Abstract
Abstract The method and apparatus of the invention use ultrasonic energy in the form of mechanical vibrations transmitted by a tool member to close off small severed blood vessels, such as in humans, by the formation of closures at the terminal portions thereof, and stop what is called ''''oozes'''', that requires constant mopping or cleaning techniques during an operation. This tool member may be in the form of a knife ultrasonically vibrated to simultaneously sever and close off respective terminal portions of the severed blood vessels while performing surgical procedures. The tool member, of a proper configuration, may also join together layers of tissue, including the walls of unsevered blood vessels, and with respect to the latter is foreseen as replacing the ''''tying off'''' of arteries and veins currently necessary in surgery.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
114 words
A method of joining together overlapping portions of layers of tissue in vivo, comprising the steps of A. applying ultrasonic mechanical vibrations to the overlapping portions of said layers of tissue in their area of overlap, said mechanical vibrations being applied in a direction substantially normal to said area of overlap, B. simultaneously compressing said layers of tissue together in their area of overlap, C. selecting the frequency and amplitude of said ultrasonic mechanical vibrations to produce a superficial heating at the interface of said overlapping layers of tissue, and D. continuing the application of said mechanical vibrations and compressive force until said layers of tissue are fused together at said superficially heated interface.
Claim 2
Independent Claim
114 words
A method of joining together overlapping portions of layers of tissue in vivo, comprising the steps of A. applying ultrasonic mechanical vibrations to the overlapping portions of said layers of tissue in their area of overlap, said mechanical vibrations being applied in a direction substantially normal to said area of overlap, B. simultaneously compressing said layers of tissue together in their area of overlap, C. selecting the frequency and amplitude of said ultrasonic mechanical vibrations to produce a superficial heating at the interface of said overlapping layers of tissue, and D. continuing the application of said mechanical vibrations and compressive force until said layers of tissue are fused together at said superficially heated interface.
Claim 3
Independent Claim
164 words
A method of joining together layers of tissue in vivo, with a tool member having a working surface, comprising the steps of A. overlapping the layers of tissue in contact with each other, B. applying the working surface of said tool member against said overlapping portions at a surface thereof, such that said working surface applies a small compressive force to said tissue traversing the area of overlap, C. vibrating the working surface of said tool member at an ultrasonic rate to apply an additional recurring force to said layers of tissue, with said force having a substantial component of vibration normal to the overlapped surfaces of said layers of tissues, D. selecting the frequency of said ultrasonic rate so as to produce an optimum flow of the collagenous elements in said layers of overlapping tissue, and E. continuing the application of said ultrasonic vibrations until a bond in formed between the collagenous elements, so as to join together said overlapping layers of tissue.
Claim 4
Independent Claim
164 words
A method of joining together layers of tissue in vivo, with a tool member having a working surface, comprising the steps of A. overlapping the layers of tissue in contact with each other, B. applying the working surface of said tool member against said overlapping portions at a surface thereof, such that said working surface applies a small compressive force to said tissue traversing the area of overlap, C. vibrating the working surface of said tool member at an ultrasonic rate to apply an additional recurring force to said layers of tissue, with said force having a substantial component of vibration normal to the overlapped surfaces of said layers of tissues, D. selecting the frequency of said ultrasonic rate so as to produce an optimum flow of the collagenous elements in said layers of overlapping tissue, and E. continuing the application of said ultrasonic vibrations until a bond in formed between the collagenous elements, so as to join together said overlapping layers of tissue.
Claim 5
Dependent Claim
25 words
A method as claimed in claim 2, wherein said step of vibrating the working surface is in the range of approximately 20 Kc/sec. to 100Kc/sec.
