摘要： A catheter includes a spring having a plurality of convolutions disposed along a longitudinal axis, and a first modulus. A sheath overlying the spring engages the convolutions of the spring and imparts to the spring axial compressive stresses which increase the modulus of the spring. The catheter can be manufactured by inserting the spring into a tube of Hytrel.RTM. material, stretching the tube at a transition region which advances along thhe tube causing the tube to neck down onto the spring. The stretching develops internal stresses which are utimately imparted to the spring thereby increasing the modulus of the catheter.

摘要： An apparatus is provided for sealing around shafts or tubes of varying diameter. Its basic element comprises an elastomeric sealing body with an axial passage which is radially compressed from more than two sides to compress the passage into sealing engagement with a member extending through the passage. Radial compression is achieved by cams and followers disposed around the body which cooperate with angularly spaced radially extending lugs formed integrally with the body. The cams are spring biased to normally compress the axial passage of the sealing body. Levers operable by one hand of the user are provided to selectively release the apparatus.

摘要： A hand-held and operated pneumatically powered device for injecting fluids, such as in medical applications, consisting of a housing that is sized and shaped to be hand held, and connected power and infusion assemblies contained within the housing. The power assembly includes a sealed vessel containing pressurized gas, a lever-needle vessel-puncturing mechanism, a gas flow path leading from the needle to the infusion assembly, and pressure regulator and pressure relief mechanism (which may include a pneumatic flow control orifice) interposed in the flow path. The infusion assembly includes a two-way valve for exhausting the gas or directing it into a power chamber for receiving the gas connected in tandem with an infusion chamber that holds the infusate, a two-headed piston contained within and spanning the two chambers with one of its heads in contact with the pressurized gas and the other in contact with the infusate, and a throttle mechanism at the outlet of the infusion chamber for regulating the pressurized flow of infusate into and out of the infusion chamber by means of a two-way valve. A pressure gauge may be provided for measuring the pressure of the infusate.In one embodiment, two power infusion devices are coupled together with a common pressurized gas source and are also coupled together at their outlets for providing two different infusates to the proximal and distal ends of a catheter. A ball valve is utilized to purge the infusates of entrapped gas.

摘要： A spring clip including parallel jaws carried by telescopically interengaged carrier members. The jaws are spring biased toward one another by a compression coil spring captured between opposed end caps on the carrier members. One of the carrier members has diametrically aligned slots formed through opposed side walls thereof to enable the other member to passed through said slots and snapped into telescopic receipt within said one member. The end caps are formed integrally with the carrier members. In assembly of the clip, the carrier members are passed into telescopic engagement with the end caps in place and the compression coil spring interposed between the end caps.

摘要： A package for a catheter having a proximal end and a distal end, includes a tube defining a cavity along an elongate axis, the cavity being configured to receive at least the distal end of the catheter. Access means includes a housing fixed to the proximal end of the tube and a cap rotatable to engage the housing in a first position to seal the cavity, and to disengage the housing in a second position to provide access to the cavity. A circumferential tear-strip is configured and disposed to provide a high degree of control over the separation of the housing and cap. An O-ring, which forms a seal between the cap and housing, is disposed relative to a circumferential shoulder which cooperates with a camming surface to cause the cap to pop from the housing when rotated. An associated method includes the steps of rotating the cap a first angular distance to engage the camming surface and a second angular distance to cause the O-ring to traverse the shoulder.

摘要： A manually driven syringe for injecting fluids under high pressure is described that includes a barrel (12), a plunger (13) that is received within the barrel and extends rearwardly through an aperture (28) in the body (27) of a handle (14) which carries a pair of opposed finger grips (19, 22). The finger grips are located rearwardly of the barrel and laterally of the shaft (19) of the plunger, elongated so as to each accommodate two fingers, and angled rearwardly. This design minimizes the distance between (a) the inner edges of the grips and (b) the grips and the head of the extended plunger, thus making the syringe easier to grip in the palm of the hand and enabling the syringe to be gripped strongly between the fingers and the palm.
