Suture retention devices and associated products and methods

摘要

A suture retention device includes a stack of suture engaging members which can be provided by coils or other segments of a spring. A suture engages with the stack so as to permit travel of the retention device along the suture in one direction more facilely than travel along the suture in the other direction. The retention device can include a housing that encloses the spring or other stack structure, and the suture can pass from a first hole in the housing, through the suture engaging members, and to a second hole in the housing. A suture anchor can be attached to the suture, and the resulting assembly can be combined with a needle designed to introduce the anchor and suture into patient tissue, e.g. in the conduct of a gastropexy procedure.

主权项

1. A surgical tether retention device, comprising:
a housing having a first end and a second end, the first end defining a first end wall surface configured for receipt against an external patient surface and a first end wall opening; a tether engaging stack structure retained by the housing, the stack structure including at least first and second adjacent stack members; a surgical tether having a housed tether portion extending through the housing in a path from the first end wall opening to a second opening spaced from the first end wall opening; the surgical tether having a first external tether portion, the first external tether portion extending out of the first end wall opening in a first direction external of the housing; the surgical tether having a second external tether portion, the second external tether portion extending out of the second opening in a second direction different from the first direction and external of the housing; wherein the housed tether portion includes at least one tether segment received between the first stack member and the second stack member; wherein the housed tether portion is further cooperatively associated with the tether engaging stack so as to urge the first and second stack members away from one another when the housing is urged along the surgical tether in the first direction and to urge the first and second stack members toward one another when the housing is urged along the surgical tether in the second direction; and wherein the stack structure comprises a coil spring, and wherein the first and second stack members are first and second coils of the coil spring.
