摘要： Percutaneous devices and methods for releasably engaging a guidewire against an inner surface of a tubular member are disclosed. A percutaneous device can include a tube member, a push member, and a fixation mechanism such as a fixation balloon. The tube member can define a lumen sized and shaped to receive one or more interventional medical devices therethrough and can have an outer diameter smaller than a lumen of a guide catheter. The push member can be attached at least to a proximal end portion of the tube member for slidably positioning a distal end portion of the tube member within and beyond a distal end of the guide catheter. The push member can include a lumen in fluid communication with an interior of the fixation balloon for delivering inflation fluid to, or removing fluid from, the balloon. The fixation balloon can be positioned on a portion of the push member and can be configured to engage a guidewire against the inner surface of the guide catheter or the tube member when inflated.

摘要： This patent document discloses perfusion catheters and related methods for treating complications related to CTO interventions or dilating a vessel occlusion while maintaining a passage through the treated vessel segment. A perfusion catheter can include a balloon formed of an inflatable tube and an elongate shaft having a lumen for providing inflation fluid to, or withdrawing inflation fluid from, the balloon. The inflatable tube can be coiled in a helical manner around a central axis into a series of windings. Adjacent windings can be stacked against and bonded to each other, and an inner surface of the series of windings, when inflated, can define the passage. The elongate shaft can be eccentrically attached to a proximal portion of the balloon and the shaft's lumen can be in fluid communication with the interior of the balloon, specifically the inflatable tube. The inflatable tube can include two different polymer tubes, one slightly smaller than the other.

摘要： Vascular introducer systems, kits, and methods providing or creating access to vessels, such as radial or femoral arteries, are disclosed. A vascular introducer system includes a removable inner tubular member, a removable outer tubular, tear-away member, and an expandable passage member positioned between the inner and outer tubular members. The removable inner tubular member and the removable outer tubular, tear-away member help protect and maintain a contracted configuration of the expandable passage member when the introducer system is advanced into a vessel. The expandable passage member includes an inner surface configured to receive an elongate treatment device, for example, following removal of the inner and outer tubular members. In some examples, the expandable passage member includes one or more kink-resistant members extending along a portion of the passage member. In various examples, the expandable passage member includes a wall thickness sufficient to protect vessel surfaces, while preserving vessel access size.

摘要： Safe and convenient methods and devices for inexpensively and rapidly treating pseudoaneurysms and other subcutaneous pools of blood utilize an apparatus with an applicator that can be grasped by a user at its proximal end and which has a distal portion that can be percutaneously inserted into a pseudoaneurysm. The distal portion has at least one retaining structure on at least one surface; the retaining structure(s) serve to collectively retain a clotting agent as the distal portion is inserted into the pseudoaneurysm. The clotting agent in the retaining structure(s) is exposed to blood in the pseudoaneurysm and initiates a clotting cascade. Since the clotting agent is in the retaining structure(s) and is not forcibly injected into the blood, the clotting cascade causes blood to clot at or near the surface of the applicator. The clot is associated with the applicator until the distal portion of the applicator is removed from the pseudoaneurysm. Removing the applicator causes the patient's tissue to wipe the clot off of the applicator so that the clot remains in the pseudoaneurysm.

摘要： This patent document discloses methods for facilitating revascularization of an occlusion in a blood vessel. A method can include engaging a first guide within a vessel wall adjacent to a distal cap of the occlusion and advancing the first guide, in a retrograde direction, to a subintimal position near a proximal cap of the occlusion. A second guide can be engaged within the proximal cap or the vessel wall adjacent to the proximal cap and advanced, in an antegrade direction, until its distal end is near or axially overlaps a distal end of the first guide. A first vessel lumen, formed by advancement of the first guide, and a second vessel lumen, formed by advancement of the second guide, can be connected by inflating a balloon positioned at or near the distal end of the second guide. The distal end of the first guide can be received by a passage of the inflated balloon, the balloon can be subsequently deflated to collapse the passage and clamp a passage wall against the first guide's distal end, and the balloon and first guide can be pulled into an antegrade guide catheter.

摘要： Catheters and methods for supporting a guidewire or delivering a radiopaque, diagnostic or therapeutic agent through a vessel stenosis or other tortuous anatomy are disclosed. A catheter can comprise an elongate shaft body and a tip member disposed at a distal end of the shaft body. The shaft body can extend from a proximal end to the distal end and can define an inner lumen. The shaft body can include a liner, a braid member surrounding the liner, a multi-layer coil surrounding the braid member, and a polymer cover surrounding the multi-layer coil. The multi-layer coil can include first and second coil layers wound in opposing directions. An outer surface portion of the polymer cover can include one or more helical threads. In an example, the one or more helical threads are positioned around a distal end portion of the shaft body. The tip member can be made from a metal or a polymer and can also include one or more helical threads around its outer surface.

摘要： Fluid delivery or removal systems and methods for use during a medical procedure are disclosed. A system can include a base member, a receptacle configured to be received by a chamber of the base member, and a pressure sensor. The base member can include a piston having the pressure sensor positioned at or near its tip, a powered actuator for imparting motive forces to the piston, and a rechargeable power supply to energize the actuator. The receptacle is configured to contain a volume of fluid partially retained by a seal member. A surface of the seal member opposite the fluid can include a cavity to receive and engage the piston's tip when the receptacle is placed in the chamber. Based on a user-defined parameter input (e.g., a desired pressure set point) received by the system, the piston can be driven in an axial direction by the powered actuator, thereby urging an amount of fluid through a distal opening in the receptacle.
