Abstract: Medical systems for depositing fibrin on a medical device ex vivo are disclosed herein. According to some embodiments, the present technology includes a medical system comprising a vascular implant and a package defining a reservoir configured to receive the vascular implant and a volume of blood. The package can include an electrode disposed within the reservoir. The medical system can further include a current generator configured to be electrically coupled to the electrode. Activation of the current generator while the vascular implant and blood are present in the reservoir can cause current to flow through the blood and vascular implant, thereby applying an electrical charge to the vascular implant.

Abstract: A system for treatment of intracranial stenosis can include a catheter having a lumen, and an elongate member extending through the lumen. A distal pressure sensor is coupled to a distal end portion of the elongate member and is configured to obtain blood pressure parameters to characterize blood flow at a treatment site before and after treatment. A stent is disposed within the catheter lumen in a radially constrained configuration. The stent surrounds the elongate member such that the distal end portion of the elongate member is disposed distal to a distal end of the stent. The stent is configured to radially expand into apposition with the blood vessel to increase blood flow at the treatment site when released from the catheter.

Abstract: Systems, methods, and devices having improved conformal properties for biomedical signal measurement are disclosed. A device can have a first polymer substrate coupled to a conductive layer forming a conductive trace electrically coupled to a conductive pad exposed via an opening. The device can have a second polymer substrate forming a first cavity between the first polymer substrate and the second polymer substrate. The device can have a first inlet portion that receives a fluid that expands the first cavity causing the device to conform to an anatomical structure. The structure can be an atrium, such as the left atrium, of the heart of a patient. The device can conform to the walls of the tissue structure, and the conductive pad exposed via the opening can detect a signal from the wall of the tissue structure. The signal can be provided to an external measurement device for processing.
