Abstract: A device (e.g., an annulus-constricting device) with N anchors may be affixed to a cardiac valve annulus as follows. First, the device is delivered to the vicinity of the annulus via a catheter. Next, the position and layout of the device is adjusted via the catheter. Next, only those anchors which are properly positioned are driven into the annulus or tissue adjacent to the annulus. The remaining anchors remain unlaunched at this point. The unlaunched anchors are subsequently moved into a good position using either a manipulating tool or catheter-steering techniques, after which they are driven into the annulus or tissue adjacent to the annulus.

Abstract: A set of devices and associated methodology for percutaneously closing a puncture through the wall of an artery.

Abstract: A closure system for delivering a sealant to an arteriotomy. A distal section of the closure system can include overlapping inner and outer sleeves that can expand with expansion of the sealant. A proximal section of the closure system can include a handle portion and a sheath adapter extending from the handle portion. The handle portion can comprise one or more actuators that when depressed or engaged can assist in deployment of the sealant in the arteriotomy and can further include tamping of the sealant and/or retraction of an expandable member. The sheath adapter can removably engage a side port or an irrigation line of a standard procedural sheath.

An elastic supporting member (30) is provided at a periphery of the window (20); an imaging member (40) is provided on the elastic supporting member (30); and at least part of the imaging member (40) is movably connected to the elastic supporting member (30). Since the imaging member (40) and the elastic supporting member (30) are located at the periphery of the window (20), the imaging member (40) and the elastic supporting member (30) enable the periphery of the window (20) to simultaneously have a good imaging performance and a good supporting performance.

Abstract: A surgical clamp for aligning the margins of incised or wounded tissue has jaws with parallel clamping faces, and a handle for manipulating the clamp to align the margins of the tissue. The jaws are in a normally closed position, however they can be opened by compressing the handle to open the jaws. Prongs project from the inferior surface of the jaws. The clamp is positioned in a desired position over the margins of a wound to be closed, the prongs engage the margins of the wound to be aligned, and the jaws are closed by releasing compressive force on the handle. As the jaws close the prongs help move the tissue into alignment. Suture guide slots through the jaws assist in the placement of precisely placed sutures across the incision. The disclosed surgical clamp is particularly suited for selectively closing and reopening surgical incisions, such as a sclerotomy incision in the eye. Methods are disclosed for using the clamp during intraocular and other surgical or minimally invasive procedures.
