A microsurgical probe employs an optional probe support structure; an optical fiber for providing a feed path for an emission wavelength; a chemical feed path for delivering a chemical; a resonator motor; and a probe accessory tool. A microsurgical system additionally employs a sensor and an artificial intelligence (AI) system to assess conditions based on data provided by the sensor. The system can be employed to remove tumor tissue that is interwoven with healthy tissue. This system can also be employed to fertilize old, inflexible ova.

The present invention relates to a flexible surgical system for endoscopic spinal decompression and methods thereof. Various methods of accessing the epidural space with this instrument are described. The system design enables placement of the device through several approaches. It is then advanced under direct visualization or fluoroscopic (X-Ray), for example, into areas of the spine including lumbar (low back), thoracic (mid and upper back) and cervical (neck). The pathologies encroaching upon the spinal space can then be visualized wherein the epidural membrane can optionally be displaced to further aid in visualization. The membrane can be used to protect regions of tissue adjacent the site to tissue removal.

An optical fibre for an ultrafast laser endoscope including at least the following structures: a hollow core, the periphery of which has an order of symmetry of at least six when considering axes of symmetry passing through the centre of the core and through the centre of convex shapes, seen from the centre of the core, the convex shapes at least partly making up the periphery of the core; an intermediate layer of cellular structure surrounding the core; a lightconducting peripheral structure surrounding the intermediate layer of cellular structure; and an outer sheath surrounding the light-conducting peripheral structure. A particular advantage of the optical fibre is that it optimizes the emission of a high-power flux associated with fluorescence collection.

An apparatus, system or device and methods for applying one or more stimuli to an implantation, occlusive device, or embolization are described. The implantation can include a polymer or polymer composition such as a hydrogel and can be used for sterilizing a subject in need of contraception by occluding the vas deferens, fallopian tube(s), or uterus, but can also be used to occlude, in whole or part, any other body ducts or organs. The one or more stimuli can modify the occlusion so that is removed from the body lumen in situ, there by reversing the contraception or other effects of the occlusion.

Devices, systems, and methods for placing orthopedic implants are disclosed. In one aspect, a tool for laser assisted placement of an orthopedic implant includes a cannulated body having a proximal end and a distal end. The cannulated body includes an inner channel extending between the proximal and distal ends. The tool also includes an optical cable arranged within the inner channel of the cannulated body, and a tip arranged at the distal end of the cannulated body. The tip is configured to allow passage of laser radiation through the distal end of the cannulated body.

An optical fibre assembly (10) disposed within a catheter (12) for ablating mammalian, such as heart tissue. The optical fibre assembly has a plurality of optical cores (16A-16C), each core defining a leading end and a trailing end and being adapted to carry an optical imaging beam. An optical lens arrangement (25) is operatively connected to the leading end of the plurality of optical cores for causing divergence of the light beams emitted therefrom. The optical fibre assembly (10) creates a field of view by directing a plurality of said optical imaging beams onto a tissue portion and capturing a reflected portion of said beams. The divergence of the beams provides a greater field of view than may otherwise be provided.
