Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
59 words
An implantable medical device for at least partially obstructing a septal defect, comprising: an obstruction mechanism; and a non-linear elongated tissue-puncturing end connected to the obstruction mechanism, wherein the non-linear elongated tissue-puncturing end includes a coil having a tissue engaging section and a puncturing member, and wherein the tissue engaging section interconnects the obstruction mechanism and the puncturing member.
Claim 2
Dependent Claim
59 words
An implantable medical device for at least partially obstructing a septal defect, comprising: an obstruction mechanism; and a non-linear elongated tissue-puncturing end connected to the obstruction mechanism, wherein the non-linear elongated tissue-puncturing end includes a coil having a tissue engaging section and a puncturing member, and wherein the tissue engaging section interconnects the obstruction mechanism and the puncturing member.
Claim 3
Dependent Claim
106 words
An implantable device, deliverable via a vascular catheter, of a size and overall flexibility to lodge in an area of tissue located proximate a septal defect, and suitable for at least partially obstructing the septal defect, comprising: an elongated delivery member having a distal end; an obstruction mechanism comprising a ring-shaped structure having an interior portion and a connection to a coil that includes a puncturing member; a material covering that substantially fills the interior portion of the ring-shaped structure; and a connection between the distal end of the elongated delivery member and the obstruction mechanism, wherein the connection enables the obstruction mechanism to be rotated.
Claim 4
Dependent Claim
106 words
An implantable device, deliverable via a vascular catheter, of a size and overall flexibility to lodge in an area of tissue located proximate a septal defect, and suitable for at least partially obstructing the septal defect, comprising: an elongated delivery member having a distal end; an obstruction mechanism comprising a ring-shaped structure having an interior portion and a connection to a coil that includes a puncturing member; a material covering that substantially fills the interior portion of the ring-shaped structure; and a connection between the distal end of the elongated delivery member and the obstruction mechanism, wherein the connection enables the obstruction mechanism to be rotated.
Claim 5
Dependent Claim
40 words
The implantable device of claim 2 , wherein the connection comprises an engagement between a first threaded member disposed on the distal end of the elongated delivery member and a functionally corresponding second threaded member disposed on the material covering.
Claim 6
Dependent Claim
27 words
The implantable device of claim 2 , wherein the connection comprises a frictional engagement between the distal end of the elongated delivery member and the material covering.
Claim 7
Dependent Claim
21 words
The implantable device of claim 2 , wherein the material covering is constructed of a material that is a therapeutic agent.
Claim 8
Dependent Claim
17 words
The implantable device of claim 2 , wherein the material covering is constructed of a bioactive material.
Claim 9
Dependent Claim
20 words
The implantable device of claim 6 , wherein the bioactive material is a biologically absorbable material that encourages cell growth.
Claim 10
Independent Claim
121 words
A method for at least partially obstructing a septal defect in a heart by implanting a medical device, comprising: placing a distal end of a catheter in a location proximate the septal defect; utilizing an elongated delivery member to push an obstruction device through the catheter until a puncturing member portion of the obstruction device extends from the distal end of the catheter; puncturing, with the puncturing member, an area of tissue proximate the septal defect; rotating the obstruction device such that a non-linear tissue engaging section of the obstruction device, which is connected to the puncturing member, becomes substantially embedded in the area of tissue proximate the septal defect; and removing the catheter and elongated delivery member from the heart.
Claim 11
Independent Claim
121 words
A method for at least partially obstructing a septal defect in a heart by implanting a medical device, comprising: placing a distal end of a catheter in a location proximate the septal defect; utilizing an elongated delivery member to push an obstruction device through the catheter until a puncturing member portion of the obstruction device extends from the distal end of the catheter; puncturing, with the puncturing member, an area of tissue proximate the septal defect; rotating the obstruction device such that a non-linear tissue engaging section of the obstruction device, which is connected to the puncturing member, becomes substantially embedded in the area of tissue proximate the septal defect; and removing the catheter and elongated delivery member from the heart.
Claim 12
Dependent Claim
30 words
The method of claim 8 , wherein rotating the obstruction device comprises: maintaining a frictional engagement between the catheter and a circumference of the obstruction device; and rotating the catheter.
Claim 13
Dependent Claim
30 words
The method of claim 8 , wherein rotating the obstruction device comprises: maintaining an engagement between the elongated delivery member and the obstruction device; and rotating the elongated delivery member.
Claim 14
Dependent Claim
38 words
The method of claim 10 , wherein maintaining an engagement between the elongated delivery member and the obstruction device comprises: maintaining a frictional engagement between the elongated delivery member and a material covering portion of the obstruction device.
Claim 15
Dependent Claim
59 words
The method of claim 10 , wherein maintaining an engagement between the elongated delivery member and the obstruction device comprises: maintaining a threaded engagement between a first threaded member disposed on the distal end of the elongated delivery member and a second threaded member that functionally corresponds to the first threaded member and is disposed on the obstruction device.
Claim 16
Dependent Claim
47 words
The method of claim 12 , wherein removing the catheter and elongated delivery member from the heart comprises: disengaging the first threaded member from the second threaded member; removing the elongated delivery member from the catheter and from the heart; and removing the catheter from the heart.
Claim 17
Dependent Claim
50 words
The method of claim 10 , wherein removing the catheter and elongated delivery member the heart comprises: disengaging the elongated delivery member from the obstruction device by severing a joint therebetween; removing the elongated delivery member from the catheter and from the heart; and removing the catheter from the heart.
