7892276, Feb 22, 2011

Filed:

Dec 21, 2007

Appl. No.:

12/004561

Inventors:

Patrick J. Stocker - Ramsey MN, US
Joseph C. Walker - Shoreview MN, US

Assignee:

Boston Scientific Scimed, Inc. - Maple Grove MN

International Classification:

A61F 2/06

US Classification:

623 124, 623 217

Abstract:

A valve for use in a body lumen, where the valve includes a valve leaflet with delayed leaflet deployment relative an in vivo implant time. The valve includes a valve frame, a valve leaflet coupled to the valve frame. The valve leaflet includes a commissure that can reversibly seal for unidirectional flow of a liquid through the valve, and a biodegradable adhesive between the valve leaflet and the valve frame to hold at least the commissure of the valve leaflet in a static relationship relative the valve frame for a predetermined time once implanted in vivo.

International Classification:

H01R 24/04

US Classification:

439669, 439909

Abstract:

An IS-4 terminal connector assembly includes three terminal electrodes positioned over an inner tubular member such that they are radially offset from one another. Each of the terminal ring electrodes are configured such that they can withstand both tensile and cyclical bending loads with minimal compromise in their outer geometry. Additionally, each of the terminal electrodes is configured such that they have both an inner and outer geometry that facilitates adequate insulation between a select terminal electrode and an adjacent conductor. Additionally, each of the terminal ring electrodes is configured such that they facilitate an external approach to staking a cable conductor.

International Classification:

A61N 1/00
A61B 5/04

US Classification:

607 44, 607 2, 607116, 600381

Abstract:

Disclosed herein, among other things, is a system for electrical stimulation of blood vessels. An embodiment of the system includes at least one electrode having electrical contact with a blood vessel. The embodiment also includes a stimulation circuit electrically connected to the electrode, the circuit adapted to provide stimulation to the vessel. The embodiment further includes a controller connected to the circuit, the controller adapted to select frequency and voltage parameters for the stimulation circuit to selectively affect vascular therapy, including constriction of the vessel and dilation of the vessel. According to various embodiments, the stimulation circuit and controller are contained within an implantable medical device (IMD). The system also includes a sensor connected to the controller, and the controller initiates and adjusts therapy based on a signal received from the sensor, in varying embodiments.

Assignee:

Cardiac Pacemakers, Inc. - St. Paul MN

International Classification:

A61N 1/00

US Classification:

607122

Abstract:

An implantable lead having a distal assembly including a coupler, a fixation helix secured to the coupler, a housing in which the fixation helix and the coupler are disposed, and a resilient seal that is fixedly secured to the coupler between proximal and distal ends thereof and able to translate with the coupler relative to the housing. The seal is positioned to sealingly engage an internal surface of the housing. When the coupler is translated such that the fixation helix is in a fully extended position, the seal is positioned to substantially seal off the housing to prevent tissue ingrowth.

International Classification:

A61N 1/362

US Classification:

607 11, 607 9, 607 10

Abstract:

A method and device for treating myocardial ischemia in which an implantable pulse generator delivers electrical stimulation to electrodes disposed near a coronary artery. The stimulation parameters may be adjusted to produce vasodilation and/or vasoconstriction of the artery. The device may be configured to operate in a vasodilation and/or vasoconstriction mode in accordance with specified entry and exit conditions.
