US Patent:

20130172920, Jul 4, 2013

Filed:

Dec 20, 2012

Appl. No.:

13/722940

Inventors:

Charles L. EUTENEUER - St. Michael MN, US
Nathaniel Z. ZENZ-OLSON - Blaine MN, US
John QUACKENBUSH - North Oaks MN, US
Jeff SIMS - Apple Valley MN, US
Craig Van Kampen - Oakdale MN, US

International Classification:

A61B 19/00

US Classification:

606185

Abstract:

A tissue marker assembly which can be useful with an implant delivery system for delivering a sheet-like implant is disclosed. The tissue marker assembly can include a delivery sleeve with a tissue marker slidably disposed within a lumen therethrough. A proximal handle can be coupled to the tissue marker and delivery sleeve, having a first part and a second part. The second part of the proximal handle can be releasably attached to the tissue marker proximal end so that the second part can be removed to allow the delivery sleeve to be removed proximally over the tissue marker after it is affixed to tissue. The distal portion of the marker can include a plurality of longitudinally extending arms when unconstrained project outward from the shaft to retain the marker's position in tissue.

International Classification:

A61F 2/08

US Classification:

623 1311

Abstract:

An implant delivery system for delivering a sheet-like implant is disclosed. The implant delivery system includes a distal guidewire port for receiving the proximal end of guidewire after the guidewire distal end has been affixed to a first point on bone or other tissue. The implant delivery system is tracked over the guidewire to a selected position defined by the guidewire attachment. The device includes an implant spreader assembly disposed proximate the distal end of a delivery shaft. The implant spreader assembly includes a first arm and a second arm. The arms are coupled to the delivery shaft such that the first arm and second arm are moveable between a closed position and an open position. When pivoting to the open position the distal end of each arm travels in a generally transverse direction to spread a sheet-like implant.

International Classification:

A61B 17/88

US Classification:

606 96, 606102

Abstract:

A guidewire for use with an implant delivery system in delivering a sheet-like implant is disclosed. The guidewire can include a distal tissue fixation member for releasable connection to a first location proximate a treatment site. An implant delivery system can include a distal guidewire port for receiving the proximal end of the guidewire. The implant delivery system is tracked over the guidewire to a selected position defined by the guidewire attachment. The tissue fixation member includes means for temporarily or reversibly fixing the distal end of the guidewire to tissue, such as bone. The means for affixing can include a K-wire, a screw, a pin or other fixation member.
