## Abstract

An apparatus and method of treating an aneurysm by applying to an aneurysmal blood vessel a band around its exterior surface, at the position where the attachment system of the graft attaches the graft to the vessel. A strap gun device and a method for using a strap gun device permits a surgeon to secure the material band or strap around the blood vessel with the use of only a single hand.

## Claims

### Claim 1

A device to secure a material band around a blood vessel, said device comprising:
a handle;
a shaft with a first end and a second end wherein said first end is coupled to said handle and wherein said shaft has a slot at said second end, and further wherein said shaft has a first side portion and a second side portion;
a band receiving head pivotally coupled to said first side portion of said shaft wherein said device includes a hinging mechanism to rotate said band receiving head from a first position substantially parallel to said shaft to a second position substantially perpendicular to said shaft at said second end of said shaft;
a gripping means coupled to said second end of said shaft for gripping the material band in said slot between said first and second side portions of said shaft; and
a cutting means coupled to said band receiving head to cut excess material from the material band.

### Claim 2 (depends on 1)

The device of claim 1 wherein said gripping means comprises:
a trigger with a first end and a second end wherein said first end of said trigger is pivotally coupled to said first end of said shaft;
a slider arm having a first end and a second end wherein said first end of said slider arm is slidably coupled to said shaft between said first end and said second end of said shaft;
a rocker arm with a first end and a second end wherein said first end of said rocker arm is pivotally coupled to said first end of said slider arm;
a connecting arm with a first end and a second end wherein said first end of said connecting arm is pivotally coupled to said second end of said trigger and wherein said second end of said connecting arm is coupled to said rocker arm;
a holding plate coupled to said second end of said slider arm; and
a cam pivotally coupled to said second end of said slider arm wherein said cam has a first position and a second position and wherein the material band is gripped between said cam and said holding plate when said cam is in said second position.

### Claim 3 (depends on 2)

The device of claim 2 wherein said shaft includes a wall portion coupled to said first side portion of said shaft and said slider arm has a first position and a second position wherein the material band is loaded into said device when said slider arm is in said first position and said cam is in said first position adjacent said wall portion, and gripped when said slider arm is in said second position and said cam is in said second position spaced apart from said wall portion.

### Claim 4 (depends on 3)

The device of claim 3 wherein said device further comprises a fastening means coupled to said bracket to fasten said material band receiving head around said blood vessel.

### Claim 5 (depends on 4)

The device of claim 4 wherein said fastening means comprises a fastening clip inserted into said band receiving head and means for crimping said fastening clip onto the material band.

### Claim 6 (depends on 1)

The device of claim 1 wherein said cutting means comprises a blade movably coupled to said band receiving head and a blade lever operably coupled to said trigger, wherein said blade is actuated by the blade lever to cut excess material from the material band by operation of said trigger.

### Claim 7 (depends on 1)

The device of claim 1 wherein said hinging mechanism comprises:
a button slidably coupled to said first end of said shaft;
a stem with a first end and a second end wherein said first end of said stem is slidably coupled to said button;
an arm with a first end and a second end wherein said first end of said arm is pivotally coupled to said stem; and
said band receiving head is pivotally coupled to said arm, wherein said band receiving head is moved to said second position by the actuation of said button.
