摘要： In some examples, a catheter includes an elongated body including a proximal portion and a distal portion. The elongated body includes an inner liner, an outer jacket, a structural support member positioned between at least a portion of the inner liner and at least a portion of the outer jacket, and an expandable member coupled to the structural support member at the distal portion of the elongated body. The expandable member may be configured to expand radially outward, e.g., to engage a clot within vasculature of a patient.

摘要： In some examples, an aspiration catheter system includes an outer catheter and an inner catheter configured to be positioned within the outer catheter lumen, and an alignment element. The outer catheter defines an outer catheter lumen and an outer catheter distal opening. The inner catheter defines an inner catheter lumen, an inner catheter distal opening, and a plurality of sidewall openings proximal to the inner catheter distal opening. The alignment element is configured to indicate a predetermined position of the inner catheter relative to the outer catheter when the inner catheter is received within the outer catheter distal opening. When the inner catheter is at the predetermined position, at least one sidewall opening of the plurality of sidewall openings remains positioned within the outer catheter lumen and at least one other sidewall opening of the plurality of sidewall openings is positioned distal to the outer catheter distal opening.

摘要： In some examples, a catheter may include a catheter body, a first expandable member, and a second expandable member. The catheter body may define a first lumen, a second lumen, a delivery port, and a surface extending from the delivery port into the first lumen. The first lumen may define a first central longitudinal axis. The second lumen may define a second central longitudinal axis spaced from the first central longitudinal axis in a direction orthogonal to the second central longitudinal axis. The delivery port may be in fluid communication with the first lumen. The surface extending from the delivery port into the first surface may be oriented at an obtuse or acute angle relative to the first central longitudinal axis.

摘要： In some examples, a catheter includes an elongated body comprising proximal and distal portions. The distal portion of the elongated body comprises an inner liner that includes a proximal liner section and a distal liner section that include different materials, and an outer jacket positioned over the inner liner. The distal liner section has a first hardness and the proximal liner section has a second hardness, where the first hardness is less than the second hardness.

摘要： An elongate shaft and associated systems and methods are disclosed herein. In some embodiments, the elongate shaft comprises a lumen extending along a length of the elongate shaft, and a structure radially peripheral to the lumen. The structure can be tapered in a distal direction such that an outermost cross-sectional dimension at a proximal portion of the structure is greater than an outermost cross-sectional dimension at a distal portion of the structure. An innermost cross-sectional dimension of the structure can be generally constant along all or a portion of the length of the elongate shaft. In some embodiments, the structure can comprise a plurality of layers or regions.
