Patent number: 9981115Abstract: An introducer sheath includes an inner liner having a passageway extending longitudinally therethrough, a coil positioned over the inner liner, and an outer jacket positioned over the liner and the coil. The outer jacket is bonded to the inner liner between the coil turns. The coil turns have a cross-section comprising opposing end portions, and a center portion disposed between the opposing end portions. The center portion has a thickness not exceeding about one-third of a thickness of the end portions for reducing a bending modulus of the coil, and the end portions have a generally curved outer surface. At least a distal end portion of the outer jacket has a durometer between about 70 and 90 on the Shore D scale.Type: GrantFiled: June 21, 2016Date of Patent: May 29, 2018Assignee: COOK MEDICAL TECHNOLOGIES LLCInventors: James C. Merk, Melissa Dawn Baker, Mark J. Hiatt

Patent number: 8568436Abstract: A dilator (10) for creating tracheostomies in one pass. Dilator (10) includes a generally linear shaft (12) extending from a proximal end (14) and beginning at a distance therefrom, gradually and continuously through a curved distal portion (16) of continuously decreasing diameter (from about 38 french) to a distal tip portion (18) of small diameter of about 12 french at distal end (20). The outer surface of the insertable portion is treated or hydrophilically coated to minimize friction, and the gradual taper gradually widens the tracheal entrance opening (44) between tracheal rings (46,48) with minimal trauma. The wall thickness gradually decreases from the linear shaft (12) to the soft distal tip portion (18). The continuing curve of the distal portion (16) enables the increasingly longer inserted portion of the dilator to remain situated in the trachea (50) during insertion and for the distal tip portion to clear the posterior tracheal wall.Type: GrantFiled: August 29, 2003Date of Patent: October 29, 2013Assignee: Cook Medical Technologies LLCInventors: Pasquale Ciaglia, Melodee Deckard, Mark J. Hiatt, Joseph P. Lane

Patent number: 8123770Abstract: An integrally formed angioplasty cutting device for balloon angioplasty of a stenotic lesion in a body vessel. The device comprises a distal collar and a proximal collar. The device further comprises at least one strut integrally formed with the distal collar and the proximal collar. At least one of the collars has a slot formed therethrough defining a C-shaped configuration. The strut is configured to be disposed at the stenotic lesion to engage the stenotic lesion for dilatation of the body vessel during angioplasty.Type: GrantFiled: November 1, 2006Date of Patent: February 28, 2012Assignee: Cook Medical Technologies LLCInventors: Kian Olsen, Mark J. Hiatt, Michael W. Hardert

Patent number: 8052650Abstract: A feeding device configured for insertion into the gastrointestinal tract of a patient, and dynamic movement through the gastrointestinal tract toward the jejunum. The device includes an elongate tubular member having a plurality of distal projections disposed on an exterior surface thereof. The projections extend radially outwardly from the exterior surface of the tubular member a distance sufficient to engage an interior surface of the gastrointestinal tract during peristaltic contractions therein, and are configured to promote ingress of the device in response to the contractions. At least some of the projections are soluble under bodily conditions at the gastrointestinal tract, thereby facilitating removal of the feeding device.Type: GrantFiled: April 15, 2008Date of Patent: November 8, 2011Assignee: Cook Medical Technologies LLCInventors: Ronan T. Young, Mark J. Hiatt, Andrew K. Hoffa

Publication number: 20090264860Abstract: An infusion catheter system includes an elongated catheter body and an inner elongated cannula body. The catheter body has a sidewall perforated with a plurality of side ports and the cannula body may have an outlet opening in a distal end. The side ports of the catheter body are selectively in fluid communication with the outlet opening of the cannula by moving the cannula between a first and second position within the catheter body.Type: ApplicationFiled: March 4, 2009Publication date: October 22, 2009Inventor: Mark J.

Publication number: 20080154351Abstract: Various stent structures are provided with improved axial and torsional flexibility. One type of stent structure includes multiple segmented stent structures connected to each other by biodegradable interconnectors. A delivery system adapted to delivery the multiple segmented stents is also described. Another type of stent structure includes biodegradable connectors that are incorporated into a framework of non-biodegradable interconnecting members that form the support structure of the stent. The biodegradable connectors in both stent structures degrade or are absorbed after the stent is deployed. Stabilizing elements may be provided to the stent structures to supplement the stiffness of the stent with stability during loading and deployment.Type: ApplicationFiled: September 6, 2007Publication date: June 26, 2008Inventors: Alan R. Leewood, David D. Grewe, Mark J. Hiatt, Anthony O. Ragheb, William D. Voorhees, Blayne A. Roeder, James D. Purdy
