Abstract
Coronary access and delivery systems are provided. A coronary access system can include a coronary sinus guide and a first core. A lateral vein delivery system can include a lateral vein introducer and a second core. The coronary sinus guide, the lateral vein introducer, and the first and second cores may be designed or shaped to access a predetermined position within a heart of a subject. For example, the coronary sinus guide, the lateral vein introducer, and/or the first and second cores can be used in combination to access the predetermined position within the heart of the subject.
Claims21
A coronary access system, comprising:
- a coronary sinus access system, comprising:
- a coronary sinus guide, comprising:
- an elongate member including a proximal end and a distal end, wherein the elongate member comprises:
- a proximal portion;
- a curved medial portion extending distally from the proximal portion, the curved medial portion curving through a substantially circular arc, the proximal portion and the medial portion disposed in a first plane;
- and
- a distal portion extending distally from the curved medial portion in a second plane, wherein the distal end of the elongate member is directed in a proximal direction;
- and
- a first core member disposable within the elongate member, wherein the first core member comprises a nitinol reinforcement member;
- and
- a lateral vein delivery system, comprising:
- a lateral vein introducer;
- and
- a second core member disposable within the lateral vein introducer, wherein the second core member comprises a nitinol reinforcement member.
A coronary access system comprising:
- a coronary sinus access system, comprising:
- a coronary sinus guide;
- and
- a first core member disposable within the coronary sinus guide;
- and
- a lateral vein delivery system, comprising:
- a lateral vein introducer, comprising:
- an elongate member including a proximal end and a distal end, wherein the elongate member comprises:
- a proximal portion;
- an S-shaped portion extending distally from the proximal portion, wherein the S-shaped portion comprises:
- a proximal subportion curving through a first arc;
- and
- a distal subportion extending distally from the proximal subportion, the distal subportion curving through a second arc;
- and
- a distal portion extending distally from the S-shaped portion;
- and
- a second core member disposable within the elongate member, wherein the second core member comprises a nitinol reinforcement member.
A coronary access assembly, comprising:
- a coronary sinus access system comprising:
- a coronary sinus guide comprising:
- a first elongate member including a proximal end and a distal end, wherein the first elongate member comprises:
- a proximal portion;
- a curved medial portion extending distally from the proximal portion, the curved medial portion curving through a substantially circular arc, the proximal portion and the medial portion disposed in a first plane;
- and
- a distal portion extending distally from the curved medial portion in a second plane, wherein the distal end of the first elongate member is directed in a proximal direction;
- and
- a first core member disposable within the coronary sinus guide, wherein the first core member comprises a nitinol reinforcement member;
- and
- a lateral vein delivery system comprising:
- a lateral vein introducer, comprising:
- a second elongate member including a proximal end and a distal end, wherein the second elongate member comprises:
- a proximal portion;
- an S-shaped portion extending distally from the proximal portion;
- and
- a distal portion extending distally from the S-shaped portion;
- and
- a second core member disposable within the coronary sinus guide, wherein the second core member comprises a nitinol reinforcement member.
