Block copolymer particles, and related compositions and methods, are disclosed.

Block copolymer particles

A medical device for use within a body cavity comprising an elongated body portion and a retention module. The retention module comprises a fixation element and a tether connector. The tether connector and fixation element permit the device to move a predetermined distance longitudinally. The tether connector reduces ureteral reflux, and minimizes irritation and patient discomfort. The fixation element and the tether connector further function as a graspable structure for removal of the stent.

Ureteral stents and related methods

A medical lubricant suitable for injection into the blood stream of a patient. The lubricant is suitable for use with rotating equipment such as atherectomy drive shafts moving within sheaths and over guide wires and other minimally invasive medical devices introduced into a patient through a catheter like instrument. The lubricant is an oil-in-water emulsion including a surfactant, a co-surfactant, and a pH buffer. The lubricant can further include a cryogenic agent and a pH adjusting agent. One lubricant includes olive oil as an emulsified oil, egg yolk phospholipid as a surfactant, sodium deoxycholate as a co-surfactant, glycerin as a cryogenic agent, L-histidine as a pH buffer, and is pH adjusted using sodium hydroxide. The lubricant also includes a therapeutic agent. The lubricant can withstand freeze/thaw cycles as well as saline dilution, heating, and shear stress without significant creaming, separation, or unacceptable increases in oil droplet size.
