Systems, devices, and methods for transeptal atrial puncture using an engagement catheter platform
First Claim
1. A multichannel system for engaging a tissue, the system comprising:
- an inducer sheath having a proximal portion and a distal portion and defining a lumen extending therethrough, the inducer sheath configured for insertion into a first lumen of an engagement catheter; and
a dilator defining a first channel and a second channel extending therethrough and a tapered tip at a distal end of the dilator, the dilator sized and shaped for insertion into the lumen of the inducer sheath, wherein the tapered tip is configured to facilitate insertion of the dilator into a mammalian tissue aperture, wherein the mammalian tissue aperture is created using a device positioned within the first channel or the second channel of the dilator.

Abstract
Multichannel systems for engaging a bodily tissue and methods of using the same. In at least one embodiment of an exemplary multichannel system for engaging a tissue of the present disclosure, the system comprises an engagement catheter comprising a proximal end, a distal end, and defining a first lumen and second lumen extending between the proximal end and the distal end, an inducer sheath having a proximal portion and a distal portion, and defining a lumen extending therethrough, the inducer sheath configured for insertion into the second lumen of the engagement catheter, and a dilator defining a first channel and a second channel extending therethrough and a tapered tip at the distal end of the dilator, the dilator sized and shaped for inserted into the lumen of the inducer sheath.

14. A method of engaging a tissue to access a space adjacent thereto, the method comprising the steps of:
-
introducing a multichannel system into a mammalian body so that at least part of the system is adjacent to a targeted tissue, the system comprising; an engagement catheter having a skirt coupled thereto, an inducer sheath having a proximal portion and a distal portion and defining a lumen extending therethrough, the inducer sheath configured for insertion into and positioned within a lumen of the engagement catheter, a dilator positioned within a lumen of the inducer sheath, the dilator defining a first channel and a second channel extending therethrough and having a tapered tip at a distal end of the dilator, the dilator sized and shaped for insertion into the lumen of the inducer sheath, the tapered tip configured to facilitate insertion of the dilator into a mammalian tissue aperture, a needle positioned within a first channel of the dilator, and a catheter positioned within a second channel of the dilator; engaging the targeted tissue using the skirt of the engagement catheter by applying a vacuum to the engagement catheter; piercing the targeted tissue using the needle to create the tissue aperture; and advancing at least part of the inducer sheath and at least part of the dilator into the tissue aperture and into a space behind the targeted tissue. - View Dependent Claims (15, 16, 17, 18)

19. A method of engaging a tissue to access a space adjacent thereto, the method comprising the steps of:
-
introducing a multichannel system into a mammalian body so that at least part of the system is adjacent to a targeted tissue, the system comprising; an inducer sheath having a proximal portion and a distal portion and defining a lumen extending therethrough, the inducer sheath configured for insertion into and positioned within a lumen of the engagement catheter, and a dilator positioned within a lumen of the inducer sheath, the dilator defining a first channel and a second channel extending therethrough and having a tapered tip at a distal end of the dilator, the dilator sized and shaped for insertion into the lumen of the inducer sheath, the tapered tip configured to facilitate insertion of the dilator into a mammalian tissue aperture; engaging the targeted tissue using a distal end of the engagement catheter by applying a vacuum to the engagement catheter; piercing the targeted tissue to create the tissue aperture; and advancing at least part of the inducer sheath and at least part of the dilator into the tissue aperture and into a space behind the targeted tissue; removing the dilator from the inducer sheath; and performing a procedure, the procedure selected from the group consisting of introducing a substance into the space, removing a substance from the space, placing a lead within the mammalian body distal to the tissue aperture, and introducing a device into the space. - View Dependent Claims (20)
