## Abstract

A system to deliver energy to treat a mobile calculus, the system can include a drill and a lateral energy emitter. The drill can be configured to drill a recess into the mobile calculus or a passage through the mobile calculus. The lateral energy emitter can be configured to be advanced into the recess or the passage and to transmit the energy internal to the mobile calculus to fragment the mobile calculus. In some examples, the system can include a deployable capture portion to constrain a stone relative to the capture portion.

## Claims

### Claim 1

A system to deliver energy to treat a mobile calculus, the system comprising:
a drill configured to drill a recess into the mobile calculus or a passage through the mobile calculus; and
a transducer configured to be advanced into the recess or the passage and to transmit the energy internal to the mobile calculus to fragment the mobile calculus
wherein at least a portion of the drill is located at a distal end portion of a delivery member having an elongate shaft that is deliverable to a treatment site through a working channel, and wherein the transducer and the drill are coupled to the elongate shaft with the transducer located proximal of the drill.

### Claim 2 (depends on 1)

The system of claim 1, wherein the transducer includes an acoustic transducer.

### Claim 3 (depends on 1)

The system of claim 1, comprising a capture portion configured to constrain movement of at least a portion of the mobile calculus relative to the capture portion.

### Claim 4 (depends on 3)

The system of claim 3, wherein the capture portion is configured to capture at least a portion of the fragmented mobile calculus to be removed.

### Claim 5 (depends on 3)

The system of claim 3, wherein the capture portion is located at a distal end portion of the elongate shaft, and wherein the capture portion is configured to be advanced through the working channel and to be deployed distal of the mobile calculus.

### Claim 6 (depends on 3)

The system of claim 3, wherein the capture portion includes a deformable strut configured to expand into a deployed position.

### Claim 7 (depends on 3)

The system of claim 3, wherein the capture portion includes a receiving opening configured to receive the mobile calculus.

### Claim 8 (depends on 3)

The system of claim 3, wherein the capture portion includes a receiving opening and a closure member, and wherein the capture portion is deployable from a compressed state when positioned in the working channel to a receiving state when deployed distally from the working channel, and wherein in the receiving state the capture portion is configured to receive the mobile calculus through the receiving opening, and wherein when the closure member is actuated, the receiving opening deforms to enable the capture portion to constrain the mobile calculus in a captured state.

### Claim 9 (depends on 1)

The system of claim 1, wherein:
the delivery member having the elongate shaft includes a tubular structure including a surface and a fluid delivery channel extending therethrough, the fluid delivery channel in fluid communication with a fluid port in the surface, wherein the fluid port is configured to provide fluid into the recess or the passage to deteriorate the mobile calculus, and wherein the drill and the transducer are coupled to the elongate shaft.

### Claim 10 (depends on 9)

The system of claim 9, wherein the fluid port includes a plurality of fluid ports that are longitudinally spaced apart along a length of the elongate shaft.

### Claim 11 (depends on 9)

The system of claim 9, wherein the fluid port includes a plurality of fluid ports that are radially spaced apart around the elongate shaft.

### Claim 12 (depends on 1)

The system of claim 1, further comprising:
a delivery member having an elongate shaft including a tubular structure and a fluid delivery channel extending therethrough, wherein the drill is located at a distal end of the elongate shaft, and wherein the drill comprises a fluid port that is in fluid communication with the fluid delivery channel, the fluid port configured to supply a fluid to drill the recess or the passage in the mobile calculus.

### Claim 13

A method to treat a mobile calculus in a patient, the method comprising:
drilling a hole in the mobile calculus with a drill to create a recess into the mobile calculus or a passage through the mobile calculus, the drill coupled to a distal end portion of an elongate shaft that is deliverable to a treatment site through a working channel;
advancing an acoustic transducer into the recess or the passage, the acoustic transducer being coupled to the elongate shaft proximal of the drill; and
exciting the acoustic transducer to transmit acoustic energy to the mobile calculus to fragment the mobile calculus.

### Claim 14 (depends on 13)

The method of claim 13, further comprising:
deploying a capture portion configured to receive and constrain at least a portion of the mobile calculus.

### Claim 15 (depends on 13)

The method of claim 13, further comprising:
deploying a capture portion including a receiving opening;
receiving the mobile calculus into the receiving opening to capture the mobile calculus;
constraining movement of the mobile calculus relative to the acoustic transducer; and
exciting the acoustic transducer.

### Claim 16 (depends on 13)

The method of claim 13, further comprising:
capturing at least portion of the fragmented mobile calculus and removing the mobile calculus from the patient.

### Claim 17 (depends on 13)

The method of claim 13, further comprising:
suctioning a region around at least a portion of the fragmented mobile calculus to move at least a portion of the fragmented mobile calculus into a working channel.

### Claim 18 (depends on 13)

The method of claim 13, further comprising:
providing fluid through a delivery member having a tubular structure including a surface and a fluid delivery channel extending therethrough, the fluid delivery channel in fluid communication with a fluid port in the surface, wherein providing the fluid causes the fluid to be dispensed from the fluid port into the recess or the passage to cause deterioration of the mobile calculus.

### Claim 19

A system to deliver energy to treat a mobile calculus, the system comprising:
a drill configured to drill a recess into the mobile calculus or a passage through the mobile calculus; and
an energy emitter configured to be advanced into the recess or the passage and to transmit energy internal to the mobile calculus to fragment the mobile calculus
wherein at least a portion of the drill is located at a distal end portion of a delivery member having an elongate shaft that is deliverable to a treatment site through a working channel, and wherein the energy emitter and the drill are coupled to the elongate shaft with the energy emitter located proximal of the drill.
