Description
- This application is a Continuation of U.S. patent application Ser. No. 15/891,653, filed on Feb. 8, 2018, which claims the benefit of U.S. Provisional Patent Application No. 62/458,527 filed Feb. 13, 2017, the contents of which are herein incorporated by reference in their entirety.
- The present disclosure relates to a percutaneous interventional device, and particularly to a sinus venosus atrial septal defect treatment device and method.
- Typically, in a normal functioning heart, the left atrium receives the oxygenated blood from each of the four pulmonary veins. After receiving it, the oxygenated blood flows into the left ventricle, where the oxygenated blood is subsequently pumped to the brain, organs, and tissues of the body. The right atrium, on the other hand, receives the deoxygenated blood from the superior vena cava and inferior vena cava and other cardiac veins and then pumps deoxygenated blood into the right ventricle, which subsequently pumps the deoxygenated blood into the pulmonary system to replenish its oxygen supply. Normally, the left atrium and the right atrium are separated by a septum known as the interatrial septum that prevents the oxygenated blood in the left atrium from mixing with the deoxygenated blood in the right atrium.
- However, if the interatrial septum fails to properly develop an atrial septal defect (ASD) can result. An ASD is a hole in the interatrial septum that allows the oxygenated blood to mix with the deoxygenated blood. If the ASD is left untreated, it can lead to lower than normal oxygen in the atrial blood that is pumped from the left atrium to the brain, organs, and tissues of the body, which can eventually lead to the development of a cardiac arrhythmia, decompression sickness, Eisemnenger's syndrome, paradoxical embolus, and even migraines.
- There are four types of ASDs, an ostium secundum ASD, an ostium primum ASD, a sinus venosus ASD, and a coronary sinus ASD, the ostium secundum ASD being the most prevalent. While ostium secundum and ostium primum ASDs account for approximately 70% and 20%, respectively, of the total number of ASDs, sinus venosus ASDs account for approximately 10% of the total number of ASDs. The most common type of sinus venosus ASD occurs at the junction of right atrium and the superior vena cava, which is the location where the pulmonary veins enter the heart. In other words, one of the four pulmonary veins, such as the right upper pulmonary vein, drains into the right atrium instead of the left atrium. While ostium secundum ASD can be treated percutaneously, as well as surgically, to date, there is no percutaneous interventional procedure for treating sinus venosus ASDs.
- Thus an atrial septal defect treatment device and method solving the aforementioned problems is desired.
- The sinus venosus atrial septal defect (“ASD”) treatment device includes a flexible proximal portion at a first end, a flexible distal portion at an opposing second end, and a flexible central portion between the proximal portion and the distal portion. The device has a hollow lumen and is open at opposing ends thereof The opening at the first end is expandable from a first diameter when the device is being deployed through the body of the left atrium, to a second, larger diameter when the device is positioned within the right upper pulmonary vein and expanded with a balloon catheter. The proximal portion includes a plurality of receiving plates with respective keyholes configured to receive a corresponding key from a balloon portion of a balloon catheter. The distal portion includes a self-expandable edge portion or skirt. The skirt can include a septal augmenter rim configured for securing the device to the left atrium side of the interatrial septum.

