A power transmission unit includes a second coil which contactlessly transmits power, a power reception unit includes a first coil that receives the power transmitted from the power transmission unit, and a medical instrument includes the power reception unit and is embedded in a body. The medical instrument includes a notification unit that is composed of a plurality of light emitting units that provides notification that a relative positional relationship between the power transmission unit and the power reception unit has reached a predetermined state by emitting light using the power received at the power reception unit when the predetermined state is reached by the movement of the power transmission unit. A soft unit into which an injection needle is inserted, the plurality of light emitting units being arranged so as to extend along an outer edge of the soft unit.

A cannulation chamber is provided for use with an arteriovenous graft including a flexible conduit. The cannulation chamber comprises an elongated body defining an annular passageway having a longitudinal axis extending between a first end and a second end. The body receives and surrounds the conduit in the passageway. The body comprises a self-sealing material and a cannulation port that exposes the self-sealing material. A flexible resilient elongated back plate is embedded in the body of the cannulation chamber such that the back plate extends generally parallel with and may partially surround the passageway. The back plate is formed of a substantially rigid material such that when a needle is inserted through the cannulation port and the self-sealing material, the needle is inhibited or prevented from extending through the back plate.

A device introduced small volumes of fluid for delivery to a patient through a fluid line. The device includes a first arm adapted to receive a syringe and a second arm fluidly connected to an upstream reservoir that defines an internal volume adapted to receive a volume of fluid. The device includes a fluid obstruction mechanism configured to selectably block flow of fluid from the reservoir toward the patient, wherein the fluid obstruction mechanism transitions between a first state that permits fluid flow from the reservoir toward the patient and a second state that directs fluid flow from the syringe into the reservoir while blocking fluid flow from the reservoir toward the patient.

A medical device comprising an access port locator configured to locate a subcutaneous access port located beneath a skin surface of a host, the access port locator including at least one annular ring having first and second opposing ends and a longitudinal access, the annular ring positionable on the skin surface of the host with the first end of the annular ring in contact with the skin surface and the longitudinal axis of the annular ring substantially perpendicular to the skin surface; at least one stabilizing flange configured to stabilize the access port locator on the skin surface, the stabilizing flange extending outward from the annular ring substantially perpendicular to the longitudinal access of the annular ring; and at least one need needle guard configured to shield a hand of a user of the access port locator when the hand is positioned on the stabilizing flange.

In one embodiment, a cerebrospinal fluid detection system includes a detection device including a detection compartment containing one or more indicators configured to indicate whether or not fluid received within the compartment contains cerebrospinal fluid and a port configured to pass fluid aspirated from a patient into the compartment.

An access port for providing subcutaneous access to a patient is disclosed. In one embodiment, the port includes an internal body defining a fluid cavity that is accessible via a septum. A compliant outer cover including silicone is disposed about at least a portion of the body. A flange is included with the port body and is covered by the outer cover. The flange radially extends about a perimeter of the port body proximate the septum so as to impede penetration of a needle substantially into the outer cover in instances where the needle misses the septum. The flange can further include both an anchoring feature for securing the outer cover to the port body and an identification feature observable via x-ray imaging technology for conveying information indicative of at least one attribute of the access port. The outer cover provides a suitable surface for application of an antimicrobial/antithrombotic coating.

In various embodiments, implants including reservoirs, such as intraocular lenses, feature flexible membranes and valves integrated therewith, the valves having apertures that are normally closed.

Described is a low voltage, pulsed electrical stimulation device for controlling expression of, for example, follistatin, a muscle formation promotion protein, by tissues. Epicardial stimulation is especially useful for heart treatment. Follistatin controlled release is also useful for treating other ailments, such as erectile dysfunction, aortic aneurysm, and failing heart valves.

An implantable vascular access port for providing repeated therapy to a patient in need of such therapy, the access port, upon repeated use, presents each time an access needle at a new location so as to minimize scarring injury to the skin of the patient. The vascular access port may include a body, a cover comprising a plurality of openings, at least one needle comprising a tip and a shaft, the shaft defining a lumen, a needle elevator mechanism to operate the position of the at least one needle in at least a retracted position in which the at least one needle is disposed in the body and the needle tip below the cover and an extended position in which the at least one needle is engaged through at least a first one of the openings, and a needle shift mechanism to move the at least one needle from a first position in which the needle can engage the at least a first one of the openings, to a second position in which the needle can engage at least a second one of the openings.

A venous access port assembly having a base, a peripheral surface, and a septum. The base defines an interior reservoir. The peripheral surface includes integrally molded X-ray discernable indicia identifying that the assembly is rated for power injection. The X-ray discernable indicia may extend through a height of the peripheral surface from a top surface to a bottom surface thereof. According to one aspect, the peripheral surface may be formed from X-ray discernable material, and the X-ray discernable indicia may be formed from the X-ray discernable material, or they may be formed by voids in the X-ray discernable material. According to another aspect, the peripheral surface may be formed from a radiotransparent or radiolucent material and applied with a radiopaque agent, and the X-ray discernable indicia may be one or more voids in the radiopaque agent or may be portions of the peripheral surface applied with the radiopaque agent.
