摘要： Catheters and uses of same are described. The catheter may be an aspiration or distal access catheter used to treat stroke or other neurovascular conditions and may include a proximal segment and a distal segment with fixed shapes and outer diameters, and a distensible segment that is located proximal to the distal segment and adjacent to the catheter distal end and that is configured to undergo a conformation change when the catheter open distal end is lodged against the wall of a human blood vessel and a surgeon is attempting to move the catheter distally through the human blood vessel. The catheter may include a wall that is comprised of an inner tube surrounding the catheter's hollow interior, a coil surrounding the inner tube, a braid surrounding the coil and/or an outer tube surrounding the braid. The pitch of the coil may be greater in the distensible segment as compared to the proximal segment and the outer tube may not be attached to the inner tube for at least a portion of the distensible segment, which features allow for the distensible segment to undergo the conformational change. The distal segment may include a metallic marker band, providing rigidity to the distal segment.

摘要： Systems and methods for monitoring a bypass device for protecting an intestinal anastomosis are provided. The system includes a pump, one or more fluid inlet lines fluidicly coupled to the pump and to a negative pressure chamber of the bypass device, and one or more sensors configured to measure data indicative of pressure within the negative pressure chamber. A controller operatively coupled to the pump and the one or more sensors may be programmed to actuate the pump to generate a vacuum within the negative pressure chamber to thereby pull intestinal tissue towards the bypass device to anchor the bypass device at a target location upstream of the intestinal anastomosis. The controller further may compare the pressure within the negative pressure chamber with a predetermined pressure range and, if the pressure falls outside the predetermined pressure range, adjust the pump to maintain the vacuum within the predetermined pressure range.

摘要： Methods for removing clot material by directional aspiration may include removing clot material from a side vessel while the suction catheter remains in the main vessel. These methods may include a steerable distal end region. In some cases the apparatuses and methods may include the use of a guide catheter and/or a guidewire in orienting the suction catheter to laterally capture clot material from a side vessel without having to enter the side vessel. Any of these methods may include optionally sensing and confirming clot material (e.g., electrically sensing).

摘要： A vitrector for removing material from an eye includes a hand piece, a shaft coupled at a first end to a first end of the hand piece, the shaft having a sharp second end opposite the first end of the shaft, and a cutting device positioned within the shaft and configured for removing the material from the eye. The sharp second end of the shaft is configured for piercing a pars plana of the eye and a sclera of the eye. A method for removing material from an eye includes forming a single opening through a pars plana of the eye and a sclera of the eye using a sharp point of a shaft of a vitrector, cutting the material using a cutting device incorporated within the shaft, and removing the material from the eye using the vitrector.

摘要： An aspiration thrombectomy system includes a thrombectomy catheter assembly that maintains pulsatile energy of cyclic aspiration while the catheter is occluded. A system configuration includes a catheter, vacuum and vent fluid sources respectively connected to vacuum and vent valves, a vent catheter valve connecting a catheter lumen to the vent fluid source, a manifold connected to the catheter and vacuum and vent valves, a pressure sensor upstream of the vacuum valve, and a controller configured to operate the vacuum, vent, and vent catheter valves, receive sensor pressure data, control the vent catheter valve dependent upon the data. Determination can be upon decrease of pressure waveform amplitude. An operable lumen of the system includes a volume of the catheter lumen and an interior of the manifold up to an input of the vacuum valve input and an output of the vent valve.

摘要： The present invention relates to a handheld gynecological apparatus (10; 110; 210) for cervix handling, comprising a body member (12; 112; 212) having a proximal end (18) and a distal end (20), a rod member (26) having a proximal end (32) and a distal end (34), the rod member (26) defining a lumen (30) and being configured to be fluidly connected to the distal end (20) of the body member (12), a suction head having an engaging portion configured to engage at least a portion of a cervix of a patient, the suction head being fluidly connected to the distal end (34) of the rod member (26) and having a cross-section that is larger than a cross-section of the rod member (26); and a vacuum generating mechanism configured to generate a vacuum within at least a portion of the gynecological apparatus (10; 110; 210). A first member and at least one second member of the gynecological apparatus (10; 110; 210) are connectable to each other by a quick release coupling (60; 160) configured for manually coupling and uncoupling the first member and the second member to each other. The first member is the rod member (26) and the second member is one of the body member (12) and the suction head. The present invention also relates to a handle and a rod member for a handheld gynecological apparatus.
