Abstract
A trans-xiphoid procedure for gaining entry to the chest cavity of a patient, sometimes also referred to herein as a “TRAX” procedure. The procedure may be used for, among other things, mobilization of the mammary arteries and performing coronary artery bypass surgery in which the mammary artery of the patient or other conduit is joined to a coronary artery of the patient, such as the left anterior descending (LAD) coronary artery.
Claims18
A suction device useful for separating the mammary arteries of a subject from the internal chest wall of the subject, comprising:
- an elongate shaft having a proximal end and a distal end configured for placement internally in a subject during use;
- a handle on the shaft proximal end;
- an aspiration fitting on the shaft proximal end;
- and
- a suction fitting on the shaft distal end, the suction fitting having a outwardly or convexly curved top surface portion and an inwardly or concavely curved bottom surface portion, an end terminal portion, and at least one distal suction opening in the end terminal portion, the suction opening in fluid communication with the aspiration fitting through the shaft.
A suture retention device, comprising:
- a body having a top portion, a bottom portion, a width dimension, and a transverse channel formed in the top portion, the transverse channel extending the entire width dimension of the body;
- an adhesive member connected to the body bottom portion, with the channel extending therethrough;
- a suture retainer connected to the body and positioned within the transverse channel.
A mammary artery dissecting device, comprising:
- (a) an elongate shaft having a proximal end, a distal end, and a central opening formed therein, sand central opening configured to removably receive an endoscope for visualizing a mammary artery during dissection thereof;
- (b) a dissection tip connected to the distal end, the dissection tip including a transparent portion configured to form a visualization window therein through which a mammary artery may be visualized with an endoscope in the central opening;
- (c) at least one elongate cutting instrument and/or elongate cauterizing instrument axially aligned with and slideably connected to the elongate shaft, each instrument configured for slideably advancing the instrument out of the proximal end to facilitate cutting and/or cauterizing of tissues or vessels during dissection of a mammary artery, and then slideably retracting the instrument back into the proximal end when cauterizing or cutting is completed.
