A medical delivery device suitable for insertion into a lumen of a patient, the medical device (100, 200) comprising a capsule (110, 120, 210, 220) sized to be inserted into the lumen, the capsule comprising a base member, and an actuation mechanism comprising an actuation member (150, 250, 350) configured for movement relative to the base member along an axis, and an energy source (140, 240, 340) associated with the actuation member for powering the actuation member to move relative to the base member along the axis. The base member and the actuation member define a latch assembly comprising: a) a dissolvable firing member (160, 260, 360), the dissolvable firing member being at least partially dissolvable when subjected to a biological fluid, b) a retainer portion (113, 213, 313) comprised by one of the base member and the actuation member, and c) a movable latch (152, 252, 352) configured for lateral movement relative to the axis, the movable latch defining a first surface with a blocking portion (153, 253, 353), and a second surface (152a, 252a, 352a) configured for interacting with the dissolvable firing member (160, 260, 360). In a pre-firing configuration, the blocking portion (153, 253, 353) of the movable latch engages the retainer portion (113, 213, 313) in a latching engagement, and the second surface (152a, 252a, 352a) of the movable latch interacts with the dissolvable firing member to restrict lateral movement of the movable latch thereby preventing release of the latching engagement. In a firing configuration where the dissolvable firing member (160, 260) has become at least partially dissolved, the movable latch is allowed to move laterally thereby releasing the latching engagement.

The invention is directed to a device (1) for sealingly protective and at the same time stool-discharging tamponade of a circular anastomosis of two ends of the large intestine, as occur for example in the surgical resection of a rectal carcinoma, wherein a thin-walled balloon body (5) is placed in the region of the anastomosis, and the balloon (5), providing a tamponade, is filled with a filling medium in such a way that the lowest possible pressure necessary for the sealing tamponade of the anastomosed portion of the intestine can be maintained continuously, and, even in the event of a peristaltic contraction of the rectosigmoid colon, the pressure predefined by the user is maintained as constant as possible, wherein sufficiently high volumetric flows of the pressurizing medium supplied to and removed from the balloon (5) are achieved, such that the sealing contact between the balloon (5) and the intestinal wall is maintained in all segments of the balloon body in the course of a peristaltic contraction wave miming from the sigmoid to the anus.

A device according to the invention includes a vibrating ingestible capsule and a hollow medicament compartment housing. The vibrating capsule includes a housing, a vibrating agitation mechanism disposed within the housing, a power supply, and a control element. The hollow medicament compartment housing is associated with the housing of the capsule and includes at least one aperture. The hollow of the medicament compartment housing is configured to have the medicament tablet disposed therein. The aperture(s) are dimensioned to enable fluid communication the surrounding environment and the hollow.

The embodiments disclosed herein relate to catheter assemblies. The catheter assemblies can include a multi-lumen catheter, a junction hub, and extension legs. The catheter assemblies can also include a sheath that includes a membrane that is permeable to one or more gases and impermeable to one or more liquids or solids. The catheter assemblies can be configured to deliver food to a patient through a first lumen, and simultaneously vent or aspirate one or more gases from the patient through a second lumen. The catheter assemblies can also include preformed catheters that assume a non-linear three-dimensional shape when in a relaxed state.

Systems, devices and methods are provided for administering a carrier incorporating a therapeutic preparation within a subject. A device includes a carrier, and a launch assembly to deploy the carrier by ejecting the carrier from the device and into internal tissue of the subject. The device detects a status of deployment of the carrier. A system includes a delivery device, a carrier disposed in the delivery device, a launch assembly, and detection circuitry. The launch assembly causes the carrier to exit the delivery device so as to penetrate internal tissue of the subject. The system determines a status of deployment of the carrier using the detection circuitry. A method includes introducing a launch assembly within the subject, the launch assembly coupled to a carrier; deploying, by the launch assembly, the carrier; and detecting a status of deployment of the carrier.

This application presents methods and devices for continuously cleaning a colon by at least partially filling a segment of the colon with liquid and agitating the fluid to dislodge matter adhering to the colon walls. Methods for automatic maintenance of liquid levels in the colon during continuous cleaning are taught.

A system for treating a medical condition comprises a harvesting device, a processing device, and a depositing device. The harvesting device harvests tissue from a mammalian subject at a harvest site. The processing device processes the harvest tissue. The depositing device deposits material in a patient at a deposit site, the material based on the harvested and processed tissue. The deposited material is configured to generate resultant tissue configured to treat the medical condition of the patient. Methods are also provided, the methods including harvesting and processing tissue, and treating a patient by depositing material in the patient, the material being based on the harvested and processed tissue.

Methods and devices for delivering one or more substances within at least one body cavity are provided. The device includes at least one nosepiece including at least one capsule having a volume V.sub.sub of the substances; at least one base in communication with the nosepiece, the base including at least one chamber configured to confine pressurized fluid at volume V.sub.PF and pressure P.sub.PF; and at least one hollow puncturing member. The hollow puncturing member includes at least one end in fluid communication with the nosepiece and a second end in fluid communication with the base. The first and second ends are fluidly interconnected by a hollow tube. The fluid inlet port of the capsule is configured in terms of size and shape to interface in a sealable manner with the one end of the at least one puncturing member.
