Patent number: 10258454Abstract: A removable vena cava filter configured for reduced trauma and enhanced visualization of anchoring hook placement relative to the vessel wall is disclosed. The filter includes a plurality of struts, each having an anchoring hook and a stop member proximate the anchoring hook. The stop members are configured to engage the vessel wall to prevent excessive penetration of the anchoring hooks into the vessel wall and to aid in the identification of anchoring hook placement relative to the vessel wall.Type: GrantFiled: January 26, 2017Date of Patent: April 16, 2019Assignee: COOK MEDICAL TECHNOLOGIES LLCInventors: Arne Molgaard-Nielsen, Jacob Lund Clausen, Per Hendriksen

Patent number: 9687242Abstract: An occlusion device (30) includes at least one self-expanding frame (42, 44) and graft material (46). Occlusion occurs by constricting the graft material (46) at a substantially central point or at an end of the device. The constriction is sized such that a guide wire (34) is able to pass therethrough. A valve mechanism (50) includes a screen (52) made from a resilient material and which includes a closable opening (54). The valve mechanism (50) allows a guide wire to pass through the occlusion device (30) while an effective physical barrier is maintained after removal of the guide wire (34).Type: GrantFiled: April 3, 2009Date of Patent: June 27, 2017Assignee: COOK MEDICAL TECHNOLOGIES LLCInventors: Per Hendriksen, Jacob Lund Clausen, Frank K.

Patent number: 9427244Abstract: A medical device for collecting objects from a body lumen comprises a catheter, a basket having a closed first end and an open second end, and an actuator connected to the closed first end of the basket, the catheter and basket moveable relative to one another between a first configuration and a second configuration to draw objects from a body lumen into the basket. In the first configuration the closed first end of the basket is inside the catheter and the open second end is everted over at least a part of the closed first end. The apparatus may be actuated to pull the closed first end of the basket further into the catheter and invert the second end of the basket, the second end scraping the sides of the lumen as it inverts, surrounding an object in the lumen, and drawing the object into the basket.Type: GrantFiled: December 7, 2012Date of Patent: August 30, 2016Assignee: COOK MEDICAL TECHNOLOGIES LLCInventors: Jacob Lund-Clausen, Palle Munk Hansen, Petar Mihaljevic, Kerstin Svensson

Patent number: 8845710Abstract: An introducer for use in the implantation and retrieval of a device in a patient includes a catheter (43) within which a stylet (14) is slidably carried, the stylet (14) being biased to a retracted position by a spring (35) and deployable by depression of an actuator (50). A locking device (40) locks the stylet (14) relative to the catheter (43) such that the locking device (40) must be disengaged prior to operation of the actuator (50). In the preferred embodiment, both the locking device (40) and the actuator (50) must be actuated by movement thereof in a direction substantially perpendicular to the direction of motion of the stylet (14). In an alternative embodiment, it is the catheter (43) which moves relative to the stylet (14).Type: GrantFiled: February 21, 2008Date of Patent: September 30, 2014Assignee: Cook Medical Technologies LLCInventors: Per Hendriksen, Jacob Lund Clausen

Publication number: 20130338699Abstract: A vascular occluder includes a frame (10) having a generally cylindrical body portion (12), first and second end conical portions (14, 16) and first and second extremities (18, 20). Located within the fame (10) is a fibrous barrier (28) which provides rapid occlusion. The extremities (18, 20) are coupled by a coil spring (22) which acts to pull the extremities (18, 22) towards one another and thereby to cause longitudinal contraction an consequential radial expansion of the frame (10). The coil spring (22) ensures rapid and reliable deployment of the occluder in a patient's vessel. The occluder also can be compressed to a narrow diameter for deployment by means of narrow diameter sheaths.Type: ApplicationFiled: March 14, 2013Publication date: December 19, 2013Applicant: Cook Medical Technologies LLCInventors: Jacob Lund Clausen, Per Hendriksen, Jeppe Boeckhaus Johnsen, Nicholas Gulmann Lundsteen, Bent Oehlenschlaeger

Publication number: 20110301630Abstract: An occlusion device having a frame including a plurality of radially expandable struts formed from a plurality of cuts through a tubular wall of a tube. The frame includes a first collar at a proximal end and a second collar disposed in between the proximal and distal ends of the device. A bulbous portion extends between the first and second collars. The bulbous portion includes first and second conical portions joined at their respective bases. A third conical portion extends from the second collar to the distal end of the device. The second conical portion adjacent the second collar and the third conical portion are each defined by a set of cuts forming substantially the same pattern. The first conical portion is defined by a set of cuts forming a pattern that is different from that of the second and third conical portions. The bulbous portion and the third conical portion are configured to expand to approximately the same outer diameter.Type: ApplicationFiled: June 2, 2010Publication date: December 8, 2011Applicant: COOK INCORPORATEDInventors: Per Hendriksen, Jacob Lund Clausen
