Apparatus and methods for ablating material in a region within a vascular system of a patient are provided. A determination of at least one of a type of material in the region and an indication of a distance to the material in the region is made based on at least one property of the region determined from light reflected from the region. Light from a light source is transmitted in at least one of a plurality of optical fibers based on the determination, and at least some of the transmitted light is received at a first emitter disposed along a length of a laser catheter proximate a distal end thereof. The first emitter radially transmits the at least some of the light from the length of the laser catheter so that the light impinges upon and ablates the material through an opening in the length of the laser catheter.

Apparatus and methods for determining a type of a material in a region within a vascular system of a patient are provided. The determination is made after light has been reflected from the region after being supplied to the region from a light source by at least one optical fiber. The determination is made based on an analysis of the light reflected from the region and of a received at least one indication of a force applied to the material in the region by one or more of the at least one optical fiber. The indication of the force applied by the one or more of the at least one optical fiber is provided by at least one force sensor coupled to the at least one optical fiber.

An article of handwear for grasping a medical device in a medical environment includes a base adapted to be worn by a hand of a wearer. A sensor assembly is carried by the base. The sensor assembly is adapted to sense a force applied by the hand of the wearer, via the article of handwear, to the medical device. The sensor assembly is adapted to provide information regarding at least one shear component of the forces sensed by the sensor assembly.
