1. A medical device with a proximal end for insertion into a body of a living being and an axially opposite distal end, the device comprising: a tip which in a first position forms the proximal end of the device, a drainage section forming a conduit extending in an axial direction of the device, and a retention section extending between the draining section and the tip, wherein the tip is operable between the first position and a second position so as to move the retention section between a first configuration and a second configuration, in which second configuration the retention section is expanded in a direction transverse to the axial direction. The conduit and the tip may be dimensioned to allow the tip to be received within the conduit. One advantage of such a system is that the retention system may be retracted entirely into the conduit so as to make insertion and retraction of the device more comfortable for the patient.

Methods for manufacturing fabric-reinforced weatherstrip include incorporating a fabric application step into a process for making coated substrates. In one embodiment, a strip of the fabric from a roll of material may be applied directly onto a coating after it has been applied in a coat die to a foam profile, while the coating is still in the molten state. Alternatively, a fabric application plate may be attached to an upstream side of coating die with a fabric feed channel cut into the plate. The fabric follows the channel to contact and mate with the foam profile. The fabric applicator plate may be configured so as to exert pressure on only the part of the product where the fabric is being applied. Ultrasonic welding techniques may also be employed.

A towable trailored standing tree baler provides independent maneuverability with sufficient structural strength required for baling large trees. A telescopic wheeled frame provides ground support directly underneath a tree branch compression ring and therefore provides a strong structural foundation for pushing the ring upward. The support wheels of the frame can be both steered and tilted so that the apparatus can be centered on the tree even on uneven ground. A compression ring lifting boom utilizes an interconnecting rotation arm between the end of the boom and the compression ring so that the ring may be positioned at a very low starting point close to the ground and then moved accurately upwardly with the circumference of the ring being held level and centered. A specialized lining material on the ring reduces friction against the tree limb bark and therefore reduces tree limb damage.
