Patent number: 9592372Abstract: A hemostasis mechanism includes a deformable seal, and a plunger guided for translation within a housing to displace a fluid to a clearance extending between the deformable seal and the housing. The displaced fluid increases fluid pressure in the clearance to deform the deformable seal into sealing contact with a medical device. An actuator for the plunger includes a linkage having arms rotatable about first and second axes, and configured such that their rotation is converted into translation of the plunger. The linkage is adjustable from a retracted configuration to an advanced, cammed-over configuration.Type: GrantFiled: July 10, 2014Date of Patent: March 14, 2017Assignee: Cook Medical Technologies LLCInventor: Randy Joe Myers

Patent number: 9216277Abstract: A hemostasis mechanism includes a housing, and a pressure responsive seal positioned within the housing and having an outer seal surface exposed to a fluid pressure of a port formed in the housing. A pressurization device is in fluid communication with the port, and includes a detent having a release state, and an engaged state holding a plunger of the pressurization device at an advanced position to maintain an increased fluid pressure supplied to the pressure responsive seal to maintain sealing engagement about a transluminal device. Related methodology is also disclosed.Type: GrantFiled: February 18, 2013Date of Patent: December 22, 2015Assignee: Cook Medical Technologies, LLCInventor: Randy Joe Myers

Publication number: 20140027305Abstract: A method of electropolishing a medical implant is provided. During the electropolishing, an anodotic film forms around surfaces of the implant. Two or more ultrasonic transducers are oriented around the implant and are activated to disrupt the anodotic film. The ultrasonic transducers are activated only during a portion of the electropolishing process to allow the anodotic film to at least partially reform.Type: ApplicationFiled: July 23, 2013Publication date: January 30, 2014Applicant: COOK MEDICAL TECHNOLOGIES LLCInventor: Randy Joe Myers

Publication number: 20110152715Abstract: A surgical cutting device comprises a cannula attached to an actuation mechanism that moves the cannula from a cocked position to a cutting position, a stylet including a distal portion having a sharp distal end, a sample collection region, a vacuum port, and a lumen extending from the vacuum port to the sample collection region such that the sample collection region is in fluid communication with the first vacuum port. When the cannula is in the cocked position, the sample collection region of the stylet is disposed distal of the cannula. The device also includes a fixed volume vacuum source. When cannula is in the cocked position, the vacuum port is not in fluid communication with the fixed volume vacuum source, and when said cannula is in the cutting position, the vacuum port is in fluid communication with the fixed volume vacuum source.Type: ApplicationFiled: December 22, 2009Publication date: June 23, 2011Applicant: Cook IncorporatedInventors: Dennis J. Delap, Cleve S. Koehler, Robert S. Childress, Randy Joe Myers

Patent number: 7879387Abstract: A process for electrostatically coating a stent on a catheter. A conductor which is permanently affixed to the catheter contacts a stent mounted on the catheter. Conductive ink applied to the catheter may be used as the conductor. An electrical charge is applied to the conductor. The stent is then coated using an electrostatic coating process.Type: GrantFiled: January 14, 2008Date of Patent: February 1, 2011Assignee: Cook IncorporatedInventor: Randy Joe Myers

Patent number: 7875284Abstract: This disclosure relates to endolumenal medical devices coated with a taxane therapeutic agent in one or more solid form(s) having varying dissolution rates. Particularly preferred coatings comprise amorphous paclitaxel, dihydrate paclitaxel, or combinations thereof that provide durable coatings that release paclitaxel over a desired period of time, which can be on the order of hours, days or weeks. Preferred embodiments relate to medical device coatings of paclitaxel, or paclitaxel analogs or derivatives, having one or more polymorph solid forms that provide a prolonged release of paclitaxel within a body vessel without requiring a polymer carrier or barrier layer to achieve the desired rate of paclitaxel elution.Type: GrantFiled: June 27, 2007Date of Patent: January 25, 2011Assignees: Cook Incorporated, Med Institute, Inc.Inventors: Priscilla Reyes, William F. Moore, Randy Joe Myers, Patrick H. Ruane, Melinda S. Morrell

Patent number: 7799201Abstract: An electropolishing apparatus and method are provided for polishing stents and other medical implants. The apparatus includes a motor that rotates a roller. The roller continuously rotates the medical implant to be electropolished. One of the advantages of the apparatus and method is that marks generated around the electrical contact between the anode and the medical implant are minimized. In addition, the medical implant is polished more evenly than conventional electropolishing systems.Type: GrantFiled: March 26, 2010Date of Patent: September 21, 2010Assignee: Cook IncorporatedInventors: Darin G. Schaeffer, Randy Joe Myers

Publication number: 20100049167Abstract: An introducer sheath has an inner liner having a first length comprising a major diameter, a second length comprising a minor diameter, and a tapered third length axially disposed between the first and second lengths. A coil is positioned over the inner liner and spans at least a portion of each of the first, second, and third lengths. An outer jacket is positioned longitudinally around the reinforcing member and the inner liner, and is bonded to the outer surface of the inner liner. The outer jacket has a first length comprising a major diameter, a second length comprising a minor diameter, and a tapered third length axially disposed between the first and second lengths. The outer diameter first, second, and third lengths substantially correspond to and are disposed radially outwardly of the respective inner liner first, second, and third lengths.Type: ApplicationFiled: August 20, 2008Publication date: February 25, 2010Applicant: Cook IncorporatedInventor: Randy Joe Myers
