Publication number: 20240151116Abstract: A hanger assembly includes: a main body; a lock ring coupled to the main body and configured to expand radially outward into a profile on an inner diameter of the wellhead; and an actuator, wherein the actuator is capable of transferring an axial force from the actuator into outward radial expansion of the lock ring toward the profile on the inner diameter of the wellhead. An interface between the actuator and the lock ring is shaped such that: axially downward movement of the actuator from a starting position to an intermediate position actuates the lock ring into the profile; and axially downward movement of the actuator from the intermediate position to a pre-load position applies a pre-load to the hanger assembly.Type: ApplicationFiled: January 10, 2024Publication date: May 9, 2024Inventors: Andrew B. Mitchell, Chris D. Bartlett, David Scantlebury, Rick Murphy, Fife B. Ellis, Gregory Norwood

Patent number: 11576774Abstract: The disclosure provides insertion tools and articles that facilitate entry of a medical device, such as a balloon catheter, into the body. In embodiments the insertion tools have an elongate hollow body (50) that is able to protect a portion of a medical device, such as a balloon of a balloon catheter, during an insertion procedure. In one embodiment the insertion tool has an elongate hollow body (131), a tapered distal end (135), and a locking mechanism (133) at the proximal end which can secure a portion of a balloon catheter. An opening at the distal end can allow passage of the balloon in a folded uninflated state.Type: GrantFiled: June 29, 2020Date of Patent: February 14, 2023Assignee: Surmodics, Inc.Inventors: Bruce M. Jelle, Joram Slager, Joseph S. McGonigle, Rick Murphy, Andrew G. Bach, Teryl L. Woodwick Sides, Ambereen Angamuthu, Sean Lundquist, Gary Opperman, Nathan A. Lockwood

Patent number: 11459843Abstract: A space-out mechanism that may be used in a tubing hanger system to install a tubing hanger and rigidize the tubing hanger and a casing hanger within a wellhead housing in a single trip is provided. The space-out mechanism may include two pieces that are configured to rotate against each other such that the axial length of the space-out mechanism can be adjusted to remove any axial gaps created in the installation of the tubing hanger or rigidizing of the tubing hanger and casing hanger within the wellhead housing. The two pieces of the space-out mechanism may include a ramp ring and a piston. The ramp ring and piston may each have ramp surfaces that rotate and bear against each other until the system is rigidized.Type: GrantFiled: December 10, 2020Date of Patent: October 4, 2022Assignee: Dril-Quip, Inc.Inventors: Chris D. Bartlett, David Scantlebury, Rick Murphy, Andrew Mitchell, Fife B. Ellis, Gregory Norwood

Patent number: 11123459Abstract: Drug delivery coatings and devices including the same are described herein. The drug delivery coating has a first coated layer with non-ionic polymer and photogroups, a second coated layer with acid polymer in contact and hydrogen bonded with the first layer, particles with hydrophobic therapeutic agent, and cationic agent. The coating can be provided on a balloon catheter, and the particles and cationic agent can be transferred to tissue during a medical procedure, such as an angioplasty procedure, for a therapeutic effect.Type: GrantFiled: December 14, 2017Date of Patent: September 21, 2021Assignee: Surmodics, Inc.Inventors: Joram Slager, Rick Murphy

Patent number: 10918835Abstract: Embodiments herein include delivery systems for active agent coated balloons and related methods. In an embodiment, a delivery system can include a tunneling sheath and a balloon catheter. The tunneling sheath can include a tubular shaft having an outer diameter and defining a lumen. The tunneling sheath can include a proximal collar defining a lumen. The balloon catheter can include a balloon catheter shaft disposed within the tubular shaft. The balloon catheter shaft can include a lumen for the passage of a fluid therein. The balloon catheter can include an expandable balloon disposed on the balloon catheter shaft. The balloon catheter shaft can include an active agent layer disposed on the expandable balloon. The position of the expandable balloon can be configured to be stationary relative to the tubular shaft as the delivery system is passed through a blood vessel of a patient. Other embodiments are also included herein.Type: GrantFiled: March 23, 2017Date of Patent: February 16, 2021Assignee: Surmodics, Inc.Inventor: Rick Murphy
