Provided is a traction device for curved balloon catheter, which is characterized by comprising: a catheter (5) with a handle (2) at one end, a locator (3) and a traction balloon (4) arranged outside the catheter (5), which one or more cavities are arranged in the catheter (5), the catheter part is provided with at least one hole, at least one cavity fills and discharges the traction balloon (4) with fluid through the hole, the traction balloon (4) bends to one side when filled with fluid, and the handle (2) can drive the catheter (5) and the traction balloon (4) to rotate, thus realizing a simple and reliable traction.

Systems and methods for reducing pathogens near an implant are discussed. In some cases, the methods include reducing contaminants in a portion of a patient that has an implant and that is disposed interior to a closed surface of skin of the patient. The method can further include placing a conduit in the closed surface of skin and flowing an antimicrobial fluid into that portion of the patient to contact the antimicrobial fluid with a surface of the implant and tissue adjacent to the implant. In some cases, the antimicrobial fluid is then removed from the portion of the patient having the implant. As part of this method, biofilm near the implant can be mechanically, ultrasonically, electrically, chemically, enzymatically, or otherwise disrupted. Other implementations are described.

Systems, devices and methods for occluding the left atrial appendage (LAA). The device excludes the LAA from blood flow. The implantable device is delivered via transcatheter delivery into the LAA and secured within the LAA. The implant comprises an expandable and compliant frame and an expandable and conformable tubular foam body. A delivery and tether retraction system includes a handle for controlling a pusher and tether. The pusher may be moved a distance away from the implant without changing the orientation of the implant, while the tether is still attached to the implant. Severing the tether and proximally retracting a control on the hand piece by a distance causes the severed end to advance distally by at least about twice that distance. A loader includes a conical portion with guides and a reservoir for submerging the foam prior to loading and delivery.

Apparatuses and methods for treating tumors. A method of treatment may include reducing the microvasculature of a region between a tumor and a lumen through or adjacent to the tumor (e.g., by administering radiation therapy targeting the tumor), isolating a segment of a lumen proximate to the tumor, and administering a dose of a chemotherapeutic agent to the segment.

Systems, devices and methods for occluding the left atrial appendage (LAA). The device excludes the LAA from blood flow. The implantable device is delivered via transcatheter delivery into the LAA and secured within the LAA. The implant comprises an expandable and compliant frame having anchors and an expandable and conformable tubular foam body. A delivery and tether retraction system includes a handle for controlling a pusher and tether. The pusher may be moved a distance away from the implant without changing the orientation of the implant, while the tether is still attached to the implant. A loader includes a conical portion with guides and a reservoir for submerging the foam implant prior to loading and delivery.

Disclosed are compositions, devices, systems, kits, and methods for neural ablation.

Left atrial occlusion devices and methods of implantation. The left atrial occlusion devices can have a plurality of flexible elongate members forming a distally open cage configuration when expanded. The distal ends of the elongate members can optionally be atraumatic.

An interferential current therapy kit for treatment of a patient following an orthopedic shoulder surgery includes, within a container for facilitating the distribution and transport of the kit, a first plurality of electrodes, a second plurality of electrodes and an interferential current therapy control unit. The interferential current therapy control unit is configured to supply interferential current electrical impulses, via the electrodes, so as to give rise to at least one first beat impulse acting on the suprascapular nerve of the patient and so as to give rise to the at least one second beat impulse acting on at least one of an axillary nerve and a supraclavicular nerve of the patient.

Medical devices useful in interventional procedures performed under magnetic resonance imaging (MRI) are described herein. A medical device comprises a body member and a marker formed of work-hardened stainless steel attached to the body member. The stainless steel of the marker has an ultimate tensile strength of between about 100 KSI and about 225 KSI. The marker can be attached to the body member in a manner that contributes work to the stainless steel or in a manner that does not contribute work to the stainless steel. Methods of making medical devices, medical imaging methods, and methods of performing interventional medical treatment are also described herein.

An apparatus, including a flexible insertion tube having a distal end for insertion into a body cavity, and first and second conduits configured to deliver first and second fluids, respectively, to the distal end. The distal end includes a first balloon coupled to the first conduit so that the first fluid inflates the first balloon and is delivered, via one or more spray ports in the first balloon, to tissue in the body cavity, a second balloon contained within the first balloon and coupled to the second conduit so that the second fluid inflates the second balloon, and multiple splines including a flexible, resilient material and extending along a longitudinal axis of the distal end, and configured to constrain the second balloon so that inflation of the second balloon creates lobes that form, along the longitudinal axis between the lobes, channels that direct the first fluid to the spray ports.
