the seal. The catheter includes a primary lumen and a secondary lumen, wherein the primary lumen is configured to provide the first fluid at a distal end of the catheter, and the secondary lumen is configured to provide the second fluid at each of a plurality of apertures arranged on an outer radial wall of the catheter.

Abstract: Embodiments relate to multi-focal intravascular pressure catheters and related systems and methods. In an embodiment, a catheter comprises a plurality of pressure sensors spaced apart along at least a portion of the catheter. Each of the plurality of pressure sensors can comprise a pressure membrane arranged over an aperture in the catheter. In an embodiment, the pressure membrane can comprise carbon nanotubes, silver or gold nanoparticles, or another suitable material that can provide a signal in response to a mechanical change (e.g., deformation or flexing of the pressure membrane) to indicate a pressure or change in pressure. Signals from the plurality of pressure sensors can be communicated to an electrical interface which can calibrate or convert the signals into a visual indication of the pressure at any one of the plurality of pressure sensors as well as pressure gradients between various ones of the plurality of pressure sensors.

Abstract: A vascular graft includes deformable sleeves that include an electrical component. The electrical component can be variable-resistance or piezoelectric, in embodiments, such that deformation of the sleeves due to pressure changes create or modify an electrical signal. A transponder can then transmit information relating to the pressure inside and outside of the vascular graft.

Abstract: An extraventricular drain system can include a catheter. The catheter can have a shaft including a proximal end and a distal end, a lumen extended along a length of the catheter, and a drain located on the shaft. The drain can be fluidly coupled with the lumen. In an example, an electrode can be located along the shaft at an axial location. A reference contact can be located on the shaft at an axial location further from the distal end than the electrode. The electrode and the reference contact can be configured for electrical communication with a processing unit. In a further example, a first pressure port and a second pressure port can be located at the distal end and have different respective axial locations and respective radial locations. The first and second pressure ports can be in fluid communication with a first and second pressure sensors respectively.

Abstract: A nodule localization system includes a localization structure. The localization structure is arranged to extend from a nodule to a suture, and the entire coil can be located in the lung such that the suture extends through the pleural space. During normal respiration or other movement, the suture will move to be positioned mostly or entirely in the pleural space such that a surgeon can follow the suture to the coil and resect the nodule.

Abstract: A multi-lumen catheter defining a longitudinal axis includes an inflation lumen, a plug lumen, and a microcatheter lumen, each defined by the catheter and extending substantially parallel to the longitudinal axis. The inflation lumen defines an inlet aperture and an outlet aperture and is configured to provide a fluidic connection from the inlet aperture of the inflation lumen to a balloon. The plug lumen defines an inlet aperture and an outlet aperture and is configured to deliver a plug. The microcatheter lumen defines an inlet aperture and an outlet aperture and is configured to house a microcatheter.
