Patent number: 10231815Abstract: The disclosure provides for a spiral filter and delivery apparatus where the filter comprises a support supporting a body and defining a frame. The frame comprises a proximal end extending to a distal end. A filtering member may be attached to the proximal end and extend distally to the distal end. The filtering member and the frame may move between a delivery state and a deployed state. In the deployed state, the frame extends helically within the circumference of the body vessel and has a filtering lumen formed therethrough. The filtering member may be disposed within the filtering lumen in a spiral for filtering within the intended body vessel.Type: GrantFiled: January 11, 2016Date of Patent: March 19, 2019Assignee: COOK MEDICAL TECHNOLOGIES LLCInventors: Jeppe Dufresne Johnsen, Jens Kold, Rasmus Boje Vendelbo Juliussen

Patent number: 10123864Abstract: A vena cava filter includes a plurality of filter legs with distal ends. Each distal end is a tip which curves radially outwardly and ends in a spherical or part spherical enlarged head element. A biodegradable barb is attached to the enlarged head element and is made of a biodegrade material, such that after degradation the enlarged head element also is left embedded in the vessel wall. The degradation of the barb will prevent further penetration of the distal end of the filter legs into the vessel wall and avoid any risk of piercing through the vessel wall. The enlarged head element also ensures that the distal ends of the filter legs remain firmly attached into the vessel wall in order to ensure correct long term placement of the filter in the vessel.Type: GrantFiled: June 30, 2015Date of Patent: November 13, 2018Assignee: COOK MEDICAL TECHNOLOGIES LLCInventor: Jeppe Dufresne Johnsen

Patent number: 10117736Abstract: The disclosure provides a filter apparatus and method of filtering in a body vessel. The filter apparatus comprises a filter unit and an expandable introducer designed to deliver the filter unit to the target filtering site. The filter unit attaches to the expandable introducer via a plurality of anchors on the filter unit. The expandable introducer delivers and presses the anchors to the vessel wall during implantation. After implantation, the filter unit exerts minimal or about zero radial force against the vessel wall.Type: GrantFiled: August 5, 2015Date of Patent: November 6, 2018Assignee: COOK MEDICAL TECHNOLOGIES LLCInventors: Jeppe Dufresne Johnsen, Bent Oehlenschlaeger, Erik Rasmussen, Palle Hansen

Patent number: 9962253Abstract: The present disclosure relates to a loop vascular device and a method to retrieve said device from the body vessel of a patient. The loop vascular device comprises a loop having a first portion extending distally to a splitting portion, and a second portion also extending distally to the splitting portion, defining a close state of the loop. The splitting portion may be split such that the first portion is separated from the second portion when in the body vessel, defining an open state of the loop. In the open state, the loop may be easily retrieved through ingrowth in the body vessel, reducing or eliminating possible negative effects to the vessel wall.Type: GrantFiled: September 24, 2015Date of Patent: May 8, 2018Assignee: COOK MEDICAL TECHNOLOGIES LLCInventor: Jeppe Dufresne Johnsen

Patent number: 9867689Abstract: The present disclosure relates to a loop vascular device and a method to retrieve said device from the body vessel of a patient. The loop vascular device comprises a loop having a first portion extending distally to a first bar, and a second portion extending distally to a second bar. In a close state of the loop, the first and second bars are maintained or housed inside a first cannula. The first cannula may be in contact with a second cannula. Upon desiring to open the loop, the physician may separate the first cannula from the second cannula, allowing the bars to exit the first cannula and disconnect from each other, defining the open state of the loop. In the open state, the loop may be easily retrieved through any ingrowth in the body vessel.Type: GrantFiled: September 24, 2015Date of Patent: January 16, 2018Assignee: COOK MEDICAL TECHNOLOGIES LLCInventor: Jeppe Dufresne Johnsen
