Patent number: 12256984Abstract: Catheter apparatuses, systems, and methods for achieving renal neuromodulation by intravascular access are disclosed herein. One aspect of the present technology, for example, is directed to a treatment device having a multi-electrode array configured to be delivered to a renal blood vessel. The array is selectively transformable between a delivery or low-profile state (e.g., a generally straight shape) and a deployed state (e.g., a radially expanded, generally helical shape). The multi-electrode array is sized and shaped so that the electrodes or energy delivery elements contact an interior wall of the renal blood vessel when the array is in the deployed (e.g., helical) state. The electrodes or energy delivery elements are configured for direct and/or indirect application of thermal and/or electrical energy to heat or otherwise electrically modulate neural fibers that contribute to renal function or of vascular structures that feed or perfuse the neural fibers.Type: GrantFiled: September 10, 2021Date of Patent: March 25, 2025Assignee: Medtronic Ireland Manufacturing Unlimited CompanyInventors: Vincent Ku, Robert Beetel, Andrew Wu, Denise Zarins, Maria Aboytes

Publication number: 20230165596Abstract: A catheter is provided which includes an outer catheter and an extendable inner catheter. A sealing feature is positioned between the inner catheter and the outer catheter to seal the annular gap between the two while allowing axial translation. The seal may be a compliant protrusion surrounding the inner catheter and may have a chevron-shape for facilitating axial translation. The seal may be a one-way valve configured to allow antegrade flushing but prevent retrograde flow. The seal may be squeegee-like flange on the distal tip of the outer catheter. The seal may be an expandable bulge, which may be mechanically expandable or inflatable or which may be a photosensitive or electrosensitive hydrogel. The seal may include a spring that is radially compressed upon translation or rotation of the inner catheter to transiently break the seal. Also provided is a seal for sealing between the catheter and the vasculature.Type: ApplicationFiled: December 2, 2022Publication date: June 1, 2023Inventors: Maria Aboytes, Yi Yang, Brandon Yee, Chad C.

Patent number: 11376012Abstract: Devices, systems, and methods for treating vascular defects are disclosed herein. One aspect of the present technology, for example, is directed toward an occlusion device that includes a proximal portion, a distal portion, and an intermediate portion extending between the proximal portion and the distal portion. The distal portion can include a directing region and a lead-in member that extends distally from the directing region. When the occlusion device is in a deployed configuration, the intermediate portion can form a preset bend in the occlusion device that positions the directing region at an angle with respect to the proximal portion. As a result, as the occlusion device is pushed distally out of a delivery catheter into the aneurysm, the directing region directs the distal portion away from exiting the aneurysm through the neck such that the proximal portion crosses the neck and generally remains within the aneurysm.Type: GrantFiled: July 30, 2019Date of Patent: July 5, 2022Assignee: COVIDIEN LPInventors: Maria Aboytes, Arturo Rosqueta, Erik Engelson, Scott Wilson

Patent number: 10300256Abstract: In some embodiments, a medical device for recanalizing a vessel having a blockage and restoring blood flow through an obstructed blood vessel includes an expandable member coupled to a core wire and a hypotube that are movable relative to each other to manipulate the expandable member between various configurations. The expandable member having a capture structure in an expanded configuration. The expandable member can include multiple interstices formed by woven mesh filaments or braided strands through which the material blocking the vessel can pass. The capture structure can include a shape on its external surface that facilitates dislodgement and capture of the material within capture spaces created by the expandable member. Some embodiments include a capture sack or cap for capturing material and preventing material from migrating down stream of the blockage. Superoxygenated blood can be infused distal to the blockage to minimize loss of function during an ischemic event.Type: GrantFiled: April 21, 2015Date of Patent: May 28, 2019Assignee: COVIDIEN LPInventor: Maria Aboytes
