    摘要： An implantable lead has a lead body construction designed to accommodate loading forces exerted on the lead body during patient movement. The lead body may be sufficiently stretchable to resist forces that could otherwise cause lead failure, axial migration of the electrodes, anchor damage, or tissue damage. Increasing stretchability of a lead body can also increase the vulnerability of the lead body to flex fatigue, buckling fatigue, kinking, and crush. Therefore, the lead described herein includes a coiled wire embedded between a first insulative layer and a second insulative layer of an outer jacket of the lead body to improve column stiffness and kink resistance.

    摘要： Systems for coupling a catheter(50) to a medical device port (40) and methods for relieving stress on a catheter coupled to a medical device port. Exemplary systems may include both a seal (60) attached at or near a proximal end of the catheter, and a tubular restraint (20). The restraint may include a first interlocking surface formed on the interior surface at or near the proximal end that engages a second interlocking surface associated with the port. The system may also include a locking sleeve(10) to secure the restraint in the desired position. Exemplary methods may include: coupling the port to the proximal end of the catheter and associated seal; sliding the restraint over the seal; and engaging the first and second interlocking surfaces.

    摘要： Low profile inlet valve embodiments for a piston pump therapeutic substance infusion device are disclosed that reduce dead volume, occupies little residential space, operates rapidly, and have many other improvements. The therapeutic substance infusion device has a housing, a therapeutic substance reservoir, a power source carried in the housing, electronics, a piston pump, and an inlet valve. The piston pump is configured for pumping therapeutic substance from the therapeutic substance reservoir through an infusion port at a programmed rate. The inlet valve is in fluid communication with a reservoir outlet to control the flow of therapeutic substance into the piston pump. The inlet valve has a substantially coplanar valve surface and valve spring. Many embodiments of the low profile inlet valve and its methods of operation are possible.
