Abstract
Abstract The present invention provides an implant device and an associated method for interconnecting human vessels rapidly, safely and in a minimally invasive manner. The device comprises a first segment, a second segment, and a flow opening along the periphery of the two connected segments. The first and second segments are bendable for easy insertion into an incision made within each vessel. Upon release, each bendable segment subsequently conforms to the interior walls of a vessel to provide a sealing contact along the contact surface of the segment inserted within. The flow opening provides fluid interconnectivity between the vessels connected by the implant device. The device is configured so as to: (1) not impede flow inside a vessel; (2) prevent flow out of the openings in the vessels except for flow from one vessel to another via the connector opening; and (3) force the vessels toward each other at areas around the openings allowing the vessels to grow together so that flow in one vessel may flow to the other. The implant device may be inserted using special catheter designed specifically for the placement and release of the implant device within the vessels for interconnection thereof. The implant device is preferably provided in an assortment of sizes, shapes, configurations, etc. in order to interconnect vessels of various sizes, shapes and orientations. A system which includes a catheter having the implantable device loaded therein is also disclosed

Claims Analysis
Total Claims: 26
Claim 1
Independent Claim
100 words
A device for interconnecting vessels wherein the device is insertable within a vessel through an opening made in a vessel, comprising: a flexible segment comprising a flow opening therein for providing fluid interconnectivity between the vessel and another vessel and having an original configuration and a constricted configuration, wherein the segment is insertable into the vessel opening when in the constricted configuration and conforms to and seals with an interior wall of the vessel and provides pressure against the interior wall when in the original configuration such that material within the vessel is prevented from leaking from the vessel opening.
Claim 2
Independent Claim
100 words
A device for interconnecting vessels wherein the device is insertable within a vessel through an opening made in a vessel, comprising: a flexible segment comprising a flow opening therein for providing fluid interconnectivity between the vessel and another vessel and having an original configuration and a constricted configuration, wherein the segment is insertable into the vessel opening when in the constricted configuration and conforms to and seals with an interior wall of the vessel and provides pressure against the interior wall when in the original configuration such that material within the vessel is prevented from leaking from the vessel opening.
Claim 3
Dependent Claim
16 words
The device of claim 1 wherein the flow opening is centrally located within the flexible segment.
Claim 4
Dependent Claim
22 words
The device of claim 2 further comprising a tubular segment interconnected with the flexible segment along the periphery of the flow opening.
Claim 5
Dependent Claim
19 words
The device of claim 3 wherein the tubular segment is positioned relative to the flexible segment at an angle.
Claim 6
Dependent Claim
14 words
The device of claim 1 further comprising a channel extending from the flow opening.
Claim 7
Dependent Claim
24 words
The device of claim 5 wherein the channel has a diameter substantially equal to the diameter of the vessel or of the second vessel.
Claim 8
Dependent Claim
19 words
The device of claim 1 wherein the flexible segment is sized to accommodate a wide range of vessel sizes.
Claim 9
Dependent Claim
16 words
The device of claim 1 wherein the flexible segment is planar when in the original configuration.
Claim 10
Dependent Claim
19 words
The device of claim 1 wherein the flexible segment is at least partially cylindrical when in the original configuration.
Claim 11
Dependent Claim
16 words
The device of claim 9 wherein the flexible segment is cylindrical when in the original configuration.
Claim 12
Dependent Claim
13 words
The device of claim 1 wherein the flexible segment comprises smooth, rounded edges.
Claim 13
Dependent Claim
12 words
The device of claim 1 wherein the flexible segment comprises tapered ends.
Claim 14
Dependent Claim
15 words
The device of claim 1 wherein the vessel and the second vessel are coronary vessels.
Claim 15
Dependent Claim
16 words
The device of claim 13 wherein the vessel and the second vessel are arteries or veins.
Claim 16
Dependent Claim
15 words
The device of claim 1 wherein the flexible segment is comprised of a biocompatible material.
Claim 17
Dependent Claim
15 words
The device of claim 15 wherein the flexible segment is comprised of a bioresorbable material.
Claim 18
Dependent Claim
15 words
The device of claim 15 wherein the flexible segment is comprised of a biodegradable material.
Claim 19
Dependent Claim
21 words
A kit for interconnecting vessels, the kit comprising two or more devices of any one of claims 1 to 17 .
Claim 20
Dependent Claim
18 words
The kit of claim 18 , wherein the two or more devices have a range of different sizes.
Claim 21
Independent Claim
60 words
A method for interconnecting first and second vessels comprising the steps of: providing a flexiable first segment comprising a flow opening therein; constricting the first segment; inserting the first segment into an opening made in the first vessel; and releasing the first segment whereby the flexible segment substantially conforms to and seals with an interior wall of the first vessel.
Claim 22
Independent Claim
60 words
A method for interconnecting first and second vessels comprising the steps of: providing a flexiable first segment comprising a flow opening therein; constricting the first segment; inserting the first segment into an opening made in the first vessel; and releasing the first segment whereby the flexible segment substantially conforms to and seals with an interior wall of the first vessel.
Claim 23
Dependent Claim
36 words
The method of claim 20 further comprising the steps of: inserting a second segment into an opening made in the second vessel; and fluidly interconnecting first and second vessels along the periphery of the flow opening.
Claim 24
Independent Claim
70 words
A method for interconnecting first and second vessels comprising the steps of: providing a first segment comprising a flow opening and having an original configuration and a constricted configuration; inserting the first segment in a constricted configuration into an opening made in the first vessel; and allowing the first segment to assume the original configuration whereby the first segment applies a force against the interior wall of the first vessel.
Claim 25
Independent Claim
70 words
A method for interconnecting first and second vessels comprising the steps of: providing a first segment comprising a flow opening and having an original configuration and a constricted configuration; inserting the first segment in a constricted configuration into an opening made in the first vessel; and allowing the first segment to assume the original configuration whereby the first segment applies a force against the interior wall of the first vessel.
Claim 26
Dependent Claim
36 words
The method of claim 22 further comprising the steps of: inserting a second segment into an opening made in the second vessel; and fluidly interconnecting first and second vessels along the periphery of the flow opening.
