Abstract
Example medical devices are disclosed. An example medical device includes a handle having a distal end region, a proximal end region and an inner chamber. The medical device also includes a guidewire brake including an actuation member coupled to a first gripping member and a second gripping member. The first gripping member and a second gripping member are disposed within the inner chamber of the handle and at least a portion of the actuation member is positioned along an outer surface of the handle. Further, the first gripping member and the second gripping member are configured to shift between an unclamped configuration and a clamped configuration.
Claims17
A medical device, comprising:
- a handle having a distal end region, a proximal end region and an inner chamber;
- a guidewire brake including an actuation member coupled to a first gripping member and a second gripping member;
- and
- a sensor attached to the guidewire brake;
- wherein the first gripping member and the second gripping member are disposed within the inner chamber of the handle;
- wherein at least a portion of the actuation member is positioned along an outer surface of the handle;
- wherein the first gripping member is coupled to the actuation member by a first pivotal linkage and the second gripping member is coupled to the actuation member via a second pivotal linkage different from the first pivotal linkage;
- wherein the first gripping member and the second gripping member are configured to shift between an unclamped configuration and a clamped configuration.
An atherectomy device, comprising:
- a handle having a distal end region, a proximal end region and an inner chamber;
- a drive shaft coupled to the distal end region of the handle, the drive shaft including an atherectomy burr disposed along a distal end of the drive shaft;
- and
- a guidewire brake including an actuation member coupled to a first gripping member and a second gripping member;
- and
- a sensor attached to the guidewire brake;
- wherein the first gripping member and the second gripping member are disposed within the inner chamber of the handle;
- wherein the first gripping member is coupled to the actuation member by a first pivotal linkage and the second gripping member is coupled to the actuation member via a second pivotal linkage different from the first pivotal linkage;
- wherein at least a portion of the actuation member is positioned along an outer surface of the handle;
- wherein the first gripping member and the second gripping member are configured to shift between an unclamped configuration and a clamped configuration.
A method of treating a tissue lesion, the method comprising:
- advancing an atherectomy device over a guidewire to a lesion, the atherectomy device including:
- a handle having a distal end region, a proximal end region and an inner chamber;
- a drive shaft coupled to the distal end of the handle;
- an atherectomy burr coupled to the distal end of the drive shaft;
- a guidewire brake including an actuation member coupled to a first gripping member and a second gripping member, wherein the first gripping member and the second gripping member are disposed within the inner chamber of the handle, wherein the first gripping member is coupled to the actuation member by a first pivotal linkage and the second gripping member is coupled to the actuation member via a second pivotal linkage different from the first pivotal linkage, and wherein at least a portion of the actuation member is positioned along an outer surface of the handle;
- and
- a sensor attached to the guidewire brake;
- actuating the actuation member such that the first and second gripping members clamp the guidewire therebetween;
- and
- rotating the atherectomy burr.
