    摘要: A method of surgery including bending a multi-purpose surgical implement handle that has proximal and distal ends. A gripping section is located toward the proximal end, and an attachment section is located toward the distal end. An adjusting section is interposed between the gripping section and the attachment section. The adjusting section may be bent by a human user at virtually any discrete location along the section. The adjusting section may include an increased-adjustability portion which is easier to bend than other portions of the adjusting section. The method includes attaching a surgical implement to the attaching section of the handle, and bending the adjusting section at least once prior to inserting the implement through a surgical opening to a surgical field. The method further may include bending the adjusting section more than once to form multiple bends therein.

    摘要: Surgical apparatus and associated methods of use are provided for retracting tissue around an incision. The apparatus includes a member having an inner peripheral surface and an outer peripheral surface. An adjustable aperture is definable within the inner peripheral surface as the member is adjusted between a compressed condition in which the aperture is substantially closed and an expanded condition in which the aperture is substantially open. The apparatus is positioned within a surgical incision in the compressed condition, and is adjusted to the expanded condition in situ to define an opening within the incision through the aperture whereby a surgical field may be viewed and/or accessed.

    摘要: A biological valvular prosthesis defined by a chemically fixed biological derived conduit having at least one integrally formed tissue valve. The chemical fixation of the valve ensures that the leaflets remain open under normal forward blood flow conditions, but close under minimal backflow pressure. The biological valvular prostheses are useful in the replacement of venous valves and other biological valves. The biological valvular prosthesis may also be in the form of a tubular conduit bearing one tissue valve. This valvular conduit prosthesis is useful for the reconstruction of the pulmonary artery to correct various types of congenital defects.

    摘要: A tubular prosthetic semilunar or atrioventricular heart valve is formed by cutting flat, flexible leaflets according to a pattern. The valve is constructed by aligning the side edges of adjacent leaflets so that the leaflet inner faces engage each other, and then suturing the leaflets together with successive stitches along a fold line adjacent the side edges. The stitches are placed successively from a proximal in-flow end of each leaflet toward a distal out-flow end. During operation, when the leaflets open and close, the leaflets fold along the fold line. Distal tabs extend beyond the distal end of each leaflet. The successive stitches terminate proximal of the distal tab portion so that no locked stitches are placed along the distal portion of the fold line. The tab portions of adjacent leaflets are folded over each other and sewn together to form commissural attachment tabs. The commissural tabs provide commissural attachment points to accommodate sutures and the like in order to secure the tab to a vessel wall, if a semilunar valve, and papillary muscles and/or chordae tendineae if an atrioventricular valve.

    摘要: A control system includes a rate-damping loop that uses a calculated angle-of-attack error to non-linearly scale a rate-feedback signal so that at lower angle-of-attack (AOA) error values, an acceleration feedback term plays a greater role in pitch compensation, while at greater angle-of-attack error values, a rate-feedback term plays a greater role in the pitch compensation. In some embodiments, a control system and method of controlling an angle-of-attack of a moving body are provided. A signal representing an angle-of-attack error is non-linearly combined with a signal representing a rate-of-change of an estimated angle-of-attack to generate a non-linear rate-damping signal. The non-linear rate-damping signal is subtracted from the signal representing the angle-of-attack error to generate a signal to control one or more elements of the moving body.

    摘要: An indicator on a film cartridge to indicate whether a film cartridge has been used in a photographic camera. The film cartridge includes a spool having an elongate coaxial hole open at one end. An indicator, disposed within the coaxial hole, is deformable from a first state to a second state in response to the film cartridge being received by a plunger in the photographic camera; the second state being visually different than the first state. The indicator has a continuous, non-punctured, non-fractured configuration when in both the first and second states.

    摘要: An apparatus for sodding onto the inner lumenal surface of a synthetic graft of harvested and concentrated microvessel endothelial cells from liposuctioned fat tissues, which harvested cells are formed into a "pellet" of isolated endothelial cells in loose aggregations, includes a sodding tube having a single rigid outer wall bounding a sodding chamber. A filter pack assembly is provided to communicate the pellet of cells from a processing vessel to the graft. This filter pack assembly includes a series of successively finer filter members cooperatively defining a series of turbulent-flow chambers in which aggregations of cells too large to pass through a particular filter are exposed to liquid flow turbulence which is effective to break up the aggregations. A check valve assembly ensures that liquid flow is unidirectional so that sodding of the cells onto the inner lumenal surface of the graft is not interfered with by possible liquid reflux, and sodded cells are similarly not dislodged from the graft by such liquid reflux.
