Abstract
Abstract A surgical microclip particularly adapted for microvascular anastomoses is described as including a pair of arcuate legs interconnected by a bridging section. The clip is formed of a unitary piece of biologically acceptable, plastically deformable material, and further has two spaced "ears" to facilitate handling and removal of the clip. Also disclosed is a tool for applying the clip, comprising a tweezer-like device having a pair of arms for crimping the microclip, with a fine suction conduit extending along a bisector of the angle between the arms to hold the clip prior to crimping.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
119 words
A surgical microclip comprising a bridge portion, and a pair of spaced legs extending generally parallel from opposite ends of said bridge, a pair of ears extending generally parallel from opposite ends of said bridge in a direction opposite that of said legs, whereby said ears facilitate manipulation of said clip prior to placement and further provide means for opening said clip if removal is desired, said clip being constructed of a biologically acceptable, plastically deformable material whereby the clip may be permanently deformed by crimping to close said legs around approximated body tissues to hole the same together, and said legs terminating at distal tips, said tips being sufficiently rounded to avoid puncturing or otherwise injuring said tissues.
Claim 2
Dependent Claim
119 words
A surgical microclip comprising a bridge portion, and a pair of spaced legs extending generally parallel from opposite ends of said bridge, a pair of ears extending generally parallel from opposite ends of said bridge in a direction opposite that of said legs, whereby said ears facilitate manipulation of said clip prior to placement and further provide means for opening said clip if removal is desired, said clip being constructed of a biologically acceptable, plastically deformable material whereby the clip may be permanently deformed by crimping to close said legs around approximated body tissues to hole the same together, and said legs terminating at distal tips, said tips being sufficiently rounded to avoid puncturing or otherwise injuring said tissues.
Claim 3
Dependent Claim
21 words
A clip as described in claim 1, wherein said legs are arcuate, the concave sides of the legs facing one another.
Claim 4
Dependent Claim
42 words
A surgical technique for the apposition of tissues comprising approximating the edges of said tissues, partially everting said edges, positioning a plastically deformable clip over said edges, and crimping said clip so as to clamp said edges together without penetrating the tissues.
Claim 5
Dependent Claim
42 words
A surgical technique for the apposition of tissues comprising approximating the edges of said tissues, partially everting said edges, positioning a plastically deformable clip over said edges, and crimping said clip so as to clamp said edges together without penetrating the tissues.
Claim 6
Dependent Claim
78 words
A microvascular anastomosis technique comprising steps of aligning two vessels, approximating said vessels and simultaneously partially everting the ends of said vessels, positioning a deformable clip having spaced legs over said edges with the legs astride both everted edges, crimping said clip sufficiently to clamp said edges together between said legs but without penetrating the walls of said vessels, and repeating the everting, positioning and crimping steps around the approximated edges of the vessels to complete the anastomosis.
Claim 7
Dependent Claim
78 words
A microvascular anastomosis technique comprising steps of aligning two vessels, approximating said vessels and simultaneously partially everting the ends of said vessels, positioning a deformable clip having spaced legs over said edges with the legs astride both everted edges, crimping said clip sufficiently to clamp said edges together between said legs but without penetrating the walls of said vessels, and repeating the everting, positioning and crimping steps around the approximated edges of the vessels to complete the anastomosis.
