Abstract
Abstract A method of securing an end portion of a graft to a blood vessel of a patient's circulatory system during a bypass grafting procedure includes the step of inhibiting blood flow to a region of the circulatory system by inflating a number of balloons within the circulatory system, wherein a segment of the blood vessel is located in the blood flow inhibited region. The method further includes the step of creating an arteriotomy in a sidewall of the segment of the blood vessel while the number of balloons are inflated within the circulatory system. Additionally, the method includes the step of anastomosing the end portion of the graft to the segment of the blood vessel during the blood flow inhibiting step.

A method of securing an end portion of a graft to a blood vessel, comprising the steps of: inflating a balloon within the blood vessel so that the balloon partitions the blood vessel into a first vessel segment of the blood vessel and a second vessel segment of the blood vessel, wherein a flow of blood within the first vessel segment is prevented from advancing to the second vessel segment while the balloon is inflated within the blood vessel; anastomosing the end portion of the graft to the second vessel segment while the balloon is inflated within the blood vessel; and creating an arteriotomy in a sidewall of the second vessel segment while (i) the balloon is inflated within the circulatory system, and (ii) prior to the anastomosing step.

Claim 40
Independent Claim
137 words
A method of securing an end portion of a graft to a blood vessel of a circulatory system, comprising the steps of: inflating a balloon within the circulatory system so that the balloon partitions the circulatory system into a first circulatory region and a second circulatory region, wherein a flow of blood within the first circulatory region is prevented from advancing to the second circulatory region while the balloon is inflated within the circulatory system; anastomosing the end portion of the graft to the blood vessel while the balloon is inflated within the circulatory system, wherein the blood vessel is located within the second circulatory region; and creating an arteriotomy in a sidewall of a segment of the blood vessel while (i) the balloon is inflated within the circulatory system, and (ii) prior to the anastomosing step.

Claim 43
Independent Claim
155 words
A method of securing an end portion of a graft to a circulatory system, comprising the steps of: inflating a balloon within the circulatory system so that the balloon partitions the circulatory system into a first circulatory region and a second circulatory region, wherein a flow of blood within the first circulatory region is prevented from advancing to the second circulatory region while the balloon is inflated within the circulatory system; creating an arteriotomy in a sidewall of a segment of a blood vessel located within the second circulatory region while the balloon is inflated within the circulatory system; and anastomosing the end portion of the graft to the segment of the blood vessel while the balloon is inflated within the circulatory system. wherein the anastomosing step and the arteriotomy creating step are each performed while the segment of the blood vessel is covered by a substantially intact portion of the epidermis of the body.
Claim 44
Independent Claim
155 words
A method of securing an end portion of a graft to a circulatory system, comprising the steps of: inflating a balloon within the circulatory system so that the balloon partitions the circulatory system into a first circulatory region and a second circulatory region, wherein a flow of blood within the first circulatory region is prevented from advancing to the second circulatory region while the balloon is inflated within the circulatory system; creating an arteriotomy in a sidewall of a segment of a blood vessel located within the second circulatory region while the balloon is inflated within the circulatory system; and anastomosing the end portion of the graft to the segment of the blood vessel while the balloon is inflated within the circulatory system. wherein the anastomosing step and the arteriotomy creating step are each performed while the segment of the blood vessel is covered by a substantially intact portion of the epidermis of the body.
Claim 45
Independent Claim
136 words
A method of securing an end portion of a graft to a blood vessel of a circulatory system, comprising the steps of: inflating a balloon within the circulatory system so that the balloon creates a partition between a first circulatory region and a second circulatory region, wherein a flow of blood within the first circulatory region is inhibited from advancing to the second circulatory region while the balloon is inflated within the circulatory system; anastomosing the end portion of the graft to the blood vessel while the balloon is inflated within the circulatory system, wherein the blood vessel is located within the second circulatory region; and creating an arteriotomy in a sidewall of a segment of the blood vessel while (i) the balloon is inflated within the circulatory system, and (ii) prior to the anastomosing step.
Claim 46
Independent Claim
