Abstract
Abstract A method for suturing puncture wounds in the human body, such as those made by surgical trocars, comprising the steps of providing insertion means and retrieval means for suturing material, inserting the insertion means and suture through the internal tissue layers adjacent to the puncture, inserting the retrieval means through the internal tissue layers, retrieving the suture, withdrawing the insertion means, retrieval means and suture, and then tightening and tieing the suture to close the puncture wound internally.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
214 words
A method for suturing puncture wounds of the human body which extend through the skin layer, subcutaneous layer, internal tissue layers, and into an internal body cavity, comprising the steps of: (A) providing suture material having at least one free end, insertion means for inserting said suture material through said internal tissue layers and into said internal cavity, and retrieval means for withdrawing said suture material from said internal cavity and through said internal tissue layers; (B) temporarily connecting said suture material to said insertion means; (C) inserting said insertion means and said suture material through said internal tissue layers adjacent to said puncture wound, whereby said free end of said suture material is inserted into said internal cavity; (D) inserting said retrieval means through said internal tissue layers adjacent to said puncture wound and into said internal cavity; (E) temporarily connecting said free end of said suture material within said internal cavity to said retrieval means; (F) withdrawing said insertion means from said internal cavity; (G) withdrawing said retrieval means and said free end of said suture material from said internal cavity through said internal tissue layers; (H) tightening said suture material whereby said puncture wound is closed by said suture material within said internal cavity and external to said internal tissue layers.
Claim 2
Independent Claim
214 words
A method for suturing puncture wounds of the human body which extend through the skin layer, subcutaneous layer, internal tissue layers, and into an internal body cavity, comprising the steps of: (A) providing suture material having at least one free end, insertion means for inserting said suture material through said internal tissue layers and into said internal cavity, and retrieval means for withdrawing said suture material from said internal cavity and through said internal tissue layers; (B) temporarily connecting said suture material to said insertion means; (C) inserting said insertion means and said suture material through said internal tissue layers adjacent to said puncture wound, whereby said free end of said suture material is inserted into said internal cavity; (D) inserting said retrieval means through said internal tissue layers adjacent to said puncture wound and into said internal cavity; (E) temporarily connecting said free end of said suture material within said internal cavity to said retrieval means; (F) withdrawing said insertion means from said internal cavity; (G) withdrawing said retrieval means and said free end of said suture material from said internal cavity through said internal tissue layers; (H) tightening said suture material whereby said puncture wound is closed by said suture material within said internal cavity and external to said internal tissue layers.
Claim 3
Dependent Claim
137 words
The method of claim 1, further comprising the steps of reconnecting said free end of said suture material to said insertion means prior to said tightening and closure of said puncture wound; again inserting said insertion means and free end of said suture material through said internal tissue layers adjacent said puncture wound, whereby said free end of said suture material is inserted into said internal cavity; again inserting said retrieval means through said internal tissue layers adjacent to said puncture wound and into said internal cavity; again temporarily connecting said free end of said suture material within said internal cavity to said retrieval means; again withdrawing said insertion means from said internal cavity; and again withdrawing said retrieval means and said free end of said suture material from said internal cavity through said internal tissue layers.
Claim 4
Dependent Claim
19 words
The method of claim 1, where said insertion means comprise a needle and said retrieval means comprise a needle.
Claim 5
Dependent Claim
32 words
The method of claim 3, where said insertion needle comprises an eyelet and said step of connecting said suture material to said insertion means comprises threading said suture material through said eyelet.
Claim 6
Dependent Claim
34 words
The method of claim 3, where said retrieval needle comprises a barbed portion and said step of connecting said suture material to said retrieval means comprises connecting said suture material to said barbed portion.
Claim 7
Dependent Claim
37 words
The method of claim 1, where said steps of inserting said insertion means and said retrieval means further comprises inserting said insertion means and retrieval means through said puncture wound itself in said skin and subcutaneous layers.
Claim 8
Dependent Claim
22 words
The method of claim 1, further comprising the step of closing said puncture wound in said subcutaneous and skin layers by suturing.
