Abstract

An elastic surgical ring clip which is of a configuration to provide a ring clip having greatly increased compressive and elastic strength. The clip may be of spherical configuration and has a central lumen which may have a variety of cross-sectional configurations to increase tissue gripping. A ring loader for loading elastic rings onto the distal end of a ring applicator device including a conical ring expander and a conical ring dilator which is slipped over and pushed along the ring expander to dilate rings and place the dilated rings on a ring applicator device distal end. A kit including a ring loader and one or more elastic surgical ring clips.

Independent Claims | See all claims (17)

  1. 1. An elastic surgical ring clip comprising:a body made of elastic material, said body having a generally spherical configuration exhibiting a pair of generally flattened and diametrically opposed faces, andmeans defining an anatomical tissue engaging lumen generally extending centrally through said elastic body with opposite ends of the lumen forming orifices centrally disposed in said opposed faces,said opposed faces having greatest cross-sectional dimensions in a plane perpendicular to a longitudinal axis of said lumen, substantially less than corresponding greatest cross-sectional dimensions of said spherical configuration of said body taken parallel to said plane,said body being made of an elastic material having sufficient elastic memory to return to its initial configuration after being stretched to enlarge said lumen so that tissue may be drawn into said lumen, whereby, upon return of said clip to its initial configuration with tissue located within said lumen, secure engagement of said clip about tissue is assured.
  2. 9. A kit for preparing a ring applicator device to apply one or more elastic surgical rings onto anatomical tissue, comprising:a plurality of elastic surgical rings each having a substantially solid body made of elastic material, said body having a generally spherical configuration exhibiting a pair of generally flattened and diametrically opposed faces, and an anatomical tissue engaging lumen generally extending centrally through said elastic body with opposite ends of the lumen forming orifices centrally disposed in said opposed faces, said opposed faces having greatest cross-sectional dimensions in a plane perpendicular to a longitudinal axis of said lumen, substantially less than corresponding greatest cross-sectional dimensions of said spherical configuration of said body taken parallel to said plane, each of said bodies being made of an elastic material having suffificient elastic memory to return to an initial configuration after beomg stretched to enlarge said lumen so that anatomical tissue may be drawn into said lumen, whereby, upon return of said clip to its initial configuration with anatomical tissue located within said lumen, secure engagement of said clip about anatomical tissue is assured,a ring loader having an elongate needle shaped receiver onto which one or more of said elastic surgical rings are loaded with the receiver inserted through the lumen,a conically shaped elastic ring expander having an apex and a base, said receiver extending from said apex and said base being configured to be temporarily mounted on the distal end of a ring applicator device, anda ring dilator having a generally conically configured ring engaging portion being slit to define a plurality of ring engaging fingers for engaging an end of one of said one or more elastic rings loaded onto said receiver whereby one or more elastic rings may be advanced from the receiver, expanded by being pushed over said conical ring expander, and positioned on the distal e or a ring applicator be being pushed beyond said conical receiver base.
  3. 13. An elastic surgical ring clip for engaging anatomical tissue, comprising:a body made of elastic material; andmeans defining an anatomical tissue engaging lumen extending generally centrally through said elastic body, said body being made of an elastic mate having sufficient elastic memory to return to its initial configuration after being stretched to enlarge said lumen so that tissue may be drawn into said lumen, said lumen having generally an elliptical configuration in a cross-se taken in a plane perpendicular to a longitudinal axis of said lumen with major and minor axes of said elliptical configuration being perpendicular to said longitudinal axis with said major axis being greater in dimension than said minor axis.
