An adaptable suction tubing apparatus for a surgical retractor is disclosed. The suction tubing apparatus comprises a suction tip connector, an extruded rectangular tubing and an end suction connector. All components also have side protrusions or bumps for nesting into top channels over the top surface of a surgical retractor. These side protrusions provides snug fit within a surgical retractor. Optionally the tubing can have double sided adhesive tape for placement over the top surface of a standard surgical retractor. The suction tubing apparatus is designed for one time use and has low profile and conformed to the contour of any retractors perfectly.

Medical devices and methods for making and using medical devices are disclosed. An example medical device may include a medical device for measuring blood pressure. The medical device may include an elongated shaft having a proximal region and a distal region. An optical fiber may extend along the proximal region. The optical fiber may be secured to an inner surface of the shaft. An optical pressure sensor may be coupled to the optical fiber. The optical pressure sensor may be disposed along the distal region. A sealing member may be attached to the optical fiber and may have a surface engaged with the inner surface of the shaft.

A channel retractor with one or more gate tracks to receive one or more slide gates to hold one or more extended retractors away from the surgical access channel running through the extended retractor. The distal ends of the one or more extended retractors held by the one or more slide gates holding tissue distal to the end of the channel retractor to maintain an extended access channel beyond the distal end of the channel retractor. The channel retractor assembly may be used to hold open an extended access channel through the psoas muscle to allow access to the spine or through other tissue in other surgical access techniques.

A wide angle illumination system and method. The wide angle illumination system is efficient in facilitating wide angle illumination of interior surfaces during vitreoretinal surgery. An optical fiber terminates in a convex semi-spherical end. A light source transmits a light beam through the optical fiber toward the convex semi-spherical end. An optical element has a flat, straight or planar end that is opposite to and adjoins a convex semi-spherical end which is adjacent to and which faces the convex semi-spherical end of the optical fiber. The light source transmits a light beam through the optical fiber convex semi-spherical end to the semi-spherical end of the optical element after which the convex semi-spherical end of the optical element transmits and diverges the light beam through the flat planar end into the interior of a surgical surface.

A method of atraumatically hydrodissecting and maintaining endothelial function and structure of a vascular target includes forming an incision in tissue proximate one end to realize an insertion space, inserting a distal end of a cannula and/or endoscope into the insertion space and while visualizing the vascular target, ejecting a hydrodissecting fluid from the distal end of the cannula and/or endoscope to substantially separate or dissect the vascular target from the surrounding tissue, while advancing the distal end through the space as it is enlarged by the hydrodissecting fluid, to a distal target end of the vascular target. The hydrodissecting fluid is formulated to minimize or prevent formation of microthrombi in the hydrodissected vascular target. The hydrodissecting fluid is a water-based vascular graft treatment solution and can include any of a balance salt solution, a metallic salt solution, such as Plasma-Lyte® A, a vascular graft treatment solution, such as Duragraft® solution, L-Arginine, aspirin and low molecular weight heparin.

A lesion detection system for use with a patient, comprising an optoacoustic guide wire assembly configured to be insertable into a patient's tissue. The optical acoustic guide wire assembly can be comprised of an optical waveguide have a first end and a second end, a light source coupled to the second end of the optical waveguide, wherein said light source configured to emit energy to the patient's tissue, at least one transducer configured to detect an ultrasound signal emitted from the patient's tissue in response to energy emitted from the light source, and a computer system.

Systems and methods are provided in which devices that are employed during a medical procedure are adaptively configured during the medical procedure, based on input or feedback that is associated with the current state, phase or context of the medical procedure. In some example embodiments, the input is obtained via the identification of one or more medical instruments present within a region of interest, and this input may be employed to determine configuration parameters for configuring the device. In other example embodiments, the input may be based on the image-based detection of a measure associated with the phase or context of the medical procedure, and this input may be employed to adaptively control the device based on the inferred context or phase of the medical procedure. In other embodiments, images from one imaging modality may be employed to adaptively switch to another imaging modality.

Systems, devices, and methods for identifying a target in a body using a spectroscopic feedback from the target are disclosed. An exemplary surgical feedback control system comprises a feedback analyzer configured to receive a reflected signal from a target in response to electromagnetic radiation directed at a target, and a controller in operative communication with the feedback analyzer. The controller can generate a control signal to a surgical system to perform a predetermined operation based upon the received reflected signal, including determining a composition of the target, or programming a laser setting to direct laser energy to the target.

A system for accessing a central pulmonary artery includes an elongate, flexible tubular catheter, having a proximal end, a distal end and a catheter hub on the proximal end. An elongate, flexible rail has a proximal end, a distal end and a rail hub on the proximal end. The rail has a distal advance segment which extends at least about 10 cm beyond the distal end of the catheter when the catheter hub is adjacent the rail hub.

An optical coupling efficiency detection assembly includes a first housing accommodating a beam splitter and a fiber port, a second housing accommodating a ferrule enclosing a monitoring fiber, and an attachment block attaching the first housing to the second housing to establish a parfocal arrangement among the beam splitter, the fiber port, and the ferrule. Further, an assembly method for the optical coupling efficiency detection assembly is disclosed. The assembly method may include providing a beam splitter and a fiber port in a first housing, providing a ferrule enclosing a monitoring fiber in a second housing, and attaching the second housing to the first housing via an attachment block to establish a parfocal arrangement among the beam splitter, the fiber port, and the ferrule.
