Filed:

Sep 24, 2003

Appl. No.:

10/671191

Inventors:

Daniel R. Burnett - San Francisco CA, US

Assignee:

Medventure Associates IV - Emeryville CA

International Classification:

A61B 19/00
A61M 29/00

US Classification:

128898, 606192

Abstract:

Pyloric valve corking devices and methods are described herein. The devices generally include an occluding member which expands from a first configuration to a larger second configuration and a bridging member extending from the occluding member. The bridging member has a length which passes at least partially through the gastric opening such that the occluding member obstructs the gastric opening, and wherein the length permits the occluding member to intermittently move relative to the gastric opening. A second occluding member may be attached to the distal end of the bridging member. The reduction in flow of gastric contents into the duodenum can be tightly regulated using a pump or valve. Otherwise, the flow can be passively regulated with the occluding device.

US Classification:

604 9, 604 8, 60416401, 604517

Abstract:

An implantable fluid management device, designed to drain excess fluid from a variety of locations in a living host into a second location within the host, such as the bladder of that host. The device may be used to treat ascites, chronic pericardial effusions, normopressure hydrocephalus, hydrocephalus, pulmonary edema, or any fluid collection within the body of a human, or a non-human mammal.

International Classification:

A61F 2/06

US Classification:

623 111, 606198

Abstract:

Apparatus for delivering a medical device to a location in a patient's body includes an elongate catheter body having a proximal end and a distal end, a pod coupled with the distal end of the catheter body and adapted to house the medical device during delivery to the location and to open to release the medical device, and at least one distal actuator coupled with at least one of the pod and the medical device. The distal actuator is adapted to promote opening of the pod. A method involves advancing a pod at the distal end of an elongate catheter to the location within the body and activating an actuator coupled with the pod and/or the medical device to cause the pod to open. Opening the pod releases the medical device.

Appl. No.:

11/332799

Inventors:

Daniel Rogers Burnett - San Francisco CA, US
Shane Mangrum - Ammon ID, US

Assignee:

TheraNova, LLC - San Francisco CA

International Classification:

A61M 11/00

US Classification:

12820418

Abstract:

The present invention may create and maintain a pressure differential in the vicinity of the user's nasopharynx. A portable filter and pressurized air source subjects the region of the user's nasopharynx to positive or negative pressured air. Positive pressure prevents exposure to surrounding air while negative pressure isolates those around the user from potential toxins or pathogens exhaled from the user. With positive pressure, surrounding air is displaced preventing exposure to ambient air in most instances. With negative pressure, exhaled air is evacuated from the nasopharynx, filtered and returned to the user's surroundings to prevent exposure to those around the user. Such devices may be incorporated into garments, accessories or existing isolation devices (e. g. , face masks) to improve efficacy. Alternatively, the device may also be attached to an air source in the user's vicinity and provide filtration of the air prior to delivery to the region surrounding the user.

11/373523

Inventors:

International Classification:

A61B 5/145

US Classification:

600319, 600309, 600316, 600365

Abstract:

A method for determining the quantity of an analyte in a fluid is described along with various components of an apparatus designed to carry out the method. The method involves habituating a patient's eye to one or more colors, measuring the recovery time, and correlating the recovery time to the quantity of the analyte. A reproducible, objective, non-attentiveness-dependant test for assessing analyte levels is further disclosed. To this end, a device that measures saccadic eye movements may be used to assess the return of vision to the prehabituated state. The method and apparatus are particularly suited for noninvasively measuring blood glucose levels.
