Abstract
Abstract A method and devices are provided for performing end-to-side anastomoses between the severed end of a first hollow organ and the side-wall of a second hollow organ utilizing transluminal approach with endoscopic assistance, wherein the first and second hollow organs can be secured utilizing a biocompatible glue, clips or by suturing. These methods and devices find particular utility in coronary bypass surgery, including, in particular, where the first hollow organ is the left internal mammary artery (LIMA) and the second hollow organ is the left anterior descending coronary artery (LAD).

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
192 words
A method for establishing an end-to-side
anastomosis between a severed end of a first hollow organ
and a side-wall of a second hollow organ, the method
comprising: (a) introducing a catheter, having proximal and
distal ends, into the first hollow organ and passing the
catheter through the first organ until the distal end of
the catheter is substantially adjacent to the severed end
of the first hollow organ, the catheter having a
selectively operable cutter adapted to remove a portion of
the side-wall of the second hollow organ; (b) positioning the severed end of the first
hollow organ in proximity with the site for anastomosis of
the second hollow organ; (c) securing the severed end of the first
hollow organ in sealing engagement with the side-wall of
the second hollow organ, thereby defining a region of
securement on a side-wall of the second hollow organ; and (d) activating the cutter to remove a portion
of a side-wall of the second hollow organ thereby creating
an opening within the region of securement defined by the
engagement of the severed end of the first hollow organ
with the side-wall of the second hollow organ.
Claim 2
Dependent Claim
16 words
The method of claim 1, wherein the first and
second hollow organs are both vascular lumens.
Claim 3
Dependent Claim
25 words
The method of claim 1, wherein the first hollow
organ is the left internal mammary artery and the second
hollow organ is a coronary artery.
Claim 4
Dependent Claim
41 words
The method of claim 1, wherein the method
further includes: generating an area of negative pressure in the
interior of the catheter near the severed end, thereby
engaging the side-wall of the coronary artery with the
severed end of the LIMA.
Claim 5
Dependent Claim
42 words
The method of claim 1, wherein the securing of
the severed end of the first hollow organ in sealing
engagement with the side-wall of the second hollow organ,
includes stapling the first hollow organ to the sidewall
of the second hollow organ.
Claim 6
Independent Claim
231 words
A method for performing end-to-side anastomosis
between a severed end of a first hollow organ and a side-wall
of a second hollow organ, the method comprising: (a) introducing a catheter, having proximal and
distal ends, into the first hollow organ and passing the
catheter through the first organ until the distal end of
the catheter is substantially adjacent to the severed end
of the first hollow organ, the catheter having a corkscrew
element and a selectively operable cutter adapted to
remove a portion of the side-wall of the second hollow
organ; (b) positioning the severed end of the first
hollow organ in proximity with the site for anastomosis of
the second hollow organ; (c) activating the corkscrew element whereby
corkscrew element penetrates the side wall of the severed
hollow organ and the severed end of the first hollow organ
is held in mating relationship with the second hollow
organ; (d) securing the severed end of the first
hollow organ in sealing engagement with the side-wall of
the second hollow organ, thereby defining a region of
securement on a side-wall of the second hollow organ; and (e) activating the cutter to remove a portion
of a side-wall of the second hollow organ thereby creating
an opening within a region of securement defined by the
engagement of the severed end of the first hollow organ
with the side-wall of the second hollow organ.
Claim 7
Dependent Claim
16 words
The method of claim 6, wherein the first and
second hollow organs are both vascular lumens.
Claim 8
Dependent Claim
25 words
The method of claim 6, wherein the first hollow
organ is the left internal mammary artery and the second
hollow organ is a coronary artery.
Claim 9
Dependent Claim
41 words
The method of claim 6, wherein the method
further includes: generating an area of negative pressure in the
interior of the catheter near the severed end, thereby
engaging the side-wall of the coronary artery with the
severed end of the LIMA.
Claim 10
Dependent Claim
42 words
The method of claim 6, wherein the securing of
the severed end of the first hollow organ in sealing
engagement with the side-wall of the second hollow organ,
includes stapling the first hollow organ to the side-wall
of the second hollow organ.
Claim 11
Dependent Claim

A catheter for performing an end-to-side
anastomosis between a severed end of a first hollow organ
and a side-wall of a second hollow organ of a patient,
comprising: an elongated body having proximal and distal ends and
adapted for introduction into and through the first hollow

cutter.
Claim 15
Dependent Claim
44 words
The catheter of claim 11, wherein the catheter
further includes a corkscrew element adapted to engage the
side-wall of second hollow organ whereby the severed end
