Publication number: 20240057995Abstract: A device for closing an opening in a body lumen, the device having a first elongate member with a first lumen, a second elongate member distal the first elongate member, and a needle assembly slidably cooperating with the first elongate member to position a plurality of sutures within the lumen of the first elongate member. The needle assembly includes a needle base and a plurality of needle portions extending from the needle base. Slidable movement of the needle assembly in relation to the first elongate member locates the plurality of sutures selectively mounted to the needle assembly within the first lumen.Type: ApplicationFiled: October 31, 2023Publication date: February 22, 2024Inventors: Wouter E. Roorda, Douglas H. Mehl, Rizza A. Garcia, Timothy C. Reynolds, Dinorah V. Merrill, Dawn Ma, David J. Milazzo, Aaron M. Fortson
