Navigation and tissue capture systems and methods for navigation to and/or capture of selected tissue using the innate electrical activity of the selected tissue and/or other tissue are described. In the context of left atrial appendage closure, the systems and methods can be used to navigate to the left atrial appendage and capture/control the appendage while a closure instrument (suture, clip, ring) is placed over the appendage and tightened down or a closure method (ablation, cryogenic procedures, stapling, etc.) is performed to close the left atrial appendage. The use of innate electrical activity for navigating devices may be used in connection with other tissues and/or areas of the body.

Enhanced signal navigation and capture systems and methods

Navigation and tissue capture systems and methods

Systems and methods capture and/or occlusion of selected body tissue using various tissue characteristics and/or techniques are described. In the context of left atrial appendage closure, the systems and methods can be used to capture the left atrial appendage while a closure instrument (suture, clip, ring, etc.) is placed over the appendage and tightened down or a closure method (ablation, cryogenic procedures, stapling, etc.) is performed to close the left atrial appendage.

Tissue capture and occlusion systems and methods

A suture lock including a first bore, a first restriction member extending into the first bore for restricting the movement of a suture element within the first bore, an optional second bore, and a second restriction member extending into the second bore for restricting the movement of a suture element. The suture lock may be provided in a system including a suture element. Methods of using the suture locks are also described.

Suture locks and suture lock systems

Devices and methods for ligating structures where the loop of the ligation element can be temporarily pre-tightened without locking the loop. This pre-tightening without locking allows the loop of the ligation element to be loosened and repositioned, if necessary, before locking the loop around the anatomical structure.
