US Patent:

6508756, Jan 21, 2003

Filed:

Dec 30, 1998

Appl. No.:

09/223645

Inventors:

Robert T. V. Kung - Auburn MA
David M. Lederman - Marblehead MA
Meir Rosenberg - Newton MA

Assignee:

Abiomed, Inc. - Danvers MA

International Classification:

A61F 202

US Classification:

600 37

Abstract:

Artificial implantable active and passive girdles include a heart assist system with an artificial myocardium employing a number of flexible, non-distensible tubes with the walls along their long axes connected in series to form a cuff and a passive girdle is wrapped around a heart muscle which has dilatation of a ventricle to conform to the size and shape of the heart and to constrain the dilatation during diastole. The passive girdle is formed of a material and structure that does not expand away from the heart but may, over an extended period of time be decreased in size as dilatation decreases.

International Classification:

A61B 800

US Classification:

600437

Abstract:

An acoustic monitoring system that is able to verify the success or failure of the positional adjustment of a valve without the need for additional energy during non-invasive reprogramming is provided. The acoustic monitoring system includes a programmer for generating a sequence of commands to adjust the valve mechanism, and for receiving acoustic signals for analysis, a transmitter to implement the command and adjust the valve, and a sensor for detecting an acoustic signal generated from the valve during execution of the commands. A method for using the acoustic monitoring system is also provided.

Appl. No.:

10/056285

Inventors:

Meir Rosenberg - Newton MA, US

Assignee:

Codman & Shurtleff, Inc. - Raynham MA

International Classification:

A61M005/00

US Classification:

604 9, 604 8

Abstract:

An anti-siphon shunt device is provided that is insensitive to body postural changes. The shunt device has a housing having a chamber, an inlet port, and an outlet port. A valve mechanism disposed within the housing manages fluid movement into and out of the chamber over a pressure gradient. The valve mechanism includes a blocking element configured to seat against an opening in a barrier mounted within the chamber for preventing fluid flow therethrough. A pressure sensor having a conformable membrane detects the external pressure surrounding the chamber and communicates with a biasing element to exert a biasing force against a first surface of the blocking element, while a second surface of the blocking element is acted upon by a countervailing pressure in a direction opposite the biasing force. The conformable membrane can be enclosed within a housing to protect the device from shutting off when a patient inadvertently lies on the valve mechanism.

Assignee:

Codman & Shurtleff, Inc. - Raynham MA

International Classification:

A61M 5/00

US Classification:

604 8, 604 7, 604264

Abstract:

An implantable fluid management device includes a catheter with an elongate proximal portion, a flexible distal portion, and a fluid passageway flowing therethrough. The distal portion includes a coil-shaped portion that defines a spiral having at least one turn. The distal portion of the catheter includes at least one pore in fluid communication with the fluid passageway of the catheter, which is located on an internal portion of the spiral. The positioning of the pore(s) on the internal portion of the spiral protects the pore(s) from obstruction or occlusion caused by tissue growing into or around the catheter.

US Classification:

604 9, 604 8, 604264

Abstract:

A self adjusting hydrocephalus valve that continuously drains cerebrospinal fluid at a rate which is proportional to the average pressure difference across the valve. The valve employs a ball-in-cone mechanism having an associated biasing element that is insensitive to high frequency pressure variations for regulating the opening of the valve mechanism. The biasing element includes flexible bellows having a preset tension.

Assignee:

Codman & Shurtleff, Inc. - Raynham MA

International Classification:

A61K 9/22

US Classification:

6048911

Abstract:

A valve that is adapted to control the flow rate of fluid flow from an implantable pump or other fluid delivery device is provided. In general, the valve includes a multi-lumen member that is adapted to receive fluid-flow therethrough, and a restrictor member that is coupled to the multi-lumen member such that the restrictor member is effective to selectively restrict at least a portion of one or more lumens in the multi-lumen member to thereby adjust the flow rate of fluid flowing through the multi-lumen member. The valve can be built into an implantable drug pump to control fluid flow exiting the pump, or alternatively the valve can disposed within a catheter or otherwise coupled to an outlet port in an implantable drug pump to control the flow rate of fluid exiting the drug pump.
