Tissue cutting device
First Claim
1. A tissue cutting device, comprising:
- a probe defining a probe axis; and
a cutting assembly configured to be in one of a storage configuration and a cutting configuration including;
a first cutting blade having a first inner surface, a first cutting edge, and a first set of cutting teeth disposed along at least a portion of the first cutting edge; and
a second cutting blade having a second inner surface, a second cutting edge, and a second set of cutting teeth disposed along at least a portion of the second cutting edge, the cutting assembly being configured with the first inner surface being in contact with and in close apposition with the second inner surface so that the first set of cutting teeth is aligned with and configured to cooperate with the second set of cutting teeth when at least one of the first and second cutting blades moves relative to the other when the cutting assembly is in the cutting configuration.

Abstract
Devices for efficient severing or cutting of a material or substance such as soft tissue suitable for use in open surgical and/or minimally invasive procedures are disclosed. A cutting assembly generally includes a first and second cutting blades each having an inner surface and at least one set of cutting teeth, the first inner surface being in contact with the second inner surface so that the sets of cutting teeth of the first and second cutting blades are aligned with and configured to cooperate with each other when at least one of the cutting blades moves, e.g., rotates and/or oscillates, relative to the other. A tissue cutting device generally includes a probe and the cutting assembly configured to be in a storage configuration or in a cutting configuration. The cutting assembly may provide a coagulation mechanism.

29. A method for cutting tissue, comprising:
-
positioning a distal region of a probe of a tissue cutting device adjacent to a region of tissue to be severed, the probe defining a probe axis;
returning a cutting assembly from a storage configuration to a cutting configuration;
moving at least one of a first cutting blade and a second cutting blade of the cutting assembly relative to the other, the moving being at least one of rotating and oscillating, the first cutting blade having a first inner surface, a first cutting edge, and a first set of cutting teeth disposed along at least a portion of the first cutting edge, the second cutting blade having a second inner surface, a second cutting edge, and a second set of cutting teeth disposed along at least a portion of the second cutting edge, the first inner surface being in contact and in close apposition with the second inner surface so that the first set of cutting teeth is aligned with and configured to cooperate with the second set of cutting teeth when at least one of the first and second cutting blades moves relative to the other; and
one of advancing and retracting the tissue cutting device during the moving of the cutting blades such that the cutting assembly severs the tissue. - View Dependent Claims (30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53)
