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.

Catheter

Catheter devices, assemblies and related methods for percutaneous crossing of an occlusion in a blood vessel are disclosed. A catheter device can include a central catheter, two side tubes, and a distally-protruding, curved subintimal guidewire. The central catheter can define a central lumen that extends from a proximal end to a distal end of the central catheter. The lumen can be configured to receive a primary guidewire. The central catheter can also define at least one reentry aperture oriented transverse to the central lumen. The first and second side tubes can be coupled with the central catheter, extending along a longitudinal axis thereof, with the first side tube flanking an opposite side of the central catheter relative to the second side tube. The subintimal guidewire can extend from the first side tube, distally beyond the distal end of the central catheter, to the second side tube.

Subintimal catheter device, assembly and related methods

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, or 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.

Capture assembly and method

Catheters and related methods for supporting a guidewire or delivering an agent through a vessel stenosis or other tortuous anatomy are disclosed. A catheter can comprise an elongate shaft body and a polymer tip member disposed at a distal end of the shaft body. The shaft body and the tip member can include a liner, one or both of a braid member or a coil member surrounding the liner, and a polymer cover surrounding the braid member or the coil member. The tip member can further include one or more filaments extending from a position overlapping, underlapping, or abutting a distal end of the braid member or the coil member on their proximal ends to a position distal to the braid member or the coil member on their distal ends. The one or more filaments can include a plurality of filaments arranged in a series of contacting helical windings about the liner, the braid member, or the coil member.

Catheter tip

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.
