US Patent:

7891086, Feb 22, 2011

Filed:

Feb 4, 2008

Appl. No.:

12/025358

Inventors:

Edgardo Ortiz Negron - Bayamon PR, US
Victor Torres Serrano - Guaynabo PR, US

Assignee:

Cardiac Pacemakers, Inc. - St. Paul MN

International Classification:

H01R 43/00

US Classification:

29825, 29868, 2541343 R

Abstract:

A method for stringing a first elongate element through a second elongate element is provided by placing the first elongate element in a channel and injecting compressed gas into the channel to propel the first elongate element therethrough. The channel has a first open end, and the second elongate element is sealed around the first open end. Compressed gas is injected into the channel towards the second elongate element, propelling the first elongate element through the second elongate element. Also disclosed is a system for performing such a method, including a source of compressed gas and a housing having a channel with a first end and a second open end. The first end is in fluid communication with the source of compressed gas. The channel has a tapered portion adjacent the open end of the channel, and the channel defines a straight longitudinal axis between the first end and the second open end.

International Classification:

Abstract:

A method for stringing a conductive element through a hollow sheath to assemble an electrical cable is provided by injecting compressed gas into the sheath to propel the conductive element therethrough. The conductive element is loaded into a closed channel in fluid communication with a source of compressed gas. A first end of the channel terminating in a needle is inserted into the sheath. The sheath is sealed around the needle and secured into position. Compressed gas, for example, air or nitrogen, is injected in pulses into the channel towards the sheath. The compressed gas radially expands the sheath and forms an air bearing on an inner surface of the sheath. The conductive element is propelled through the sheath over the air bearing. Upon removal of the pressurized gas, the sheath contracts to a normal position to secure the conductive element therein.
