Abstract: Systems for less invasive medical procedures comprise a filter device mounted on an integrated guiding structure and an aspiration catheter. These components can be used together or separately, and the system can be used with other medical devices that are designed for less invasive procedures, such as procedures in a patient's vasculature. The filter device can involve improved torque coupling with a torque coupler associated with a resilient member that correspondingly also provides increased flexibility relative to an overtube that forms a tube for the remaining portions of the device. An actuation tool for the filter device used a systematic loading procedure for proper loading of the corewire and overtube into the actuation tool. A fiber cartridge comprises fibers loaded as a bundle into the cartridge for delivery with the ends of the fibers respectively bonded to radiopaque markers that can be visualized to come together when the filter is properly deployed.

Abstract: A forceps includes two arms, two nipping tips and two sleeves. Each sleeve defines a through hole therein and forms a plurality of threads on an inner surface thereof. Each arm forms a first mounting pole towards a corresponding nipping tip. Each nipping tip forms a second mounting pole towards a corresponding arm. The first and second mounting poles each have a thread section and a smooth section. The first mounting pole and the second mounting pole abut against each other and are received in the through hole of a corresponding sleeve. The thread section of the first mounting pole and the thread section of the second mounting pole cooperatively form a thread pole. The smooth section of the first mounting pole and the smooth section of the second mounting pole cooperatively form a smooth pole. The sleeve is threaded with the thread pole.

Relative motion between the second sheath and the grasping component allows the proximal end of the deployable arm to be deployed for grasping a distal portion of an implantable medical device, and relative motion between the second sheath and the first sheath allows the expandable portion of the first sheath to radially expand to receive a proximal portion of the implantable medical device.

Abstract: A drain tube stripper containing two handles pivotally joined at one end. The second end of each handle contains a roller. The rollers meet when the handles are pressed together. The handles are of unequal length. A drain tube, e.g., surgical drain, can be stripped of fluid and material buildup by placing the open rollers over the tube and pressing the handles together. The rollers thereby pinch the drain tube and the rollers allow the device to be moved along the drain tube pushing fluid and material ahead of the rollers. The drain tube stripper allows the tube to enter between the rollers from the side and exit from the side of the opposing handle. The tube drain stripper may also contain a guide component to minimize entanglement of the drain and the device is rolled along the drain tubing.
