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 having 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;
- a plurality of struts arranged about and configured to cover the one or more cutting blades on the tip portion in a first configuration to protect adjacent tissue from being cut by the one or more cutting blades, the plurality of struts being configured to actuate from the tip portion and extend distally from the tip portion to uncover the one or more cutting blades in a second configuration and the plurality of struts configured to expand radially relative to the tip portion in the second configuration;
- and
- an implantable medical device arranged on the catheter proximally of the tip portion.
2 more elements
A system comprising:
- a delivery sheath having a lumen and a distal tip;
- a catheter including:
- a tip portion arranged at a distal end of the catheter and having one or more cutting blades configured to enlarge an opening in a tissue to create an enlarged opening, and
- a plurality of interconnected struts configured to independently actuate relative to the tip portion and facilitate the one or more cutting blades of the tip portion creating the enlarged opening in the tissue 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 uncover the one or more cutting blades in a second configuration wherein the plurality of interconnected struts are configured to expand radially in a second configuration;
- and
- an implantable medical device arranged on the catheter proximally of the tip portion and configured to deploy within the enlarged opening.
3 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, a tip portion arranged at the distal end of the catheter and including one or more cutting blades, and 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;
- 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 the second configuration;
- extending the tip portion through the openings in the tissue walls of the two anatom ical spaces to create enlarged openings;
- and
- deploying an implantable medical device within the enlarged openings to connect the two anatomical spaces.
2 more elements
A system comprising:
- a delivery sheath having a lumen and a distal tip;
- a catheter including:
- a tip portion arranged at a distal end of the catheter and having one or more cutting blades configured to enlarge an opening in a tissue to create an enlarged opening, and
- a plurality of interconnected struts configured to independently actuate relative to the tip portion and facilitate the one or more cutting blades of the tip portion creating the enlarged opening in the tissue 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 uncover the one or more cutting blades in a second configuration;
- and
- an implantable medical device arranged on the catheter proximally of the tip portion and configured to deploy within the enlarged opening,
- wherein the implantable medical device includes a lumen configured to interconnect two internal spaces of a patient, the distal tip is configured to create openings in the tissue of each of the two internal spaces, and the one or more cutting blades are configured to enlarge the openings in the tissue of each of the internal spaces to create enlarged openings, and
- wherein the two internal spaces include a distal organ and a proximal organ, and the plurality of interconnected struts are configured to:
- actuate distally relative to the tip portion from the proximal organ and into the distal organ through the enlarged openings, expand radially relative to the tip portion, and independently actuate proximally relative to the tip portion to arrange the tissue of the proximal organ adjacent to the tissue of the distal organ to facilitate the one or more cutting blades of the tip portion creating the enlarged openings in the tissue of the proximal organ and the distal organ.
6 more elements
A system comprising:
- a delivery sheath having a lumen and a distal tip;
- a catheter including:
- a tip portion arranged at a distal end of the catheter and having one or more cutting blades configured to enlarge an opening in a tissue to create an enlarged opening, and
- a plurality of interconnected struts configured to independently actuate relative to the tip portion and facilitate the one or more cutting blades of the tip portion creating the enlarged opening in the tissue 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 uncover the one or more cutting blades in a second configuration;
- and
- an implantable medical device arranged on the catheter proximally of the tip portion and configured to deploy within the enlarged opening,
- wherein the delivery sheath is configured to constrain the plurality of interconnected struts, and the plurality of interconnected struts are configured to expand radially in response to the plurality of interconnected struts release from the delivery sheath.
