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.

摘要： A system and method for protecting biological or other material from contamination through the steps of filling, freeze-drying, packaging, storing and use are disclosed. A system can include a flexible container, a membrane configured to transmit air or solvent vapor out of the flexible container, and a membrane frame supporting the membrane and engaged with at least one column member. The at least one column member can be configured to maintain the membrane and the membrane frame a spaced distance from one or more contents received within the flexible container. Upon application of a downward force, the at least one column member can assume a collapsed configuration. A method can include inserting a biological material, for example, into a flexible container, freeze-drying the biological material, moving the freeze-dried biological material to a portion of the flexible container that includes at least one port, and sealing the biological material within the portion.

摘要： This patent document discloses assemblies and methods for removing obstructive material from a body vessel or other cavity. An assembly can include an elongate inner member, an elongate outer member, an aspirator, one or more valves, and a waste collection reservoir. Each of the elongate members can extend from a proximal end portion to a distal end portion and can include a lumen therethrough. The elongate inner member can be partially disposed in the lumen of the elongate outer member and can be moveable along its longitudinal axis relative to the elongate outer member. The aspirator can be in flow communication with the proximal end portion of the elongate inner member for drawing the obstructive material into or through its lumen. The one or more valves can be configured and positioned to allow obstructive material removed from the body vessel or cavity to be urged toward the waste collection reservoir.

摘要： A wire control catheter for aligning and guiding a guide wire through a lesion in a vessel is provided. The wire control catheter includes a shaft having a guide wire lumen and a control wire lumen. A control wire passes through the control wire lumen and is used in combination with an articulation structure to deflect or curve a distal tip portion of the catheter. The distal catheter shaft may include a centering device for centering the catheter within the vessel. The distal catheter shaft may also include a pre-dilation balloon for dilating the lesion prior to performing angioplasty or other treatment on the lesion. A method of treatment of a blood vessel includes inserting a guide wire into the blood vessel and advancing a control wire over the guide wire until the distal tip of the catheter is near the occlusion in the blood vessel. The tip of the catheter then is deflected via a control wire and an articulation structure. The guide wire is then advanced across the occlusion. The control wire also may be advanced across the occlusion simultaneously with the guide wire or subsequent to the guide wire crossing. Prior to crossing the occlusion, the wire control catheter may be centered using a centering device. Subsequent to crossing the occlusion, the occlusion may be pre-dilated with a pre-dilation balloon of the wire control catheter.

摘要： Catheter assemblies, kits and methods allowing for the drainage or administration of fluid or small particles are disclosed. A catheter assembly can include a shaft with a lumen, an expandable retention member, an elongate actuation member and a locking mechanism. The expandable retention member can be positioned at a shaft distal end portion and can include one or more filaments forming a plurality of drainage or administration interstices of variable or uniform size. The elongate actuation member can include an actuation member distal end, directly or indirectly engaged with the expandable retention member, and an actuation member proximal end. Movement of the actuation member proximal end relative to a proximal end of the shaft can cause the expandable retention member to change from a lower-profile configuration to a higher-profile configuration. A moved position of the elongate actuation member can be secured by rotating, sliding or otherwise manipulating the locking mechanism.

摘要： Vascular dilator systems, kits, and methods allowing for sheathless introduction of a treatment device into a body vessel or body cavity are disclosed. A vascular dilator system can include a dilator assembly, including a tubular shaft and a deformable member, and optionally, the treatment device. The deformable member can include a non-biodegradable material and can have a diameter at a proximal end portion that is greater than a diameter at a distal end portion. The distal end portion of the deformable member can be coupled to an outer surface of the tubular shaft, at or near a shaft distal end portion. The proximal end portion of the deformable member can include a diameter configured to receive or stretch around a distal end portion of the treatment device. In use, the deformable member can provide a tapered bridge between the outer surface of the tubular shaft and an outer surface of the treatment device.
