Abstract: A surgical method treats infections on a lead positioned at least partially within a patient's body. The surgical method includes uncoupling the lead from a pulse generator. The lead is then coupled to an ultrasound wave generator. Ultrasound waves are propagated from the ultrasound wave generator through the lead. Systems are disclosed.

Abstract: Catheters with at least two curved portions near their distal ends are provided. The lengths and/or curvatures of the curved portions are selected so that a catheter can be advanced through a brachiocephalic or left subclavian artery (BCA or LSC) to access the ascending or descending aorta (AA or DA), withdrawn therefrom, and simply rotated to access the AA or DA. Hence, the catheters provide access to both the AA and DA through the BCA or LSC without any need to withdraw the catheter from the BCA or LSC, e.g., so a second catheter can be exchanged for it. The catheter can further be advanced through the DA into the abdominal aorta and rotated to access branch arteries including the vessels of the lower extremities. The catheters are usable for flush aortography, arteriography, and intravascular pressure measurements, and can be introduced to the BCA or LSC via radial artery access.

Abstract: Methods for treating hydrocephalus using a shunt, the shunt having one or more CSF intake openings in a distal portion, a valve disposed in a proximal portion of the shunt, and a lumen extending between the one or more CSF intake openings and the valve, the method comprises deploying the shunt in a body of a patient so that the distal portion of the shunt is at least partially disposed within a CP angle cistern, a body of the shunt is at least partially disposed within an IPS of the patient, and the proximal portion of the shunt is at least partially disposed within or proximate to a JV of the patient, wherein, after deployment of the shunt, CSF flows from the CP angle cistern to the JV via the shunt lumen at a flow rate in a range of 5 ml per hour to 15 ml per hour.

Abstract: A catheter includes a rolling membrane defining an inner volume that can be pressurized. The rolling membrane is configured to roll out in a longitudinal direction (D) into a rolled-out state. An inner shaft is attached to the rolling membrane. The membrane can roll out in a longitudinal direction along a vessel of a patient.

Abstract: A vascular closure device is configured to seal a puncture in an artery or vein. The vascular closure device includes a deployment assembly having a proximal end and a distal end opposite the proximal end, a suture carried by the deployment assembly, and a footplate carried by the deployment assembly and coupled to the suture. The footplate is configured to exit the distal end of the deployment assembly for deployment in the puncture. The vascular closure device includes a retraction assembly coupled to the footplate, the retraction assembly configured to, after deployment of the footplate, retract the footplate in a proximal direction.

Abstract: A guidewire system includes an elongated wire configured for insertion into a luminal space, such as the vasculature, of a body. The wire is conductive and configured to conduct electrical signals. One or more sensors are coupled to a distal section of the wire and configured to send and receive the electrical signals via the wire. The wire through which the one or more sensors are coupled is the only wire through which the one or more sensors send and receive the electrical signals.
