AI Technical Summary

Problems solved by technology

In some systems, the size of the annuloplasty catheter interferes with its visualization, compromising accuracy and increasing inadvertent contact with and associated damage to cardiac features
Positioning of annuloplasty catheters can be especially challenging in patients with pacemaker and defibrillator leads

Embodiment Construction

[0029] According to one aspect, a minimally invasive intraluminal annuloplasty system and method of use are provided, the system including a guide catheter configured to guide a working catheter to a treatment site within a heart chamber. Due to this arrangement, the likelihood of accidental contact and associated cardiac injury is reduced through controlled advancement and accurate placement of the working catheter during annuloplasty.

[0030] In one embodiment, a guide catheter may be translatably disposed within a working catheter, which in turn may be translatably disposed within an introducer sheath extending into a heart chamber. The guide catheter can be configured to facilitate visualization of its distal end. For example, the guide catheter may be sized to reduce noise and / or may be constructed of a material that facilitates visualization. In one embodiment, the guide catheter includes a distal guidewire anchor. Visualization can be used to embed the distal guidewi...

Abstract

The invention provides a minimally invasive endoluminal annuloplasty system and method of use. The system includes a guide catheter configured to guide a working catheter to a treatment site inside a cardiac cavity. The guide catheter may be translatably disposed inside a working catheter, which may be translatably disposed inside an introducer sheath extending into the heart cavity. The guide catheter may be sized to reduce noise and / or may be comprised of a material that facilitates visualization. In one embodiment, a guide catheter includes a distal guidewire anchor. The visualization may be used to embed the distal guidewire anchor in tissue at the target site.

Description

technical field [0001] The present disclosure relates generally to the field of medical devices, and more particularly to an annuloplasty system and method of use. Background technique [0002] The tricuspid valve is located between the right atrium and right ventricle of the heart, and its function is to prevent the backflow of blood from the right ventricle into the right atrium. The tricuspid valve is made up of three leaflets: anterior, posterior, and septal. The leaflets are connected to the anterior, posterior, and septal papillary muscles of the right ventricle, respectively, via the chordae. [0003] In a healthy heart, the tricuspid valve acts as a one-way valve membrane, a pilot valve that closes during ventricular systole to prevent tricuspid regurgitant (TR) blood from entering the right atrium. In a diseased heart, dilation of the tricuspid valve during systole can cause the valve to no longer close or coagulate effectively. Thus, regurgitation of blood occur...
