Abstract: Image guided surgery includes capturing a primary modality image of a surgical field of a patient with a camera system, obtaining a secondary modality image of the surgical field registered to the primary image, generating a surgical guidance image based at least in part upon the secondary modality image, and projecting the surgical guidance image onto the patient. The surgical guidance image presents visual augmentations on or over the patient to inform a medical practitioner during a surgical procedure.

Abstract: A surgical probe is configured to be inserted into a body cavity and to emit beams of light to ablate tissue within the body cavity. The probe further includes sensors to detect properties of tissue in the body cavity and a source of suction to remove material produced by ablation of tissue within the body cavity. The sensors could be configured to operate in combination with beams of light emitted by the surgical probe to detect the location, geometry, fluorophore content, or other information about tissue in the body cavity. The surgical probe can additionally include suction port(s) to secure portions of tissue relative to the surgical probe to allow ablation of portions of the secured tissue and to allow detection of properties of portions of the secured tissue that are maintained in contact with the surgical probe by the suction port(s).

Abstract: A system for providing networked communications includes a plurality of head-mountable devices, each in communication with a control system via a communication network. Each of the plurality of head-mountable devices includes a display, and may also include an image-capture device and/or a microphone. The control system receives, via the communication network, surgical data of a patient obtained from at least one source of surgical data. Wearers of the head-mountable devices may select aspects of the surgical data and the control system causes those selected aspects to be displayed on the respective wearable device. The control system may also generate alerts and cause the alerts to be displayed on the wearable devices. An alert may include a notification that additional surgical data is available for access by the wearer of the head-mountable device.

Abstract: A system and method of tracking an error condition detectable in a communication network is provided. The method includes generating first derived communication attributes from collected statistics from the communication network in a first time interval and retaining the first derived communication attributes. The method further includes generating second derived communication attributes from collected statistics from the communication network in a second time interval, comparing values for the first and the second derived communication attributes to generate a comparison result and utilizing the comparison result as a factor in determining a status of the error condition.

Abstract: A crimping device for crimping a stent onto the inflation balloon of a stent delivery catheter. The device forms a crimp which creates regions of high frictional resistence between the stent and the inflation balloon. In one form, the crimp comprises a plurality of spaced grooves running the longitudinal length of the stent. In another form, the crimp is composed of a plurality of radial indentations spaced along the body of the stent. The device including an inner hub housing a plurality of radially spaced crimping jaws and an outer hub enclosing the jaws. The outer hub being rotatably connected to the inner hub and including means for forcing the jaws to move radially inwardly to crimp a stent.

Abstract: A stent crimping device for crimping a stent onto a balloon delivery-catheter of the kind typically used in percutaneous transluminal coronary angioplasty procedures. The device comprises a pair of plates bearing mutually opposed parallel ribs. The ribbed plates move in a direction such that a stepped circular crimp may be rolled onto a stent thereby firmly fixing the stent to a catheter balloon.

Abstract: An improved balloon catheter which includes bumpers located adjacent to the proximal and distal ends of the catheter balloon. The bumpers form a recessed pocket into which a stent crimped onto the catheter balloon is mounted. The recessed pocket formed by the bumpers securely retains the stent on the balloon and minimizes undesired contact between the stent and arterial walls and lesions during advancement of the stent within a patient's vasculature.
