Abstract
The present disclosure relates to novel and advantageous systems and methods for deploying a surgical tool or guidewire. Particularly, the present disclosure relates to novel and advantageous systems and methods for deploying a surgical tool for use in changing the shape of portions of luminal systems. More particularly, the present disclosure relates to novel and advantageous systems and methods including an access catheter to direct an implement, such as a guide wire, off axis into a wall of a vessel or a wall of a tissue structure.
Claims19
An access catheter to access an target location inside a tissue structure, comprising:
- an outer elongate body having a proximal end, a distal end and defining a longitudinal axis of the access catheter;
- and
- a transverse accessor body having a proximal end and a distal end, wherein the transverse accessor body is slidably coupled to at least a portion of the outer elongate body, and further wherein a distal end region of the transverse accessor body includes a shape memory attribute that causes the distal end region of the transverse accessor body to bend away from the outer elongate body to bring the distal end of the transverse accessor body into an alignment that is oblique or orthogonal with respect to the longitudinal axis of the outer elongate body.
An access catheter to access an target location inside a tissue structure, comprising:
- an elongate body having a proximal end and a distal end;
- and
- a marker disposed on the elongate body to permit a user to detect its rotational orientation with respect to anatomy under at least one imaging modality.
