  • Patent number: 8215013
    Abstract: Connector assemblies for use with implantable medical devices having easy to assemble contacts are disclosed. The connector assemblies are generally formed by coupling a plurality of ring contacts, sealing rings, and spring contact elements together with at least one holding ring to form a connector having a common bore for receiving a medical lead cable. Contact grooves or spring chambers for positioning the spring contact elements are formed in part by assembling multiple components together. A further aspect is a provision for encasing each connector assembly or stack inside a thermoset layer or a thermoplastic layer before over-molding the same to a sealed housing.

  • Publication number: 20120034804
    Abstract: The present device, system, and method pertain to locking and/or latching mechanisms that utilize canted coil springs and specific groove geometries in connecting parts to achieve locking and/or latching. In specific locking and/or latching embodiments. built in release features are provided to enable unlatching even after being locked, such as by moving in the opposite direction as when moving the connector to lock. Unlatching can implemented by rotating the spring to permit moving in the opposite direction.

  • Publication number: 20110280653
    Abstract: A connector includes a canted coil spring, a multi-piece housing, and an insert element. The multi-piece housing includes a first housing part defining a bore of the housing, and a second housing part connected to the first housing part and comprising a tapered wall defined by a first section of the second housing part with a first inner diameter and a second section of the second housing part with a second inner diameter greater than the first inner diameter. A groove is formed in the bore by the connection of the first housing part with the second housing part, the groove having at least a portion of the canted coil spring disposed therein and having a tapered side wall formed at least partly by the tapered wall of the second housing part. The insert element is insertable into the bore to engage the canted coil spring for connection with the housing.

  • Patent number: 8052459
    Abstract: A connector is provided that permits locking between a pin and a housing a canted coil spring yet permit separation by allowing turning of the canted coil spring so that the canted coil spring can compress along the minor axis. In one example, the connector incorporates two grooves on the pin to allow the rotation. In another example, the connector incorporates two grooves in the bore of the housing to allow the rotation. The connector may be used in a number of applications or industries, such as for aerospace, automotive, and medical device industries, to name a few.

  • Publication number: 20110037234
    Abstract: The present cartridge seal assemblies pertain to rotary lip-type seals. In certain embodiments, a sealing member is constructed of a relatively hard material that increases the lifespan of the sealing member. The sealing member is energized with a canted-coil spring, which in some embodiments includes an adjustable spring force. The present embodiments enable control of sealing force to achieve an appropriate sealing force between the sealing member and the shaft based on factors such as temperature, pressure, rotary speed, properties of fluid media, etc. to achieve longer seal life.

  • Publication number: 20100029145
    Abstract: A canted coil spring made from multi-metallic wire to achieve combinations of desired material characteristics of different metals is discussed. Wire to be used in canted coil springs can have two or more metals oriented co-axially along such wire, such as an outer layer of one metal having one set of properties, and a core of a different metal having a different set of properties, that will achieve a single solid, multi-metallic wire with enhanced performance over a single material canted coil spring. Such features may be found advantageous in electrical applications, such as where both high electrical conductivity and high strength properties are desired.
