Abstract
Medical devices, systems and methods for occluding a left atrial appendage of a heart with an implant are provided. In one embodiment, a medical device system includes a sheath for delivering the implant. The sheath includes, at a distal portion of the sheath, first and second deflectable portions that are each independently deflectable relative to first and second pivot locations, respectively. With this arrangement, at least one of the first and second pivot locations are adjustable along a longitudinal length of the distal portion of the sheath.
Claims20
A medical device system for occluding a left atrial appendage of a heart, comprising;
- a delivery catheter with a medical device coupled adjacent a delivery catheter distal end of the delivery catheter;
- and
- a sheath having a sheath handle with a pivot location member, the pivot location member moveable linearly distal and linearly proximal relative to the sheath handle, the sheath extending with a wall between a distal end and a proximal end with a central lumen and central axis defined in the sheath along a longitudinal length of the sheath such that the medical device and delivery catheter are advanceable through the central lumen of the sheath, the sheath defining a concentric lumen therein so as to extend along the wall, the sheath being deflectable with a first deflectable portion relative to a first pivot location along a distal portion of the sheath and the sheath being deflectable with a second deflectable portion relative to a second pivot location along the distal portion of the sheath;
- wherein, upon advancement of the sheath to the left atrial appendage of the heart, at least one of the first pivot location and the second pivot location of the first and second deflectable portions, respectively, is adjustable with longitudinal movement along the longitudinal length of the distal portion of the sheath;
- wherein the at least one of the first and second pivot locations is moveable distally with linear movement of the pivot location member to a distal position;
- and
- wherein the at least one of the first and second pivot locations is moveable proximally with linear movement of the pivot location member to a proximal position.

- wherein, upon advancement of the sheath to the left atrial appendage of the heart, at least one of the first pivot location and the second pivot location of the first and second deflectable portions, respectively, is adjustable with longitudinal movement along the longitudinal length of the distal portion of the sheath;
- wherein the at least one of the first and second pivot locations is moveable distally with linear movement of the pivot location member to a distal position;
- and
- wherein the at least one of the first and second pivot locations is moveable proximally with linear movement of the pivot location member to a proximal position.
