US Patent:

20110276147, Nov 10, 2011

Filed:

Jul 20, 2011

Appl. No.:

13/187340

Inventors:

Russell Cook - Costa Mesa CA, US
Duraid Antone - Aliso Viejo CA, US

Assignee:

NUVASIVE, INC. - San Diego CA

International Classification:

A61F 2/28
A61B 19/00

US Classification:

623 2351, 206438

Abstract:

An osteoinductive bone graft substitute composition that does not return to its original shape upon hydration or manipulation is disclosed, comprising, in combination, about 86-89% by weight of a calcium phosphate particulate mineral component and about 11-14% by weight of a purified fibrillar collagen, the mineral component including about 20% to about 60% by weight of hydroxyapatite and about 60% to about 20% by weight of tricalcium phosphate. A package configured to store a bone graft composition is disclosed, comprising an inner sterile polymeric V-shaped pouch located in an outer sterile polymeric V-shaped pouch. Methods for repairing a bone defect in a patient are disclosed using the osteoinductive bone graft substitute composition.

Appl. No.:

17/746200

Inventors:

- IRVINE CA, US
Russell Cook - Irvine CA, US

International Classification:

H02H 7/18
B60R 16/033
H02H 3/24

Abstract:

A disclosed under-voltage lockout (UVLO) circuit includes an automatic UVLO threshold configuration. The UVLO circuit may include an over-voltage protection circuit that receives power from a power source, a peak detector that detects a peak voltage output for the power source, a voltage threshold generator that sets a UVLO threshold based on the peak voltage output, and a comparator that compares an instantaneous voltage with the UVLO threshold and configures an operating mode of a device based on the comparison.

Abstract:

Embodiments of the invention include an under-voltage lockout (UVLO) circuit with automatic UVLO threshold configuration. In an embodiment, the UVLO circuit includes an over-voltage protection circuit that receives power from a power source, a peak detector that detects a peak voltage output for the external power source, a voltage threshold generator that sets a UVLO threshold based on the peak voltage output, and a comparator that compares an instantaneous voltage with the UVLO threshold and configures an operating mode of a device based on the comparison.
