Abstract: Among other things, there is disclosed structure and methods for maintaining access to a location in the body while reducing or eliminating the potential for pulling an access device (e.g. a catheter) back through an opening. An introducer sheath includes a distal indented portion and a balloon, so that once placed in a desired location through tissue, the balloon can be inflated to anchor the sheath against retraction. In particular embodiments, structure and methods for accessing the pericardial cavity via the right atrial appendage are shown.

Abstract: Among other things, there are shown embodiments of locking mechanisms for holding sutures in tension. Such devices may be used with implants that use or require sutures, and are easily locked remotely. In particular embodiments, a lock includes a housing member, a pin member at least partially within the housing member, and a spring biasing the pin member into the housing member. The pin member includes a gripping portion, and has a retracted condition and a locked condition. When retracted, a suture can move through the housing member and around the gripping portion of the pin member. When locked, the gripping portion of the pin member engages the suture and presses it against the interior of the housing member.

Abstract: Among other things, there are disclosed embodiments of belts or bands that can be used in treatments for tricuspid valve regurgitation. In some embodiments, such belts may be heat-set in a particular configuration to effectively decrease tricuspid annulus when deployed around the atrioventricular groove. Embodiments include one or more tensioning sutures for applying cinching or tightening to belts when deployed, and structure for effectively distributing force during such tightening.
