A method may include intravenously directing first bubbles into a patient's venous circulatory system and to a right side of the patient's heart. The first bubbles may have sizes that fall within a first range. The method may further include monitoring the patient's heart, with ultrasound imaging, to detect presence of the first bubbles on a left side of the patient's heart. Upon detecting the first bubbles on the left side of the patient's heart, the method may further include intravenously directing second bubbles into the patient's venous circulatory system and to the right side of the patient's heart. The second bubbles may have sizes that fall within a second range that is different than the first range. Upon detecting the second bubbles on the left side of the patient's heart, the method may further include initiating treatment to minimize risk of stroke in the patient.

Characterization of cardiac shunts with bubbles

In some embodiments, a method includes releasably attaching an image capture assembly to a distal portion of a TEE device. Next, the TEE device coupled to the image capture assembly is inserted into an oral cavity of the patient. With the image capture assembly releasably attached to the distal portion of the TEE device, image data of an esophagus of the patient captured by the image capture assembly is displayed. While viewing the display of image data, the TEE device coupled to the image capture assembly can be moved within the esophagus. With both the TEE device and the image capture assembly disposed within the esophagus, the image capture assembly is detached from the TEE device. With the image capture assembly detached from the TEE device, and with the TEE device disposed at least in part within the esophagus, the image capture assembly is removed from the patient.

A reinforced medical electrical lead for neurological applications has a reinforced construction for resisting the detachment of electrodes and lead connection terminals, thereby improving the robustness of the lead and extending the life of the lead by reducing the likelihood that a further surgical procedure will be required to remove the lead for repair or replacement thereof. The present reinforced lead construction maintains the integrity of the electrical connection between the conductor and the respective electrode and lead connection terminal by incorporating several reinforcing features in the lead construction in contrast to conventional lead constructions where it is possible to pull the electrodes and lead connection terminals away from their contact points with relatively little force.

Reinforced sensing and stimulation leads and use in detection systems

An implantable neurostimulation electrode assembly comprises a first electrode unit and a second electrode unit configured to be arranged in a side-by-side configuration. The first electrode unit includes a dielectric first paddle, a plurality of first electrodes carried by the first paddle, and a guideline. The guideline has a distal section affixed to the first paddle and a proximal section having a length configured to extend externally of a patient. The second electrode unit has a dielectric second paddle and a plurality of second electrodes carried by the second paddle. The second paddle is configured to travel along the guideline and contact the first paddle in the side-by-side configuration. As a result, the first and second electrode units of this embodiment can be passed percutaneously through the same percutaneous entry hole and assembled in vivo at the stimulation site to form a larger paddle-type electrode array without surgical implantation.

Implantable neural stimulation electrode assemblies and methods for stimulating spinal neural sites

The present application includes treatment systems having delivery-activated inflatable members, and associated systems and methods for treating the spinal cord and other tissues. A treatment system in accordance with one embodiment includes a lead body having an opening, an inner surface position around the opening, and an inflatable member carried by the lead body, with at least one of the inflatable member and the lead body including a frangible portion accessible from the opening. The inflatable member can have an expandable interior volume bounded at least in part by the frangible portion. The system can further include a delivery device received in the opening of the lead body and positioned to open a passage through the frangible portions between the interior volume of the inflatable member and the opening of the lead body when the delivery device is removed from the opening of the lead body.

Medical electrical lead systems and related methods are described. The lead systems may be configured to be at least partially implanted in neural tissue of a subject, such as a brain of a subject. Some variations of the lead systems may comprise a lead body, an electrode connected to the lead body, and a bioactive agent. The electrode and/or lead body may comprise a substrate, and the bioactive agent may be supported by the substrate (e.g., by a substantial portion of the area of the substrate). Methods described herein may comprise contacting the substrate of a lead body and/or an electrode of a medical electrical lead system with at least one bioactive agent, where the lead body and the electrode are connected to each other.

Percutaneous leads with laterally displaceable sections, and associated systems and methods are disclosed. A device in accordance with a particular embodiment includes a lead body that in turn includes first, second and third percutaneous portions. The first portion can carry an electrical contact, the second portion can be spaced apart from the first portion, and the third portion can be positioned between the first and second portions along a deployment axis. The third portion can have a stiffness in a direction transverse to the deployment axis that is less than a stiffness of both the first and second portions transverse to the deployment axis, and a diameter that is less than corresponding diameters of the first and second portions.

Some variations of the medical electrical lead systems may comprise a lead body comprising a proximal end and a distal end and a lumen extending at least partially therebetween, at least one electrode in the proximity of the distal end of the lead body, and a reservoir in fluid communication with the lumen, where the reservoir is located at a position removed from the distal end of the lead body. Certain variations of the medical electrical lead systems may comprise a lead body comprising a proximal end and a distal end and first and second lumens extending at least partially therebetween, and at least one electrode in the proximity of the distal end of the lead body.
