Abstract
The present invention relates to apparatuses for cutting and removing occlusive material with imaging capabilities. According to certain aspects, the apparatus includes a catheter body, a rotatable shaft, and an imaging element. The catheter body defines a lumen and includes a distal housing that defines an opening. The rotatable shaft is disposed within the lumen of the catheter body. The rotatable shaft includes a conveying component and a cutting element that is at least partially surrounded by the distal housing. The imaging element is located on the distal housing of the catheter body.
Claims26
An apparatus for cutting and removing occlusive material, the apparatus comprising:
- a catheter body defining a first lumen and comprising a distal housing that defines an opening;
- a rotatable shaft disposed within the first lumen of the catheter body, wherein the rotatable shaft comprises a conveying component and a cutting element that is at least partially surrounded by the distal housing;
- and
- an imaging element located on the distal housing.
An apparatus for cutting and removing occlusive material, the apparatus comprising:
- a catheter body defining a first lumen and comprising a distal end;
- a rotatable shaft disposed within the first lumen of the catheter body and comprising a conveying component along the length of the rotatable shaft;
- a cutting element operably coupled to the rotatable shaft;
- and
- a housing coupled to the distal end of the catheter body, the housing defines a distal opening, at least partially surrounds the cutting member, and comprises an imaging element.
An apparatus for cutting and removing occlusive material, the apparatus comprising:
- a catheter body defining a first lumen and comprising a distal end;
- a rotatable shaft disposed within the first lumen of the catheter body and comprising a conveying component along the length of the rotatable shaft;
- a cutting element operably coupled to the rotatable shaft, wherein the cutting element comprises at least one blade element with a positive rake angle and at least one crushing element with a negative rake angle;
- and
- a housing coupled to the distal end of the catheter body, the housing defining a distal opening and at least partially surrounding the cutting member.
