Filed:

Mar 30, 2001

Appl. No.:

09/822678

Inventors:

Mahmoud K. Seraj - Apex NC
Eric Chan - Newark CA
James F. Kelley - Coon Rapids MN

Assignee:

Medtronic, Inc. - Minneapolis MN

International Classification:

A61B 1818

US Classification:

606 41, 607122, 60416413

Abstract:

This is a combination method and system for intravascularly accessing and visualizing a body structure. A system is disclosed comprising a sheath, a balloon catheter, and a catheter deflection mechanism. A micro-deflection mechanism, which may be placed into the lumen of devices such as cardiac leads or electrophysiology catheters, is also provided for accurate guidance and placement of such devices to their target location. In one embodiment, a procedure for a lead or catheter placement is described in which a combination deflection mechanism, balloon catheter, and sheath assembly access the coronary sinus ostium via a superior approach. A distal balloon on the catheter is inflated and an occlusive venogram is obtained under fluoroscopic guidance to visualize the coronary veins. The sheath is advanced into the coronary sinus ostium and the balloon is deflated. The catheter and deflection mechanism are then removed.

International Classification:

A61B 1818

US Classification:

606 41, 604 9504

Abstract:

An intravascular electrophysiology (EP) device for the mapping and/or formation of lesions along the isthmus region of a heart that has particular utility in the treatment of atrial flutter. The EP device of the invention has an elongated shaft with a proximal section, a compound-curved or modified pigtail-shaped distal section, and a plurality of at least partially exposed electrodes disposed on an outer surface of the distal section. The electrodes are spaced along a length of the distal section and may be interspersed with at least one temperature sensor located between electrodes. The shape of the distal end of the device enables manipulation of the device by inserting its distal end in the tricuspid valve and retracting the device to bias the section having electrodes along the isthmus to achieve acceptable contact with the region so high frequency (e. g. , RF) electrical energy delivered to the electrodes on the distal section of the EP device will form a lesion. Sections of the isthmus where treatment is desired but not reached by the section of the device biased against tissue by retraction may be ablated by repeating the steps of hooking the tricuspid valve at a different end location of the device and retracting to bias the electrodes against different tissue, simply advancing the section with electrodes to the desired site or retracting the device so a tip connected to an RF source will drop into a desired site where ablation may occur.

International Classification:

H01B 7/00

US Classification:

174 69, 174 731, 174 93

Abstract:

The resilient sleeve member defines an axially extending inner passage. The holdout device includes a core mounted in the inner passage of the sleeve member. The core defines a core passage to receive the elongate substrate and has at least first and second sections. The first and second sections are arranged in a supporting position such that the core maintains the sleeve member in a radially expanded condition. The first and second sections are arranged for relative telescoping movement from the supporting position to a releasing position to permit at least a portion of the sleeve member to radially contract from the radially expanded position to a radially recovered position.

Abstract:

An enclosed connection system for connecting first and second elongate electrical conductors includes a transverse wedge connector and an enclosure. The transverse wedge connector includes an electrically conductive first connector member, an electrically conductive second connector member, and a clamping mechanism. The first connector member includes: a first body having inner and outer opposed ends; a first hook portion on the outer end of the first body, the first hook portion defining a first channel to receive the first conductor; and a first abutment portion on the inner end of the first body. The second connector member includes: a second body having inner and outer opposed ends; a second hook portion on the outer end of the second body, the second hook portion defining a second channel to receive the second conductor; and a second abutment portion on the inner end of the second body. The clamping mechanism is selectively operable to displace the first and second connector members relative to one another from an open position to a clamping position to clamp the first conductor in the first channel and between the first hook portion and the second abutment portion and to clamp the second conductor in the second channel and between the second hook portion and the first abutment portion to thereby form a connection. The enclosure is configured to receive and cover the connection and to protect the transverse wedge connector.

174 88R

Abstract:

A method for forming a connection assembly includes: forming an electrical connection between first and second electrical cables, the first cable including a first primary conductor and a first neutral conductor, the second cable including a second primary conductor and a second neutral conductor; and providing an integral, unitary cover assembly. The cover assembly includes: an inner elastomeric sleeve defining a cable passage to receive the electrical connection and the first and second primary conductors; and an outer elastomeric sleeve surrounding the inner sleeve. The method further includes: mounting the cover assembly on the cables such that the electrical connection and the first and second primary conductors extend through the cable passage; installing a first protective sleeve on a first neutral segment of the first neutral conductor; routing the first neutral segment and the first protective sleeve exteriorly of the outer sleeve to a second neutral segment of the second neutral conductor; and mechanically and electrically coupling the first and second neutral segments to thereby provide electrical continuity between the first neutral conductor and the second neutral conductor.