- Referring to
FIGS. 1A-7B , an atrial septaldefect treatment device 100, configured for the percutaneous closure of a sinus venosus atrial septal defect for diversion of anomalous pulmonary drainage into the left atrium, is generally illustrated. Thedevice 100 has a generally tubular or funnel shaped configuration. Afirst end 122 of thedevice 100 can have a diameter that is less than a diameter of asecond end 124 of thedevice 100. Thedevice 100 can be inserted in the right upper right pulmonary vein PV. Thesecond end 124 of thedevice 100 is configured to expand in a skirt-like configuration once thedevice 100 is positioned in the right upper right pulmonary vein PV. In this manner, thedevice 100 closes the upper sinus venosus hole and diverts anomalous pulmonary venous drainage into the left atrium, as illustrated inFIGS. 7A and 7B . - The
device 100 includes a flexibleproximal portion 110 at thefirst end 122, a flexibledistal portion 130 at the opposingsecond end 124, and a flexiblecentral portion 120 between theproximal portion 110 and thedistal portion 130. Thedevice 100 has a hollow lumen and is open atopposing ends - The
proximal portion 110 can have any suitable shape, such as a generally cylindrical shape. Theproximal portion 110 includes a self-expandingmesh 112 that can be formed from any suitable interlocking medical grade material, such as Nitinol. Anopening 119 at thefirst end 122 is expandable from a first diameter D1 (FIG. 1A ), such as when thedevice 100 is being deployed through the body of the left atrium, to a second, larger diameter D1′ (FIGS. 1B and 1C ), such as when thedevice 100 is positioned within the right upper pulmonary vein and expanded using a balloon catheter. The second diameter can range, for example, from about 10 mm to about 15 mm. Theproximal portion 110 can have any suitable length L1, such as a length ranging from about 15 mm to about 20 mm. In an embodiment, theproximal portion 110 can include a plurality of attachment receiving structures or receivingplates 114 for receiving a corresponding attachment device or key. For example, each of the receivingplates 114 can include an aperture orkeyhole 116. Thekeyhole 116 can include a circularfirst portion 117 a and rectangularsecond portion 117 b extending from thefirst portion 117 a. Thekeyhole 116 is configured to receive a corresponding key from a balloon portion of a balloon catheter, as will be further described in detail below. The plurality ofplates 114 can include threeplates 114, such as metal plates, vertically positioned around theproximal portion 110 of thedevice 100. - The
central portion 120 of thedevice 100 can have any suitable length L2, such as a length ranging from approximately 10 mm to approximately 15 mm. Thecentral portion 120 can include a plurality of flexible, e.g., self-expandable,metal rods 126. The metal rods can be spaced from each other. Eachmetal rod 126 can be formed from any suitable medical grade material, such as Nitinol, and may be covered by any type of suitable medical grade material, such as polytetrafluoroethylene. Thecentral portion 120 also includes anaperture 128 that remains uncovered for side branch stenting in case of the need for extra support or for bifurcating drainage. The edge or area immediately surrounding theaperture 128 may be radio-opaque. Theaperture 128 can have any suitable diameter, such as a diameter of approximately 5 mm. - The
distal portion 130 can have any suitable length L3, such as 10 mm. Thedistal portion 130 includes a self-expandable edge portion orskirt 132 formed from a plurality of interlockingmetal rods 134, such as Nitinol rods, that can be arranged in a grid formation or in a mesh formation. Each of themetal rods 134 may be covered, such as partially covered, with polytetrafluoroethylene. For example, an end of eachmetal rod 134 attached to thecentral portion 120 may be covered with polytetrafluoroethylene and an opposing end of eachmetal rod 134 may be left bare (i.e. uncovered). - The
skirt 132 of the opposingdistal portion 130 can have any suitable diameter, such as a first diameter D3 when collapsed and positioned on theballoon 202 of theballoon catheter 200 and a second larger diameter D3′ (FIG. 1C ) when expanded to occlude the sinus venosus atrial septal defect (e.g. opening) from the left atrium LA side of the interatrial septum IS. When the sinus venosus atrial septal defect (e.g. opening) is occluded in this manner, oxygenated blood can flow directly into the left atrium LA of the heart H without escaping into the right atrium RA. Theskirt 132 can include an expandableseptal augmenter rim 136. Theseptal augmenter rim 136 is configured for securing thedevice 100 to the left atrium LA side of the interatrial septum IS once theseptal augmenter rim 136 is inserted into the left atrium LA side of the interatrial septum IS. Once expanded, theseptal augmenter rim 136 can anchor the opposingdistal portion 130 of thedevice 100 within the left atrium LA side of the interatrial septum IS. - The device may be positioned in the right upper right pulmonary vein PV using a balloon catheter 202 (
