Abstract
System and components for inducing pleurodesis or other sclerosis or desired adhesion conditions to treat a patient, while minimizing likelihood of tissue damage from direct application of sclerosis-enhancing materials. A tube device is provided that is configured to elute sclerosis-enhancing material and/or other medicaments via a fenestrated drainage tube. The assembly of tube device with outer (typically drainage) tube may include one or more features configured to enhance delivery of medicament and/or drainage through the same assembly.
Claims20
An injection catheter assembly comprising:
- an elongate flexible outer tube body including:
- a distal length configured to indwell a patient body trunk cavity;
- and
- at least one body lumen extending longitudinally through at least a lengthwise portion of the distal length, the lumen substantially defined by an inner diameter surface of the tube body;
- the distal length including at least one aperture disposed through a wall of the body, and in fluid communication with the body lumen;
- wherein at least one portion of the distal length is configured as an injection portion that includes at least one surface constructed to permit passage therethrough of a sclerotic agent;
- and
- a flexible, curved inner cannula body dimensioned for passage through, the body lumen of the outer tube body, the inner cannula body including:
- a memory-material portion imposing a pre-determined curve along a length of the inner cannula body;
- an injection lumen extending longitudinally through at least a lengthwise portion of the inner cannula body;
- and
- at least one distal-region opening configured for dispensing a medicament.
