A prostate treatment system having a light delivery device positionable in a transurethral device for treatment of benign prostatic hyperplasia (BPH). The light delivery device includes light generator, such as light emitting diodes (LED), laser diodes (LDs) or a diffusion quartz fiber tip connected to a light generator or a light emitting polymer which produces light at a selected wavelength or waveband or alternative sources of suitable light energy. The treatment device may further include a temperature monitoring system for monitoring the temperature at the treatment site. A light-activated drug is administered to the treatment site prior to light activation. The light-activated drug therapy induces cell death of the target tissue. The device provides a minimally invasive transurethral method for treatment of BPH or prostate cancer.

Method and apparatus for light-activated drug therapy

A perfusion catheter system comprises a main line, a first branch line having a tip at a distal end thereof, and a second branch line having a tip at a distal end thereof. The tip of the first branch line is heavier than the tip of the second branch line. The tip of the first branch line may be weighted. There may be a self-inflating balloon at the tip of the first branch line. There may be a self-inflating balloon at the tip of the second branch line. There may be a clamp disposed along the second branch line. The clamp may include a base, a clamping arm hingedly connected to the base, and an aperture extending through the base. The second branch line may extend through the aperture in the base.

Perfusion catheter system for simultaneous delivery of cardioplegia to the left and right coronary artery

A artificial ventricle comprises an inlet for receiving blood, an outlet for discharging blood, and a chamber disposed between the inlet and the outlet. There is also a mechanism for actuating the artificial ventricle between an expanded configuration and a contracted configuration. In the expanded configuration, blood flows into the inlet. In the contracted configuration, blood flows out of the outlet. There may be a one-way valve at the outlet for preventing blood flow back into the chamber. The one-way valve may be a diaphragm valve. The chamber may have a resilient outer wall. The chamber may have an ovoid shape.

Artificial ventricles

A cardiotomy suction tube system comprises a main line, a first flexible branch line in fluid communication with the main line, a second flexible branch line in selective fluid communication with the main line, and a rigid branch line in selective fluid communication with the main line. A valve mechanism selectively places either the second flexible branch line or the rigid line in fluid communication with the main line. The first flexible branch line may be provided with a weighted suction tip which gravitates to a low point in an operative field. The second flexible branch line may be provided with a weighted suction tip which gravitates to a low point in an operative field.

Cardiotomy suction tube system with multiple tips

A ventricle assist device comprises an inlet for receiving blood, an outlet for discharging blood, and a chamber disposed between the inlet and the outlet. There is also a means for actuating the ventricle assist device between an expanded configuration and a contracted configuration. In the expanded configuration blood flows into the inlet. In the contracted configuration blood flows out of the outlet. There may be a one-way valve at the outlet for preventing blood flow back into the chamber. The one-way valve is a diaphragm valve. The chamber may have a resilient outer wall. The chamber may have an ovoid shape.
