Cardiovascular access and device delivery system
A system and method of accessing a heart of a patient is provided. A cardiac access channel is established through an apical wall of the heart to provide direct access through the apical wall to the left ventricle. A vascular access channel is established through the skin to a peripheral blood vessel. A first end of an elongate member is advanced from the outside of the apical wall through the cardiac access channel and into the left ventricle. A second end disposed opposite the first end remains outside the patient. The elongate member is drawn into and through the vascular access channel to externalize the first end of the elongate member while leaving the second end outside the apical wall of the heart.
1. A method of accessing a heart of a patient, comprising:
establishing a cardiac access channel through an apical wall of the heart to provide direct access through the apical wall to the left ventricle;
establishing a vascular access channel through the skin to a peripheral artery;
advancing a first end of an elongate member from the outside of the apical wall through the cardiac access channel and into the left ventricle, a second end disposed opposite the first end remaining outside the patient;
drawing the elongate member into and through the vascular access channel to externalize the first end of the elongate member outside of the peripheral artery while leaving the second end outside the apical wall of the heart;
advancing a venous access catheter from a peripheral venous site through an intra-atrial septum and into a left atrium; and
snaring the elongate member with a snare that extends from the venous access catheter.
2. The method of claim 1 , wherein establishing the cardiac access channel comprises placing an introducer sheath through the heart wall, the introducer sheath comprising a lumen and having an outer profile less than 5 French.
3. The method of claim 2 , further comprising removing the elongate member and the introducer sheath; and dosing the cardiac access channel.
4. The method of claim 3 , wherein closing the cardiac access channel further comprises applying a biological glue in or adjacent to the cardiac access channel.
5. The method of claim 4 , further comprising advancing a balloon catheter to the epicardium and delivering the biological glue through the balloon directly onto the epicardium.
6. The method of claim 3 , wherein closing the cardiac access channel further comprises suturing the myocardium to compress the tissue around the cardiac access channel.
7. The method of claim 3 , wherein closing the cardiac access channel further comprises delivering a compression member to the epicardium to apply pressure to the tissue at or around the apical wall.
8. The method of claim 1 , further comprising:
advancing an arterial-side snare into the vasculature through the peripheral artery; and
drawing the elongate member through the peripheral artery using the arterial-side snare to externalize the first end of the elongate member.
9. The method of claim 8 , further comprising:
tensioning the elongate member to establish a delivery platform between a distal portion of the venous access catheter and the cardiac access channel.
10. The method of claim 9 , further comprising delivering a prosthetic mitral valve at a level of a mitral valve annulus along the delivery platform after tensioning the elongate member.
11. A method of accessing a heart of a patient, comprising:
establishing a cardiac access channel through an apical wall of the heart to provide direct access through the apical wall to a left ventricle;
advancing a first end of a elongate member through the cardiac access channel and into the left ventricle, wherein a second end of the elongate member remains outside the patient;
advancing a distal end portion of a venous access catheter from a peripheral venous access site across an intra-atrial septum and into a left atrium;
drawing the first end of the elongate member into and through the venous access catheter to externalize the first end through the peripheral venous access site; and
drawing a prosthesis from the venous access catheter by applying tension to the elongate member.
12. The method of claim 11 , further comprising:
tensioning the elongate member between the distal end portion and the cardiac access channel.
13. The method of claim 11 , wherein the elongate member passes through a lumen of the prosthesis.
14. The method of claim 11 , further comprising:
deploying the prosthesis at the level of the mitral valve annulus.
15. A method of accessing a heart of a patient, comprising:
establishing a cardiac access channel through an apical wall of the heart to provide direct access through the apical wall to a left ventricle;
advancing a first end of a elongate member through the cardiac access channel and into the left ventricle, wherein a second end of the elongate member remains outside the patient;
advancing a distal end portion of a venous access catheter from a peripheral venous access site across an intra-atrial septum and into a left atrium;
drawing the first end of the elongate member into and through the venous access catheter to externalize the first end through the peripheral venous access site;
advancing a second catheter over the elongate member from the peripheral venous access site into the left atrium; and
drawing a prosthesis from the second catheter by applying tension to the elongate member.
