Publication number: 20240358423Abstract: Implant delivery systems for delivering sheet-like implants include a delivery shaft, an implant expander, a sheath, and a sheet-like implant. In some embodiments, the delivery shaft has a proximal end and a distal end. The implant expander is mounted to the distal end of the delivery shaft. The implant expander includes a central portion and a plurality of leg portions radiating from the central portion. The implant expander is evertable between an unstressed configuration in which a distal surface of the implant expander defines a concave surface, and a first compact configuration in which the distal surface of the implant expander defines a convex surface. The implant expander has a first lateral extent when the implant expander is free to assume the unstressed configuration. The sheath defines a lumen having a lumen diameter. At least a portion of the delivery shaft is slidably disposed in the lumen.Type: ApplicationFiled: July 8, 2024Publication date: October 31, 2024Applicant: Rotation Medical, Inc.Inventors: Charles L. Euteneuer, Rebecca McCarville, Duane Frion, Nathaniel Zenz-Olson, Diane M. Feehan, John Quackenbush

Publication number: 20240000450Abstract: A device for attaching a sheet-like implant to a target tissue includes a pilot member and a staple push rod. In some embodiments, the pilot member has a distal end and at least a pair of prongs extending from the distal end. The prongs are configured to form pilot holes when the distal end of the pilot member is pressed against the target tissue. The staple push rod is disposed within at least a portion of the pilot member and slidable relative thereto. The staple push rod includes at least a pair of stakes. Each stake is dimensioned to engage a surface of a staple to apply pushing forces thereto. Each stake is positioned relative to a prong along an inner surface of the pilot member so that the stakes advance into the pilot holes when the stakes are moved in a distal direction. Methods for attaching a sheet-like implant to a target tissue are also disclosed.Type: ApplicationFiled: September 14, 2023Publication date: January 4, 2024Applicant: Rotation Medical, Inc.Inventors: Charles L.

Publication number: 20210338235Abstract: A staple for attaching a sheet-like implant to tissue or bone may include first and second arms, and first and second flukes. In some embodiments, the first arm has a proximal end and a distal end, and the second arm has a proximal end and a distal end. A bridge extends from the proximal end of the first arm to the proximal end of the second arm. The first fluke has a proximal end abutting the distal end of the first arm, and the first fluke extends distally from the first arm. The first fluke has a lateral extent larger than a lateral extent of the first arm and is mounted eccentrically thereto. The first fluke includes a proximal surface projecting at an outward angle in a proximal direction away from the distal end of the first arm to engage the tissue or bone when inserted therein. The second fluke has similar features. This arrangement causes the first and second flukes to rotate in response to a pullout force on the bridge.Type: ApplicationFiled: June 15, 2021Publication date: November 4, 2021Applicant: ROTATION MEDICAL, INC.Inventors: Charles L.
