The present invention relates to a method for real time mechanical imaging of a prostate with a transrectal probe. In the method, generating a composite two- and three-dimensional prostate mechanical image from a plurality of partial mechanical images extracted from pressure response data and a probe orientation data starts with examining the prostate by pressing a probe head pressure sensor array against it at various overlapping locations. Merging of partial mechanical images together is accomplished by analyzing an overlap between each subsequent and previous partial mechanical image. Finding the prostate is assisted with a supplemental pressure response data indicating the location of a sphincter known to be about 4-5 cm away from the prostate. Data processing is improved by including probe orientation data to further increase the accuracy and sensitivity of the method. The probe is equipped with a two-dimensional head pressure sensor array, a supplemental shaft sensor array and orientation tracking sensors including a three-axis magnetic sensor and a two-axis accelerometer sensor for calculating elevation, rotation and azimuth angles of the probe.

A dynamic, adjustable annuloplasty ring sizer can include an adjustable ring replica, which can be adjusted through a range of sizes corresponding to available prosthetic annuloplasty repair ring sizes. Actuation of an adjustment trigger on a handle portion of the ring sizer can displace tension wires that extend through a malleable shaft and through a plurality of articulating segments that form the ring replica. Displacement of the tension wires causes flexion of the joints between adjacent articulating segments, thereby reducing the overall size of the ring replica. Releasing the tension wires can allow an elastic extension wire to act on the ring replica, enlarging the ring replica to its maximum, at-rest size. In this manner, the appropriate size of annuloplasty ring prosthesis can be determined with a single device, without requiring a plurality of static ring sizers that require individual insertion and placement for the conventional trial-and-error sizing methods. 1.

Принадлежит: Smith and Nephew Inc

Embodiments of the present disclosure are directed to instrumentation that facilitate coracoid-glenoid fixation in Latarjet procedures. For example, a single instrument, a coracoid resection tool, may be provided/utilized to prepare a coracoid bone graft for size, flatness, and hole drilling. A glenoid drill guide may further be provided/utilized that uses sized offsets for placement of the coracoid graft flush with the glenoid. Further embodiments of the disclosure are directed to corresponding methods that employ this instrumentation. For example, a surgeon may employs the coracoid resection tool as a guide to plane the inferior coracoid surface that will serve as the coracoid graft surface. The coracoid resection tool may further guide the placement of coracoid holes along the length of the coracoid and orient the holes approximately perpendicular to the planed coracoid graft surface. For example a proximal coracoid hole may be positioned towards the proximal end (i.e., the cut end) of the resected coracoid while a distal coracoid hole may be positioned towards the distal end (i.e., the tip) of the resected coracoid.

The present invention is directed to an all-fiber-optic scanning endomicroscope capable of high-resolution second harmonic generation (SHG) imaging of biological tissues. The endomicroscope has an overall 2.0 mm diameter and consists of a single customized double-clad fiber, a compact rapid two-dimensional beam scanner, and a miniature compound objective lens for excitation beam delivery, scanning, focusing, and efficient SHG signal collection. Endomicroscopic SHG images of murine cervical tissue sections at different stages of normal pregnancy reveal progressive, quantifiable changes in cervical collagen morphology with resolution similar to that of bench-top SHG microscopy. A device according to an embodiment of the present invention can also be used to assess other pathologies, such as cancer. fibrosis, and inflammation. The present invention allows for diagnosis, monitoring of the effect of therapeutics, and surgical or interventional guidance. The present invention enables visualization of histology in-vivo, in the patient, and is label-free. 1. A method of assessing preterm birth in vivo comprising:operating a fiber-optic scanning second harmonic generation (SHG) endoscopy imaging system;obtaining SHG endoscopy images of cervical collagen; anddetermining collagen fiber morphologies from the SHG endoscopy images.2. The method of further comprising identifying collagen fiber morphologies that include at least one selected from the group consisting of collagen fiber diameter claim 1 , volume claim 1 , porosity claim 1 , and fiber bending angle.3. The method of further comprising using a computing device to determine the collagen fiber morphologies.4. The method of further comprising determining abnormal changes in collagen fiber morphologies in order to determine a risk of pre-term birth.5. The method of further comprising operating the SHG endoscopy imaging system in situ claim 1 , in vivo claim 1 , and in real time.6. The method of further comprising operating ...
