Abstract: An electrical connector includes a plug that mates with a receptacle. In a medical application, the plug is connected to electrical leads that pass through a patient's skin to an implanted medical device in the patient's body, while the receptacle is connected to external medical equipment. The plug is small in diameter so the size of the opening in the patient's skin can be minimized. All electrical contacts in the plug are on internal portions. The receptacle includes annular contacts that contact the internal electrical contacts on the plug when the plug and receptacle are properly mated. When the plug is plugged into the receptacle, spring-loaded retention arms in the receptacle lock into place on the plug, retaining the plug in the receptacle.

Abstract: A coring tool and a dilator for defining an aperture in a tissue is presented. The system is preferably configured for generating an aperture within a ventricular wall for a method of implantation of ventricular assist devices (VAD's). The insertion tool/system includes a conduit device including a detachable dilator-coring tool and cuff which secures within a defined aperture in the tissue.

Abstract: In an aspect, a device includes a body structure including a core and a sleeve disposed around at least a portion of the core, the core defining a channel through the core extending from a first end of the core to a second end of the core, the sleeve including a flange adjacent the second end of the core; and a deployable portion coupled to the body structure adjacent the first end of the core, the deployable portion having a wired structure transitionable between a retained configuration and a deployed configuration, wherein a top portion of the wired structure extends beyond the first end of the core in a longitudinal direction when the wired structure is in the retained configuration, and wherein first end of the core extends beyond the top portion of the wired structure when the wired structure is in the deployed configuration.

Abstract: Cannula devices and related methods are provided. In accordance with one embodiment, a cannula ring includes a body portion having a substantially cylindrical member defining an opening therethrough. A plurality of anchor arms coupled with the body portion and configured to be positioned in a first, collapsed state and a second, deployed state, wherein the anchor arms each include a free end that is radially displaced from the body portion while in the second, deployed state relative to their positions while in the first, collapsed state. Suture rings and other associated structures and devices are also described.

Abstract: A heart assist device comprising a rotary pump housing having a cylindrical bore, a pumping chamber and a motor stator including an electrically conductive coil located within the housing and surrounding a portion of the cylindrical bore. A rotor has a cylindrical shaft with an impeller and one or of magnets located within the shaft that are responsive to the motor stator to drive actuation of the rotor. The housing bore is closely fitted to the outer surface of the shaft forming a hydrodynamic journal bearing with an annular clearance defining a leakage flow path. One or more of radial or axial thrust bearings may be provided to provide rotation stability to the rotor and flow within the leakage flow path. The relative orientation of positions of the inflow, outflow, and leakage flow paths may be varied within the pump, such as to accommodate different intended methods for implantation and/or use.
