Electrode Including A Multi-Region Current Collector
US Patent:
7740980, Jun 22, 2010
Filed:
Apr 24, 2006
Appl. No.:
11/379976
Inventors:
John M. Gray - Brooklyn Park MN, US

International Classification:
H01M 4/00
US Classification:
429128, 429163, 429209, 429233
Abstract:
An electrochemical cell is provided that includes a current collector plate and a pellet. The current collector plate includes a circumferential outer peripheral wall and an inner wall coupled thereto, where the circumferential outer peripheral wall defines a cavity and has a height, and the inner wall extends across and physically separates the cavity into at least two regions and has a height that is less than the height of the circumferential outer peripheral wall. The pellet comprises active powder material and is disposed in the cavity and circumferentially surrounded by and in contact with the circumferential outer peripheral wall of the current collector plate. The pellet includes a first portion and second portion, where the first portion is disposed in a first region of the at least two regions and the second portion is disposed in a second region of the at least two regions.

Implantable Infusion Device Including Anti-Sealing Reservoir
US Patent:
2013009, Apr 18, 2013
Filed:
Oct 18, 2011
Appl. No.:
13/275690

Assignee:
MEDTRONIC INC. - Minneapolis MN
International Classification:
A61M 5/142
US Classification:
6048911, 6048901
Abstract:
Techniques are disclosed for reducing the accumulation of gases in an implantable infusion device. In one example, an implantable infusion device (IID) includes a housing, an expandable and contractible reservoir, and a standoff member. The expandable and contractible reservoir is configured to store a therapeutic agent and is arranged within the housing. A first end of the reservoir is configured to collapse toward a second end of the reservoir as the reservoir contracts. The standoff member is interposed between the first end and the second end of the reservoir and is configured to hold at least a portion of the first end offset from the second end when the reservoir is in a contracted state.

International Classification:
A61K 9/22
US Classification:
6048911, 604131, 604151, 604152
Abstract:
An accumulator is employed in an implantable infusion device to provide compliance in the flow path of the device. The accumulator may act to increase the pumping accuracy and repeatability while simultaneously reducing the energy requirements of the device. In one example, the accumulator is arranged at the outlet of a fluid delivery pump of the infusion device. The accumulator includes a cover and a diaphragm biased away from the cover and configured to deflect toward the cover under pressure generated by the therapeutic agent in a flow path of the infusion device. The cover of the accumulator is configured to withstand the pressure generated by the therapeutic agent in the flow path without deforming.

Dale A. Young - Lake Elmo MN, US
Assignee:
Medtronic, Inc. - Minneapolis MN
International Classification:
A61M 5/168
US Classification:
6048911
Abstract:
An implantable medical device is configured with a pressure sensor arranged within the device to reliably and accurately measure the pressure within a propellant gas chamber at least partially surrounding a therapeutic fluid reservoir of the device. In one example, a housing of the IMD includes a protrusion that is configured to provide clearance for fluid communication between a propellant gas chamber pressure sensor and the propellant gas chamber.

International Classification:
A61M 5/168
US Classification:
6048911, 604 67
Abstract:
A method comprises measuring a volume of fluid delivered per pump stroke for each of a plurality of substantially identical medical pumps. The substantially identical medical pumps each have a fixed stroke length. The method further comprises: storing indications of the measured volumes on one or more data storage mediums; and for each of the plurality of substantially identical medical pumps, generating a separate therapy control program based on the indication of the measured volume associated with that one of the plurality of substantially identical medical pumps.
