Abstract
Abstract An apparatus is provided for suturing a perforation in a side wall of a patient's blood vessel. The apparatus includes an outer sheath (36) having a longitudinal passage defined therethrough. The outer sheath (36) is adapted to be inserted through the perforation (30) in the patient's blood vessel (24). The apparatus includes at least a first suture point and at least a first suture thread attached to said first suture point. A carrier device is provided for carrying the first suture point in a distal direction through the longitudinal passage of the outer sheath (36) into the patient's blood vessel (24) and for pulling the first suture point in a proximal direction through the side wall (32) of the patient's blood vessel (24). At least two such suture points and suture threads are preferably so attached to the patient's blood vessel (24) and are then utilized to close the perforation (30).

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
101 words
An apparatus for suturing a perforation in a side wall of a patient's blood vessel, comprising: an outer sheath having a longitudinal passage defined therethrough, said outer sheath being adapted to be inserted through the perforation in the patient's blood vessel; a first suture point; a first suture thread attached to said first suture point; and carrier means for carrying said first suture point in a distal direction through said longitudinal passage of said outer sheath into the patient's blood vessel and for pulling said first suture point in a proximal direction through the side wall of the patient's blood vessel.
Claim 2
Dependent Claim
86 words
Apparatus according to claim 1, and including a second suture point; a second suture thread attached to said second suture point; and wherein said carrier means further provides a means for carrying said second suture point in said distal direction through said longitudinal passage of said outer sheath into the patient's blood vessel and for pulling said second suture point in said proximal direction through the side wall of the patient's blood vessel at a circumferentially spaced position around said perforation from said first suture point.
Claim 3
Dependent Claim
40 words
Apparatus according to claim 2, wherein perforation closing means are provided for pulling said suture points laterally toward each other when a tension force is applied to said suture threads after said suture points are placed through the side wall.
Claim 4
Dependent Claim
55 words
Apparatus according to claim 2 or 3, wherein said carrier means comprises an elongated carrier shaft having a proximal end and a distal end; and first and second laterally extendable arms connected to said distal end of said carrier shaft, said first and second suture points being carried by said first and second arms, respectively.
Claim 5
Dependent Claim
40 words
Apparatus according to claim 4, wherein said arms are extendable from a retracted position wherein said arms are received in said longitudinal passage of said outer sheath, to a laterally extended position wherein said arms extend laterally beyond said sheath.
Claim 6
Dependent Claim
37 words
Apparatus according to claim 4 or 5, wherein said indicator means are located on said shaft, for indicating an orientation of said arms within the blood vessel to a physician viewing said proximal end of said shaft.
Claim 7
Dependent Claim
37 words
Apparatus according to claim 5 or 6, wherein said intermediate insertion sheath means are provided for compressing said arms to a laterally retracted position and for inserting said arms into said longitudinal passage of said outer sheath.
Claim 8
Dependent Claim
47 words
Apparatus according to any preceding claim, wherein said carrier means comprises an elongated carrier shaft having a proximal end and a distal end; and a first laterally extendable arm connected to a proximal portion of said shaft, said first suture point being carried by said first arm.
Claim 9
Dependent Claim
32 words
Apparatus according to claim 8, wherein said first arm is hollow and has an arm passage extending therethrough; and said first suture thread extends through said arm passage of said first arm.
Claim 10
Dependent Claim
28 words
Apparatus according to claim 8 or 9, wherein said carrier shaft has a longitudinal shaft passage defined therein, and said first suture thread extends through said shaft passage.
