A myringotomy device includes a housing; an elongated tube extending from the housing; and a retractable cutting tool extendable through the elongated tube, the cutting tool comprising a blade. The cutting tool is configured such that when advanced, the blade of the cutting tool extends beyond a distal end of the elongated tube. The cutting tool is also configured such that when retracted, the blade is retracted into the elongated tube and a fluid conduit is created from the distal end of the elongated tube to the housing.

The present invention relates to a cutting device comprising a manual gripping element (100) and a cutting assembly (200) that is positioned on one end of the gripping element (100) and comprises a punch (210) split into at least two cutting tips (220, 230), at least one of these tips (220, 230) being hinged on the gripping element (100) in order to be movable between a rest and cutting position in which the tips (220, 230) are adjacent and a working and injection position in which the tips (220, 230) are spaced apart, and urging means (250) designed to move each movable tip (220, 230) into the working position when these urging means (250) press against the skin.

Disclosed herein is a delivery system for percutaneous heart valve repair, the delivery system including a steerable sheath configured to provide percutaneous access into a heart and to deliver an implant. The system may also have a steering mechanism configured to manipulate and orient the implant, a ball joint mechanism configured to connect the steerable sheath to the steering mechanism, a main knob assembly configured to advance and retract a multilumen shaft assembly, a stabilizing tool including a plurality of prongs configured to engage the implant within the heart to make an intimate contact with the heart tissue using a stabilizer and a tongue assembly, and a back assembly including: the actuation mechanism, a suture routing mechanism, a tip lock mechanism, and a back cover configured to protect all sutures being cut by mistake.

The present embodiments relate generally to systems and methods for measuring an analyte in a host. More particularly, the present embodiments provide sensor applicators and methods of use with activation that implant the sensor, withdraw the insertion needle, engage the transmitter with the housing, and disengage the applicator from the housing. Systems and methods according to present principles allow for such steps to occur without significant loss of spring force, and without deleterious effects such as seal slingshotting.

An implant delivery sleeve comprises a tubular wall having a proximal end with a proximal opening, a distal end with a distal opening, and an implant delivery channel extending between the proximal and distal ends of said tubular wall. A plurality of bands interconnect portions of the tubular wall for constricting the implant delivery channel adjacent the distal end of the tubular wall. As an implant is advanced toward the distal end of the tubular wall, the constriction squeezes and/or deforms the implant for facilitating insertion into an incision that is smaller than the normal size of the implant.

Articles and systems configured for treating GI motility disorders are generally provided. In some embodiments, an article comprising one or more electrodes (with both sensing and stimulating capabilities) may be configured to stimulate one or more tissues in the GI tract, electrically and/or chemically, to modulate peristalsis and/or allow neuromodulation. In some embodiments, a system comprises a controller that allows for close-loop operation of the article, e.g., such that the article may stimulate (e.g., via a feedback loop) the one or more organs in the GI tract upon receiving sensed parameters in the GI tract. In some embodiments, an implantation tool comprising a sensor may allow for submucosal or intramuscular implantation of an article. The implantation tool and the article may be useful for, for example, as a general platform for delivery of treating GI motility disorders and/or neuromodulation of the GI tract.

Various embodiments disclosed relate to a device for insertion into the urethra for dilation. The present disclosure includes methods and devices including a device for at least partial insertion into a prostate, the device including first and second elongated members each having at least one magnetizable or magnetic element. The first and second elongated members are magnetizable to repel each other to dilate a lumen therebetween.

An intraocular shunt can be placed into the eye in an ab externo approach. A clinician may determine an entry area below a corneal limbus of an eye and a target outflow region. Thereafter, the clinician can insert a hollow shaft into the eye at the entry area toward an anterior chamber of the eye, the shaft carrying an intraocular shunt therein. The clinician can position an inflow end of the shunt within the anterior chamber of the eye and, while maintaining the shunt inflow end in the anterior chamber, can remove the shaft from the eye to release the shunt. Finally, the clinician can repositioning an outflow end of the shunt within the target outflow region and verify placement of the outflow end of the shunt within the target outflow region.

Disclosed are apparatus and method for forming passage extending along a plane crossing an organ's volumetric region from an entry point to an opposing exit point at a surface of the organ, and for passing a tension member around the volumetric region by pulling the tension member from the exit point to the entry point through the passage. The apparatus can include a rigid outer tube with a tip for penetrating the organ and reach a penetration depth; an inner needle with elastic body configured to pass straightened through outer tube lumen and to partially protrude and voluntarily flex to a curved form greater than the diameter of the volumetric region; and a tension member passer with a pulling portion for engaging with portion of tension member and for pulling the tension member when withdrawn.

An implant injection device includes an injection needle, a receiver housing receiving at least a first implant and a second implant, an injection mechanism, including a pushing rod arranged upstream from the implants and configured to push the implants through the injection needle between an initial position and a final position in which the implants are injected, a pushing device for pushing on the pushing rod, configured to exert a force to move the pushing rod from the initial position to the final position, an intermediate stop device holding the pushing rod in an intermediate position and opposing the force exerted by the pushing device when a stroke of the pushing rod reaches a predetermined distance corresponding to a length of injection of the first implant, and an actuator for actuation by a user, configured to release the pushing rod from the intermediate position to the final position.
