A vein imager includes: two photodetectors, a first and second lasers configured to respectively emit an infrared beam of light and a human-visible beam of light; a combiner to coaxially align the two beams; and a scanner that scans the coaxial beam in a pattern and onto a skin surface of a patient. The first photodetector receives the infrared wavelength reflected from the patient as a contrasted image of subcutaneous veins, and surface reflection noise due to skin surface topology, and outputs a first signal representing that contrasted image of subcutaneous veins and noise due to skin surface topology. The second photo detector receives the human-visible wavelength reflected from the skin surface and outputs a second signal representing a contrasted image of the topology. The second signal is subtracted from the first signal to remove the noise, permitting projection of a surface-noise-free vein image onto the skin surface.

Micro vein enhancer with two lasers and two optical detectors configured for removing surface topology

An apparatus includes a body, and anchoring feature, and a guide feature. The body is sized and configured to be positioned on an eye of a patient. The anchoring feature is configured to secure the body to the eye of the patient. The guide feature is configured to guide a cannula into a scleral incision formed in the eye of the patient along a path that is substantially tangential relative to the eye of the patient. The guide feature is sized and configured to allow the cannula to pivot laterally through a range of angular motion at the scleral incision.

Ocular cannula guide

An apparatus includes a body and a pair of rigid legs extending from the body. The body includes an engagement feature configured to engage a deployment instrument. The legs are parallel with each other. Each leg has a sharp tip. The legs both extend along a plane. The body defines a guide opening. The guide opening is oriented transversely relative to the plane associated with the legs. The guide opening is sized to receive a cannula having a generally flat profile. The guide opening is configured to guide the cannula through a sclerotomy at a substantially tangential orientation.

Guide apparatus for tangential entry into suprachoroidal space

An apparatus includes a body, a needle, a catheter, and an actuator assembly. The needle extends distally from the body. The needle has an inner wall defining a needle lumen. The needle lumen is in fluid communication with a fluid port of the body. The catheter is slidably disposed in the needle lumen. The catheter has a catheter lumen. The first actuator assembly is configured to translate the catheter within and relative to the needle. The apparatus may also include an actuator assembly that is configured to rotate the needle relative to the body. The apparatus may be used to first deliver a leading bleb of fluid to the subretinal space in a patient's eye via the needle. The apparatus may then be used to deliver a therapeutic agent to the subretinal space in the patient's eye via the catheter.

Sub-retinal tangential needle catheter guide and introducer

The present invention is a Miniature Vein Enhancer that includes a Miniature Projection Head. The Miniature Projection Head may be operated in one of three modes, AFM, DBM, and RTM. The Miniature Projection Head of the present invention projects an image of the veins of a patient, which aids the practitioner in pinpointing a vein for an intravenous drip, blood test, and the like. The Miniature projection head may have a cavity for a power source or it may have a power source located in a body portion of the Miniature Vein Enhancer. The Miniature Vein Enhancer may be attached to one of several improved needle protectors, or the Miniature Vein Enhancer may be attached to a body similar to a flashlight for hand held use. The Miniature Vein Enhancer of the present invention may also be attached to a magnifying glass, a flat panel display, and the like.

Micro vein enhancer

The present invention is a Miniature Vein Enhancer, for use in imaging the subcutaneous veins of a target area of a patient by a practitioner. The miniature vein enhancer includes a Miniature Projection Head that is secured to a tourniquet, where the tourniquet may be mounted to the bicep of a patient. The Miniature Projection Head includes a housing, and apparatus that images subcutaneous veins of the target area, and projects the image(s) of the veins onto the target area to overlie the subcutaneous veins, which aids the practitioner in pinpointing a vein location for a venipuncture procedure such as an intravenous drip, blood test, and the like.

A sweat sampling and sensing device for sensing sweat on skin includes an analyte-specific sensor for sensing a first analyte in sweat; a sweat collector placed on or adjacent to skin with a plurality of pores or pathways for entry of sweat from skin into said sweat collector, said sweat collector at least partly defining a sweat volume between said analyte-specific sensor and the skin; and a pressure element capable of holding said sweat collector against the skin with a pressure and reducing the sweat volume between said sweat collector and the skin.

Devices with reduced microfluidic volume between sensors and sweat glands

Vein imager with a dual buffer mode of operation

Embodiments of a reduced pressure system and methods for operating the system are disclosed. In some embodiments, the system can include one or more processors responsible for various functions associated with various levels of responsiveness, such as interfacing with a user, controlling a vacuum pump, providing network connectivity, etc. The system can present GUI screens for controlling and monitoring its operation. The system can determine and monitor flow of fluid in the system by utilizing one or more of the following: monitoring the speed of a pump motor, monitoring flow of fluid in a portion of a fluid flow path by using a calibrated fluid flow restrictor, and monitoring one or more characteristics of the pressure pulses. The system can provide external connectivity for accomplishing various activities, such as location tracking of the system, compliance monitoring, tracking of operational data, remote selection and adjustment of therapy settings, etc.

Reduced pressure wound therapy control and data communication

The present invention is a Miniature Vein Enhancer, for use in imaging the subcutaneous veins of a target area of a patient by a practitioner. The miniature vein enhancer includes a Miniature Projection Head, a base, and apparatus for securing the base of the miniature vein enhancer to the practitioner. The Miniature Projection Head includes a housing, and apparatus that images subcutaneous veins of the target area, and projects the image of the veins onto the target area to overlie the subcutaneous veins, which aids the practitioner in pinpointing a vein for an intravenous drip, blood test, and the like. The housing and the base may contain a ball and socket or other mechanical arrangement so that the housing may be rotatable with respect to the base to adjustably direct an optical path of the imaging onto various regions of the patient.
