a guide bundle that is in optical communication with the light source, the guide bundle bundling the first light guide and the second light guide, the guide bundle including a first ferrule that engages the guide proximal end of the first light guide and a second ferrule that engages the guide proximal end of the second light guide; and

a receptacle assembly including (i) a first receptacle hole that is configured to receive the first ferrule, and (ii) a second receptacle hole that is configured to receive the second ferrule;

wherein the receptacle assembly includes a retainer assembly including a clamping bar in direct contact with the first ferrule and the second ferrule such that the clamping bar applies a retaining force directly onto the first ferrule and the second ferrule so as to retain (i) the first ferrule in the first receptacle hole, and

(ii) the second ferrule in the second receptacle hole.

2 . The catheter system of claim 1 wherein the retainer assembly further includes a plunger that is configured to contact (i) at least a portion of the first ferrule so that the first ferrule is retained in the first receptacle hole, and (ii) at least a portion of the second ferrule so that the second ferrule is retained in the second receptacle hole.

3 . The catheter system of claim 2 wherein the plunger is a ball spring plunger.

4 . The catheter system of claim 2 wherein the plunger is integrated into the clamping bar.

5 . The catheter system of claim 1 wherein the receptacle assembly further includes a receptacle block and a backing plate that is coupled to the receptacle block, the backing plate being configured to engage the first ferrule and the second ferrule.

6 . The catheter system of claim 5 wherein the first receptacle hole and the second receptacle hole are formed as v-grooves in the receptacle block.

7 . The catheter system of claim 5 wherein the first receptacle hole and the second receptacle hole are each formed in the receptacle block, the first receptacle hole and the second receptacle hole being aligned on a same linear axis as one another.

8 . The catheter system of claim 5 wherein the backing plate includes (i) a first alignment hole that is configured to align a first guide beam with the first light guide, and (ii) a second alignment hole that is configured to align a second guide beam with the second light guide.

9 . The catheter system of claim 1 further comprising an alignment guide and an alignment guide receiver that are configured to engage one another to guide alignment between the first ferrule and the first receptacle hole and between the second ferrule and the second receptacle hole; wherein the alignment guide is coupled to one of the guide bundle and the receptacle assembly; and wherein the alignment guide receiver is coupled to the other of the guide bundle and the receptacle assembly.

10 . The catheter system of claim 1 wherein the guide bundle further includes (i) a first ferrule assembly including the first ferrule and a first spring that engages the first ferrule, the first spring being configured to provide an insertion force when the first ferrule is inserted into the first receptacle hole, and (ii) a second ferrule assembly including the second ferrule and a second spring that engages the second ferrule, the second spring being configured to provide an insertion force when the second ferrule is inserted into the second receptacle hole.

11 . The catheter system of claim 1 wherein the light source includes a laser, and wherein each of the first light guide and the second light guide includes an optical fiber.

12 . A catheter system for treating a treatment site within or adjacent to a vessel wall or a heart valve, the catheter system comprising:

a light source that generates light energy;

a first light guide that receives the light energy from the light source, the first light guide having a guide proximal end;

a second light guide that receives the light energy from the light source, the second light guide having a guide proximal end;

a guide bundle that is in optical communication with the light source, the guide bundle bundling the first light guide and the second light guide, the guide bundle including a first ferrule that engages the guide proximal end of the first light guide and a second ferrule that engages the guide proximal end of the second light guide; and

a receptacle assembly including (i) a receptacle block, (ii) a first receptacle hole that is configured to receive the first ferrule, and (iii) a second receptacle hole that is configured to receive the second ferrule;

wherein the first receptacle hole and the second receptacle hole are formed as v-grooves in the receptacle block;

wherein the receptacle assembly further includes a retainer assembly including (i) a clamping bar in direct contact with the first ferrule and the second ferrule such that the clamping bar applies a retaining force directly onto the first ferrule and the second ferrule, and (ii) a plunger that is configured to contact at least a portion of the first ferrule so that the first ferrule is retained in the first receptacle hole, and at least a portion of the second ferrule so that the second ferrule is retained in the second receptacle hole, the plunger being integrated into the clamping bar.

13 . The catheter system of claim 12 wherein the receptacle assembly further includes a backing plate that is coupled to the receptacle block, the backing plate being configured to engage the first ferrule and the second ferrule.

14 . The catheter system of claim 13 wherein the backing plate includes (i) a first alignment hole that is configured to align a first guide beam with the first light guide, and (ii) a second alignment hole that is configured to align a second guide beam with the second light guide.

15 . The catheter system of claim 12 wherein the first receptacle hole and the second receptacle hole are aligned on a same linear axis as one another.

16 . The catheter system of claim 12 further comprising an alignment guide and an alignment guide receiver that are configured to engage one another to guide alignment between the first ferrule and the first receptacle hole and between the second ferrule and the second receptacle hole; wherein the alignment guide is coupled to one of the guide bundle and the receptacle assembly; and wherein the alignment guide receiver is coupled to the other of the guide bundle and the receptacle assembly.

17 . The catheter system of claim 12 wherein the guide bundle further includes (i) a first ferrule assembly including the first ferrule and a first spring that engages the first ferrule, the first spring being configured to provide an insertion force when the first ferrule is inserted into the first receptacle hole, and (ii) a second ferrule assembly including the second ferrule and a second spring that engages the second ferrule, the second spring being configured to provide an insertion force when the second ferrule is inserted into the second receptacle hole.

18 . The catheter system of claim 12 wherein the light source includes a laser, and wherein each of the first light guide and the second light guide includes an optical fiber.

19 . The catheter system of claim 12 wherein the clamping bar is configured to spread a retaining force across the ferrules so that each ferrule is retained within a corresponding receptacle hole.

20 . A catheter system for treating a treatment site within or adjacent to a vessel wall or a heart valve, the catheter system comprising:

a light source that generates light energy;

a first light guide that receives the light energy from the light source, the first light guide having a guide proximal end;
