Abstract: A computing device provides enhancement of the capabilities of text messaging applications that execute on user devices. The computing device includes a processor that receives a text message via a network from a user device, the text message including a character representation of a product bundle of a merchant. The processor determines bundle data for the product bundle by referencing a database using the character representation. The processor provides one or more text messages via the network to the user device with transaction data including the bundle data, payment data, and shipping data. The processor receives a text message via the network from the user device confirming the transaction data. The user may use text commands presented by the computing device or natural language conversation in the text messages to the computing device to modify the transaction data and perform other ecommerce actions.

Abstract: A catheter assembly is provided with a first visual device and a second visual device. The second visual device is movable with respect to the first visual device to provide image feedback of a lesion from a different prospective than the first visual device. The second visual device can be moved before, contemporaneously with, or subsequent to a diagnostic or therapeutic procedure. The second visual device can include an elongated tube that can be extended into or retracted out from an insertion tube of the catheter assembly.
