Medical devices and methods for making and using medical devices are disclosed. An example medical device may include a catheter. The catheter may include a catheter shaft and a balloon. The balloon may comprise a cone portion, a waist portion, and a body portion. A fiber braid may be disposed along the balloon. An inner surface of the waist portion may be thermally bonded to an outer surface of the catheter shaft and an inner surface of the fiber braid may be adhesively bonded to an outer surface of the waist portion.

Medical balloon

Medical devices for sympathetic nerve modulation are disclosed. An example medical device for sympathetic nerve modulation may include a catheter shaft having a distal region. An expandable member may be coupled to the distal region. A flexible circuit assembly may be attached to the expandable member. The flexible circuit assembly may include a first electrode strip, a second electrode strip, and a sensor strip disposed between the first electrode strip and the second electrode strip. The first electrode strip may include a first electrode. The second electrode strip may include a second electrode. The first electrode and the second electrode may define a pair of bipolar electrodes.

Medical devices with flexible circuit assemblies

Expandable occlusive plugs and methods of using them are disclosed. The devices generally include an expandable framework at least partially covered by a membrane. The occlusive plugs can be used for occlusion of body lumens and/or to limit migration of embolic agents to non-target sites.

Systems and methods for vascular occlusion

A medical device for sympathetic nerve ablation may include a catheter shaft, an expandable member disposed on or coupled to the catheter shaft, and a plurality of elongate electrode assemblies each constructed as a flexible circuit having a plurality of layers. The expandable member may be configured to shift between an unexpanded configuration and an expanded configuration. The plurality of electrode assemblies may be disposed on an outer surface of the expandable member. Each of the plurality of electrode assemblies may include enhanced tear resistance properties such as through the inclusion of a reinforcement structure with one or more of the layers of the electrode assemblies.

Tear resistant flex circuit assembly

Medical devices and methods for making and using medical devices are disclosed. An example medical device may include a catheter shaft. An expandable balloon may be coupled to the catheter shaft. The balloon may be capable of shifting between a folded configuration and an expanded configuration. A plurality of elongate electrode assemblies may be disposed on the balloon. A cover layer may be deposited on the electrode assemblies. Portions of the electrode assemblies may be free of the cover layer.

Ablation balloon with vapor deposited cover layer

Medical devices and methods for forming the medical devices are disclosed in the present application. In one illustrative example an occlusion balloon comprises an outer balloon member, and an inner balloon member having an inner wall and an outer wall and extending through at least a portion of the outer balloon member. In at least some examples, when forces acting on the inner wall of the inner balloon member equal forces acting on the outer wall of the inner balloon member, the inner balloon member defines a lumen.

Occlusion device

Medical devices and methods for making and using the same are disclosed. An example medical device may include a medical device for tissue ablation. The medical device may include an elongated shaft having a distal region. An inflatable balloon may be mounted to the distal region. The inflatable balloon may include a body region, a proximal waist, a distal waist, a proximal cone region, and a distal cone region. A skirt may be attached to the inflatable balloon and may extend proximally from the body region. An electrode assembly may be applied directly to an outer surface of the body region of the inflatable balloon. The electrode assembly may include a first conductive member applied directly to the outer surface of the body region of the inflatable balloon and extending proximally therefrom along an outer surface of the skirt.

Medical devices for renal nerve ablation

Medical devices and methods for making and using medical devices are disclosed. An example medical device may include a medical device for modulating nerves. The medical device may include an elongate shaft having a distal region. A balloon may be coupled to the distal region. An electrode may be disposed within the balloon. A virtual electrode may be defined on the balloon. The virtual electrode may include a conductive region having an edge and a peripheral region disposed at least partially along the edge of the conductive region. The peripheral region may be configured to dissipate forces, electrical current, or both accumulating along the edge of the conductive region.

Medical devices for modulating nerves

Medical devices and methods for making and using medical devices are disclosed. An example medical device may include a medical device for modulating nerves. The medical device may include an elongate shaft having a distal region. A balloon may be coupled to the distal region. An electrode may be disposed within the balloon. A virtual electrode may be defined on the balloon. The virtual electrode may include a region having a first conductive layer and a second conductive layer.

An expandable medical balloon for transmitting radiofrequency energy, the medical balloon comprising at least one polymeric electrically-insulating layer and at least one polymeric electrically-conductive layer, wherein at least portions of the polymeric electrically-insulating layer are moveable relative to the polymeric electrically-conductive in said at least one pressurizable expanded state.

Renal nerve modulation balloon and methods of making and using the same

A carrier tube assembly for packaging a medical catheter is disclosed. The carrier tube assembly includes an elongate tube, a medical catheter, and a plug. At least a distal portion of the elongate shaft of the medical catheter is positioned in the lumen of the elongate tube such that the proximal end of the elongate tube is hermetically sealed around a portion of the hub assembly of the medical catheter. The plug is inserted into the lumen of the elongate tube at the distal end of the elongate tube, hermetically sealing the distal end of the elongate tube. Thus, a hermetically sealed environment is established within the elongate tube. The plug includes a moisture and/or oxygen absorbing agent to absorb moisture and/or oxygen in the hermetically sealed environment.
