Aneurysm clip and method of manufacture

Claim 2

An aneurysm clip which comprises an elongated main section of spring metal and a pair of short length jaw addition sections attached to end portions of the main section on opposite sides of the main section, the main section being formed to a central spring portion, diverging first connecting portions extending from the central spring portion, converging second connecting portions extending from the first connecting portions, and jaw end portions extending from the converging second connecting portions, the second connecting portions crossing, one of the jaw addition sections including a guide bar extension section extending in overlying relation to one of the second connecting portions associated with an opposed jaw, said one of the second connecting portions being guided between an opposed second connecting portion and the guide bar extension section, the jaw end portions being arranged so that each of the jaw end portions is opposed to one of the short length jaw addition sections, the central spring section urging the jaw end portions toward engaged position with the jaw addition sections.

Claim 3

An aneurysm clip as in claim 1 in which the guide bar extension is spaced from said opposed second connecting portion by an amount substantially equal to the diameter of said one of the second connecting portions associated with an opposed jaw.

Claim 4

In the manufacture of an aneurysm clip, the method of preparing a main section elongate spring wire blank and a short section elongate spring wire blank, forming the main section blank having a single width jaw at one end and a double width jaw adjacent the other end with a central curved spring portion at the one end of the clip between connecting portions extending to respective jaws at the other end urged to face-to-face abutment by the spring portion, from the spring portion the connecting portions successively diverge, converge, cross and connect the jaws to the spring portion, forming the short section blank to have oppositely extending jaw addition and guide portions connected by an intermediate connecting portion, supporting the guide portion in parallel relation to the jaw addition portion and offset from alignment therewith, securing the jaw addition portion of the short section to the single width jaw of the main section to form a second double width jaw urged toward face-to-face engagement with the first double width jaw and with the connecting portion of the main section extending from the first double width jaw extending between the guide portion of the short section and the connecting portion of the main section extending from the second double width jaw portion thereof, and removing portions from the ends of the jaws to reduce the jaws to the desired length.

Claim 5

In the manufacture of an aneurysm clip, the method of preparing a main section elongate spring wire blank and a short section elongate spring wire blank, forming the main section blank having a single width jaw at one end and a double width jaw adjacent the other end with a central curved spring portion at the one end of the clip between connecting portions extending to respective jaws at the other end urged to face-to-face abutment by the spring portion, from the spring portion the connecting portions successively diverge, converge, cross and connect the jaws to the spring portion, forming the short section blank to have oppositely extending jaw addition and guide portions connected by an intermediate connecting portion, supporting the guide portion in parallel relation to the jaw addition portion and offset from alignment therewith, securing the jaw addition portion of the short section to the single width jaw of the main section to form a second double width jaw urged toward face-to-face engagement with the first double width jaw and with the connecting portion of the main section extending from the first double width jaw extending between the guide portion of the short section and the connecting portion of the main section extending from the second double width jaw portion thereof, and removing portions from the ends of the jaws to reduce the jaws to the desired length.