FIG. 3 andFIG. 4 ). Aballoon portion 202 of theballoon catheter 200 includes attachment structures or locking plates with one ormore keys 118, e.g., radio-opaque mushroom shaped keys (FIG. 4 ) configured for insertion inrespective keyholes 116 of thedevice 100. Eachkeyhole 116 is suitable for receiving acorresponding key 118, such as a mushroom shaped key with circular head and stem extending therefrom. Theballoon catheter 205 is inserted into thedevice 100 outside of the body, via thedistal portion 130 of thedevice 100, to secure thedevice 100 thereto. Each key 118 fits into acorresponding keyhole 116 of eachplate 114. Clockwise rotation of the catheter moves the stem of the mushroom key to fit in the keyholesecond portion 117 b so as to secure thedevice 100 to theballoon 202 of theballoon catheter 200 to facilitate delivering thedevice 100 within the pulmonary vein PV of the heart H. It should be understood that the key/keyhole attachment described herein is provided as a non-limiting example. The attachment structures can include any structure which allows the catheter to engage thedevice 100. - By way of operation, initially a trans-femoral vein approach is used by advancing a
first sheath 215, e.g., a large caliber deflectable/steerable sheath having a size ranging from 9Fr to 12Fr, into the femoral artery and toward the interatrial septum IS (FIG. 6 ). This is followed by making a trans-septal opening 600 with a trans-septal needle (not shown), just below the sinus venosus atrial septal defect (ASD) in the interatrial septum IS separating the right atrium RA from the left atrium LA (FIG. 7 ). - The trans-
septal opening 600 allows for vascular access, as well as access into the target pulmonary vein PV. In this manner, pulmonary vein PV may be targeted via the inferior vena cava IVC, as illustrated by arrow A inFIG. 6 . Thesteerable sheath 215 is configured for supporting and providing access into the pulmonary vein PV from the left atrium LA, via the interatrial septum IS, as illustrated inFIG. 6 . Such steerable sheaths are well known in the art and can include the Agilis™ NXT Steerable Introducer from St. Jude, the FlexCath Advance Steerable Sheath from Medtronic, and the Vado® Steerable Sheath from Abbott. - A
guide wire 205, e.g., an elongated stiff “J” tip guide wire, is then advanced through thesteerable sheath 215 to the coronary arteries. Thesteerable sheath 215 is used to properly position theguide wire 205 within the target pulmonary vein PV. Once theguide wire 205 is properly positioned, asecond sheath 210 including atip 212 with a radio-opaque marker is inserted within thesteerable sheath 215, over theguide wire 205, and into the target pulmonary vein PV via the left atrium LA. - Once the
second sheath 210 is properly positioned within the target pulmonary vein PV, theballoon catheter 200, secured to thedevice 100 via lockingsystem 300, is then inserted through thesecond sheath 210 and over theguide wire 205 until theballoon catheter 200 reaches the target pulmonary vein PV. Theballoon 202 is then inflated, such as by filling theballoon 202 with fluid, such as saline, as is known in the art. By inflating theballoon 202, theproximal portion 110 of thedevice 100 expands within the target pulmonary vein PV so as to fit securely within the target pulmonary vein PV. Once the balloon is inflated, thecatheter 200 is disengaged (e.g. unlocked) from thedevice 100, such as by twisting thecatheter 200 to remove thekeys 118 from thekeyholes 116. - After the
balloon 202 is disengaged from theproximal portion 110 of thedevice 100, thesecond sheath 210 and theballoon catheter 200 are retracted along theguide wire 205 back through the atrial septal defect. As theballoon catheter 200 and thesecond sheath 210 are retracted, the self-expandable skirt 132 ofdistal portion 130 of thedevice 100 expands on the left atrium LA side of the interatrial septum IS, as illustrated inFIGS. 7A and 7B . After expanding within the left atrium LA side of the interatrial septum IS, theseptal augmenter rim 136 may anchor thedistal portion 136 within the left atrium LA side of the interatrial septum IS to prevent oxygenated blood from flowing into the right atrium RA. Once theproximal portion 110 of thedevice 100 is properly positioned within the target pulmonary vein PV and the opposingdistal portion 130 of thedevice 100 is properly positioned on the left atrium LA side of the interatrial septum IS, the oxygenated blood may flow from the lungs, through the target pulmonary vein PV and into the left atrium LA of the heart H. - It is to be understood that the disclosed technology is not limited to the embodiments described above, but encompasses any and all embodiments within the scope of the following claims
