Filed:

Oct 30, 2003
Appl. No.:

10/697486
Inventors:

George Gullickson - Bloomington MN, US
Mark T. Stewart - Lino Lakes MN, US
Joseph E. Cardinal - Brooklyn Park MN, US
Harry A. Puryear - Shoreview MN, US

Assignee:

Medtronic, Inc. - Minneapolis MN
International Classification:

A61M 25/092
US Classification:

606 41, 606 1, 604 9504
Abstract:

A deflection mechanism for selectively inducing a bend in a catheter body includes an elongated deflection wire extending within a deflection lumen of the catheter body and into a handle. A guide track is formed within the handle and a thumb wheel is mounted proximal to the elongated guide track within the handle and supports a pinion gear; the thumb wheel and the pinion gear are adapted to be rotated about a common thumb wheel axis, which extends substantially perpendicular to the longitudinal axis. A rack arm extends obliquely to the longitudinal axis of the handle and includes runners received by the guide track, an attachment point coupling the deflection wire to the rack arm and a linear rack engaging the pinion gear. Rotation of the thumb wheel in a first direction draws the deflection wire proximally through the deflection lumen.

International Classification:

A61B 17/122
US Classification:

606142000, 606157000
Abstract:

Some embodiments of the invention provide a system for occluding a left atrial appendage of a patient. Some embodiments of the system can include a ring occluder that can be positioned around the left atrial appendage and a ring applicator to position the ring occluder with respect to the left atrial appendage. One embodiment discloses a method of accessing endocardial surfaces of the heart through the atrial appendage. Additional embodiments of the invention provide a clip occluder that can be positioned around the left atrial appendage. A clip applicator can position the clip occluder with respect to the left atrial appendage.

International Classification:

A61B 17/12
A61B 17/122
US Classification:

606139, 606158
Abstract:

A novel occluder application and clip device for treatment of embolic stroke caused by atrial fibrillation uses multiple sutures in a non directional handle to affix the occlusion device to the applicator and manipulate the occluder from an open and receiving position to a closed and occluding position. The occluder is retained in place by a clamping means related to locks retainers, resilient material or otherwise. An actuator mechanism is used to manipulate the occluder to a locked or occluding position. The applicator with the occluder attached has a low profile and remote manipulations to allow the occluder to be delivered to the clamping location within a patient through a small incision or delivery port such as a trocar cannula or the like.
