An apparatus includes a base portion configured to selectively couple with a robotic arm. A shaft extends distally form the base portion and terminating into a distal end. A sleeve is slidably coupled to the shaft. A colpotomy cup is fixedly secured to a portion of the sleeve. A plurality of sensors are configured to locate the position of the sleeve relative to one or more anatomical features of a patient.

Systems, methods, and devices allow intravascular or percutaneous mapping, orientation and/or ablation, in bodily cavities or lumens. A device includes elongate members, moveable between an unexpanded configuration and an expanded or fanned configuration. The elongate members form a stack in the unexpanded configuration to fit through a catheter sheath. The elongate members follow respective arcuate or curvilinear paths as advanced from the sheath into the bent or coiled stack configuration, adopting volute, scroll or rho shapes, and may be nested. The elongated members are fanned or radially spaced circumferentially with respect to one another into the expanded or fanned configuration. Transducer elements carried by elongate members sense various physiological characteristics of or proximate tissue, and/or may apply energy to or proximate tissue. The elongate members are rotatable in groups or as a group in the expanded configuration. The device is retractable.

A navigation, tracking and guiding system for the positioning of operatory instruments inside the body of a patient. The system includes a control unit, a viewer and detecting means for determining the spatial position of the viewer. The system further includes a sensor associated to an operatory instrument and insertable inside the internal portion of the body of the patient. The control unit is configured to project on the viewer an image of the state of the internal portion.

An orthopedic distraction device is provided. The orthopedic distraction device includes a first upper paddle for engaging a first bone of a joint, a lower paddle for engaging a second bone of the joint and a displacement mechanism. The displacement mechanism includes a drive assembly operable to move the upper paddle relative to the lower paddle. The lower paddle is releasably connected to the displacement mechanism.

Ablation and visualization systems and methods to access quality of contact between a catheter and tissue are provided. In some embodiments, a method for monitoring tissue ablation of the present disclosure comprises advancing a distal tip of an ablation catheter to a tissue in need of ablation; illuminating the tissue with UV light to excite NADH in the tissue, wherein the tissue is illuminated in a radial direction, an axial direction, or both; determining from a level of NADH fluorescence in the illuminated tissue when the distal tip of the catheter is in contact with the tissue; and delivering ablation energy to the tissue to form a lesion in the tissue.

A device positionable in a cavity of a bodily organ (e.g., a heart) may discriminate between fluid (e.g., blood) and non-fluid tissue (e.g., wall of heart) to provide information or a mapping indicative of a position and/or orientation of the device in the cavity. Discrimination may be based on flow, or some other characteristic, for example electrical permittivity or force. The device may selectively ablate portions of the non-fluid tissue based on the information or mapping. The device may detect characteristics (e.g., electrical potentials) indicative of whether ablation was successful. The device may include a plurality of transducers, intravascularly guided in an unexpanded configuration and positioned proximate the non-fluid tissue in an expanded configuration. Expansion mechanism may include helical member(s) or inflatable member(s).

A method for deforming a staple comprising a base, a first staple leg, and a second staple leg, wherein the base, the first staple leg, and the second staple leg are positioned within a common plane prior to being deformed, the method comprising positioning the first staple leg within a first cup of a staple pocket, the first cup comprising a first inner surface, applying a first compressive force to the first staple leg to bend the first staple leg toward the base and the second staple leg, contacting the first inner surface with the end of the first staple leg to bend the end of the first staple leg toward a first side of the base, and deforming the first staple leg such that the end of the first staple leg crosses a mid-line of the staple defined between the first staple leg and the second staple leg.

An apparatus for treating vascular thrombosis with ultrasound, includes a therapeutic ultrasonic transducer, suitable for generating focused ultrasonic waves that propagate along an emission axis; an imaging ultrasonic transducer associated with the therapeutic transducer; a means for moving the focal spot of the therapeutic ultrasonic transducer along the emission axis with respect to the imaging transducer; a motorized mechanical system for translating the transducers along at least a first axis parallel to the emission axis and a second axis perpendicular to the first; and an electronic control system for driving the motorized mechanical system and the means for moving the focal spot of the therapeutic transducer.

A strain gauge (10, 40, 50), a pressure sensor (20, 60), and an interventional medical catheter. The strain gauge (10, 40, 50) comprises a substrate (11) and at least two sensitive gages (1, 2) provided on the substrate (11), the at least two sensitive gages (1, 2) being arranged along two mutually perpendicular directions and sharing one ground port (3). The pressure sensor (20, 60) comprises an elastomer (21, 61) and the strain gauge (10, 40, 50) provided on the elastomer (21, 61). The interventional medical catheter comprises a catheter distal end and the pressure sensor (20, 60) provided at the catheter distal end. The present application not only saves the trace space for mounting and using the strain gauge (10, 40, 50) on the interventional medical catheter, facilitating the successful mounting and use of the strain gauge (10, 40, 50) on the interventional medical catheter, improving the adaptability of the strain gauge (10, 40, 50), but also reduces the size of the strain gauge (10, 40, 50), thereby shortening the length of the elastomer (21, 61) of the pressure sensor (20, 60) and reducing the size of the interventional medical catheter.

A vapor delivery system and method is provided that is adapted for treating prostate tissue. The vapor delivery system includes a vapor delivery needle configured to deliver condensable vapor energy to tissue. In one method, the vapor delivery system is advanced transurethrally into the patient to access the prostate tissue. The vapor delivery system includes a generator unit and an inductive heating system to produce a high quality vapor for delivery to tissue. Methods of use are also provided.
