US Patent:

20140053415, Feb 27, 2014
Filed:

Aug 23, 2013
Appl. No.:

13/974183
Inventors:

Derek R. Eller - Orient OH, US
Tyson L. Rugenstein - Camby IN, US
Christopher B. Crabtree - Bloomington IN, US
Dennis A. Maddox - Solsberry IN, US
Jeffry S. Melsheimer - Springville IN, US
Preston R. Pameijer - Bloomfield IN, US
Assignee:

COOK MEDICAL TECHNOLOGIES LLC - Bloomington IN
International Classification:

B26B 27/00
US Classification:

30278
Abstract:

A cutting tool is provided for cutting the end of a catheter to provide custom length catheters. The cutting tool has a cutting member that moves within the cutting passageway in the housing. The catheter is positioned within a catheter passageway in the housing. The cutting passageway transacts the catheter passageway so that a blade on the cutting member crosses the catheter passageway and cuts through the width of the catheter to form a cut end on the catheter.

Rotational Drive System For A Biopsy Member

US Patent:

20140026693, Jan 30, 2014
Filed:

Jul 23, 2013
Appl. No.:

13/948560
Inventors:

Derek R. Eller - Orient OH, US
International Classification:

F16H 19/04
A61B 10/02
US Classification:

74 30
Abstract:

A drive system is provided for rotating a biopsy member. The drive system includes a pinion connected to the biopsy member and a rack that drives the pinion during a drive stroke. During the return stroke, the rack rotates away from the pinion so that the rack is not engaged with the pinion during the return stroke. Thus, the pinion is only driven during the drive stroke but not during the return stroke. As a result, the biopsy member rotates in a single direction as a trigger is repeatedly pressed and released.

US Patent:

20190069986, Mar 7, 2019
Filed:

Aug 27, 2018
Appl. No.:

16/112885
Inventors:

- Bloomington NC, US
Derek ELLER - Orient OH, US
Jarin A. KRATZBERG - Lafayette IN, US
Blayne A. ROEDER - Lafayette IN, US
International Classification:

A61F 2/07
A61F 2/90
A61F 2/848
Abstract:

A prosthesis for placement within an aortic root, includes a graft having a proximal end, distal end, and lumen disposed therethrough and a stent assembly disposed at that proximal end of the graft, the stent assembly comprising a first stent unit comprising a first proximal section having a first bend interconnected by a first curved strut and a second curved strut and a second bend interconnected by a third curved strut and a fourth curved strut, the first bend of the first proximal section and second bend of the first proximal section facing each other and circumferentially spaced apart; and a first distal section connected to the first proximal section.

Selective Fluid Barrier Valve Device And Method Of Treatment

US Patent:

20180243085, Aug 30, 2018
Filed:

Apr 24, 2018
Appl. No.:

15/960899
Inventors:

- Bloomington IN, US
Derek Eller - Orient OH, US
International Classification:

A61F 2/24
A61M 39/28
A61M 39/22
F16K 7/06
A61M 39/06
Abstract:

Selective fluid barrier valve devices and methods of treatment are described herein. An embodiment of a selective fluid barrier valve device comprises a housing, an actuator, a sleeve, a wire member, and a connector. The sleeve defines a passageway that extends through the sleeve. The actuator is moveable between a first position and a second position. When the actuator is in the first position, the sleeve is in a first configuration such that fluid can pass through the passageway defined by the sleeve. When the actuator is in a second position, the sleeve is in a second configuration such that fluid is prevented from passing through the passageway defined by the sleeve.
