Abstract
Abstract Anastomosis systems include fittings and compression mechanisms for effecting end-end or end-side couplings of biological or synthetic bypass grafts to vessel locations. The fittings are tubular and surround end regions of the graft. In some applications an end region of the graft is everted and surrounds an exterior of the fitting, in which case the preferred compression mechanism is a retaining ring. A tool is used to evert the graft end region. In other applications, the fitting has an interior groove that receives an expandable retaining ring that urges the graft end region radially outwardly against the fitting. A graft deploying and securing system includes a needle for puncturing vessel tissue, a dilator, and a sheath adapted for containing a graft/fitting combination and guiding the combination into the vessel through an opening formed by the needle and dilator.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
83 words
An anastomotic connector comprising: a fitting having a tubular portion and a flange extending substantially transverse from a distal end thereof, the flange having a thickness and a slot extending non-radially with respect to the tubular portion through the entirety of the thickness and defining an acute tissue dilating tip configured for insertion into an opening within a vessel wall, wherein rotation of the fitting facilitates entry of the flange into the opening; and at least one tab extending from the tubular portion.
Claim 2
Dependent Claim
83 words
An anastomotic connector comprising: a fitting having a tubular portion and a flange extending substantially transverse from a distal end thereof, the flange having a thickness and a slot extending non-radially with respect to the tubular portion through the entirety of the thickness and defining an acute tissue dilating tip configured for insertion into an opening within a vessel wall, wherein rotation of the fitting facilitates entry of the flange into the opening; and at least one tab extending from the tubular portion.
Claim 3
Dependent Claim
27 words
The connector of claim 1 additionally comprising a ring adapted to fit over the tubular portion and to hold tissue positioned between the ring and the flange.
Claim 4
Dependent Claim
21 words
The connector of claim 2 wherein the at least one tab is configured to secure the ring to the tubular portion.
Claim 5
Dependent Claim
30 words
The connector of claim 1 wherein at least one section of tubing is disposed along at least a portion of an edge of the flange the tubing defining a lumen.
Claim 6
Dependent Claim
16 words
The connector of claim 4 additionally comprising a wire disposed at least partially through the lumen.
Claim 7
Dependent Claim
41 words
The connector of claim 1 , wherein the flange comprises a first portion and a second portion separated form the first portion by the slot, the first portion of the flange being longitudinally offset from the second portion of the flange.
Claim 8
Dependent Claim
21 words
The connector of claim 6 , wherein the first portion of the flange longitudinally overlaps the second portion of the flange.
Claim 9
Dependent Claim
97 words
An anastomotic graft and fitting system comprising: a fitting having a tubular portion with a first radius, a proximal end and a flared distal end, the flared distal end having an edge defining at least one additional radius larger than the first radius, the edge additionally defining at least one aperture extending into the flared distal end, and wherein at least one section of tubing is disposed along at least a portion of the edge, the tubing defining a lumen; a wire at least partially disposed through the lumen; and a tubular graft affixed to the fitting.
Claim 10
Dependent Claim
97 words
An anastomotic graft and fitting system comprising: a fitting having a tubular portion with a first radius, a proximal end and a flared distal end, the flared distal end having an edge defining at least one additional radius larger than the first radius, the edge additionally defining at least one aperture extending into the flared distal end, and wherein at least one section of tubing is disposed along at least a portion of the edge, the tubing defining a lumen; a wire at least partially disposed through the lumen; and a tubular graft affixed to the fitting.
Claim 11
Independent Claim
147 words
A method for creating an anastomosis comprising: creating a puncture in a vessel wall; disposing a fitting near said puncture, said fitting having a tubular portion with a first radius and a proximal end, the fitting having a flared distal end defining an edge, the edge defining at least one additional radius larger than the first radius, the edge additionally defining at least one aperture extending into the flared distal end; rotating the fitting such that the aperture captures the vessel wall as the edge is introduced into the puncture and through the vessel wall; and continuing to rotate the fitting until the entire flared distal end passes through the puncture and the vessel wall such that when the rotation is complete the flared distal end is disposed inside a vessel lumen defined by said vessel wall and the tubular portion is disposed outside the vessel lumen.
Claim 12
Independent Claim
147 words
A method for creating an anastomosis comprising: creating a puncture in a vessel wall; disposing a fitting near said puncture, said fitting having a tubular portion with a first radius and a proximal end, the fitting having a flared distal end defining an edge, the edge defining at least one additional radius larger than the first radius, the edge additionally defining at least one aperture extending into the flared distal end; rotating the fitting such that the aperture captures the vessel wall as the edge is introduced into the puncture and through the vessel wall; and continuing to rotate the fitting until the entire flared distal end passes through the puncture and the vessel wall such that when the rotation is complete the flared distal end is disposed inside a vessel lumen defined by said vessel wall and the tubular portion is disposed outside the vessel lumen.
Claim 13
Dependent Claim
38 words
The method of claim 9 additionally comprising the step of securing the fitting to the vessel wall by advancing a ring over the tubular portion such that the ring fixes the vessel wall against the flared distal end.
Claim 14
Dependent Claim
13 words
The method of claim 9 wherein the fitting is attached to a graft.
Claim 15
Dependent Claim
58 words
The method of claim 9 wherein the distal flared end additionally comprises at least one section of tubing disposed at least partially along the edge, said tubing defining a lumen; and wherein a wire disposed in the lumen is inserted through the vessel wall and through the lumen to facilitate placing the flared end through the vessel wall.
Claim 16
Dependent Claim
36 words
The method of claim 9 wherein the puncture is created by introducing into the vessel wall a dilating tip in the flared distal end created by the edge and a second edge defined by the aperture.
Claim 17
Dependent Claim
19 words
The method of claim 9 wherein the flared distal end does not move relative to the fitting tubular portion.
