Patent number: 10568622Abstract: 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: GrantFiled: June 8, 2015Date of Patent: February 25, 2020Assignee: Rotation Medical, Inc.Inventors: Charles L. Euteneuer, Rebecca McCarville, Duane Frion, Nathaniel Zenz-Olson, Diane M. Feehan

Publication number: 20200000462Abstract: 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: August 22, 2019Publication date: January 2, 2020Applicant: ROTATION MEDICAL, INC.Inventors: Charles L.
