Abstract
Aspects of the present disclosure are directed toward apparatuses, systems, and methods for stent access and device delivery. In certain instances, the apparatuses, systems, and methods may include a plurality of struts arranged about the one or more cutting blades on a tip portion.
Claims20
A delivery system comprising:
- a catheter including a distal end, a proximal end, and a body portion extending between the distal end and the proximal end;
- a tip portion at the distal end of the catheter and including one or more cutting blades, the tip portion configured to create openings in a tissue wall of two internal spaces, the one or more cutting blades configured to enlarge the openings in tissue of each of the two internal spaces to create enlarged openings;
- a plurality of struts arranged about the one or more cutting blades in a first configuration, the plurality of struts being separable distally from the tip portion by being translated distally from the tip portion to expose the one or more cutting blades in a second configuration;
- and
- a leading atraumatic end connected to the plurality of struts and positioned at a terminal distal end of the delivery system in the first configuration,
- wherein a distal space is defined between the distal end of the catheter and a proximal end of the leading atraumatic end when the plurality of struts are translated distally in the second configuration.

A delivery system comprising:
- a delivery sheath including a lumen and a distal tip,
- a catheter including a distal end, a proximal end, and a body portion extending between the distal end and the proximal end;
- a tip portion arranged at the distal end of the catheter and including one or more cutting blades;
- and
- a plurality of interconnected struts arranged about the one or more cutting blades on the tip portion in a first configuration, the plurality of interconnected struts being configured to actuate from the tip portion and translate extend distally away from the tip portion to expose the one or more cutting blades in a second configuration, the plurality of interconnected struts being constrained by the delivery sheath,
- wherein, in the first configuration, the plurality of interconnected struts cover the one or more cutting blades, and
- wherein a distal space is defined between the distal end of the catheter and a proximal end of the plurality of interconnected struts in the second configuration.
4 more elements
A method of connecting two anatomical spaces of a patient, the method comprising:
- arranging a delivery system at a target location, the delivery system including a catheter having a distal end, a proximal end, and a body portion extending between the distal end and the proximal end, an tip portion at a distal end of the catheter including one or more cutting blades, a plurality of struts arranged about the one or more cutting blades and configured to cover the one or more cutting blades in a first configuration to protect adjacent tissue from being cut by the one or more cutting blades, and a leading atraumatic end connected to the plurality of struts and positioned at a terminal distal end of the delivery system in the first configuration;
- actuating the plurality of struts distally relative to the tip portion through openings in tissue walls of the two anatomical spaces such that the plurality of struts expands radially relative to the tip portion in a second configuration;
- extending the tip portion through the openings in the tissue walls of the two anatomical spaces to create enlarged openings;
- and
- connecting the two anatomical spaces.
