Patent number: 11992645Abstract: According to one aspect of the disclosure, a delivery device may include a handle, a catheter sheath extending distally from the handle, and a hemostasis valve positioned within the handle. The hemostasis valve may be located proximal the catheter sheath and distal to a proximal end of the handle. The delivery device may also include a hemostasis bypass assembly coupled to the handle. The hemostasis bypass assembly may include a bypass tube coupled to an actuator. The actuator may be configured to be transitioned between a first condition in which a distal end of the bypass tube is positioned proximal to the hemostasis valve and the hemostasis valve is closed, and a second condition in which the distal end of the bypass tube traverses the hemostasis valve and the hemostasis valve is opened.Type: GrantFiled: February 10, 2022Date of Patent: May 28, 2024Assignee: St. Jude Medical, Cardiology Division, Inc.Inventors: Tracee Eidenschink, Mathias C.

Publication number: 20210145422Abstract: A medical device is provided in which one or both ends of the device encourage the formation of tissue across substantially the entire area of the respective end that is exposed to the blood flow for reducing the risk of a thrombotic embolism. The medical device includes a tubular structure having at least one expanded volume portion and a tapered transition portion. The tubular structure may be made through the braiding of a number of strands, and a first end feature may be used to secure the proximal strand ends. The proximal strand ends may be secured via the proximal end of the first end feature, such that the tapered transition portion is formed over the circumferential surface of the first end feature, and only a proximal end surface (or a portion of the proximal end surface) of the first end feature is exposed to the path of flowing blood.Type: ApplicationFiled: January 28, 2021Publication date: May 20, 2021Inventor: Mathias C.

Publication number: 20200367905Abstract: Embodiments of the present invention provide devices and methods for treating various target sites, such as vascular abnormalities. For example, a medical device according to one embodiment includes at least one layer of a fabric of braided strands having proximal and distal ends and a central axis extending therebetween. The medical device has an expanded configuration a generally frustroconical shaped portion at each end. The medical device is configured to be constrained to a reduced configuration for delivery through a diagnostic catheter and to at least partially return, when unconstrained, towards the expanded configuration.Type: ApplicationFiled: August 14, 2020Publication date: November 26, 2020Inventors: Sarah Ellen Drilling, John C Oslund, Mathias C Glimsdale, Xiaoping Gu

Patent number: 10201336Abstract: A device and method for delivering a vascular device to a target site is provided that allows an orientation of the vascular device at the target site to be adjusted by a user. In general, the delivery device includes an outer tubular member, an intermediate tubular member within the outer tubular member, and an inner member that can move axially within the intermediate tubular member. Each of the members defines a proximal end and a distal end. The intermediate and outer tubular members are fixed at their respective proximal ends, but are not fixed at their distal ends. Thus, a torque applied to the proximal end of the intermediate tubular member is at least partially transmitted to the distal end of the intermediate tubular member, allowing the user to rotate an attached vascular device by rotating the proximal end of the intermediate tubular member.Type: GrantFiled: March 25, 2011Date of Patent: February 12, 2019Assignee: St. Jude Medical, Cardiology Division, Inc.Inventors: Ryan Douglas Kariniemi, Mathias C.

Publication number: 20140371844Abstract: A prosthetic heart valve includes a collapsible and expandable stent, a collapsible and expandable valve assembly disposed within the stent, and one or more features coupled to the stent for at least partially anchoring the prosthetic heart valve within a native valve annulus of a patient. The anchoring features may include a body transitionable from an unfurled condition to a furled condition, the furled condition forming a flange for at least partially anchoring the heart valve, and/or a plurality of hooks transitionable from a deformed condition to a relaxed condition for at least partially anchoring the heart valve. A delivery device for the prosthetic heart valve may include a handle and a catheter member extending from the handle and having a first portion, a second portion, and a compartment for receiving the valve. The delivery device may provide for staged deployment of the valve.Type: ApplicationFiled: June 17, 2014Publication date: December 18, 2014Inventors: Theodore Paul Dale, Mathias C.

Patent number: 8821529Abstract: A device for occluding a septal defect is provided. In general, the occluding device has a contracted state that allows the occluding device to be received within a delivery device for deployment to the site of the defect and an expanded state that is achieved when the occluding device is deployed from the delivery device. The occluding device has a proximal portion, which may be substantially circular, a distal portion, which may be substantially ovaloid, and a connecting portion extending between the two. The distal portion may define first and second outer parts at opposite ends of the major axis, which may be bent or curved. The configuration of the proximal and distal portions allow the occluding device to securely engage the septal wall and be kept in position at the septal defect without causing substantial interference with the functioning of adjacent heart structures.Type: GrantFiled: March 25, 2011Date of Patent: September 2, 2014Assignee: AGA Medical CorporationInventors: Ryan Douglas Kariniemi, Mathias C.
