A compact catheter assembly and methods of making such a catheter assembly are disclosed. The facing may have lateral tabs and may be separable longitudinally along separable locations in the insulation layer of the assembly. A beach cleaner includes a traveling body with ski members disposed at four corner portions of a frame having a substantially quadrangular shape. The slidably contacting section may be integral with the main body to form a one-piece structure, in which the slidably contacting section is formed of the elastomer, and the elastomer of the main body and the slidably contacting section contain the material having at least one of hydrophilicity and water absorbability. Configurations include one hermetically sealed housing with one or, optionally, two subcutaneous sensing and cardioversion-defibrillation therapy delivery leads or alternatively, two hermetically sealed housings interconnected by a powersignal cable.
