Abstract
Abstract A stapler device includes a manually grippable handle containing a drive and a trigger to activate the drive mechanism, a barrel fixed to the handle, a guide for holding a staple to be ejected and formed to accommodate a suture thread fixed to the staple, and an ejector driven by the drive through the barrel for ejecting a staple out through the guide into a bone to enable the suture, so anchored to the bone, to be used for various medical operations.

Claims Analysis
Total Claims: 29
Claim 1
Independent Claim
168 words
A device for implanting a self-tapping staple having attached suture thread into the bone of a patient comprising: a handle; a barrel having a proximal end and a distal end, said proximal end being secured to said handle; a staple guide for holding a staple, said staple guide being secured to said distal end of said barrel, the outer end of said staple guide being formed with a bore and a recess, said bore receiving a staple and said recess in communication with said bore physically accommodating the suture thread; a power drive means for generating staple-ejecting and driving force into a bone, said force being sufficient to completely implant the staple into the bone and under the surface of the bone of a patient without predrilling a hole in the bone; an ejector pin in communication with said power drive means and transmitting said force from said power drive means to the staple held in said staple guide; and, a trigger connected to said power drive means.
Claim 2
Independent Claim
168 words
A device for implanting a self-tapping staple having attached suture thread into the bone of a patient comprising: a handle; a barrel having a proximal end and a distal end, said proximal end being secured to said handle; a staple guide for holding a staple, said staple guide being secured to said distal end of said barrel, the outer end of said staple guide being formed with a bore and a recess, said bore receiving a staple and said recess in communication with said bore physically accommodating the suture thread; a power drive means for generating staple-ejecting and driving force into a bone, said force being sufficient to completely implant the staple into the bone and under the surface of the bone of a patient without predrilling a hole in the bone; an ejector pin in communication with said power drive means and transmitting said force from said power drive means to the staple held in said staple guide; and, a trigger connected to said power drive means.
Claim 3
Dependent Claim
43 words
A device as claimed in claim 1, wherein said ejector pin is initially spaced from the staple immediately prior to activation of said trigger and constantly contacts the staple during ejecting and implanting the staple into the bone after activation of said trigger.
Claim 4
Dependent Claim
38 words
A device as claimed in claim 1, wherein said ejector pin has a from end for contact with the staple and said ejector pin contacts the staple without said front end coming into contact with the suture thread.
Claim 5
Dependent Claim
14 words
A device as claimed in claim 1, wherein said power drive means is pneumatic.
Claim 6
Dependent Claim
12 words
A device as claimed in claim 1, wherein said barrel is flexible.
Claim 7
Dependent Claim
15 words
A device as claimed in claim 1, wherein said recess comprises an axially extending slot.
Claim 8
Dependent Claim
26 words
A device as claimed in claim 1, wherein said recess comprises a pair of opposed axially extending slots for receiving a section of the suture thread.
Claim 9
Dependent Claim

A device as claimed in claim 1, wherein said recess extends to the outside surface of said barrel.
Claim 10
Dependent Claim
16 words
A device as claimed in claim 1, wherein said staple guide is separable from said barrel.
Claim 11
Dependent Claim
33 words
A device as claimed in claim 1, wherein said device comprises two parallel barrels each having a staple guide, each of said barrels also having an ejector pin connected to said power drive.
Claim 12
Dependent Claim
25 words
A device as claimed in claim 10, wherein each of said ejector pins is activated by a separate trigger, said triggers activating said ejector pins.
Claim 13
Dependent Claim
17 words
A device as claimed in claim 11, wherein said triggers sequentially activate each of said ejector pins.
Claim 14
Dependent Claim
17 words
A device as claimed in claim 10, wherein said ejector pins are activated by a single trigger.
Claim 15
Dependent Claim
18 words
A device as claimed in claim 10, wherein said single trigger activates both of said ejector pins simultaneously.
Claim 16
Dependent Claim
20 words
A device as claimed in claim 1, wherein said device further comprises a staple having a suture thread secured thereto.
Claim 17
Dependent Claim
27 words
A device as claimed in claim 15, wherein said staple is formed from an elastic material which changes shape when no longer held by said staple guide.
Claim 18
Dependent Claim
14 words
A device as claimed in claim 1, wherein said force comprises a single pulse.
Claim 19
Independent Claim
71 words
A method of treating a female patient for urinary stress incontinence, comprising: inserting a bone anchor comprising a suture thread secured thereto through the vaginal wall of the patient to enter the pubic bone, and using said suture thread for securing soft tissue of the peri-urethral area to the posterior wall of the pubic bone to thereby adjust the anatomic position of the bladder neck and the urethra of the patient.
Claim 20
Independent Claim
71 words
A method of treating a female patient for urinary stress incontinence, comprising: inserting a bone anchor comprising a suture thread secured thereto through the vaginal wall of the patient to enter the pubic bone, and using said suture thread for securing soft tissue of the peri-urethral area to the posterior wall of the pubic bone to thereby adjust the anatomic position of the bladder neck and the urethra of the patient.

A method as claimed in claim 18, further comprising the steps of forming a hole in said public bone by said step of inserting said bone anchor.
Claim 23
Dependent Claim
53 words
A method as claimed in claim 18, wherein said bone anchor is provided with a leading tip and a trailing, driven end and a longitudinal axis extending between said tip and said driven end and wherein the step of inserting said bone anchor results in a change of shape of said longitudinal axis.
Claim 24
Dependent Claim
27 words
A method as claimed in claim 21, wherein the shape of said longitudinal axis is changed by the use of a bone anchor formed from elastic material.
Claim 25
Dependent Claim
28 words
