Patent number: 11918760Abstract: A catheter may include an inner liner, at least one support structure over the inner liner, and an outer jacket over the at least one support structure. In some examples, the catheter includes a tip jacket positioned over a distal portion of the outer jacket and extend beyond a distal-most part of the inner liner and a distal-most part of the outer jacket to define a single-layer catheter tip. In some examples, the at least one support structure may include a braid and a coil. The catheter may include a marker band over a distal portion of one of the braid or the coil. The other of the braid or the coil ends proximally of a proximal end of the marker band, such that the catheter includes a location with lower radial and/or flexural stiffness proximal of the marker band.Type: GrantFiled: March 19, 2021Date of Patent: March 5, 2024Assignee: Covidien LPInventors: Ujwal Jalgaonkar, Syamala Rani Pulugurtha, Edwin Bon, Eric Mintz

Patent number: 11452841Abstract: 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.Type: GrantFiled: April 11, 2019Date of Patent: September 27, 2022Assignee: COVIDIEN LPInventors: Ujwal Jalgaonkar, Edwin Bon, Peter Skujins, Eric Mintz

Publication number: 20210298731Abstract: 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.Type: ApplicationFiled: February 24, 2021Publication date: September 30, 2021Inventors: Syamala Rani Pulugurtha, Ujwal Jalgaonkar, Edwin Bon, Komonn Lim, Maria Sanson, Anthony Huynh
