Abstract: This material comprises an annuloplasty member able to be introduced using a catheter through minimally invasive vascular access, then to be delivered by said catheter and fixed to the valve annulus. According to the invention, it includes at least one catheter comprising at least one guide member able to be deployed from said catheter such that it extends along one portion of the valve annulus of the valve, in the immediate proximity of said valve annulus, and an implant having a helical shape engaged on said guide member, connected, with separation possibility, to actuation means making it possible to cause this implant to move forward while driving it in rotation around its axis; the implant can thus be deployed from the catheter while being simultaneously moved forward and driven in rotation along its axis.
Abstract: The present disclosure relates to an arrangement, a loop-shaped support, a prosthetic heart valve and a method of repairing or replacing a native heart valve.

Abstract: A percutaneous heart valve prosthesis (1) has a valve body (2) with a passage (9) extending between the first and second ends (7, 8) of the valve body (2). The valve body (2) is collapsible about a longitudinal axis (10) of the passage (9) for delivery of the valve body (2) via a catheter (18). One or more flexible valve leaflets (3, 4) are secured to the valve body (2) and extend across the passage (9) for blocking bloodflow in one direction through the passage (9). An anchor device (5), which is also collapsible for delivery via catheter (18), is secured to the valve body (2) by way of an anchor line (6). A failed or failing mitral heart valve (101) is treated by percutaneously locating the valve body (2) in the mitral valve orifice (102) with the anchor device (5) located in the right atrium (107) and engaging the inter-atrial septum (103), such that the taught anchor line (6) acts to secure the valve body (2) within the mitral valve orifice (102).
Abstract: The present embodiments provide prosthesis deployment systems. In one embodiment, a sleeve has proximal and distal regions and a lumen extending therebetween, and further comprising a first exit aperture, a first entrance aperture, and a second exit aperture. A trigger wire is disposed at least partially within the lumen of the sleeve. A prosthesis has a delivery state and an expanded state, and further has first and second regions. In the delivery state, the trigger wire extends out of the lumen through the first exit aperture of the sleeve, restrains the first region of the prosthesis, reenters the lumen through the first entrance aperture of the sleeve, extends out of the lumen through the second exit aperture of the sleeve, and restrains the second region of the prosthesis.
Abstract: A force-directional nasal surgery dilatation device for use in a medical procedure such as sinuplasty, correction of deviated septum, and expansion of sinus cavities and nasal passages. An inflatable balloon is affixed to the distal end of a shaft for supporting and guiding the balloon into position for a nasal surgery procedure involving a patient. The shaft includes an inflation passageway associated for introducing an inflation medium into the balloon. The device further includes a force distribution member affixed to the inflatable balloon that provides a relatively rigid surface for applying distributed force against a tissue in the patient's nasal cavity upon inflation of the balloon. The force distribution member can include a pair of generally planar articulated adjacent surfaces attached along a hinge line between the surfaces.
Abstract: A hydraulically-driven Intra-Ocular Lens (IOL) insertion tool includes a body, a chamber within the body, a first fluid port providing fluid communication into the chamber, a piston positioned within the chamber and arranged to move within the chamber in response to the introduction or removal of fluid from the chamber, and an elongated member. The elongated member includes a distal end comprising an intra-ocular lens interface and a proximal end connected to the piston such that movement of the piston within the chamber causes corresponding movement of the elongated member.

Abstract: Systems and method are described for counterbalancing the force required to deform a flexure joint. The system includes an elastically deformable flexure joint, a control joint, and an energy balance system. The control joint is mechanically linked to the flexure joint such that movement of the control joint causes a corresponding deformation of the flexure joint. The energy balance system provides a spring force to aid movement of the control joint and to overcome an elastic force required to deform the flexure joint.
Abstract: A compression ring to grip and compress body structure such as diverticulum, hemorrhoids, and tissue adjacent a hole. A resilient ring-shaped body defines a compression channel, and one or more axially rigid elongated spikes extend from the body into the channel.

Abstract: A securing device for securing a flexible line to another object. The clip has a working end and a clip end, the former for attachment to the other object and the latter for securing the line. The clip end has two loops and a locking clip. The two loops extend in opposite directions away from the locking clip, and are connected by a crossbar which is perpendicular to and against the locking clip. The locking clip is formed from two parallel shafts, closely spaced together. The line is secured by wrapping it at least twice around the loops, then up over the crossbar and down into the locking clip.
