    摘要： This invention provides an inventive tissue sampling probe which offers many advantages over probes available in the prior art. Unexpectedly superior results are obtained in connection with the retrieval of intact tissue specimens, because of a unique combination of cutting features, including, for example, the employment of an electrosurgical cutting element and a vacuum assist in one preferred embodiment. A particularly important feature of the invention is the ability to manipulate the electrosurgical cutting element to cleanly sever the distal end of the tissue specimen. In certain embodiments, this is accomplished without any cutting impact on surrounding tissue. The versatility of the invention permits its use in many applications, including, for example, breast biopsies, laparoscopic surgery, and lymphadenectomy procedures.

    摘要： This invention provides an inventive tissue sampling probe which offers many advantages over probes available in the prior art. Unexpectedly superior results are obtained in connection with the retrieval of intact tissue specimens, because of a unique combination of cutting features, including, in particular, the employment of an electrosurgical cutting element which is extendible to permit ready severance of the distal end of the tissue specimen, without impact to surrounding tissue. Additionally, the inventive instrument is advantageously designed so that portions of the instrument which contact the patient's tissue or fluid discharge (i.e. blood) during a procedure are modular and disposable, to permit ready replacement of those portions with a new module for an ensuing procedure, without the necessity of cleaning and sterilizing the instrument. The versatility of the invention permits its use in many applications, including, for example, breast biopsies, intraoperative staging, laparoscopic surgery, and lymphadenectomy procedures.

    摘要： A device includes three elements fabricated on a common substrate. The first element includes an active waveguide structure having at least three sub-layers supporting a first optical mode. The second element has a passive waveguide structure supporting a second optical mode, and the third element, butt-coupled to the first element, has an intermediate waveguide structure supporting intermediate optical modes. One sub-layer in the active waveguide structure includes an n-contact layer, another sub-layer includes a p-contact layer, and a third sub-layer includes an active region. A tapered waveguide structure in at least one of the second and third elements facilitates efficient adiabatic transformation between the second optical mode and an intermediate optical mode. No adiabatic transformation occurs between that intermediate optical mode and the first optical mode. Mutual alignments of the three elements are defined using lithographic alignment marks that facilitate precise alignment between layers formed fabrication of the elements.

    摘要： A device comprises three elements, realized as photonic integrated circuits. The first element comprises a tunable semiconductor laser emitting light at a laser output wavelength. The second element comprises a wavelength selective element, coupled to the first element. The third element comprises N photodetectors where N>=2, coupled to the second element. Light coupled into the second element from the first element is de-multiplexed by the wavelength selective element such that a ratio of light power coupled from the second element into one of the N photodetectors to light power coupled from the second element into another one of the N photodetectors is a function of the laser output wavelength. The responses of the N photodetectors facilitate at least one of measurement and control of the laser output wavelength.

    摘要： A device comprises three elements. The first element, comprising an optical gain structure and a laser cavity mirror structure, couples light to the second element, comprising a phase tuner. The second element couples phase tuned light to the third element. The third element, comprising an optical resonator with first and second coupler/splitter structures, provides a primary optical output from the second coupler/splitter structure. Light coupled into the optical resonator through the first coupler/splitter structure and then coupled out of the optical resonator though the first coupler/splitter structure is injected back into the optical gain structure through the second element. Light coupled out of the optical resonator through the second coupler/splitter structure is provided as the primary optical output. Characteristic of the coupler/splitter structures and the optical resonator are selected such that the light injected back into the optical gain structure reduces linewidth, and noise in primary optical output is suppressed.

    摘要： A bone anchor insertion device comprises a handle, a nosepiece connected to a distal end of the handle, a bone anchor connected to the nosepiece, and an actuator disposed on the handle for deploying the bone anchor, which suture is also fixed to a portion of soft tissue to be attached to a portion of bone. A suture ratchet or tensioning mechanism is disposed in the handle for tensioning suture which is associated with the bone anchor. This mechanism permits precise tensioning, while also permitting one-handed operation, thereby allowing the practitioner to use his or her other hand for other activities, such as camera operation or the like.
