Assignee:

Scimed Life Systems, Inc. - Maple Grove MN

International Classification:

A61B 1720

US Classification:

604 22, 606 41, 607113

Abstract:

A catheter having an elongate shaft including a proximal and a distal end. The shaft includes a conductor. An electrode is disposed at the distal end of the shaft and is connected to the conductor. The electrode has a generally annular, cross-sectional shape. The annular shape defines an opening within the electrode. An insulator surrounds the conductor. In accordance with the method of the present invention, a crater wound can be formed through the endocardium and into the myocardium of a patients heart. Collateral damage to the myocardium can be made by infusing pressurized fluid into the crater wound.

International Classification:

A61B 18/14

US Classification:

606 41

Abstract:

Medical devices and methods for making and using medical devices are disclosed. An example medical device may be a deflectable medical device that includes a catheter shaft having a distal end. An ablation electrode may be disposed at the distal end. A deflection mechanism may be coupled to the catheter shaft. The deflection mechanism may include a deflection body and a pull wire coupled to the deflection body. The deflection body may have a longitudinally-extending furrow formed therein. A flex member may be disposed adjacent to the deflection mechanism.

Appl. No.:

9/271045

Inventors:

Louis Ellis - St. Anthony MN
Gary L. Hendrickson - Big Lake MN

International Classification:

A61B 1732

US Classification:

606167

Abstract:

A transmyocardial revascularization catheter which includes an elongate drive shaft having a proximal end, a distal end and a longitudinal axis. The TMR catheter also includes a cutting tip disposed at the distal end of the shaft. The tip has a distally disposed cutting edge and a longitudinally extending lumen therethrough. A motor is coupled to the drive shaft for rotation of the cutting tip. The shaft defines a longitudinally extending lumen in fluid communication with the tip lumen.

International Classification:

A61B 1732

US Classification:

606167

Abstract:

Devices and methods for increasing blood perfusion within the myocardium of the heart by wounding the myocardium and applying growth factors to promote vascularization. One method includes driving spikes into the myocardium from within the heart, with the spikes being formed of biodegradable material, containing releasable growth factors, and having lumens and side holes. An alternative method utilizes non-biodegradable spikes with lumens and side holes. Another method promotes vascularization by injecting angiogenic material into holes bored into the myocardium, leaving a patent hole. Another method includes injecting angiogenic material into the myocardium without boring, leaving no patent hole. The angiogenic material can be carried in a biodegradable adhesive. Revascularization of the myocardium is promoted in one method by externally wounding the heart and applying a patch including growth factors.
