Abstract: Aspects of a device are described. One aspect is a device comprising: a housing having a first portion engageable with a scope, and a second portion engageable with a handle of a retrieval device; a platform that is movable relative to the housing, and engageable with a slider of the retrieval device; and a link assembly that is coupled the housing and the platform, and operable to move the platform and slider relative to the housing and handle. Aspects of related devices and systems also are described.

Abstract: A medical device may include a handle having a handle lumen extending therethrough. The medical device further may include a first body shaft including a first body shaft lumen in direct communication with the handle lumen and an RF electrode tip may be positioned at a distal end of the first body shaft. The RF electrode tip may include a lumen extending therethrough and in direct communication with the lumen of the first body shaft. Additionally, an energy delivery wire may be electrically coupled with the RF electrode tip.

Abstract: An insertion device may include a hollow handle and a shaft extending distally of the hollow handle. The insertion device may also include a cap coupled to a distal end of the shaft. The cap may include a camera and an LED coupled thereto.

Abstract: A medical device having a valve member and a securing member is provided. The valve member is configured to be positioned inside a bodily passageway. The valve member includes a plurality of flaps configured to move from a first position to a second position at a predetermined pressure or in response to being exposed to a predetermined pressure. The securing member is configured to be positioned outside the bodily passageway. The securing member is configured to help retain the valve member in place within the bodily passageway.

Abstract: A urinary stent includes an elongate member that defines a lumen extending therethrough and that is configured to be disposed at least partially within a prostatic portion of a urethra of a patient. The elongate member includes a collapsible portion disposed at a proximal end portion of the elongate member. The collapsible portion has a first configuration in which an outer perimeter at a proximal end of the collapsible portion is substantially equal to an outer perimeter of a remaining portion of the elongate member and a second configuration in which the outer perimeter at the proximal end of the collapsible portion is smaller than the outer perimeter of the remaining portion of the elongate member.

Abstract: A needle biopsy system for marking a sampling site is described.

Abstract: Medical devices can be positioned within a patient by use of apparatus and methods according to the invention. The apparatus and methods permit insertion of the medical devices into various locations of the patient's body without requiring removal and reinsertion of already-inserted medical devices. The apparatus and methods are typically used to place medical devices into a male patient's urinary system to treat a disease or condition. The medical devices can be cryoablation probes that are inserted into the prostate gland to treat prostate cancer, for example.
