摘要： Embodiments of endo-illuminators and related methods are disclosed. One embodiment of an illuminator can comprise a cannula defining a passage, an optical element disposed at an end of the cannula, and an optical fiber running through the passage with the distal end of the optical fiber in contact with the optical element. The optical fiber includes at least a heat preconditioned distal portion that terminates in the distal end that is in contact with the optical element. One embodiment of a method can comprise inserting an optical fiber through a proximal portion of a cannula and optical element assembly until the distal end of the optical fiber contacts the optical element, heating a distal portion of the optical fiber to between a softening temperature and a melting temperature for a period of time to cause the distal portion to axially shrink and moving the optical element so that the optical element is in contact with the distal end of the optical fiber when the distal portion of the optical fiber has axially shrunk. Moving the optical element so that the optical element is in contact with the distal end of the optical fiber when the distal portion of the optical fiber has axially shrunk can comprise applying a force to the cannula and optical element assembly to maintain the optical element in continuous contact with the distal end of the optical fiber while the optical fiber axially shrinks.

摘要： A portable, ambulatory infusion pump for use with standard pre-filled infusion medicament containers is powered by a miniature compressed gas cylinder coupled to a mechanical pressure regulator which supplies regulated gas at a substantially constant pressure to an inflatable bladder. The bladder is positioned between a substantially rigid pressure surface and a moveable pressure transfer plate and pushes against the transfer plate when inflated. A pre-filled medicament container is positioned over the pressure transfer plate and is squeezed between the transfer plate and the pump housing cover as the plate is displaced in response to inflation of the flexible bladder. A safety interlock assembly is connected between the pressure regulator and the inflatable bladder and prevents inflation of the bladder unless the housing cover is completely closed. Upon inadvertent opening of the pump, the internal pressurization system is vented to atmosphere.

摘要： A medical access device is adapted to receive an instrument and comprises a housing defining an inner channel and a valve disposed in the channel to form a seal with the housing. The valve includes an outer wall and a pair of inner walls extending in distally converging relationship to define a slot. At least one compression member extends between the outer wall and an associated one of the inner walls. The compression member is compressed in response to insertion of the instrument and exerts a force on the associated inner wall when compressed to reduce leakage of the valve when the instrument is inserted. A funnel is provided at the distal end of the valve to facilitate backloading of the instrument.

摘要： The present disclosure relates to a multi-core optical fiber cable (MCF). In some embodiments, an MCF comprises a plurality of cores, a cladding surrounding the plurality of cores, wherein a refractive index of one or more of the plurality of cores is greater than a refractive index of the cladding, and a coating surrounding the cladding, a distal end free of the coating and having a reduced diameter. The MCF also comprise an annular gap formed between the distal end of the MCF and the inner surface of the cannula, wherein the concentricity of the distal end of the MCF with the inner passage of the cannula is maintained.
