Patent number: 9861782Abstract: A variable stiffness catheter having two concentric coils. A first coil is fixed with relation to the body of the catheter and a second coil is able to rotate in the space between adjacent turns of the first coil. The second coil translates axially in response to being rotated. When the second coil is advanced to its distal position, the stiffness is maximized. When the second coil is retracted proximally, the stiffness of the coil is reduced.Type: GrantFiled: April 11, 2016Date of Patent: January 9, 2018Assignee: Cook Medical Technologies LLCInventors: Trevor Plassman, Logan Michael Cage

Patent number: 9498226Abstract: An embolic coil delivery system includes a flexible elongate body having a distal segment. An embolic coil is loaded on the flexible elongate body at the distal segment and contacts an outer surface of the flexible elongate body. The embolic coil delivery system also includes a delivery catheter sized to advance over the flexible elongate body during an embolic coil delivery procedure, wherein a distal segment of the delivery catheter contacts the embolic coil during the embolic coil delivery procedure.Type: GrantFiled: August 28, 2012Date of Patent: November 22, 2016Assignee: Cook Medical Technologies, LLCInventors: Logan Michael Cage, Sarah Elizabeth Reeves

Patent number: 9364589Abstract: In a method for making a wire guide, a fluoropolymer coating is removed from a distal section of an FP coated core wire to expose a metallic portion. A polymer coating is applied to a proximal section of the FP coated core wire such that the polymer coating overlays at least a portion of the FP coating, and to the distal section of the FP coated core wire including the exposed metal portion. The polymer coating is removed from the FP coating to form the wire guide having a proximal portion with the FP coating and a distal portion with the polymer coating. A hydrophilic coating may be applied to the distal portion over the polymer coating.Type: GrantFiled: January 9, 2015Date of Patent: June 14, 2016Assignee: COOK MEDICAL TECHNOLOGIES LLCInventors: Logan Michael Cage, James Cameron Elsesser

Publication number: 20160157872Abstract: A lumen re-entry system includes a catheter having an elongate tubular body defining a wire lumen extending from an open proximal end of the elongate tubular body to a distal opening through the elongate tubular body. An abrasion resistant tubular liner is positioned within the wire lumen and has a fixed position relative to the elongate tubular body. The abrasion resistant tubular liner defines a reduced wire lumen extending from an open proximal end of the abrasion resistant tubular liner to an open distal end of the abrasion resistant tubular liner. A puncture wire is configured for axial movement through the reduced wire lumen and has an angled distal segment terminating in a puncture tip. The angled distal segment is oriented at an angle between about 10 degrees to about 90 degrees relative to a central longitudinal axis of the puncture wire.Type: ApplicationFiled: February 16, 2016Publication date: June 9, 2016Inventors: Logan Michael Cage, David Christian Lentz, Jeremy Schaeffer

Patent number: 9358070Abstract: A medical device package includes an elongate tubular holder having a first and a second detachable tip, and a medical device positioned within a cavity and contained within the holder via the first and second detachable tips. The medical device has a self-shaping bias and is loaded in opposition to the bias via contact with an inner surface of the holder defining the cavity. The first and second detachable tips may include snap-off tips, such that upon detachment the cavity is opened for removing the medical device. Related methodology is disclosed.Type: GrantFiled: January 21, 2013Date of Patent: June 7, 2016Assignee: Cook Medical Technologies LLCInventors: Logan Michael Cage, Elizabeth Anne Theobald, Kurt J. Tekulve, Steve Harris, Ryan Koontz

Patent number: 8473034Abstract: A system and method for monitoring the placement of a feeding tube in the jejunum of a patient includes a system comprising a feeding tube and a tubular member received in a passageway extending through the feeding tube. The tubular member is sized relative to the feeding tube such that an echogenic distal length of the tubular member extends distal to the open distal end of the feeding tube. The distal end of the assembly is advanced into the small intestine of the patient, and a negative pressure is drawn through an opening in the distal length of the tubular member to draw the tubular member distal length into juxtaposition with a wall of the small intestine. The position of the assembly in the small intestine may be observed in real time via ultrasound visualization of the echogenic portion.Type: GrantFiled: March 4, 2011Date of Patent: June 25, 2013Assignee: Cook Medical Technologies LLCInventors: Logan Michael Cage, Peter William Sargent, Jr.
